@LobsterDarts Yeah, I have bricked two TB-X606's trying to downgrade (both have working, but broken screens, so no loss). Have recovered one, but I wouldn't advise this port as it is too easy to brick the device.... If you want a good UT experience with a tablet that is not expensive get a TB-X306F or TB-X306X and get the 4Gb/64Gb version. There are issues, but that is like all the UT devices, they have their quirks!
