A3 with L 3 firmware

[dinotom]

I was having a problem with one of my A3’s. I tried everything to get it hashing. Last resort was to backup another one and reload the non-working one’s firmware with the backup from a working unit. Could never get unit to flash green, and deep in the logs I noticed some problem with one of the fans so I replaced it. Booted it up and now I am flashing green, but NO hashing. I looked at system tab and.... what? It says it has L3 firmware. I tried flashing with a new A3 backup from another working unit, and it completes the process. I look back at system tab and wtf, it still shows having L3 firmware. Anyone have any thoughts on how to resolve this issue?

Go to bitmains website and download the A3 firmware from there then flash it.

Sounds like your A3 was delivered from Bitmain with the L3+ firmware inside by accident.

If this is the case, then I suggest you do what klwolf2000 recommended to do.
