Hello, I own Android 4.0 M975 tablet. Today, after a night of charging it, I disconnected the charger, and the screen showed blinking ANDROID logo as usually, but it remains frozen on this blinking logo and doesn't go ahead. Pressing power button - with or without the volume+ button -- did not switch it off. Nor resetting it with a tootpick. Somebody may help my with advise? (added after 5 min. break) Finally, I managed to switch it off by pressing with the tootpick especially hard into reset whole, but after new switch-on, the same Android logo freezes again. Question: Might it be caused by occasional over-charging? and if so, maybe after some days of leaving the device as is, it may return to normalcy?
