I upgraded Verizon Access Manager to version 2.7.2.1 (2462a). Every time I start it, it tells me there is a firmware update availalbe. However, following either the instructions through the Access Manager per http://search.vzw.com/?do=viewdoc&id=27030&supportview=1&p=-1 or wit the Access Manager closed and the running the firmware exe directly, it fails to complete the MiFI firmware upgrade from 125 to 135. All I get is a message box that it failed. Any hints?
