I have finally recovered all of my data from my broken android smart phone, the only option i was left was to access the boot menu of my phone in the boot menu i backed up all of my data to sd card in the form of three files name userdata_xxxxxxxx_xxxxxx.backup 1 and 2. finally i found a solution how to extract the data from these files watch the video and subcribe bellow the detail information of these files and the commands used to extract data from these files. on ubuntu (linux) and windows operating system
There were no exact information about their format. Appeared, that it is single Linux Ext4 divided into several 2Gb blocks. Each block has 512 byte header unnecessary for us. Run unix dd unility (or dd.exe under Windows, or even bbcopy.exe) to reconstruct Ext4 image in single file. Do it on partition supporting large files above 2Gb (NTFS, Linux Ext4, FBSD UFS, etc.)
Commands used in the video
dd if=userdata_20100101_000617.backup skip=512 bs=128k iflag=nocache,skip_bytes oflag=nocache,append conv=notrunc of=img.ext4
dd if=userdata_20100101_000617.backup1 skip=512 bs=128k iflag=nocache,skip_bytes oflag=nocache,append conv=notrunc of=img.ext4
dd if=userdata_20100101_000617.backup2 skip=512 bs=128k iflag=nocache,skip_bytes oflag=nocache,append conv=notrunc of=img.ext4
for mounting using ext4 file use the following command /mnt/xam is for the directory
mount -t ext4 -o loop img.ext4 /mnt/
you can open the ext4 file in 7zip on windows operating system
