I was able to install xposed and super su, I made the mistake of installing the last available update that I seen, to which it has all kinds of bugs. It freezes and then you have to put the screen to sleep and awaken it. If you just leave the tablet on and allow it to go to sleep, the battery drains until completely dead. Is there any other chinese tablet with similar specs that we could use to port or start a official rom?

And thanks for the response :)
