Here you go. Stock ROM kit.
Flash this just like my custom ROM.
This will revert to stock.
Remember, there is no stock ROM download from Arnova. This stock ROM was an ADB dump from a user! Thus I cannot confirm it is a real stock ROM but looking at it and the fact it works on the tablet, I have to assuem it is real.
Your on your own with this. I supplied it by request.
1) EraseIDB in the flash tool.
2) Check the loader box as you must revert to loader 2.06 to be truly stock.
