My GT-N8000 suddenly shut down, which wouldn't have been that strange if not for the fact that it did so without the usual "shutting down" message. I plugged it in the charger and was greeted on boot by the message "encryption failed, please perform a factory reset" (actual message : "echec du chiffrage"). I have no root nor cfw (I planned on waiting until the end of the warranty, that is next month). I also didn't update to kitkat so the only reason I can see to this problem would be the tablet having shut down improperly as it was low on battery.
I already tried rebooting several times with and without the sd and sim, to no avail, so it seems I will have to reset. Recovery says /data cannot be mounted, so i was wondering if it affected the internal sd and if there was a way to recover the data on it or is it definitely lost ?
I have attached the recovery below. Thank you for your help.
 although I wasn't counting much on it working, I tried to update to Kitkat trough Odin3 just in case. The only change is that now i've got a prettier error message (and startup sound).
