µTune Updates

Here you can download the latest µTune firmware version.

This is how to install the firmware:
– Extract ZIP-file, you will get a file ‘uTuneFW.ebi’ and may also include the file ‘uTuneExp.ebi’
– Put the file(s) in the root directory of your SD card
– insert SD card in µTune and go to CONFIG->Misc->Expert Settings->Firmware Update (HW 16?*)
– The updater will start and firmware will update
– After the update you must reset the settings to default. (Newer firmware versions will do this automatically if needed and display an info message). Your previous configuration will be lost.

If you are coming from firmware version 2.11 or lower, you will need to also update your expanders. See Updating µTune expanders
