Firmware Guidance

Model-specific IceRiver firmware support.

Use this page as the firmware entry point for KS series and AE series miners. Confirm the exact device model, verify MD5 checksums, and apply official firmware safely.

Important - read before flashing

Installing firmware intended for the wrong model can disable the miner, void the warranty, or create unstable operation. Always read the exact hardware name in the device web interface and match the firmware filename (for example ICERIVER-KAS-KS3-yyyymmdd) before upgrading.

Per-model firmware downloads

Pick the package that matches the exact model name shown inside your miner's web interface. Files are mirrored as .zip archives - unzip to reveal the .bgz upgrade file and verify the MD5 checksum before applying.

Each download links to a model-specific archive. If a build is missing for your unit, use the official firmware download portal.

Need the very latest build?

The official IceRiver firmware download page always lists the newest signed firmware. Open it in a new tab to grab the most recent release for your model and verify the MD5 checksum.

Pre-update checklist

  • Confirm the exact device model and current firmware version inside the web interface.
  • Download firmware only from the official IceRiver website. Do not use third-party firmware - it voids warranty and can damage hardware.
  • Verify the MD5 checksum of the downloaded firmware archive matches the one published with the release.
  • Use stable power and uninterrupted Ethernet during the entire upgrade process.
  • If you operate many miners, upgrade one first and confirm 24-hour stability before rolling out to the rest.
  • If the miner is functioning correctly, IceRiver does not recommend updating firmware - flashing does not increase hashrate.

Safe firmware upgrade process

Follow these six steps to upgrade IceRiver firmware without bricking the device or losing pool configuration.

  1. Backup pool configuration: note pool URLs, worker names, and passwords before flashing.
  2. Identify the model: read the model code (KS3, KS5L, AE0, etc.) and current firmware build inside the device web interface.
  3. Download the matching firmware ZIP from the official IceRiver website. Verify the MD5 checksum after download.
  4. Unzip the file - the resulting firmware will have a .bgz extension.
  5. In the miner web interface, open Firmware Upgrade and select the .bgz file. Do not power off or unplug Ethernet during the upgrade.
  6. After the device reboots, log in, confirm the new firmware version, re-enter pool settings if needed, and monitor the hashrate for 24 hours.
