Store the file in the root folder of a USB-stick or microSD-card.

Step 3. Insert the device

Note that you will see a warning “Not using media for storing logs”. That warning can safely be ignored.


Step 4. Initiate the update

Navigate to Settings → Firmware → Offline updates.

Press Check for updates

If the firmware in the microSD-card or USB-stick is newer than the running one, “Update available” item will appear, press it to start the update process.
