After upgrading your device you should always perform a hard reset. These are the instructions Ather90 wrote.

"Press ResetButton and hold down CameraButton + RecordButton.
Hold them pressed until the "Boot Options" menu appears on the screen.

Select the options as follows:
(for selecting use RecordButton, change values with CameraButton)

Enable KITL -> NO
Clean Registry Hive -> YES
Format Storage -> YES

When done, press DPad and wait until OS starts."
