S19j Pro Controller Board Issues

So I got this s19j pro and the controller board is acting up. I've spent countless hours trying to reflash it using an SD card, but no luck at all. Is there any chance this board is totally bricked or is there something else I can try to fix it?

What firmware have you currently tested? If it's a stock firmware would you mind trying Braiins OS? I heard that they developing firmware that supports beaglebone except for the Armlogic board you can read more here Bitcoin Mining Control Board Variations Explained If it doesn't work you don't have another choice but to replace it with the universal one where you can able to flash it with mod/custom firmware like BraiinsOS.

I think its a 2.3 BB Board. I will hunt around for the Brains OS and see if I can get it working with that. Thanks for your help!
