  3. I just installed the update 4.4.2 via internal phone procedure (about phone, software update – download, install).
    Now the phone resets itself every 30sec.
    I can unlock, but cannot lock.
    It is just unusable – resetting every 30 sec. Looks like reboot, but does not ask for SIM unlock.
    Any idea?
