The Handera I got off of Ebay has major parts of the OS removed, in particular the CFBackup utility, which makes the device essentially worthless for travelling with. The Handera website has several OS upgrades available, but they require loading an .UPD file to a CF card. I've done that, and followed the proper reboot procedure to get it to detect the .UPD file, but it does not detect it. Nor does it detect it on the SD card.
Haven't found the solution yet, but here are some things that I found along the way.
A nice history of Palm OS upgrades:

Probably my issue is one of the Handera not being able to access the card slots due to the destroyed OS. Not sure if there is any way out, but this forum page has a link to something called SyncWizard which looks pretty neat:
