3. Then, install the Android SDK file on your computer from here > Copy the adb.exe, adb-windows.exe, AdbWinApi.dll, AdbWinUsbApi.dll and fastboot.exe files to the location path: C:\cygwin64\bin.

adb shell

su

find/dev/block/platform/-name 'mmc*'-exec fdisk-l{}\;>/sdcard/list_of_partitions.txt

Next, enter the following commands and copy the partitions on your phone to a safe location: adb pull/sdcard/list-of-partitions.txt C:/cygwin64/000 > Open this file and check the information about your lost data > Open a new command window and enter these strings:

adb shell

su

mkfifo/cache/myfifo

ftpput-v-u sally -p able -p40 192.168.42.79 mmcblk0p27.raw/cache/myfifo

(Notes: "sally" and "able" in above command are the username and password you create earlier for the new user. And the digits are the port number and the items after digits are the server address.)

After that, launch a new command window and type the following commands:

adb shell

su

dd if=/dev/block/mmcblk0p27 of=/cache/myfifo

Wait a while until the FileZilla copies your phone data to the folder "000".
