S805_MXQ_V03 unbrick

[gcsuri]

Hi,

I started this topic to find and share info about unbrick exactly this S805_MXQ_V03 20150816.
I have uploaded a wrong bootloader.
Only the red light on when power up the unit.

UART says:

QA5:A;SVN:B72;POC:3FF;STS:6B730000;BOOT:0;INIT:0;R EAD:0;CHECK:0;PASS:0;

Error loop 10times, error...

PUB init fail! Reset...

I have read the uboot and other source so I think the SDCARD unbrick method works when the bootloader can be run.
So I need the USB burn method...
I've downloaded the USB Burning software but I got DDR error at 4%, sometimes at 2%

Board has H27UCG8T2ETR nand chip. Some thread says I need to short the pins 29-30 the others says pins 17-18 none of them worked for me.

I need help to unbrick the device. Where can I find the proper image to this box?

best regards, gcsuri

Hi,

ok, I finally unbrick th e device. Needs:

USB burning tool 2.0.7 - http://yun.baidu.com/wap/link?uk=674...eid=1344739399
DDR img file - https://cloud.mail.ru/public/7oSn/WunL7sMWW
USB A-A cable

You don't need to push recovery button nor short the pins.

PUB init fail! Reset...

v2.0.6.2 works fine Win 10 x64




My MXq board is dated 20150816 and this image flashed successfully, however my full boot led is still a strobe, lol, a mixture of red and blue lights together which I think looks kind of cool, not as glary, anyway, its been like this since I originally unbricked it trying to install a custom Android rom a while back. Now onto flashing 6.0.1.1 again and see if I have any better luck.

May I get infected?
Thank you - I linked an other source.

I've tried this, but keep on getting an error (see screenshot). Tried it with USB_Burning_Tool_V2.0.6.2_built2 and with USB_Burning_Tool_V2.0.8, same result.
Any suggestions?
