[Galaxy Note II General] likepeas:
Got myself into a bit of a bubble, right now I'm holding onto a N7105 which is able to go into both recovery and download mode, I have flashed it with stock rom hoping it would restore itself but that hasn't been successful.

So what did I do to get my phone so screwed up, well I happily went to flash, super wipe before flashing the omega v6.1 without knowing that N7100 roms do not work on a N7105. While flashing the rom I did back up my efs which is currently saved as EFS.tar.gz, only after flashing the rom did I realize what mess I got myself into, but before realizing that, I reflashed the omega rom a few more times until it didn't even boot up and was stuck at the boot logo of the big android robot walking, only then did I realize something must be wrong.

So after a quick google search and a few downloads, I downloaded ODIN and the stock rom for the phone, flashed it everything went successfully, except that I get stuck at the samsung logo every single time. Yes I have tried flashing root and cwm, clearing data,cache,dalvik and then reflashing to stock rom again, clearing data and cache on that. It just keeps getting stuck at the samsung logo. I have tried flashing those n7100 roms again to see if it were to boot up, nope didnt work. So right now all I got installed is the stock rom and a cwm. ADB from my com to the phone works fine.

Going into stock recovery mode shows up this error :

-- Appling Multi-CSC...

E:failed to mount /efs (Invalid argument)

E:multi_csc:Can't mount /efs

Multi-csc applied failed.

and in my download mode :

Custom Binary download : 15

Current Binary : samsung official

System Status : custom

heres a recovery.log from TWRP.

my EFS backup was made in aroma installer and it's a tar.gz file, if there is anyway to restore that let me know.

I highly doubt any samsung repair centre will take that in with that many flashes. Really don't know what to do right now. Any help from anyone would be appreciated.
