Bricked MK 809 III after Flashing crashed

[neochouva]

Hey Guys,

I have a big problem and spent the whole afternoon trying to solve it:

While trying to flash to the currend neomode ROM the pc decided to not like the flashing process and the app crashed. Not I seem to have a half rom on my stick. This renders the stick unusable.

If I plug it in to the TV the red light is lighting up, but that's it. Nothing happens on the screen. If I hold down the reset button and plug it into the PC it is again lighting up. But my PC is failing to recognize the stick with "Unknown USB Device (Failed to receive device description)" << Translated from a german errormessage, might be a bit different on an english system.

I then went through different Forums and tried the method of short circuiting the pins 8 and 9 of the Big chip on the back of the thing. The result was the same. I even tried both versions of that trick (use the DC Port for short circuiting it and then plug it back into the pc // short circuit while pluggin into the pc).

Does anyone have any further Ideas? I'm really sad that my nice weekend project turned out to be a desaster.

I would be grateful for any Idea.

Regards

Ulf

One Step further but still bricked

well well,

now I am one Step further. I was finally able to get the Stick regocnized Again by shorting the 8th and 9th pin of the nand (nand it is i believe). But both the Rockchip batch tool and the RKAndroid Tool perform a restart of the stick during the flashing process. Problem is, that the stick seems not to start into the desired mode. It just ends up being unrecognized. I am just not fast enough to short the two pins again. Before I manage to do that both Flash tools time out. I also tried to just press the Button on the board that is supposed to put it into the PC-Connection mode. Even though I have been fast enough it still didn't work.

So any cool tricks (besides soldering a switch onto the pins)?

Lookint at this video:http://www.youtube.com/watch?v=4dlQkaDcgSY
It seems there are contacts on the Board supposed to do some magic for you. But that's an older model. The only contacts I see are labeled "R T G" Any Idea what that is? Or any tip for magic contacts on the board.

I Swear I have googled 'till my fingers bled. So it would be very nice to hear from anyone.

I had The Same Problem

The same thing happened to me. What I had to do was short pins 8 and 9 throught out the whole flashing process. I kept them shorted until everything was flashed. It took a couple tries. When it did finally work it flashe back to an older rom that was in the recovery.img I believe. When it booted into a working rom I flashed the rom I wanted and it worked.
I hope this helps.

hi,

i too bricked my device in the same manner.

first i flashed neomod 1.7 with androidtool which worked but "reseted" the hdmi connection like every 3 seconds (the rom worked though, was some kind of display problem). then i tried to flash 1.9a where an error occured (somewhere in the middle of copying the files during the flashing process). from then on it was idb fail all over.

i even managed to get into maskrom mode by shortcutting the pins. i tried every hints i found until now, 3 in the morning... but even in maskrom mode with rkbatchtool i couldn't flash due to "preparing of idb failed".

here's some of the logs from android tool:

i don't know any further since i am a newb. but i don't wanna let those 50 euros go to waste. y'all got any more of them... hints for me? i'd appreciate it. i got windows, linux, soldering iron what could possibly help.

Try with 1.6 tool instead of 1.7 as that worked once for me (no fricking reason why but it did)
