I had the same issue.

First of all follow this instruction:

I used terminal from TWRP.

Second update TWRP to latest version. 3.0.2-2 has problem with EFS backup.

i have 3.0.2-2 but when i try to backup with 3.0.3-2 it displays an error

edit, i tried your codes, and everythink works again, you re my savior, thank you sir!
