Glad the first bit worked, let's see if we can work this out, try getting in to recovery, once there, you could try flashing straight over with the ROMThank you for your help. Following your directions made my tablet work perfectly. I did something stupid though ( I locked oem) and now I am in bootloop , blocked by frp.
So I guess my only solution is to go back to stock, unless somebody has any other suggestions. The only thing I was trying was to get rid of the yellow kernel warranty warning at the beginning....
If that doesn't work, try loading a firmware through odin.
If it boots with either see if you can select the unlock oem switch to unlock.
Otherwise is back to stock and start again.
Good luck
