I remember the software to update the firmware was hugely hit and miss, you had to do some stupid thing like plug it in, take out the battery, unplug it, put the battery back in, plug it in, unplug it, take out the battery, plug it in with the battery out, put the battery in, unplug it whilst holding down the back button, keep holding the button, take out the battery, put the battery back in, then plug it back in, release the button, then you'd get an error message saying it couldn't find the flash drive to do the update. Then even if you did update, the firmware was less stable than nitro glycerine in the possession of Michael J Fox.
