I just attempted to flash custom firmware to my dingoo, on the computer, everything worked fine, but as i was flashing, the tutorial said that i should see the "firmware update" screen on my dingoo. instead, i got a gray screen with many vertical, miscolored, lines in it and nothing else. after the flashing was finished, i still have this screen. and i can not do anything with my dingoo, obviously. i tried reflashing, but it didn't work. what do i do now, i just got this, and love it. please tell me it isn't broken. thank you.
