I have similar (?) problem.
After flashing Dingoo Memory and install toddler pack 0.31 everything was ok. Dingux was running, every applications were working
But, in every case, when any emulators, games, etc hang up, after reseting Dingoo i have only Dingux screen, but system doesn't want to load. I see only black screen.
If i close Dingoo correctly (in Dingux panel), evevrything is ok. After reseting Dingux crashes. And I have to copy all files again.
What can i do to solve this problem?
