How to install
ATTENTION: If you have BITMAIN firmware from March 2024 and later, you need to use this instruction to install VNISH firmware.
NAND INSTALL: Download NAND INSTALL IMAGE and VNISH TOOLKIT FOR 21 SERIES ( unzip, read manual how to install).
SD INSTALL: Download the SD IMAGE , unzip and read manual ( Use SD card to install the firmware (not more than 16gb, FAT 32) Insert the SD card with VNISH FIRMWARE and turn on the asic, if you pull out the SD card the BITMAIN firmware will return. If you need to update the version of vnish firmware which you are already using on the SD card or in NAND you need to download the firmware WEB SD update file and use upgrade function in the firmware.
After rebooting the miner with the CVitek control board with the vnish firmware, the stock firmware will return, you need to scan the network where the miner is located using phoenix-scanner in the background and the Vnish firmware will be restored automatically

Version 1.2.6 Rc5
📢 New Features:
- Added support for Antminer L9, Antminer S21+, Antminer S21+ Hydro, and Antminer S19 Pro Hydro (120 chips)
- Add advanced option:
- Ignore chip’s temperature sensors for Antminer L9, Antminer S21, Antminer T21, Antminer S21 Imm and Antminer S21 Hydro
- Maximum delay time before mining startup (delayed start of mining to ease power grid/infrastructure load) for all models
- Minimum number of operational boards required to start mining for all models
- Display miner consumption and hashboards from the preset (where the psu doesn’t give out consumption)
⚠️WARNING: Ignore chip’s temperature sensors and Skip broken temperature sensors – disables temperature-based protection. We are not responsible for any damage caused.
🚦 Improvements:
- Optimized fan control based on temperature
- The Stop mining in case of faulty chain behavior — if zero chips are detected on a hashboard, the miner will now enter an error state
- Chip ID is now shown in the logs when overheating occurs due to high chip temperatures
- Corrected model name display for Antminer S19 (126) and Antminer S19 (88)
- Enhanced overall miner stability
- Improved stability of work with pools
- Implemented various UI/UX enhancements
🐞 Bug Fixes:
- Fixed issue where domains would attempt to rebalance during pause
- Fixed issue where pools were lost after a power outage or miner restart
- Fixed miner pausing when resetting a preset or restarting the mining process with Resume mining after reboot disabled
💻 API Changes:
- Programmatically disabled boards are now included in summary/chains API responses
