Not sure if I understood correctly but if you're seeing 127-127-127-127 temp readouts that's almost certainly a PSU issue. Try swapping PSU's with another miner that you know works fine to eliminate or confirm. I've had 127-127-127-127 errors on 4 different 17-series miners and replacing the PSU fixed every one.
so far installing the recover via SD and then flashing the most recent firmware seems to have made it run well again.
