Backing up files on Android or how to make a backup of Android. How to make a backup on Android

Data-lazy-type="image" data-src="http://androidkak.ru/wp-content/uploads/2017/06/android-backup..jpg 356w, http://androidkak.ru/wp- content/uploads/2017/06/android-backup-300x169.jpg 300w" sizes="(max-width: 356px) 100vw, 356px"> Mobile device users are often interested in how to make a firmware backup on Android themselves. There is a simple and reliable way to create a backup copy to restore your smartphone.

A backup allows you to save all data and current phone settings so that they can be restored at any time from a backup copy. It is recorded on an SD card, after which it can be transferred to any other medium.

What is backup and why is it needed?

Those who are interested in how to backup Android firmware need to know that this procedure is very similar to creating a copy of the hard drive for a PC before replacing it. Benefits of full backup on Android:

You don't have to worry about saving some of your phone's specific data (like text messages) because the Nandroid app can copy absolutely everything.
You can try using a new ROM created by independent developers. If for some reason it does not work, then there is always the opportunity to return to the stock operating system.
Using backup, you can restore not only your phone, but also other devices of the same model. If your smartphone was lost, you can buy the same one and restore all the information on it.

Firstly, with the help of backup you can restore either everything or nothing. In other words, you cannot restore just games or photos.
Secondly, there is always a small chance that some kind of failure will occur.

The Nandroid app has been well tested and is generally stable, but there is a chance that unexpected issues may arise.

It is recommended that you save your extremely important data somewhere before you begin the operation. However, your contacts and app list are already backed up thanks to Google, so there's no need to copy them. Backup is a simpler process than it might seem at first glance. To complete it, the user may need from 10 minutes to 1 hour (depending on his skills).

Preparing for backup

First you need to get full access to all the features of your Android device. If the user unlocks them, they can customize their phone however they want. Accessing the root of a mobile device offers some important benefits. For example, without it it is impossible to make a full backup, because the phone simply will not give the user such rights.

On different device models, gaining access to the root can be done in different ways. Using the Google search engine, you can find instructions for a specific smartphone model and a specific version of the Android operating system.

The Nandroid application allows you to backup all information on your mobile device so that you can restore the system in the future.

There are different ways to use Nandroid, but the simplest one is ClockworkMod ROM Manager, which has a whole host of useful features. It can only be used on devices with root permissions. The application can be downloaded through the Android Market.

To do this you need to do the following:

enter the Android Market by first downloading a special application;
find ClockworkMod ROM Manager using the search bar;
install the program.

Backup Process

Now you can make a backup. This process will take about 5-10 minutes, after which a new folder should appear on the SD card. This directory will contain all the files needed for recovery (they form a full backup).

After we have downloaded everything we need, we can, for example, create an Android folder in the root of some folder and organize the unpacked contents of the archives into folders, i.e. drivers in the Drivers folder, Platform Tools in a separate folder, SP Flash Tool in a separate folder, MTK Droid Tools also in a separate one.

Next, enable Developer Mode on your device and activate USB debugging. Those. First, go to Settings -> About phone (About device) and click several times (5-7) on the “Build number” until a message appears stating that Developer Mode is activated. Next, go to the Settings menu -> For developers and check the box for “USB debugging”:

After that, we connect the device to the PC and install the ADB drivers (that is, either by running AdbDriverInstaller.exe from the archive, or by opening the device manager and manually specifying the path to the drivers in the Android ADB driver x64 folder for an unknown device). The result should look like this (Device Manager):

The Android ADB Interface device in the device manager confirms that we are ready for the next step.

We wait until the device is detected in it and click the “Block Map” button:

Then click the “Create scatter file” button and save the resulting file (for me it was called MT6582_Android_scatter.txt) to disk. At this point, the preparation stage is completed and you can proceed directly to reading the data.

Open the resulting file in Notepad++ or Word (note that regular notepad will not work) and find the line partition_name: CACHE in it:

And remember what is written in the linear_start_addr column, in this case it is 0x3E900000.

We disconnect the phone from the PC and turn it off, i.e. hold the power off button and select “Power off” in the menu, you can also disconnect and insert the battery. Next, launch the SP Flash Tool and go to the Readback tab. Next, click the Add button. As a result, one row will appear in the table:

We click on it, we are asked to select a location to save the ROM_0 file, select the folder in which we want to save it and on the next screen in the Length field we enter the number we remembered earlier (linear_start_addr):

The end result should be something like this:

Then we connect the switched off phone (!) to the PC. At this point, it is advisable to open the device manager. For now, we don’t press any buttons in the SP Flash Tool on this screen!

