I do understand that the background of my problem because I delete efs folder and i don't have any backup of it.
If someone so kind to share the efs backup for p3100, I really thankful..
I had stuck with this almost 4 weeks. I know this problem can be solved, but it seem no one want to share their backup.
I promise I will modify the IMEI id number

[Q] [HELP] N8000 : E: failed to mount /efs (invalid argument)

Hi guys ,
I really appreciate all the help you could do to me ,
I have a problem , that I can't install any custom rom and the error i receive is "E: failed to mount /efs (invalid argument) "
So I tried to flash the stock rom via odin after downloading it from sammobile and it did flash it but it stuck on samsong logo
tried flashing TWRP and installing Cyanogen but with no luck , stuck on cyanogen logo
tried omnirom and Gnabo , and the same problem it stuck on the logo ,
and when i go to the mount section on the custom recovery , "efs" is not mounted and it shows 0mb size
tried CWM and same problem
tried using adb while in CWM but I can't get a shell , it says file not found when using"adb shell" command
I tried re-partitioning using a "pit" from a post (not 100% sure it is for the same region but is said for n8000) and it finished successfully but still with the same problem
any ideas ?
Take it to a service center.

Question How to fix Samsung note 5 (SM-N920C) (E: failed to mount / efs (invalid argument) error with FRP lock on.

Hi Please help! I recently tried to unroot my galaxy note 5 (SM-N920C) but got an FRP lock once the device restarted. After watching some tutorials I managed to bypass the FRP lock by flashing the stock firmware, but then started getting this error (NOT REGISTERD TO NETWORK) when I tried to make a call. Now after trying different solutions to fix the network issue my device can't boot past the Samsung logo and displays (E: failed to mount / efs (invalid argument) error in the recovery mode.
I have searched for solutions but most suggest I flash TWRP via odin but that can happen since the FRP lock
is back on and my device can't boot so I cant remove my account manually. If anyone knows how to fix
this please help.
You can use odin or any software and install stable rom. This can flash stock rom. You need partition information table. You can get it from same Samsung model using adb shell.
