Install on one miner
Select the model and board to check the matching package. Similar model names do not make files interchangeable.
Check the existing firmware
Open the miner’s web interface using its local IP address. Check the installed version and build date against the developer’s prerequisites below. Ask for help if the installation route is unclear.
Keep the matching archive intact
Choose the file for your exact model and control board. Keep the .tar.gz archive intact in a local folder; Toolkit installation does not require unpacking it.
Select one miner in Toolkit
Create a network group for the miner's local IP range and scan it. Confirm the detected device, then select just that miner and open All Commands → Install firmware.
Install, then check the result
Point Toolkit to the folder and choose the matching build and version. Review the local operation before confirming it. Follow Operations, then verify the installed version, pools, temperatures and hashrate before adding more miners.
Confirm this is an update
Check that VNISH is already installed and read the release notes for the chosen version. Confirm that the exact model and board have an update package.
Back up and select one device
Save the current settings. In Toolkit, open the device's network group, select one miner and choose Commands → Update firmware.
Use the update package
Choose the folder, firmware build and version for the update archive. Follow Operations and verify the device afterwards. If no matching update file is listed here, ask us before choosing another installation method.
Read the complete model label
Record the full device variant, not just a family such as S19 or S21. Find its IP on your own network and open the current web interface.
Confirm the control board
Read the device information or use Toolkit's detected platform. Our labels are AML, XIL, CV and BB. Do not choose one only because another miner looks similar.
Check the installed stock build
Record the firmware version and build date. Check the developer’s illustrated prerequisites, or share these details with support if you are unsure which route applies. Do not send credentials.