At the moment of connection, an unknown MT65xx PreLoader device will be detected and the OS will prompt you to install drivers for it. The picture below clearly shows this. It’s better to open the device manager immediately before connecting the phone in order to “catch” the moment the MT65xx PreLoader appears. If the device appears, but the OS does not offer to automatically install drivers, then this must be done manually by right-clicking on the MT65xx PreLoader device.

Select “Search for drivers on this computer” and indicate the folder in which the unpacked contents of the mtk_xp_vista_7_8_x32_x64.zip archive are located (i.e. by this point you should unpack the archive somewhere). After the drivers are successfully installed, the picture in the device manager should change to this:

If the drivers are installed, you can proceed to the next step. Please note that when you connect the phone, the Preloader USB VCOM Port may appear for only a few seconds - this is normal, our task at this stage is to install the phone drivers so that it is detected exactly as the Preloader USB VCOM Port, and not the unknown MT65xx PreLoader device. If you suddenly did not have time to install the drivers, and the phone turned on, take out the battery, disconnect the phone, insert the battery, connect the phone and repeat the procedure.

Once we are sure that the drivers are installed, we disconnect the phone from the PC. We turn it off, in the open SP Flash Tool we press the Readback button and connect the turned off phone to the PC. After this, we will go through the process of reading the firmware from the phone:

Many people write about the difficulties that arise precisely at this step. I'll try to explain in a little more detail. After you press the Readback button, SP Flash Tool goes into standby mode for the phone to connect, i.e. It is assumed that before this you managed to catch the moment when your switched off phone is identified as MT65xx PreLoader and installed drivers on it so that Preloader USB VCOM Port appears in the COM ports. If suddenly for some reason the SP Flash Tool wrote an error, or the phone did not have time to connect, the following method can help (everything described is only true if you installed the drivers correctly and when you connect the phone, Preloader USB VCOM Port appears): disconnect the phone from the PC, remove the battery, press the Readback button, connect the phone with the battery removed. In the SP Flash Tool there will be a red bar (Download), during this time we quickly insert the battery back, if we have time, then a blue Readback bar will appear with percentages, as in the picture:

We are waiting for the process to complete. Creating a backup can take 10-15 minutes. Just look at the running percentages and don’t touch anything 😉 At the end of the reading procedure, you will see the message Readback Ok:

While we are doing Backup, it’s time to explain what a scatter file is and what the ROM_0 file is, which we will receive as an output. The phone's memory is a regular EMMC Flash, which is divided into specific sections. A Scatter file is a section description file (for example, Scatter has sections PRELOADER, RECOVERY, LOGO, ANDROID, etc.). The purpose of the partitions is different, for example, Recovery contains the recovery image, logo contains the logo used when loading the system, Android contains the system image, etc. The ROM_0 file that we get as an output is essentially a continuous dump of EMMC Flash in one file. But in order to use the resulting firmware backup, for example, to restore another similar device, we will still need to split it into partitions. Here I will describe several ways to do this. The first and most common is through MTK Droid Tools. Let's say we already have a ROM_0 file made using the SP Flash Tool.

We turn on the power of the device (phone) and let it boot, after which we launch MTK Droid Tools again (the USB debugging mode on the phone must, of course, be turned on, and the ADB drivers must be installed on the PC), go to the root, backup, recovery tab and click the “Create backup from ROM_ flash drive” button:

We select the ROM_0 we obtained in the previous step and in the log window we see something like the following:

— Save folder on the computer: E:\Android\MtkDroidTools\backups\KINGSING_S1_141117_ForFlashtoolFromReadBack_150512-005322\
— scatter is saved in the file:
E:\Work\Megaphone Login Plus\MtkDroidTools\backups\KINGSING_S1_141117_ForFlashtoolFromReadBack_150512-005322\MT6582_Android_scatter.txtcopying completed

- pro_info ...copied
- nvram.bin...copied
- protect_f ...copied
- protect_s...copied
-seccfg...copied
- uboot.bin...copied
- boot.img ... copied
…

Well, etc. Now in the save folder, for me it is E:\Android\MtkDroidTools\backups\ we have a folder with a complete backup of our firmware, divided into sections (i.e., each section in a separate file):

This completes the process of creating Backup firmware. If you just wanted to find out how to make backup firmware using the SP Flash Tool and you succeeded, you don’t have to read further.

