What is the safest way to update ASIC firmware?

Verify the exact model and control board, download from official sources, back up settings, and update on a stable power and network connection.

What should I check before flashing?

Confirm firmware compatibility, read release notes, and prepare a rollback plan to stock firmware. Avoid files from unofficial mirrors.

Why does control board compatibility matter?

A mismatched control board is a common cause of failed flashes and boot loops. Always match the firmware to the correct board revision.

How can I reduce the risk of bricking a miner?

Do one change at a time, avoid power loss during flashing, and keep recovery media (SD image / rescue instructions) ready for the exact model.

Are custom firmware gains worth it?

Custom firmware can improve efficiency or add features, but results depend on model, cooling and silicon quality. Start with conservative profiles and monitor stability.
