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?

My TX3 Mini S905W was brick and I'm having problem identifying the short pin. It doesn't look like any images in the guides I found online.

Try with those pins...

I have tried many variants (short pin method) but it does not connect via usb I have the atv 4.0 on the box but I cannot finish the setup it does not show wifi and there is no connection via ethernet because the reset button has no function i cannot come beyond the setup, then I can't choose anything..