For advanced

What to do if MTK Droid Tools does not “see” the phone? Or is it impossible to create a scatter file or split the resulting ROM_0 file into sections? How to get a partition map and is it possible to “cut” the ROM_0 file manually? There is such a possibility. To get a partition map on MTK 65xx you need to give a command in the ADB console - i.e. run adb shell in the console and type this command there:

If suddenly the phone is not visible through ADB for some reason (in this case, I advise you to read the ADB manual, there may be a problem with the VEN_ID of the device and you just need to register it in %USERPROFILE%\.android\adb_usb.ini, then the same command can be given in the phone itself by installing Terminal Emulator for Android from Google Play:

As you can see, the result is exactly the same and the linear_start_address of the cache section can be taken from here. Yes, by the way, in new devices, for example based on MTK 6752, such as Beeline Pro, ZTE Q Lux, etc. The partition map can be obtained using cat /proc/partinfo. MTK Droid Tools does not work with these devices at all.

We now have a method for obtaining the start address of the cache section, which is needed to obtain ROM_0 using the SP Flash Tool. We also know the addresses (offsets) and sizes of each partition. Those. To “cut” ROM_0 into partitions, we don’t need to use MTK Droid Tools. This can be done manually in any Hex editor that supports the function of selecting and saving a block to a file (I use the console HIEW). Well, as an example, let’s “cut out” the Recovery partition from the resulting ROM_0 file.

We know (from scatter or from dumchar_info) its linear_start_addr: 0x4180000 and partition_size: 0x1000000. Open ROM_0 in HIEW and go to 0x4180000. Those. in the console we make hiew32 ROM_0, then press F5 and enter the address of the beginning of the partition - 4180000:

As you can see from 4180000 we have the ANDROID! signature, which tells us that we are on the right track 😉 The end of partition address is calculated as linear_start_addr+partition_size-1 = 0x517FFFF in our case. We press in HIEW * (the asterisk on the additional keyboard) to start selecting the block (if we move the arrows up / down / right / left, we see how the block begins to be highlighted in color) and either go down to 0x517FFFF, or do it through F5:

And we finish selecting the block, again through the “gray” * (on the additional keyboard). After that, press F2 - Put block (saving the block to a file):

And we have the recovery section written down. In the same way, you can cut any other partition from ROM_0. As you understand, we don’t need MTK Droid Tool at all.

To simplify the procedure, you can also write a script / program that will do this automatically for all sections, but to be honest, I don’t have enough time for this, and this task does not arise very often, so HIEW is quite enough for these purposes .

p.s. That's all for now... the post turned out to be a “draft version”, because... I wrote it in a hurry, maybe I’ll add to it later if there are any unclear points. And of course, as always, I will respond to your comments and questions...

p.p.s. As they managed to correct me a little, /proc/dumchar_info does not contain linear_start_addr from the scatter, but physical_start_addr. Those. in the example given for the recovery partition we have:

linear_start_addr: 0x4180000
physical_start_addr: 0x2D80000
partition_size: 0x1000000

And in /proc/dumchar_info we see exactly physical_start_addr in the StartAddr column. But if we look at the size of the first partition (preloader), it becomes clear how to convert physical_start_addr to linear_start_addr; if you add 0x1400000 to 0x2D80000 (this is exactly the size of the preloader), then you get 0x4180000.

To never worry about the safety of your data, you need to periodically backup your Android device. An Android device accumulates system errors as it operates, its memory becomes increasingly filled with your applications, pictures, SMS, contacts and other information. It all comes down to the fact that the device begins to work incorrectly, responds slowly to commands, or involuntarily deletes your personal data. This is not the most pleasant situation, so it is important to carry out the backup procedure.

While your Android device is still functioning adequately, make a backup copy by saving it to a flash card or computer. Then, when you return the system to its original settings, you can painlessly restore the necessary contacts, messages, calendar entries, videos, pictures and applications.

Some Android device users never even think about the need for a backup procedure. Usually they use the phone until it starts to glitch, and then they just get a new device, without even thinking about the possibility of caring for the gadget.

