I tried with braiinsOS+, nicehash firmware, and an old version of bitmains firmware but this error persisted.
The result will be pretty much the same regardless of which firmware you try to flash
Did at least I got ride of the virus you think?
I can't tell, but we at least know your miner isn't making the hacker richer now, you still need to fix it, let's hope the Sdcard flash does it.
