I followed the guides to a T, the new drivers are recognised and I enter the commands which appear to run successfully, but the dingoo screen stays blank, and this is on XP on two different computers.
Maybe I am not uninstalling the china chip drivers fully? Two set of drivers initially show up, I delete one set and I am prompted to restart the computer, should I restart? How can I permanently uninstall them?
I'd really appreciate some help, I have read other posts about people having and overcoming this problem, could anyone offer some advice?
Don't re-start the compy. Nothing in any directions tells you to do that. If you DO follow the directions correctly, you will permanently uninstall them, because you will re-install the new drivers as part of the process.
What you are looking to uninstall is called "Jz something" in your hardware list. It's like 4 digits after the Jz. Uninstall it. THEN...reset Dingoo power and hold down B to put it in Rockbox mode, the Dingoo screen will stay black, but the power IS on. Do this while staying hooked up to the USB line.
THEN....install your new drivers from the pack you downloaded...do it manually. You should not have problems if you do it exactly like that.
If you re-start compy, it will try to automatically re-install the China chips...and also, if you unhook from USB...when you re-hook, it will try to automatically re-install China Chips for you.
That is why you do not re-start...or unhook from USB....until you have the new drivers - the ones in the pack you downloaded - installed.
Once they are installed, you're ok.
Incidentally, the china Chips are still available and on your Dingoo...they just are there now as a backup or alternate driver, if your compy ever asks to install them, don't.
I believe everything I said here to be correct, please, anyone, if I mis-stated anything, please feel free to correct, as I, too, am rather new at all this...but this is my understanding of how it works.