The complete procedure for returning the device to its original settings is carried out in 4 stages:

creating a backup copy;
backup;
data reset;
recovery of necessary data;

Creating a backup copy is easy; you don’t need to download applications or get root rights. All backup tools are already included in the Android system. The developers offer users several ways to make a backup:

copying data to SD card;
storing data on a Google server.

How to make a backup

There are no particular difficulties when using the first method. All pictures and videos are mostly initially stored on an external memory card, which significantly speeds up the process of copying data. First you need to open the menu and go to settings. Required items: “Restore and reset - Data backup” and “Backup to SD card”. Depending on the amount of information on your device, the process will take from 5 to 40 seconds. After this, you can safely take out the SD card and save the archive to your computer or leave it so that if necessary, the necessary data is always at hand.

Saving files on Google servers will take a little longer. But you don’t have to think about saving applications if they were downloaded through the Play Market. Your account “remembers” every application and key ever downloaded using it. When you're done with the backup, you can simply reinstall the programs you need. The list of applications can be found along the path: “Menu - My applications - All”.

Contacts can also be saved using a Google account. To do this, open the settings and find the “Accounts - Google” item. Through it you synchronize your device with mail. Check the boxes next to the data you want to save.

Photos, if you do not want to save them on the SD card, can be saved to your Google+ account. Initially, the service was positioned as a social network, but it is also often used as a storage of contacts and images from devices. Just like in other social networks, you can open and close access to albums and photos. There is a 5 GB limit on the site.

If you have a larger number of photos, you can simply transfer them via a USB cable to your computer.

Reset to factory settings

After completing the process of copying your data, you can proceed directly to returning to the native settings. The procedure is inherently intuitive. Go to settings and find the item “Return to factory settings - Reset settings”.

For experienced users who have root rights, there are several more ways to make a backup. The simplest: backup using the Recovery menu. This method is good if the device has already been brought to the point where the operating system does not load. To call the recovery menu, you need to hold down the power button and volume up/down; in some models, power on + Home. You can navigate through the menu using the volume buttons, and select items by pressing the power button once.

First of all, select “backup and restore”. Next, a list of possible commands will appear. You need to select “backup”. After the device has finished recording all data, you need to select the “restore” command. The system will reboot and the device can be started.

To make the backup procedure completely convenient, you can install the Titanum backup application. Quite a convenient and fast utility for creating a backup copy of all applications and data on your device. Helps when changing firmware or banal saving during a possible reset. The program is free and available in the play market.

For prevention, it would be best if you start using the system from scratch, then you can avoid repeating old mistakes. Because when you return old applications, you can accidentally cause the same problems that you so wanted to get rid of.

It is better to backup the firmware at least once every six months. Then all your data will be securely stored. And you can always transfer them to another device or return to the old one after resetting all settings to factory settings.

Nothing lasts forever, and, oddly enough, including various mobile gadgets and devices. Have you ever encountered a situation where your phone ended up in the hands of third parties (simple theft) or was simply smashed at speed or from the roof of a building? In 50% of cases, the data can be recovered, because the SD card remains intact or the phone’s memory is not damaged, but you have to pay huge sums of money (from 1000 to 10,000) to restore information in various service centers, and no one guarantees you 100 % data return.

What to do in this case? Any user, ahead of events, can predict such a situation and make a backup copy of the data in advance. Even if time passes between the last backup and the loss of access to the phone, the percentage of lost information will be kept to a minimum. We will tell you how to make a backup copy of Android, what methods are provided for this and how often such operations need to be performed.

Why do you need a backup and what tools to use?

Backup involves creating a copy of certain information on any device or system. This material is about the Android operating system, which is installed on smartphones and tablets. The copy can store not only data from SMS messages or contacts, calendars, but also all applications and programs installed on the phone.

To make a backup copy, you must first decide what exactly you need to save. For Android, there are a huge number of methods, each of which allows you to backup data without any problems. In this article we will describe the main ones and indicate which data is most suitable for working with which method.

Backup contacts, SMS, calendars in Android

Let's say that you need to make copies of only contacts or along with them also standard text information, for example, calendars, call logs, etc. The following methods are suitable for this:

Standard contact synchronization in Google
Specialized programs, for example, Super Backup, Helium

We described the process of synchronizing contacts in the article -.

