Upgraded to WP 8.1; network now not recognised

[WPCentral Question]

Hello. I updated my Nokia Lumia 920 to 8.1 yesterday and now the phone is not finding my network. I put another sim card in there and that was recognised so I'm wondering if anyone can help me in identifying the problem with the phone.

There was an thread about this problem and the 920's, the steps you need to do before updating to 8.1. "Do this if you want everything to work on your 920", look for that title and it explains it .
