S805_MXQ_V03 unbrick

S805_MXQ_V03 unbrick

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:

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?

ok, I finally unbrick th e device. Needs:

USB burning tool 2.0.7 - https://drive.google.com/file/d/0B9T...ew?usp=sharing
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.
