We should be trying to contact the original maker of this tablet and try to get the latest rom from them. GM10 Someone has managed it before and we got the las version for it back in December. I've been trying to contact the same person but he isn't responding. He had a friend who knew chines and got the rom from the company but he didn't give me more details. I have been trying to contact them in English but no response till now. Maybe you folks can give it a try too, or have someone with some Chinese knowledge.
