Funny thing is i really did my homework on this one and still could not figure it out. I had windows 7 show extensions for all known file types. I downloaded the hp usb-tool and formatted the sd card with it. then i got JKdefrag and defragged the sd card so the files would be read in the right order. All that info i picked up in the forums and i was trying hard to figure the problem out for myself. Sometimes i think i just try to hard and wind up screwing up on the little stuff.  I just needed a clear head this time out. Thanks again.

For electrozone and other people having trouble accessing files on the NAND, Ayla has prepared a special kernel and script to make a dump of the first few blocks of the NAND. Such a NAND dump can help us diagnose the problem and hopefully come up with a fix in a future OpenDingux version.

You can download the required files here: http://marvin.crapouillou.net/~paul/nandtest.tar.gz

Inside the archive you will find three kernels, one for each ILI model. Pick the one for your Dingoo and put it on the SD card named just "zImage". Then take the "frontend_start" script and put it on the SD card in the directory "local/sbin". This directory will exist if you have booted OpenDingux at least once from that SD card.

Make sure the USB cable is unplugged and then power up your DIngoo. It will boot, dump the relevant blocks of the NAND, copy those to the SD card and then power off. Take out the SD card, put it in your PC and upload the new nanddump.tar.gz file somewhere where Ayla and I can access it. Then remove the "frontend_start" script and restore your original kernel (zImage).

That's nanddump.tar.gz

@electrozone: Thanks for the NAND dump.

The bad block table seem to be in erase block 5 on your Dingoo, instead of erase block 4 where most Dingoos have it. Usually, block 5 is the first block of the read-only part of the native OS (Z:), I don't know if that area is moved on your Dingoo or whether it is smaller.

What is very strange, is the contents of erase block 1-2 (mtd1.img). It looks like the native OS loader, but only 128-byte fragments of it, where one would expect 2048-byte fragments. So there are big gaps in the loader code. Does the native OS even boot on your Dingoo?

Which ILI are you using? Knowing that would save time not building 3 different kernels when we want to do more tests.
