This morning I upgraded to cm-11-20140505-Snapshot from cm-11-2014-05-04-Nightly. Upon boot into the new snapshot image my home button and notification tray stopped working. The home button registers presses, but does not take me to the home screen. The notification tray does not register any incoming notifications and the quick settings pulldown is inaccessible.
Upon noticing these issues I rebooted(no change), Wiped Cache and Dalvik(no change), flashed back to cm-11-2014-05-04-Nightly again(no change)
What can I try next to get the system working again?
