What can It be?
how can I recover to a full original firmware (again I've not rooted my tablet!)
thanks for any help
Check out this thread:
My suggestion is to flash the latest firmware for your tablet, get it from Sammobile, make sure it's for the correct model (SM-P905) unless you have a Verizon SM-P905V. If you have one from Verizon, do not flash or root, you will brick it.
If your tablet is not a Verizon model, then you can flash using Odin 3.07. You might as well root it and flash every available firmware update via Odin instead of waiting for OTA. I use Wanam Exposed to change my wifi tablet to Official instead of Custom after root.
