Use the Toolkit route when the miner boots and is reachable on the local network. If it does not boot or cannot be discovered, stop and use the exact SD-card recovery procedure for its model and control board.
Before restoring
- Record the full miner model and control-board type.
- Export or photograph pool, worker and network settings.
- Use stable power and a wired local network.
- Confirm that the selected stock image comes from the manufacturer and matches the hardware.

When to use SD-card recovery
Use model-specific SD-card recovery when the miner is not reachable, does not boot normally or the Toolkit cannot complete the operation. The image and preparation steps vary by controller, so do not use a generic recovery image.
- Reconfirm the exact controller before downloading the image.
- Follow the manufacturer’s image-writing and LED sequence for that model.
- Contact support when the controller or recovery target is uncertain.
