I have a Samsung Galaxy Note II GT-N7100 that has an issue, no baseband info or IMEI.
So I tried to repair it. I found a tread about EFS restore/repair here in xda-developers and downloaded this software:
N7100_EFS_Backup_Restore_WIN.zip (Please see the attachment)
First, I created a back up named "efs_ORIGINAL.img".
And searched on all forums for helps. I got an "efs repair.img" from a forum through 4 shared website and did run Restore_EFS.bat.
After that my phone no longer boot to OS.
I tried to restore it with "Restore_EFS.bat" but it failed.
I tried to restore it with Samsung Kies software (Tools -> Firmware Upgrade and Initialization.). It said "emergency recovery of firmware completed but stuck on samsung logo. It looks like restored to factory settings excepts efs.
I also tried Odin to install the OS. It said "PASS" but it stuck on samsung logo. It looks like OS is installed excepts efs.
The ISSUE now is /efs is corrupt. The phone need to restore it.
I got to recovery menu (Vol up + Power + home buttons) and tried factory reset.
it said:
---Wiping Data---
Formatting /data...
E:failed to mount /efs (Invalid argument)
Formatting /cache...
Data wipe complete.
If I go to recovery menu. I can see these at the bottom:
E:failed to mount /efs (Invalid argument)
E:failed to mount /efs (Invalid argument)
# MANUAL CODE#
-- Appling Multi-CSC...
Applied the CSC-code : unknown
Successfully Multi-CSC.
Please help me to restore efs.
Can i use ADB to restore my backup efs.img ?
Thanks in advance!
