[Q] ANYONE KNOW HOW TO FIX E:failed to mount /efs (invalid argument)

Ok I have the Galaxy S4 T Mobile Version, I flashed a Kernel that wasn't for the phone accidentally and now im getting this Error E:failed to mount /efs (invalid argument)
Is there anyway of fixing this, Unfortunately i dont have an EFS backup, the phone does work on stock rom, but as soon as i try putting Cynogen Mod on it i get through the install but then im stuck on the boot image.
Ive looked up almost everything on the internet, but cant find anything
Please help me, your my only hope

What do you mean? I know how to flash TWRP. Flash the tar file through the AP section in odin? Can I flash it with the img file? Always did it with the tar file, never had this problem....I will check the TWRP installation guide again...
Thanks...
TWRP couldn't read my internal storage....what could have caused this? I have a lot of experience with bricked phones. I managed to flash the stock rom but yeah....I wanna flash a rom you know...

Thanks...will check this !

Bootloop after ota update, flashing stock through odin doesn't help.

Hey guys. I haven't rooted my SM-935F. Got some problems with it, while using it for a longer time without a pause, it lagged and then i had to restart it in recovery mode. In the night it wanted to update through ota, but bootlooped for some reason. I flashed already two different stock roms, but after both it displayed this error: "E:failed to mount /data (Invalid argument)
can’t mount ‘/data’ (Invalid argument)
E:failed to mount /data (Invalid argument)
E:Can’t mount /data/log/recovery_log". Still haven't find any solutions on the web. I'm afraid there's a hardware problem on this phone. However, do you have any ideas, what I could yet try?

That message is quite common in recovery, many people report having it, but they claim their mobile keeps working as it should.
I had it also after the Dec FW update, and then my S7 started to love bootlooping till the point I threw it now to Samsung for repair.
So, is this message your only problem or do you still get bootloops?

I got a message, that something might went wrong while updating, so i should repair the software via SmartSwitch, but i didn't help at all. When i turn it on it stops "installing update" at 32%. I guess, the only survey is to bring it back to Samsung for a repair, like you did.

Anyone know how to fix this error in twrp? I tried flashing a new kernel and it bootlooped. Now when I try to restore my backup I'm getting this error.
