Most of the recent firmware from Bitmain have a signature lock that will prevent custom firmware from being installed. When installing the Awesome Miner firmware via the Antminer web interface the result may be an error message about missing signature for the firmware.
Awesome Miner can be used to install Antminer firmware and in many cases bypass the issues related to the signature lock on the Antminer.
To install the firmware via Awesome Miner, go to the toolbar: Tools -> ASIC Tools -> Update firmware. The firmware can be selected from a list and Awesome Miner will automatically download and install the firmware on all selected miners.
Awesome Miner can bypass the Antminer signature check on most Antminers with the following exceptions:
- Antminer S9, L3+: Bitmain firmware from July 2019 or later
- Antminer S17, T17: Bitmain firmware from December 2019 or later
To install the firmware on any of the Bitmain firmware listed above, an SD card must be used. SD card images can be downloaded from the Awesome Miner Antminer firmware page.
