How to recover the files deleted by Android phone?

Once you find that the data has been deleted by mistake, you must be prepared before recovery: never read or write to the storage medium again, because any redundant operation may overwrite the original storage area, and once it is overwritten, it will be more difficult to recover.

That is to say, the files recovered by software can no longer be used, and more professional equipment or software is needed for further recovery, which is only partial recovery. So, remember this!

Seeing this, you must know something about data recovery. Get to the point: how to restore the built-in storage of mobile phone (SD card reader is recommended to connect with computer to restore).

First, you need:

1. An Android phone with root permission (such as myself, it's Note 2 single card version N7 100, HTCNew One telecom dual card version 802D).

2. busybox has been installed (note: it must be installed in the /system/bin directory instead of /system/xbin, and you can use "Busybox Pro" to install it).

3. The necessary drivers have been installed on your computer.

4. Download the recovery tool "Recovery Tool.rar". (The download address is at the end)

5. Download "Recuva". This software is used to recover your data. You can also use your favorite data recovery software, but I still recommend Recuva. (The download address is at the end).

Operating Steps: (Take N7 100 as an example for the following operations)

1. Open the "Settings" of the mobile phone-> "Developer Options", turn on "Stay awake" and "USB debugging".

2. Connect your mobile phone to the computer and install the driver.

3. Decompress the downloaded "Recovery Tool. rar" to "C:\" (after decompression, you will find "AB" and "Cygwin" folders. )

Note: Please make sure that your C drive has enough space, at least the same size as the built-in storage space of the mobile phone. My version of 16G, N7 100, is about10.6g. If there is not enough space on drive C, I can decompress it and move the "Cygwin" folder to another drive. Just change the relevant "c:" in the later tutorial to the corresponding one.

4. enter the start menu "all programs"->; "attachment", run the "command prompt" as an administrator, (directly click "start" under XP-- >; "Run", enter "CMD" and press enter).

5. Enter "cd c:\ab" in the command prompt window that opens, and then press Enter.

6. Enter "adb Device" and press Enter.

* * Make sure to echo a string of numbers (that is, the IMEI number of your mobile phone) under the device list.

7. Enter "adb Shell", then enter "mount" and press Enter.

Note: The next thing is more important. The command just entered will give a long list, in which you need to find "dev/block/mmcblkopxx"/data/data (or user data) ". XX can be any number. In N7 100 and N7 105, "mmcblk0p 16" is a data partition. The last two numbers will be different for different devices, just pay attention to the partition name "/data". For example, my N7 100 is "mmbclk0p16" and my 802d is "mmcblk0p40".

8. Close the command line window. Turn on my computer-> " C:\ "-& gt； " Cygwin "->； Run "Cygwin.bat" to open "Cygwin Terminal".

9. Enter "export path ="/cygdrive/c/ab ":$ path" and press Enter.

10. Enter "adb forward tcp:5555 tcp:5555" and press Enter.

1 1. Enter "adb shell" and press Enter.

12. Enter "su" and press enter, and a permission request will be prompted on the mobile phone.

13. authorize "super user" permission request to ADB shell on mobile phone ("[MD: content] rdquo; Will become "#").

14. Then enter "/system/bin/busybox NC-l-p5555-e/system/bin/busybox DD if =/dev/block/mmcblk0p16" after "#" and press enter.

15. Minimize this Cygwin window and open another Cygwin terminal: My Computer->; " C:\ "-& gt； " Cygwin "->； Run "Cygwin.bat".

16. Enter "export path ="/cygdrive/c/ab ":$ path" and press Enter.

17. Enter "adb forward tcp:5555 tcp:5555" and press Enter.

18. Enter "cd /aa" and press Enter.

19. Enter "NC127.0.0.15555 | PV-i0.5 >; Mmcblk0p 16.raw "input.

20. Let the command run now, which will take a long time. It took me nearly half an hour to finish it by myself.

2 1. enter the start menu "all programs"->; "attachment", run the "command prompt" as an administrator, (directly click "start" under XP-- >; "Run", enter "CMD" and press enter).

22. enter "cd c:\cygwin\aa" and press enter.

23. enter "vhdtool.exe/convertmmbclk0p16.raw" and press enter.

24. Now close all command line windows and right-click "My Computer->" on the desktop; "management"

25. in the open window, select "save"->; "Disk management".

26. Select "Operation"-> in the menu; "Attach VHD"

27. enter "c: \ cygwin \ aa \ mmcblk0p16.raw" in the location field, and click "ok".

28. After loading, the disk space displayed on the right is "Unallocated". Right-click the disk name on the left (for example, my name is Disk 3) and select Initialize Disk.

29. Select the GPT (GUID partition table) check box in the Initialize Disk window, and then click OK.

30. Right-click the disk space that shows "Unallocated" and select "New Simple Volume".

3 1. Click Next in the wizard that opens. Each option uses the default settings, select a drive letter for the disk (for example, I selected "n"), and then click Next. Make sure that the Do not format this volume check box is selected here, and then click Next and Finish.

32. At this time, a window will pop up asking whether it is formatted. At this point, select Cancel to not format.

Right-click the new RAW partition and Format, make sure that the file system format you selected is FAT32, set the allocation unit size to Default, and make sure that the Execute quick format check box is selected. You certainly don't want to fill the volume with "0", which will damage your data. "quick format" means that it will only try to delete the index of this volume and create a new index. If this check box is not selected, the Windows operating system will fill the entire partition with "0", thus damaging your data. Finally, click OK.

34. A pop-up window will appear asking "Formatting this volume will erase all data on it". If you are not sure whether "Execute quick format" was selected before, please cancel and confirm again, and then select "OK".

35. Open the Piriform Recuva program, click "Next" in the wizard, select "All files", then click "Next", select "In a specific location", enter "N:\" or click "Browse" to select N disk, and then click "Next" to select "Enable deep scanning".

This procedure may take a long time to complete the "deep scan".

37. Once the program has finished scanning, you can select the file to be restored through the check box, then click "Restore ..." and select the location of the file to be restored, and finally "OK".

38. Wait for the file you selected to be restored. If some files can't be opened after recovery, it means that some data has been overwritten or lost and needs further repair. The process is complicated, so I won't provide it here.
