Fixing a bricked(?) Xiaomi R3P

Hi, I apologize first if this is the wrong section to ask in. I have previously flashed OpenWRT with success on other routers. I bought a Xiaomi R3P recently and attempted to flash OpenWRT on it, and after the reboot command, I ended up with a blue light on the router, no wifi signal from it at all, and no ethernet signal when I connect an ethernet cable. I think it is possible that it is bricked.

I am thinking that using UART etc. may be my solution to fix it, but I have never soldered something in my life before, but would not mind getting into it. Please help me out, as I don't know what a possible solution is. Thank you!
