Thank you guys!
I tried to flash an Android ROM last night, but I failed. I downloaded the sd card formatter and formatted my sd card, no luck. I got a black screen with blue words when I installing recovery. I want to stick my HD mini on the wall and turn it to a weather monitor device, but I don't want to push on/off button and wake up the screen each time. Is it possible to wake up screen by tape the screen or by automatically each time there is a light change? I knew some android apps can do it, but I have problem install android.
