I can get back into TWRP 126.96.36.199, I attempt to restore a backup of a previously working state, I've tried to flash different roms, I always factory reset / wipe Dalvik Cache & Cache under advanced.
I can connect with adb too so I'm hopeful there's something that can be done.
I keep reading I need bootloader 4.2, this is what I currently have:
Android cardhU-user bootloader <1.00 e> released by "WW_epad-10.4.2.9-20120809" A03
But where do you get updated bootloaders? I can't find them anywhere.
