You did a fresh PR1.2 flash, so i think this is unlikely to happen again in a short time.

I guess you used wifi-swither from the beginning PR1.0 or later to adress the wifi drain-bug? it is not needed anymore sinds PR1.1.1, i've had the same problem before which annoyed me enourmass!

i think this is just a process that got stuck some where, if the problem still persist we will hear from you again.
