Dear all,
I have backup my f2fs android partition via netcat and adb.
After loosing the original partition, tried to restore it on a local
drive and access it via linux but i am encountering the following
issues:
A. trying the command
sudo mount -t f2fs /dev/sdc1 /mnt
gives the following error
F2FS-fs (sdc1): Failed to read root inode
B1. Tried to fsck the file system , see bellow:
sudo fsck.f2fs -a /dev/sdc1
result:

Trying to mount it , no success, gives

Any help or advice will be much appreciated.
Keep up the great work on f2fs.
