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.

Best practice: prepare recovery before changes

Keep the latest stock firmware archive and vendor download link saved.

Document your current settings (pools, IPs, tuning) so you can re‑apply them fast.

Keep a spare SD card (where relevant).
Test recovery on one miner before doing mass upgrades.

Common recovery paths

Different miners support different recovery modes. The common ones are:

1) Web UI downgrade to stock firmware

2) SD card recovery image

3) Vendor batch tools / rescue utilities

If the miner boots but is unstable, downgrade via web UI first.
If the miner doesn’t boot, SD recovery is often the next step.

After recovery: stabilize, then tune

After rollback, run at stock settings to confirm hardware health.

Only then apply undervolt/overclock or autotune profiles again.

Watch temperatures and hardware errors for the first hour.
Confirm pool shares are valid and hashrate is stable.

Monitoring tips

FAQ

Does rollback erase my settings?

Often yes. Expect to re‑enter pools and tuning settings.

Can custom firmware lock me out?

Some firmwares change access methods; always read vendor docs and keep physical access for recovery.

What should I do if only one hashboard works after flashing?

Roll back to stock firmware, check cables and logs, and confirm board temperatures. Don’t keep pushing higher power until stable.
