Why do you still want to run this unit? It's no longer profitable; even if you have a $0.03 power cost, you'll earn negative $8 based on the mining calculator.
Do you have a free power source? If yes, then I think you want this to run for the lottery.
If that's the reason, try to use the Bitmain tool if it can detect it via that tool.
You can download it from here:

Let's hope it can detect and then flash the unit through that tool.
If it still can't detect it, then you'll need to flash the controller via RX and TX. We have an old guide here, but the problem is the image no longer exists.
