Soft Bricked i337M. Maybe EFS problem.
I used TWRP to wipe all my partitions under advanced wipe.
I Odin'ed the stock kernel, stock rom and TWRP.
I used TWRP to mount the efs partition, and adb pushed my backed up efs.zip into that partition.
I checked using the TWRP file manager that the files and folders are all in the efs partition.
But after a reboot into TWRP, the efs partition would become empty again, as if I never transfered the files.
And off course, my phone is now stuck at the notorious Samsung logo boot loop.
So why did the files delete themselves after every boot? And is there any way to solve my boot-looping issues?
My current partition size:
EFS (4mb) it is empty, but still has 4mb?
