I was having the same problem until I reset the Jetpack by taking the battery and sim card out, wait 30 seconds, and then re-install. This will put everything back to factory defaults.Then I was able to get the new firmware.Worked for me, give it a shot.-- ... need help? »evdo-tips.com/
After you did the battery and SIM pull did you then connect to the unit using WiFi and download the update from the built-in web portal or did the update just "automagically" show up on the unit?
wifi and portal , it did not show up automatically-- ... need help? »evdo-tips.com/
OK, thanks. Will give it a try when I get some time and report back on success or failure.
