    I have a Samsung galaxy tab 2.One day as I decided to wipe everything,i noticed a message in the recovery mode saying unable to mount efs.I cant open my tablet or anything.After looking on the internet,people were telling me to flash a custom recovery like CWM.In order to do that I need to root my tablet.To root my tablet I need to enable USB debugging,which I can't because I can't access it.Can you help me please?

    Can you get into download mode?
    To flash either the stock firmware or a custom recovery with Odin, USB debugging does not have to be enabled.
    What is your complete model number?

    The model number appears to be GT-P3113.Is flashing a stock firmware all I have to do?I already flashed TWRP.Having some trouble rooting it with SuperSu,as whenever I type SU in the terminal,it always says SU not found.Thank you.

    This should be the stock firmware.

    Does your model have a SD card? If so, copy the SuperSU update zip file to it or internal storage then flash/ install with TWRP.

    If flashing the stock firmware doesn't fix the EFS issue, motherboard might be borked.

    Problems with EFS usually results from corrupt modem/Baseband and if no problems with motherboard, flashing stock firmware should fix it.
