We have identified a critical issue affecting Gen 3 bootloaders in DeviceOS releases 1.2.1 - 1.4.1.
It has been confirmed to mostly affect some number of Borons, but other Gen 3 platforms may present it as well.
We have confirmed a fix and will be releasing a new DeviceOS version this week. As a temporary measure we are suggesting manually updating bootloaders on Borons using the binary from the GitHub PR.
