I just got a Telechips TCC8902 and I connect it to my PC via USB and make sure USB Debugging is ON and still when I do Privacy -> Factory Reset - Reset the thing just powers off (not factory reset)! What is wrong??
My tablet has done that twice.. the first time I thought it was related to me repeatedly attempting to install clockwork recovery. But the 2nd time I don't recall any attempts on installing the clockwork recovery.
Anyway, the only way I could factory reset was to flash a firmware from the pc.