Any user can work with the programs listed above without any problems. They are provided free of charge on Google Play. The described method is suitable for those people who need to make a backup without applications and games!

Full backup of data in Android - popular methods

If you decide to make a complete copy of the information on your device, including applications and games, you can use standard operating system tools or install an additional program that will create a backup of your data with the specified parameters in a few minutes.

Here is the main list of tools for work:

Standard Android settings
Recovery Mode
Titanium Backup program (requires root rights on the device)
Safe Backup program (no root rights required)

Creating an Android backup through system settings

Few people know, but Android has standard functionality for creating copies. And so, the procedure is as follows:

Open your phone's Settings and select the All Settings tab. Next, find the “Backup and Reset” item. In some versions of Android, this item is located immediately after the settings.
A standard control menu will open in front of you, which has about a dozen tabs for managing data on your phone. We are interested in the “Backup” item. Specify a name for the future file with copies.
Next, in the menu that opens, select all types of data that should be saved. Please note that in addition to applications (a complete list of games and programs), you can also copy SMS, which is very important, contacts (although Google synchronization is available), call lists and much more.
Be sure to select the location at the bottom of the window where the data will be saved. If your phone has an SD card, the backup can be saved there. Once a copy is created, it can be transferred to a computer, sent by mail, or transferred via Bluetooth.
Attention! To use this copy in the future, select “Data Recovery” and follow the system prompts.

Creating a backup via recovery mode

In the article “” we talked about how to switch to recovery mode on most devices (Home key combination, volume up, volume down). Look at the material and basic combinations, go to this mode.

Let's say you entered this mode. A menu will appear on your screen in which you need to select the Backup and restore tab.
Next, click on the Backup menu item, after which you will need to wait from 5 to 30 minutes, depending on the amount of information on your device and its system characteristics.

Backing up applications with Titanium Backup

This is a universal tool for working with backups. With this program you can not only create, but also restore any backup on your device. Just keep in mind that this application requires root rights!

The program is provided in two versions: free and paid (from 247 rubles), however, for standard operations the first option will be sufficient. All files are saved into a single zip file, which can be transferred to another device or saved to a USB drive.

To make a copy, follow these steps:

Download and install Titanium Backup from Google Play. The program has many built-in language packages, including Russian.
Open the program. A notification will appear indicating that you have root rights. Allow the app full access to your data. We recommend that you carefully read each item in this software, because there are a lot of settings here, as well as additional menu items, so it’s quite easy for an inexperienced user to get confused.
Select the Backups tab. The system will display a complete list of applications and icons next to them. If the icon displays a triangle with a question, it means that a copy of this program has not yet been created previously. The location of programs and games is also displayed there.
Select all applications that need to be packed into backup. Next, click the “Save” button. All saved programs will change the icon next to the name from a triangle to a cheerful smiley face.

This was the process of creating copies specifically for applications! To restore them in the future, you will also need Titanium Backup. Only this time you will have to select a full or partial list of applications by checking the boxes and clicking the “Restore” button. Recovery is available in several modes:

Only data from programs (for example, if you have the applications themselves installed).
Software only (if you don’t have any software).
Software + Data (full recovery of a copy of applications with all data).

Creating a complete copy of data in Titanium Backup (paid version)

The difference between the paid version and the free version is that in the first version you will have access to additional options for creating copies. In addition to applications, it is possible to save system data, user software, check copies and much more.

After purchasing the paid version, you will have an additional item to manage all processes. Believe me, the price of 247 rubles is a minimal loss for you if the information is really important.

Creating a copy of Android in the Safe Backup program

Almost all programs require root rights to create copies. But what should a person do if he does not have such access? In this case, we suggest you use the Safe Backup tool. The program is distributed free of charge, has only a few menu items (which is very convenient) with a Russian interface.

Download and install the application on Google Play.
Open the program and select "Save".
Next, provide a complete list of information that will need to be added to the backup.
Specify the location on the card or phone where the copy will be stored.

To restore a previously created backup, you will need to click the “Restore” button and specify the file version.

conclusions

This is not a complete list of possible ways to create a copy of Android, but they will be fully sufficient to save at least 90% of the most important information.

And one more important tip! All apps are saved to your Google Play account. If the data (settings, progress in games) is not important to you, then you don’t need to create copies. It will be enough to go to the Play Store and restore previously downloaded programs and games. All authorization data will have to be entered again.

