I have my tablet open right now to look at the headphone jack. I noticed that it is different from pictures I had seen of another one. May explain why there are different procedures for recovery, why some people say the g sensor works, and why some people have a headphone jack that works right. Here are some pics of both. Notice the extra button switches on the main board, and the blue daughter board between the lcd and the main board. Top two pictures are from the other one I saw. Bottom two pictures are mine.
