Find the correct firmware for your miner

Select your exact miner model. Add the controller and storage type only after checking them on your device.

Check the exact model, controller and storage type before downloading. Do not select these values by guesswork.

Get the HashCore Toolkit

Use HashCore Toolkit to discover supported miners, monitor devices and perform available installation or maintenance operations.

Download for Windows Download for macOS Download for Linux Download for Android

Use the Toolkit only for supported miners and supported operations. It can simplify installation and maintenance, but it is not the only installation route.

Install the firmware

Prepare the miner, upload the correct package and wait until the device completes the installation and reboots.

  1. 1

    Prepare

    Check the miner model, save current settings and ensure stable power.

  2. 2

    Upload

    Open the miner interface and upload the correct firmware package.

  3. 3

    Reboot

    Wait until the installation finishes. Do not disconnect the miner from power.

Verify that everything works

Before changing tuning settings, confirm that the miner is stable and all main components are detected.

  • The new firmware version is displayed
  • All hashboards are detected
  • Temperatures and fans look normal
  • Mining pools are connected
  • The miner is hashing steadily
  • A rollback or recovery package is saved

FAQ

Frequently asked questions

Will this firmware work with my miner?
Compatibility depends on the exact miner model, controller and storage type. Use the finder above or check the complete firmware downloads before downloading.
How do I identify my controller and storage type?
Check the miner label and the System or Firmware information screen. If either value is unclear, follow the hardware identification guide instead of guessing.
Should I use an install package or an update package?
Use an install package for the first switch from stock firmware or for recovery. Use an update package only when the miner already runs compatible ASIC Miner Group firmware; the installation guide explains both routes.
Do I need HashCore Toolkit?
Not always. Toolkit helps with discovery, monitoring and supported operations, but some miners can be updated through their web interface. Check the Toolkit compatibility notes first.
Can I return to the original firmware?
Yes, when you have the matching rollback or recovery package for your hardware. Save it before installation and use the recovery guide if you need to return.
What should I do if the miner does not restart?
Do not repeatedly power-cycle the miner or try random packages. Record the model, controller and visible error, then use the troubleshooting guides or contact technical support.

What is custom Antminer firmware?

Antminer firmware is the operating software that controls how the miner starts, connects to mining pools, reads sensors, manages fans and distributes work across the hashboards. Custom firmware can add clearer tuning profiles, detailed monitoring and more direct power controls, helping an operator balance hashrate, efficiency and temperature for a specific installation.

A firmware package is not universal. It must match the exact miner model, control board and storage type, and the correct install or update route must be used. Before flashing, save the current settings and keep a matching rollback or recovery package. During installation, maintain stable power; after reboot, verify the firmware version, hashboards, temperatures, fans, pools and hashrate before changing performance settings.
