I dropped the my dingoo on tile floor as i was running somewhere and this is what happened;
sdcard flew off to some random direction,
original firmware was playing an mp3 song off of the sdcard, it stopped playing
the screen stayed lit with the media player frozen.
"Oh well" I though while looking for a small screwdriver to hit the reset button.
reset didn't work. Screen was still showing media player in a frozen state (and lit)
I was baffled that reset didn't work. This means something very bad.
5 minutes later I was in front of a pc and plugged the frozen and brightly lit dingoo to usb port.
Nothing happened.
Windows didn't find any new device, even and "unknown" one.
dingoo was still showing frozen media player screen.
Time to open up the case, I opened up the case planning to disconnect and reconnect the battery as we do with frozen cellphones.
But this is at the end a cheap Chinese product, a connector for battery costs money, and due to cost saving there is no connector of battery and circuit board. So I cut the red wire that was soldered onto the main board and battery, and the dingoo was dark.
Then I reconnect the wires, nothing. I soldered them together. I hit reset button and the screen became white!
That's it, eternal whitescreen of death. After some inspection inside I realized that the battery had been stuck onto a tiny coil, and the coil had broken off the circuit board, probably due to shock of the drop.
Don't drop your dingoo, it's not recommended.