Modern smartphones store a huge amount of necessary and important information, and each user customizes the phone individually. And so, when switching to a new device, the Android owner is faced with a situation where the operating system needs to be configured again. The ideal solution here is a deep or partial backup. But not everyone knows how to make a full Android backup quickly and safely using a tablet or phone without losing important data.

How to backup individual applications on Android

It is not always necessary to copy the entire system, and the process is quite painstaking. If you need to save only specific programs, we recommend using this method. And here the ideal option is the Helium application.

This tool can be freely downloaded from . It works on two “bases”: either provision and all frauds are carried out only on a smartphone, or access to a PC if you do not have “Superuser” mode.

The application allows you to save copies to and in cloud storages, namely Drobox, Google Drive and Box, which is very convenient.

She can:

Back up the history of incoming and outgoing calls;
Backup of applications and their settings;
Backup SMS and contacts.

The paid premium version has more advanced functionality, but if you only need to save, for example, games, the free version will be enough.

The application works perfectly on the latest versions of the operating system, mainly Android 7.0, 7.1 and 8.0. Now let’s look at what actions we will perform in it:

Download and install the application on your phone. If there is no root rights, repeat this procedure on the computer. Versions are available for both Windows and Mac. Drivers are also required for the PC. You can find them on the official website of the manufacturer of the connected smartphone.
Now let's proceed directly to the backup operation itself. To do this, open the application on the device. If necessary, we connect via a wire to the computer. We are offered several options: a full backup of the phone or only specific applications. Please note that you can copy the entire program with data, or just the data.
After all the checkboxes are checked, click "Backup". Choose where to save. If to the Cloud, then indicate the address; if to a computer, open the service with the IP address and transfer it to the search bar of the browser. There we allow copying. Ready. The copies were created successfully.

But here things are a little more complicated, since we need a complete saved copy of Android. Of course, it will take up more space, and there are several different ways to create it.

Backup via system option (No Root)

The easiest and most comfortable option, suitable for beginners and simply users who did not want to waste their time. Opening "Settings", go to point "System" – "Backup", in the location we select Google Drive. Made. The following information will be saved:

Standard settings (language, time and date);
Wi-Fi hotspots and passwords, if activated;
Screen settings (wallpaper, themes, brightness);
Applications (in most cases just a list, but not internal settings and achievements in games);
Content located in Google Calendar;
Materials stored in Gmail, individual mail settings.

Root rights are not required; their presence does not affect the quality of the backup in any way.

Unfortunately, failures during the backup process are possible, which is why many users complain about the insufficient amount of stored information. And on some devices, such a system function refuses to work at all; this may affect phones with an operating system lower than Android 6.0.

Backup Android using FlashTool (No Root)

This is a more serious and difficult procedure that allows you to back up the entire firmware. There will be many stages, and For users who are not confident in their abilities and technical knowledge, we do not recommend this option! But if you are an experienced Android expert, then you can safely get started.

To begin with, we prepare all the necessary materials so that during the backup process we do not have to be distracted by them.

Download the program itself directly from the official website of the developer ( flashtool.net);
We find original firmware, made specifically for your smartphone;
If there are no MTK drivers on your computer, download them.
We gain access to the PC, since without it backup is impossible here, we check the functionality of the USB cable and the serviceability of the connectors.
Next, extract two files from the firmware, namely the name of the number with permission txt And weg_l.bin. We move these materials to a separate, empty folder.
We also place the folder where the software is stored there.
Launch the previously downloaded FlashTool program on behalf of the administrator, this is a prerequisite.
A page opens where you need specify the path to scatter.txt using a built-in conventional conductor.
A new screen should appear where the memory blocks are located. It is necessary to make a backup with them. For this go to the “Memory Test” tab. We check the boxes next to the first five points.
Turn off the phone, click on the computer "Start".
Now we connect the smartphone using USB.
The information begins to be read and displayed on the screen. Once the process is completed, disconnect the device from the personal computer.
Opening "Notebook" and transfer the received data there. Please note that empty sectors do not need to be copied. Save and close the notepad.
We return to the FlashTool main page again, uncheck the checkbox next to the first item.
Open the section “Readback” – “Add”. A new line appears, which we double-click on.
We indicate where exactly to save the backup and come up with a name.
A small menu appears asking you to specify settings for each sector. Yes, yes, a separate memory block needs separate configuration. We change only the “Length” column, to which we add block data from a saved notebook.
Click "OK" and press the top button "Read Back"
And the last final step: reconnect the phone and watch the copying process. At the end, a green icon should appear indicating that the operation is complete. Made! Now we repeat similar actions with the remaining sectors.

