Frank_fjs:
Thanks! This post helped me heaps.

Nothing suggested here worked for me. Turned Udisk protection off, put it in usb mode with the power switch and B instead of reset-B, ran the second command a couple times in a row, unplugged the USB cable... screen stays black, and once reset, the Dingoo runs fine, just no dual boot option. Dismayed. Here is my post on the subject in another forum:

OK, I've been trying to flash my Dingoo to put Dingux on it. I've got the Dingoo in USB mode, have the right drivers installed, tried it on Mac and PC, and I get the same results.

That's as far as I get. The Dingoo screen never shows the flash script running - stays black. The Dingoo itself is unharmed - boots up just fine. I got this one from ThinkGeek. Perhaps they now have the thing write protected? Anyone else run into this?

I've run into that. Sometimes it just doesn't go, for no noticable reason. If you've tried it a dozen times, try it a dozen and one. Suddenly it will work fine without any explanation.

There's nothing 'write protected', what is happening is the tool is loading data into the Dingoo's SDRAM then executing it. The first step initializes the hardware and the second one is the installer kernel. For whatever reason, the 'go' command is not being accepted by the Dingoo, so after you load the code, it fails to execute.

But like I said, I've had the same thing; tried it on mac, windows, linux, and nothing worked. Finally I gave up, then tried it again 15 minutes later and it worked.

Same thing happened to me. Got it on the 3rd try. Keep repeating the procedure, it will stick eventually.

I've tried it now dozens of times, and no joy. I've pretty much given up on it at this point.
