I have the HK Dingoo A320. And the firmware refused to flash when I tried to put in custom using the d-pad method.
So being the idiot that I am, I tried using the Unbricker tool to flash my Dingoo with winXP and the Dingoonity 1.2a firmware.
The program became unresponsive during the process, and I pulled out my Dingoo to find that it was stuck on the first "paw" screen.
While it was flashing before that, the entire Firmware Update screen was flipped horizontally.
Now, I tried desperately to Unbrick it, and used the original 1.2 firmware, letting it sit for a long while. This time it worked and the Dingoo turned on like normal.
But every single screen is now horizontally flipped.
How do I fix this?
