Recovering data from internal memory of Android. How to recover deleted data and files on Android. PC programs

Tutorial

Nowadays, more and more smartphones come without an SD-card slot, and information has to be stored on the built-in memory with access to it via MTP. This connection mode does not allow using standard means to restore phone data after a wipe or accidental deletion.

Today, using the example of a combination of Xiaomi Mi2s and Windows 8.1, I will try to tell you how you can recover lost data. For those interested, welcome to the cat.

It should be noted that if you mistakenly formatted the internal memory of your smartphone/tablet/smartpad, then you should not be upset, and most importantly, in no case should you write anything to the device’s memory, this way you will be able to recover more data.

The MTP protocol does not allow the computer to recognize the connected device as a USB drive and recovery programs cannot scan such a device and save the data, so we will need to copy the entire internal memory partition as a system image.

Preparing your Android device

You will need root and USB debugging enabled.

PC preparation

In order to copy the system partition, we need:

Drivers for your device (in case of problems);
ADB (adbdriver.com or developer.android.com);
FileZilla server.

First, install USB drivers for your device and ADB. After this, I advise you to restart your PC.

VHDtool

We create a folder with the address C:\cygwin64\000 (the name does not matter, just don’t use letters other than Latin), our image will be located here. Copy it to the VHDtool.exe folder.

FileZilla

During installation, we agree to all standard settings.
After installation, FileZilla will start automatically, but you need to exit the program and run it as Administrator.
When you start FileZilla it will ask for the server name, leave everything as it is.

Listen on those ports 40
timeout settings - the default is 120, 60, 60, and we set 0 everywhere and click OK.
Go to edit - users. In the users window, create a new user. In my case this is the qwer user.
Click Add - write the name - password pass - click OK.

Next, in the same Users menu, select the Shared folders tab on the left. We go there and add the folder into which our block will be uploaded. Click Add and add the folder C:\cygwin64\000. The path to this folder will appear in the window. If there is no letter H to the left of the inscription C:\cygwin64\000, then you need to click Set as home dir. Then, highlighting the line C:\cygwin64\000, you need to check the Read and Write rights. Then click OK.

A.D.B.

We will need the following files:

adb.exe
AdbWinApi.dll
adb-windows.exe
AdbWinUsbApi.dll
fastboot.exe

You can download them at.
Or extract the Android SDK from the distribution kit.

Copy them to the folder C:\cygwin64\bin

Checking ADB operation

We launch the console from the folder C:\cygwin64\bin; to do this, just enter cmd in the address bar of Explorer

Enter the command:

The list of connected devices should not be empty; if after the line List of devices attached is empty, then you have not installed USB drivers or have not enabled USB debugging.

When everything goes well, the console looks like this:

20352f2c – my Xiaomi Mi2s

USB modem mode

We will need to connect the device via USB to your PC and enable USB modem mode. I use CyanogenMod 11 and this mode is located at: Settings > Wireless networks > More... > Modem mode > USB modem

Screenshot

Now we need to find out what IPv4 address your computer received.
Using the ipconfig command on the command line
or
We follow the path: Control Panel\Network and Internet\Network and Sharing Center

Click on the inscription 'Local Area Connection', then Details and copy the IPv4 address.

In my case it is 192.168.42.79

Important! Each time you reconnect the USB cable and turn on/off the IPv4 modem mode will change.

What memory block do we need?

All the memory in your device is divided into logical blocks, we don’t need to download everything, just understand which section contains the erased information.

Now we need to look at the list of memory blocks, to do this we enter the following commands line by line:

Adb shell su find /dev/block/platform/ -name "mmc*" -exec fdisk -l () \; > /sdcard/list_of_partitions.txt
Hint: if you are too lazy to manually rewrite commands or are afraid of making a mistake, then you can use copying, but pasting a line into the console in the usual way will not work, so you need to right-click on the console window, then select Edit > Paste.

After which the file list_of_partitions.txt will appear in the internal memory, which we need to copy to the PC and study.
You can copy it to our 000 folder using a simple command (it should be executed in a separate command line window):
adb pull /sdcard/list_of_partitions.txt C:/cygwin64/000

My file looks like

Disk /dev/block/platform/msm_sdcc.1/mmcblk0p27: 25.6 GB, 25698483712 bytes 4 heads, 16 sectors/track, 784255 cylinders Units = cylinders of 64 * 512 = 32768 bytes Disk /dev/block/platform/msm_sdcc.1 /mmcblk0p27 doesn't contain a valid partition table Disk /dev/block/platform/msm_sdcc.1/mmcblk0p26: 3758 MB, 3758096384 bytes 4 heads, 16 sectors/track, 114688 cylinders Units = cylinders of 64 * 512 = 32768 bytes Disk /dev/block/platform/msm_sdcc.1/mmcblk0p26 doesn't contain a valid partition table Disk /dev/block/platform/msm_sdcc.1/mmcblk0p25: 402 MB, 402653184 bytes 4 heads, 16 sectors/track, 12288 cylinders Units = cylinders of 64 * 512 = 32768 bytes Disk /dev/block/platform/msm_sdcc.1/mmcblk0p25 doesn't contain a valid partition table etc...

