Stuck on samsung screen and failed to mount /efs, /cache system... topic

Hello,

I have a galaxy note 2.

I am currently having big issues :

1. The phone get stuck on samsung galaxy note 2 screen


2. When I press Start / volume Up and Home, i get to this recovery mode where it says that /efs canno't be mount, same with /cache and /system (if i remember)
   E: failed to mount /efs (Invalid argument)
   E: failed to mount /efs (Invalid argument)
   
   #MANUAL MODE #
   --Applying Multi-CSC...
   Applied the CSC-code: unknown
   Successfully applied multi-CSC
   


3. I tried wipe / reset to factory option but it not working

For the historic, what I did on this phone :
1. I rooted it with odin CF-Auto-Root-t03g-t03gxx-gtn7100.tar.md5
2. Everything was fine during 1 year, then i had issue (phone crashing, settings reseting to default), so i decided to update the rom with the official one N7100XXUFND3_N7100OXAFND3_N7100XXUFND3_HOME.tar.md 5
3. Since yesterday night the phone is stuck on home

I still have a backup of the EFS, i read that i should restore the EFS but I can't do it with ADB because when i type root shell in adb it says : "error : device not found" (I am in download mode though)

Thank you for your help :)
