How to choose the correct firmware package

Match the exact miner model first, then the controller and storage type. Choose an install package when moving from stock firmware or recovering a miner. Choose an update package only when the miner already runs ASIC Miner Group firmware.

Firmware packages

Find the correct Antminer firmware package before flashing

Firmware package selection depends on the model family, control board, storage target and release status. A wrong package can create downtime, so the download page is organized around practical compatibility checks rather than a single generic file list.

Use the filters to narrow the available builds, then confirm the flashing method in the installation guide. For larger fleets, prepare a repeatable rollout with the firmware toolkit and keep a tested rollback path ready.
