It was a pain. For me. I think it will be fixed, since the fixes are fairly straight forward. My recommendations to Mooer would be: 1. Update the documentation to fill in the gaps. 2. Update Mooer Studio install process to either a) remove the old version, or b) give the user the choice to either upgrade and remove, or install the new version in parallel. 3. Update Mooer Studio so that the latest version of Mooer Studio is able to deploy the latest firmware (shouldn't have to rely on the old version of the software to deploy the new firmware). 4. Make Mooer Studio smart enough to go out and check for the latest version of GE200 firmware. OR just make it obvious where to get the firmware file to be deployed.
