Looking for image ROM recovery android tv-box rk3188 rtl8723bs 4k

[cooman342]

I have this Android TV Box which I somehow messed up by playing with the settings. It no longer boots up properly, just showing green droid images. The only thing written on it is Android TV-Box. There's no model number or manufacturer name. On the bottom, it says ANDROID TV-Box 4K Ultra HD. I found some recovery images, but they "check chip fail" when trying to recover the firmware. I included images of the unit and the circuit board.

Please help me the find the recovery image. Thanks so much!
