Glad to hear the new calibration worked for you!
The latest official firmware is 20260702 so the MFU will update to that. 3.0 is in beta over here. Once 3.0 is out of beta the firmware listed there (which has white balance among many other improvements) will be the latest official one. Midi_Fighter_Twister_20260825 was a test build for you to try out. 20260702 doesn’t know what to do with the calibration bits and it’s why the hue returns
2.92 shows it in the log
3.0 does it in the device selector menu
The reason newer beta firmwares still show the update prompt is just to keep an easy way to downgrade to the latest official build.