After the backup is completed, the files can be moved to any cloud storage, because if some major trouble happens to your computer or hard drive, the saved information will be lost, don’t risk it!

So we made a backup on Android via FlashTool using a computer, now we are trying the following method.

Backup via Titanium Backup (Root)

Quite light and comfortable option using special Titanium Backup program. You can download it without any problems from Google Play and install it in the standard way.

Now we launch the application and give it access to root rights. Yes, “Superuser” mode is required here, and this, in principle, is the main disadvantage of this utility. Click on the checkmark image in the upper right corner to go to the page "Batch Actions" and choose what data we want to save. Click next to what you want "Start".

Another decent option that works on all devices, but from experience I will say that it is much easier than the FlashTool method. For this we need recovery mode. Of course, the most popular and most functional is TWRP, allowing you to install custom firmware, different kernels, but for backup is quite suitable and stock. Begin:

Make sure your smartphone has more than 60% charge.
Turn off the phone, after about 30 seconds press the power button and the volume rocker down or up, differently on different models.
Next, an image of an Android robot with an exclamation mark may appear. If this happened - press the same key combination, but do not hold it. Did you immediately go to recovery? Then we skip this point.
Now we find ourselves in the recovery menu itself, only here touch input no longer works. We will switch with keys: the volume rocker, accordingly, is a command "up", volume down rocker – "down", on/off button – "OK".
We go down to the point "backup/restore» , click "backup". The copying procedure begins, which takes on average up to 10 minutes. During this period of time, we don’t press anything, we don’t turn on the smartphone, we just wait.
When the operation ends, we reboot the smartphone. That's all, ready, the backup of the Android firmware is done.

IMEI, as we know, is the unique identification number of a smartphone. And quite often there are situations when this number needs to be saved, that is, backed up. For this we will use special program Root Explorer. Root rights are also required for it to work.

We open the application, through it we go to the root of the device, where the one we need is located efs folder We carry out a long press, after which an additional mini-menu appears, where we select "Create archive"(Archive permission is at your discretion).

Backing up instant messengers

Messengers for the modern user are simply a necessary thing, helping both to communicate with friends and, for example, to send a photo of completed work to the boss. Let's look at the example of WhatsApp. It stores a huge amount of necessary information: important messages, images, phone numbers. And the ideal way not to lose such materials is to make a backup. How to do it on WhatsApp?

Built-in backup option

All popular instant messengers have their own backup function, which allows you to save the necessary materials directly from the application itself. WhatsApp is no exception.

Begin:

Find the application, open the menu;
Click "Settings", now go to the tab "Chats" and click "Backup copy".
Choose saving to Google Drive and setting the frequency of saving.
If you have several Google accounts, select the desired one in the window that appears. Haven't registered or logged in to your account yet? Then click "Add account".
And in the last column we select the network under which the copying will take place. Don't forget that using mobile Internet may result in additional charges for the megabytes used. “Applications”, check the box next to it “WhatsApp” – “Save”. The backup made, or rather the path to save it, can be found in the section "Archived".
Backup using Restore Transfer
Another decent app created by the developer Trustlool Apps. Fully translated into Russian, the interface is simple and clear. Besides, There is a huge plus for beginners and inexperienced users - root rights are not needed.
Immediately after launching the utility, we see a list of programs and games installed on the device. We look for our messenger, put a tick next to it and click on the big gray button located below - "Backup"
To do this, go to the application, open the section there "Archive", find the necessary materials, and after checking the box, click "Restore".
Is Super Backup free? I heard that you have to pay for it.
There are two versions of this tool: basic, that is, having small but useful functionality, and extended premium. In the first option, no payment is required, but for the second you will have to pay. Both versions are freely available on Google Play.
As you can see, on Android it’s quite easy to make a backup; you can save firmware, instant messengers, applications, and always have the necessary information at hand. The most important thing is to be attentive and strictly follow the instructions. Good luck!
