Toolkit 1.7.3
Tool for this job
Install Toolkit 1.7.3 (installs your local ROIASIC file, phones nowhere for firmware) - pick your platform below, SHA-256 published
Amlogic boards with stock from September 2025 also lock the USB port. The USB port must be unlocked first - write to support, we walk you through it
Stock firmware from March 2024 carries Bitmain signature locks. Install only through the toolkit flow (v1.7.1+). If the toolkit reports an ssh error, first update the miner with the newest stock web-update, then retry. Unsure about the exact board revision? Ask support before any stock update
Step by step
- Download the install file above and check the SHA-256 matches
- Install the toolkit on a computer in the same network as the miner
- Create a group with your miners' IP range and let it scan; select your miners
- 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 ⚑
- 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
- Keep the downloaded file - batch installs reuse it
- Test on 2-5 miners first, then write to us for individual terms on the fleet
Back to stock
Safety net: rollback to stock Bitmain firmware is built in and typically takes a few minutes including reboot. Custom presets and settings do not carry over - note your pools and workers first. Unusual board revision? Contact support to verify this hardware revision before flashing
