Sorry for being so loud with this, but I suppose other people might have similar problems.
If you're about to buy a dingoo straight from HK (DX for example) wait before you flash it with anything!

Read this topic: http://boards.dingoonity.org/dingoo-general/screen-'interlacing'-after-flashing/msg17585/#msg17585,
especially this post: http://boards.dingoonity.org/dingoo-general/screen-'interlacing'-after-flashing/msg18115/#msg18115

There is a high probability that newer dingoos come with different LCD model and flashing them with old bootcodes will cause number of display abnormalities. Dump your init data, the procedure is here: http://www.dingux.com/2009/05/new-a320-hardware-spotted-different-lcd.html and post it here first so I can prepare a new bootcode.

Oh and the dingux will also need modifications...

It seems that the new LCD comes with new controller: ILI9328 (or maybe it is 9325 but with different values in the init sequence, no way to check it now). So check your brand new dingoos if you haven't done that already.

I dumped my mine (but after the flashing) so it was pointless. If you do everything according to the instructions and don't write random commands on the console it will be fine. The 2k dump is enough - oh and it takes a while (few minutes [a lot of hex numbers scrolls across the screen during that time]) for the dump to complete.

But if you're afraid don't do it, cause I don't take any responsibility. What firmware version yours came with? And where did you buy it from?


PS The command nreadraw only reads and doesn't write anything so it should be safe. I'm not sure what will happen if you forget to type exit at the end (i suppose it won't flush the dump to the disk or something).

Well I havent flashed my dingoo at all yet, so I will dump tommorow when I wake up 

You flashed it with the 325 lcd? 331 is what the dingoos are shipping with nowadays.

My dingoo shipped recently with 325 (or 328 maybe?), so it's not true. And it's certainly brand new model, I'll post the photos of the internals for you to see. Anybody seen the JZ chip branded "DINGOOGAME"?

That would explain the problem as well. User the unbricking tool and flash the correct firmware

The guy says that he's got washed colors and "interlacing" problem. If he had used 9325 instead of 9331 he would've mirrored display or garbage on the screen. Trust me, I deciphered most of the lcd register settings that differ between those two .DL files.

I attach my breakdown of the register differences and my hacked .DL file (I zipped it because this gives you a basic CRC check).

@nikunjgoyal10 Flash your dingoo dingoo with this .DL, it should fix the problem. If not, in worst case you will have garbage on the screen (I doubt it) and will need to flash again with different .DL. Remember that if you choose a modified firmware with changeable themes like 1.20-pof you need to put the system folder on the dingoo first. HTH

DISCLAIMER: Of course, I take no responsibility for any damages caused by using this stuff. It should be safe though. I flashed my dingoo like tens of times before coming up with this solution. Bricked it a few times in the process and unbricked. I even plugged the usb out during the upgrade;). It appears that dingoo is nearly impossible to brick permanently.

The forum doesn't allow to attach zip files - so here it is: http://byteboy.x25.pl/dingoo/ILI9325_PINKEEN_HACK.ZIP

Whats the difference between the 325 and the 331 is one better than the other?

I'm no expert in this stuff, but basically they're used to drive different lcds, but I'm sure there are lcd's that could be driven by both. I didn't study the datasheet for capabilities, but they don't differ much. What matters is the lcd screen (viewing angles, contrast ratio, etc.) and those, from what I hear around here are similar in all dingoos. So no, It doesn't really matter which one you have, you shouldn't see any difference.

Is it a good timing to buy a Dingoo A320 today ?

I'd say that even if nothing more was ever released for the A320 it would still be worth the money. That though is from a "using it for fun" point of view not a "developing for it" point of view.
