I had put the tablet into root for the remote play app (which is great by the way) once i had it up and running i wanted to see if i unrooted the tablet if the remote play would work. At that time after checking unroot on SU i had restarted the Tablet. Now it goes into Odin Mode and UDC Start. I know somewhere i had to have done something wrong somewhere. Are there any suggestions. Im also having issues finding the stock firmware for this particular tablet. When I try flashing the tablet i get stuck in random places like on aboot.mbn or it will fail or it wont finish initializing. If someone could help it would be greatly appriciated.
