The battery is not hard wired.
There is no internal hard drive.
It can be reset even if bricked without taking the cover off.
(Pulling the battery out does nothing helpful.)
There is a 6mb initialization file that can be found online.
Copied to SD card and booted (with reset button) with card in slot will re-initialize to "green man".
While green man is present (stays on screen indefinitely) second file (firmware update, 158mb i think) is then booted (reset button) from seperate SD card.
Connect charger before the process.
There is sufficient voltage-regulation to allow charger to be connected/disconnected at ANY time during use.
I have done this fix after rooting and screwing with mine until it would not boot.
The firmware update should be done in any case as the original firmware was buggy.
A hard lesson but still a great tablet for the price.
Many are currently available on Ebay averaging $70.00
(of course this fix will not help a dead for-hardware-reasons tablet)
