Nokia Lumia 925 network selection problem

Question

I updated my Lumia 925 to Denim, but a strange thing happened after the upgrade; I can't select 3G. The drop-down list freezes on 2G. How can I fix this?

Answer 1

As Apoorv mentioned you could try and make a reset. But before that you should:

1. Check if there is another update available. Including installing and running Upgrade Advisor from Store.
2. Remember to have backup activated before you do.
3. Take note that there are two kinds of resets that you could do: Hard and Soft (always try soft first). You can read how to do both kinds of resets here.

Answer 2

Why dont you try to reset your phone ! Try to reset it and then see. Sometimes the firmware do creates problem so resetting is the only fix
