Got a C52 control board that I was using for testing. Accidentally uploaded the S19 firmware and now I can't use it to test anything... Is there a way to roll it back to S17/T17 firmware? I tried just copying the S17+ firmware to the SD card, but it didn’t work. Is there another method to flash the S17 firmware using the flasherase and writenand commands if I can get SSH access to the board?
Thanks!
Have you tried other firmware to revert it back to the original firmware?
Try more firmware to bypass the signature check.
Try the guide and firmware here: https://www.zeusbtc.com/articles/asic-miner-troubleshooting/1183-s17e-t17e-s17-plus-t17-plus-control-board-program-recovery
If it still doesn't work, try other firmware like Braiins or Vnish firmware.
Or the test fixture firmware provided by the seller.
If nothing works then your last hope is to flash the controller via pinouts but the problem is there's no guide about it.
However, try this old method here below lets see if it would work on c52 control board.
