Key driver not found... Booting OS
Android cardhu-user bootloader <1.00 e> released by 'US_epad-10.6.1.8-20130225" A03
Starting Fastboot USB download protocol.
Then I had the option to select RCK - Android - Wipe Data
When I selected RCK, it brings me to TWRP.
The boot animation has the word ANDROID flashing from left to right. It probably was a custom boot animation.
Please let me know if you need anything else.
