Release Notes

This update contains a visual update. The purpose of this is to streamline the ui development of RigRunner to allow managing device settings conveniently in the future.

Features

The latest S21 Pro+ and S21 Pro (FR-1.96) stock firmware install features are now available.

Known Issues

• Installing UMC OS after uninstalling Braiins OS may not work due to Braiins OS leaving the device in a modified state. This can be resolved by using a factory reset, or otherwise wiping the device settings from the miner.
• Uninstalling on some versions may report failure because of a error related to detecting firmware labels. This is a benign issue -- the uninstall will still have succeeded.
