Hi there,
First of all, I just want to say this is a great website. I've got a lot of help in setting up my Dingoo just by looking at these forums.
Now to my current problem - I have a Dingoo A330 with the standard system setup. All I've done is download some ROMS and emulators that work on the native system (eg, Master System, PC Engine, Game Gear etc)
Last night I was charging my Dingoo and thought I would just knock another level or two off Kirby's Nightmare in Dreamland

Anyway, I played it for about 15 minutes while the charger was plugged into the power socket and then put it down for a few minutes. I didn't seem to have any issues at the time, but now I am having a few problems:
- The main problem is that when I turn on the Dingoo, it gets stuck at the very first screen (the 'Dingoo Technologies' logo). I don't get any further than that.
- Second issue is that none of my PCs seem to recognise the Dingoo when I connect it via USB. When I go into devices, I can see it there, but it doesn't show up as a drive and there's no way to access the folders. Initially it said the device had malfunctioned, but I don't even get that message anymore.
- The third issue is that while it is on (stuck on the opening screen), I can't turn it off using the usual power button on the side. I can only turn it off by using the reset button, which actually resets it and I end up with the same problem.
Prior to this I haven't really had any problems. I've had a few issues here and there with ejecting from USB ports etc but nothing too bad.
In terms of solutions, I've tried downloading the driver to my computer so that the Dingoo is recognised but haven't been able to achieve that so far, through a combination of me being wary of shifty download websites and me being unable to use the drivers once downloaded.
I've also tried the 'hold B then reset followed by insert USB cable' strategy which I've read about in a few places. This usually results in my PC making a chime sound but nothing actually happening. The Dingoo screen turns black and it basically looks like it has turned off.
Any help would be appreciated.
