Controlled installation sequence
- Confirm the exact Antminer model and control-board platform.
- Record the current firmware, settings, hashrate, power, temperatures and pool configuration as a baseline.
- Download the build from this page and verify its SHA-256 checksum locally.
- Test on one miner within safe power and cooling limits, with a rollback route ready.
- Observe stability and expand only after the success criteria have been met.
A firmware change can affect manufacturer warranty, power draw, thermal behavior and hardware life. Use settings appropriate to your power supply, cooling and operating limits.
