Hello everyone.

Ok so I read a lot about the issue, solutions, and how this usually happens.

It's just I don't know how I got this. Was just using my phone like everytime and ran out of juice. So I recharged it, turned it on and got this error.

Just as good as it could be, I have no EFS folder backup at this moment.

Is there any way I can:

1) backup EFS at this point
2) run the steps to restore the system with generic EFS
3) restore EFS

Any other ideas on how could I mount the EFS that stills there?
Thanks in advance.

If not, then I guess I will send it to somente with a Samsung Tool-BOX to restore system and IMEI after creating a new EFS.

First flash a full stock rom, factory reset in recovery before first boot. This might enable your efs to be read again.

Your problem happened due to instant shutdown, which corrupted one or more partitions. Don't ever let the battery get near zero, the emmc chip is very easily broken.

If stock firmware fails then pay for a repair, make sure it fully works on 4.3 before you pay.

Sure mate, I'm downloading the latest stock firmware from sammobile. Will flash it trought odin and will report news soon.

Hope it comes back to life again.
