[Windows Central Question]

i got a notification from nokia, asking me to update my phone to the latest version of windows. The message said i will not be able to use my phone for about 10 minutes while the update is runing. After lunching the update, the update process has been hanging for the past 4 hours and the phone is not usable any longer. After four hours the batery went off, and i recharged it, but it still has the update running. The update progress bar is not flowing. What can i do? the phone is a nokia lumia 720.

Try a soft reset. Press and hold the Power and Volume down keys simultaneously for 10-15 seconds.

If above does not work and you have a SD card. Get the SD card out try again.
