Hi friends,
Does anyone know what pins I need to short to revive my board? It's an IntBox i7 and it has the Samsung KLM8G2FE3B chip.
Any help is appreciated because I'm about to throw it to the garbage

That's the image of the board. It's a MXQ9 5G, but the board is the All Winner H3 V3. Tried to flash, usb recognizes, the flash starts, but fails.

Here's the image:

MX Q Pro 4k with the Roku3229 (2GB RAM 8GB storage) and NAND NW814 as you can see on the pictures bellow. I got this tv box with logo standing in forever loop. Somehow I managed to connect it through RK Batch Tool and flash it with working ROM that was to heavy for this board, gpu... This is a Chinese manufacturer with no Support, so I am on my own.
As it was to heavy, video was lagging but everything worked. I tried to use another ROM. Unfortunately I got the red error, through RK Batch Tool. No chance to boot no more, no chance of connecting it via usb. I looked for the pins to enter a MASK ROM... No luck so far... Any advice?

Hello All,

I have a Sencor SMP 5004 pro s905 android box and i would like to upload a custom rom, but the USB Burning tool is not recognizing at all.
I have tried to push the recovery button, but did not work.
Most probably need to short some pins, but couldn't figure out which ones.
Some have any ideas?

X96 MAQ5x3_141 V4.1 20112 new revision(!) ?

Possible short pin location / area, i am guessing !!?

[soldiaz]

Anyone here can identify X96 MAQ5x3_141 V4.1 20112 new revision(!) ?

Revision 3.1 pins do not exist on this board, already scratched off slightly the surface to get to the copper lines.....no luck ...maybe I am supposed to sctratch off more - hope anyone knows

EMMC is hynix H26M52103FMR, https://www.elnec.com/en/device/SK+H...%5BFBGA153%5D/
