I have same problem, after a long period of working the module won't start again, it seems like no power arrives to A9G but 5V is applied

It's been a while since I last worked with the A9G dev board. At the time when I was, I figured out that most of the weird failures of the device disappeared when I switched to a more capable voltage regulator. I cannot remember the exact component that I used but I would suggest you try fiddling with the power supplied to the device first.
