Title: Dual Boot Loader FAQ/Troubleshooting
Post by: JayRed on February 08, 2010, 10:32:33 am
Hi everyone, after seeing how much trouble some are having with the dual boot loader, and having searched for a few hours myself trying to find my solution, I decided to compile a list of all the known problems installing the dual boot loader and their discovered solutions.  Please post if you think of any I missed, and if you have a new problem, tell us all the info you can!  Hopefully we can help you find a solution.


I. I can't get my Dingoo into USB Mode!

II. The dual-boot installer gives an error
1.) Which Operating System are you using?  Windows XP has been known to be the most painless version of Windows to use for this process, but each OS has its own caveats.  Read below.


2.) Ensure you are in the correct directory

3.) Ensure you have copied the command line exactly if you have copied it from a guide.  Check your memory addresses.


III. The installer says its successful, but my Dingoo stays on a black screen!
Here we enter the realm of speculation.  There are various solutions to this problem that have been found.  I'll do my best to name them all.


***If you have any problems/solutions not addressed here, please post them, and happy Dingux'ing!***[/list]

you should change that to windows xp is easiest windows version to use, on linux you don't even have to check drivers, just run the tool and that's it

I had trouble with the screen staying black for ages, the solution that worked for me was:

when setting to usb mode, have your dingoo plugged into your computer already (the usb logo will show on the dingoo screen)
hold B and push the power switch, keep holding B for a while (so the dingoo turns itself back on cos its connected to usb), and it turns into usb mode.

thats the only method for turning on usb mode that worked for me.

I tried heaps of times setting it to usb mode THEN plugging into my computer as all the tutorials seemed to say.

so, if your having trouble with the screen stayind black, make sure you try setting it to usb mode AFTER plugging your dingo into your computer.

DemonXTC's solution worked for me (the POWER+B method, as opposed to the RESET+B method) -- thanks!

I am using firmware 1.2, if that may be of use to others when trying the various USB mode options.

Thanks for a great thread!

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.

Hi, I'm new to both Dingoo, the Dingoo community and Dingoonity, but here goes.

If you still don't get the flasher screen on your Dingoo (after executing the second line in the command shell) you might want to consider the fact that you might have to use both B+Reset and B+On/Off for it to work. I installed the Dual Boot Loader onto an A320-unit yesterday (ILI9331_3) and as it was my first Dingoo I followed the steps in the Idiot's Guide. After a few hours of fail I found a method that worked, I followed the guide EXACTLY until Step 2 under "Flash firmware". Instead of the instructions in Step 2 I reconnected the Dingoo to the PC before entering USB Boot Mode and I had to do that by using B+On/Off instead of B+Reset (although I had to use B+Reset earlier throughout the same guide, redid it all with only B+On/Off later on and then it didn't work).

Also, I did it from a PC running Windows 7 and did not remove/uninstall the original China Chip Drivers prior to installing the new ones from the Dual Boot folder. I'm not into flashing or hacking so I don't know if this could cause any future problems but I managed to install both the Dual Boot Loader, Dingux and GMENU2X so hopefully it should not corrupt later on because of that.
