If the OTA bricks your phone, there is no reasonable fix. You cannot SBF to a previous version.
I haven't been on much for medical reasons but I think a general "Update at your own risk" warning should go out on this latest OTA. I've received a number of calls from the local Sprint service centers regarding bricked Photons from this latest update asking me if there was any way to fix it. With the high number of bricks and no resonable way fix it, in my opinion, this makes the latest OTA very bad news.
