Good afternoon am a new to the area of Android. Recently I bought an Android Tablet PC-aPad-MID - Wifi -7 "TFT Touch Screen - Rockchips RK2808 Processor-600MHZ - 2G-ARM 11 (SMQ5453). The device contains a means android 1.5. For my bad luck, I have a friend, he told me, i can update my android 1.5 to 2.1. The upgrade does not work and now my apad cant open it. Can you tell me how to put the old version (android 1.5)? Least how can do to work on my apad???
