i have a android phone that is now with boot loop problem, i try under linux to backup userdata partition with adb pull ... command being in recovery mode.
but i'm unable to read the file generated, it is not recognized as a f2fs file system image.
Mount -o loop -t f2fs does not work wi th error : wrong file system type, wrong option, wrong superblock on /dev/loop38, missing code page or auxiliary program, or other error.
i want to avoid to risk to loose all my data .
I don't have enough space on the phone to do the backup and OTG does not seem to work.
