Jetpack 6620L will not update firmware

[bj35473]

My jetpack will not perform a firmware update.  I have 1 that is currently running v1.4 and when I force it to check for updates it says it is already up to date but I have several other jetpacks of the same model that updated to v4.5 with no problem.  

I've rebooted the jetpack several times and restored it to factory defaults but still can't update the firmware.
