Sunnzo DQ6 maskrom

[paulvern]

Hi everyone, I own a Sunnzo DQ6 rk 3318 4GB ram. After a system crash I've tried to reflash some firmwares but all of them were not compatible with the wifi module in this tv box. So I continued to try until the box doesn't show up when connecting it to my pc and it doesn't boot either. Is there a way to short some pins in this board? (I must admit I don't even find the flash rom module).
The following are some pictures of the board.
Thank you for any advice.

Hello, I am in the same situation as you. I have that tv box when trying to load a firmware it stayed in MASKROM. I can't get back to LOADER. Whenever I connect the tv box to the pc it is in MASKROM. Do you know how to solve that problem?
