Hello, I just updated my Nokia Lumia 800 to WP 7.8 with 1750.823.8858.12460 firmware, variant RM-801 VAR EURO1 GB CV MCYAN (059M539) using Nokia Care Suite.
It has been installed without any problems but when I turned the mobile on, it asks me for PIN code and then for PUK code.
I am on O2 pay & go. I was trying to solve this problem with someone from o2 customer service, he was sure that he's giving me the right code but it was not working.
When I try to put this micro sim card to the other mobile, then it works and different phones does not require any codes. It is something wrong with my lumia 800 after that update.
What to do now?
