I updated some SB1s at a customer location via MSP yesterday. The update completed and they were working fine but when I powered them down and back up they are unusable with odd screens showing and no way to get to settings, the applications or any other useful screen. The attached pictures show what the screen looks like after the power cycle - PostUgrade1 is the fist screen, hitting the back button will return you to the Home screen but hitting any button on that screen (Applications, Settings, Badge, Notifications) will only take you to the screen shown in PostUpgrade2. Any suggestions on what caused this or how I might be able to recover them other than putting a developer back on them? They have others that need to be upgraded but I can't until I figure out what caused this. Thanks.