The internal memory in my device is 32 GB. Therefore, I am looking for the largest partition, in my case it is mmcblk0p27 with a size of 25.6 GB, in yours it will most likely have a different name, or will not have a p** at all. Of course, no one guarantees that the largest partition will be the one on which just recently your photos, videos, documents, etc. were stored, but in 90% of cases this turns out to be exactly the memory partition that we need. Otherwise, you will have to copy all the images in order and check each of them.

Copy the memory partition to the PC.

If you have already closed the cmd window, then launch it again.

Enter the commands line by line:

Adb shell su mkfifo /cache/myfifo ftpput -v -u qwer -p pass -P 40 192.168.42.79 mmcblk0p27.raw /cache/myfifo
Don't forget to make appropriate adjustments to your code!

Let's decipher what is written:

Qwer – account name in FileZilla (you have your own if you changed it)
pass – password for your account in FileZilla (you have your own if you changed it)
40 – FileZilla server port
192.168.42.79 – FileZilla server address (you have your own)
mmcblk0p27.raw – memory block to be copied (you have your own)

Open a second command line window and enter the commands:

Adb shell su dd if=/dev/block/mmcblk0p27 of=/cache/myfifo

We look at the FileZilla window and see that the downloading of mmcblk0p27.raw to the C:\cygwin64\000 folder has begun, now you can close the cygwin windows and take a tea break.

Convert and restore

Are you back? Did you download the file? Great. Turn off the phone, connect the Internet. Launch Cygwin.bat and enter the following commands.

Cd C:/cygwin64/000/VhdTool.exe /convert mmcblk0p27.raw
Don't forget to correct mmcblk0p27 to your block number!

The conversion took me a couple of seconds. The output is the same mmcblk0p27.raw file in the C:\cygwin64\000 folder, but slightly different. This converted file can be mounted as a virtual disk, or, for example, through R-studio, data can be restored directly from our image. That's what I did.

Hint: important points are marked in yellow.

Results

My goal was to explain in popular language how to copy a system partition from an Android device to a PC. Perhaps some will blame me for the difficulties associated with a USB modem and ftp, and will say that it was probably easier to pull out the image. I’ll answer this: I tried other methods described on 4pda and xda-developers, it didn’t work out for me, but with ftp it worked on the second try, and when writing the article everything generally went like clockwork.

I was able to recover all the lost photos without loss of quality, and even those that I had not even thought of recovering. During the restoration, photographs were discovered that I took in August last year, when I just bought the phone and tested the camera.

If the system was in order, without any damage, then various main blocks or boot files may be read. We can say that this software scans or otherwise reads the media, looking for the first 10 files in all sectors of the mobile device, on the basis of which the size of the block or cluster at their location is calculated. That is, where they are. As soon as the size of the above-mentioned structures is determined, the program scans each block. All blocks are included in the "signature" database.

So, Photorec determines whether it is possible to recover deleted photos from a mobile device.

The developer of this application also says that it is able to recover about four hundred files of various types (that is, not just photos). The program can recover archive files (rar or zip), various videos, etc.

This is a prominent representative of “basket” applications. Here the developers decided to make them narrowly focused. That is, they created separate basket services for storing SMS, images, videos, etc.

Services that claim to recover all data from a phone often do not work as expected. They may request money to open content. It happens that they sell keys to expand such capabilities, but this function is either not fully developed, or is generally a scam.

Here the emphasis is placed on the motto: less, but better. There is only one condition for a more universal version of the application. It is indicated in the description: the presence of root rights, which is easy to obtain.

How to recover deleted data on an Android system

As we mentioned above, information recovery will be carried out using the 7-Data Android Recovery program, at the time of writing it was completely free, perhaps in the future the developer will introduce a certain fee, but let’s not talk about sad things for now :)

7-Data allows you to easily recover most deleted files both in internal memory and on an external SD card.

You can download the program from our server using this link.

Then we follow the standard procedure. Unpack the archive and run the 7data-recovery-suite application file. Following the installer's prompts, we perform a complete installation of the program on your personal computer or laptop.

After successful completion, open 7-Data Android Recovery:

Before starting the recovery, you need to enable USB debugging of the device and connect the smartphone to the computer using a USB cable, to do this:

1. Go to the settings of your smartphone – Developer options – USB debugging (check the box);

2. Connect the USB cable to the smartphone and then to the computer;

3. In the 7-Data Recovery window, click on the green “Next” button. A window with a list of memory cards should open in front of you, you need to select the one you need and click the “Next” button.

4. The device scanning window will appear. Here you just need to wait a little while the program completely scans the device and displays a list of files that can be returned.

5. Upon completion of the scan, a structured “tree” of folders and files of the device is displayed.

6. We go through the list and mark those that are subject to restoration. Click the “Save” button.

Important! The data you are recovering must be saved in a separate folder on your PC; do not save it to the memory card again. You use the program at your own peril and risk; it does not provide a full guarantee that everything will be restored efficiently.

As you can see, the procedure does not require deep knowledge, and even a beginner user will be able to recover most of the seemingly irretrievably lost files and data of their Android.
