USB OS Upgrade

I got burned when I lost my signal during the last OTA upgrade for Bionic, and it never really picked back up once I was back in zone. Ended up having to do a factory reset. Can someone please comment on what should be needed for the tasty new upgrade we're expecting if we elect to go USB instead of OTA. Thx.

(P.S. Did go pretty deep in the treads, but couldn't find this answered, so please pardon the new thread if I'm Captain Obvious)
