Click the General icon located in the left panel. The settings menu appears on the screen as below:
Press the button 7—for seven times—on the remote control. Then the Software Update menu gets launched as shown below.
Select the firmware file to update with.
Because you are downgrading your firmware (i.e. updating with a version lower than the installed), please enable the Ext. MICOM* option (marked in red above).
Click the UPDATE button to start updating with the selected firmware.
*Enabling the Ext. MICOM URSA (or Ext. MICOM option) allows updating firmware regardless of the micom version already installed on the device.
