Tool for this job

Install Toolkit 1.7.3 (audited by our lab: installs your local ROIASIC file, phones nowhere for firmware) - pick your platform below, SHA-256 published

Step by step

1. Download the install file above and check the SHA-256 matches
2. Install the toolkit on a computer in the same network as the miner
3. Create a group with your miners' IP range and let it scan; select your miners
4. Choose Install firmware, point to the folder with the downloaded file and confirm - the toolkit's name and version fields can stay at defaults. Do not cut power while flashing ⚑
5. Open the miner web UI: set your pools, pick a preset, watch the first hour

⚑ owner confirmation required - do not run unattended

After the install

• Set your own pools and worker names
• Start with the efficiency preset for the first 24 hours
• Watch temperatures and hashrate for the first day
