Ok I’m saying it’s a bad board or a firmware issue, I’m thinking of selling it or sending it to someone to be diagnosed and possibly fixed. Is there anyone that could diagnose these for a reasonable cost?

S9j worth anywhere between 120-140$ nowadays, it's won't make sense to send it for diagnoses as that will cost you anywhere from 50$ to 100$ in most places, with no guarantee that it will work again without having to buy a new control board at least.

But let me tell you something, it's extremely difficult to brick a control board just by using an sdcard, I flashed hundreds of S9s and never managed to brick one, it either works, works halfway or doesn't work at all, if the power didn't cut in the flashing process the control board is probably still ok.

Try a smaller Sdcard and flash the original bitmain firmware, make sure you get the jumpers correct, you might also try a hard reset, power off, keep holding the IP report button, power on while keeping your finger on the IP report button for 10 seconds.

You need to be patient when using Sdcards to flash any miner, I tried a few till I found one that works great, I don't know why but those miners are very picky about what Sdcard they like, also make sure you are copying the files in the main directory of the Sdcard, follow the steps by Bitmain very closely it should work.
