MX III s812 amlogic 2g ram/8g ROM, not boot, only red light

[Busty290]

Hi guys. I have just joined this forum nice,
I hope you solve my problem.
I have a TV Box android MX iii with amlogic s812,
This BOX, remains with the red light.
I downloaded the new firmware, and used usb burning tool, but arrived at 2%
fails and exits written Romcode/Initialize initialize USB DDR/Read status/Control setup error.

I tried with boot card maker, formatted the SD CARD, put the files in the stock firmware,
reset using the toothpick and switched power, but remains steady red.
what to do?
Thank you

I tried boot card maker, but the box stays with the led solid red, zero
results. Now I want to try with USB burning tool, but I don't know if I should
use a USB cable male to male, or if I can use
USB OTG connection BOX.
I don't even know which pins of the nand flash solder to get the result.

If you can help all right, otherwise this box I throw it in the trash.
I am tired.
Thanks always.

Yes that was the post pins to short (not soder) are listed in post 13 shows you what pins. If you check near chip it will have a dot at first or star of nand. One is beside the dot.

Hello. My Nand flash is FORESEE NCEFES78-g.
You can look at the picture above and tell where should start counting the PIN? From left or right?
Thank you
