I have tried the software reset button press and rotation lock method without any luck. it just says Erasing Userdata.. Erasing cache... blacks out and reboots back into the bootloop.
I have tried the update.zip methods with the three remaining roms I could find on the stock firmware forum but every time I try each one, it just loads with the red exclamation with the android laying down.
Was going to try flashing the EUU one, but I can't seem to get my CPUID as blackthunders A500 manager needs to have USB debug on, which I don't think was set before the tablet went bad. Just wanted to see what my options are as I am feeling a bit stuck right now. I have been searching the forum pretty tirelessly, but it is getting hard to figure what choices I have left. Any help would be much appreciated.
