Exact hardware onlyNever install firmware intended for a different miner model or control board. A similar product name does not establish compatibility.
1. Choose the exact firmware
Match the miner model and, where documented, its control board. If a release does not explicitly cover your hardware, do not install it. Model-specific instructions are pending unless shown with that release.
2. Verify the download
Calculate the downloaded file’s SHA-256 checksum and compare every character with the checksum displayed by MaiMiner. Do not use a file if the values differ.
3. Back up the miner
Export or record the current pool configuration, network settings, worker names, and any settings needed to restore operation. Keep the original or recovery firmware available.
4. Install by release type
Web-flashable release
- Open the miner’s existing web interface.
- Use its firmware upgrade page and select the verified MaiMiner file.
- Follow the instructions saved on the specific release. If none are shown, model-specific steps are pending—do not guess.
SD-card installer
- Use a suitable SD card and the preparation method stated on the release.
- Write or extract the verified package exactly as instructed.
- Follow the release’s boot and completion indicators. If they are not documented, model-specific steps are pending.
Recovery firmware
Use recovery releases only for the exact supported model and recovery scenario. Preserve the existing configuration and follow the release-specific recovery instructions.
Maintain stable powerDo not power off, reset, unplug, or interrupt the miner during flashing. Interrupted installation can leave the controller unable to boot.
5. Reconnect and verify
Allow the miner time to restart, reconnect to its web interface, restore or configure pools and worker details, then verify hashboards, fans, temperatures, power behavior, and pool acceptance before considering installation complete.
Troubleshooting an offline miner
- Wait the full restart period specified by the release.
- Check Ethernet, DHCP leases, and the miner’s previous and newly assigned IP addresses.
- Do not repeatedly interrupt power.
- Use only the documented recovery procedure and exact recovery image for that model/control board.
- If no model-specific recovery instructions are published, stop and contact support rather than experimenting.
