Guys, you've backed up NV, but have you erased it?
Maybe it's poisoned with some corrupt record which makes firmware crash?

No, rgn41 is not erased. If that is recommended, please provide instructions how to replace it by a non-corrupt version.

Considering the symptoms, that's my thought too. Won't be home until 1500 UTC, so can only proceed then.
