ko nhận keyboard cũng đè ra clearme trời, clearme xong chắc chết luôn máy :D
Máy trước đó chạy bt, khách tắt máy update gì đó, qua em gỡ pin ra thì nó chạy, dùng phím bt, rồi sau đó ko kích được, thử phím khác vẫn y vậy, để tự kích thì kích lên nguồn chạy bt,

Disable onboard ram:
Thanks to the boardwiev and schematic available here, I found out how to shut down the onboard ram.
This configuration works, tested, I admit it's not professionally done, when soldering with hot air all 3 too small resistors flew away, I replaced them with a piece of wire and it works without a problem. Correctly, all 3 small resistors from the left side should be transferred to the right, to the positions where the piece of wire is now. I believe you will do better than me.
