What can I do if the firmware update doesn’t automatically start on Expert or Expert pro?

A firmware upgrade takes about two minutes to be completed; a progression wheel shows the progress on the screen. 

If for any reason the upgrade process doesn’t automatically start, please make sure you have followed the upgrade instructions detailed in the online user guide.

We strongly recommend you to go through the procedure step-by-step and check the following points:

  • Has the SD card been properly inserted?

    The SD-Card has to be inserted with its contacts facing up in its slot located at the rear of D-Premier and contacts facing down for 120, 200, 250, 400 and 800. Make sure it is inserted all the way until it locks.

  • Are you using an appropriate SD card?

    If you run a 5.4 or previous firmware version, make sure you use a regular 2GB SD card and not a SD-HC card. In some rare cases, you will have to try with another SD-Card as the reading speed of a specific card can  occasionally prevent the D-Premier from properly reading its content. If you run a 5.5 or higher firmware version, regular 4GB and SD-HC cards will work.

  • Is it formatted the right way?

    Make sure the SD card is formatted in FAT or FAT16. We advice you to reformat it on the same computer you use to generate the files on.  

  • Have you properly copied the upgrade files to it?

    Make sure the files have been copied to the root directory and not a sub-directory of the SD card and that they have not been renamed or their extension changed. They should be directly saved from the website or extracted  from the downloaded ZIP file to the SD-Card. For example, opening them first on a Mac and then copying them on a PC connected to the SD card can cause problem.

Note: Once the upgrade has successfully been performed, please remove the files from the SD-Card.
