Hi you,
Did you solved the problem of your Onda V811? Show me the solution, pls! I flashed firmware v3.12 for V811 V8 to my V811 V1 and now doesn't work and I can't do anything.

sure, the only thing you have to locate correct "TF pins" to get device in World cup mode. In V811 different variants have different "TF pins" Location

I also have the same problem as yours. The tablet I have is already dead boot.
