If it's always been an unlocked sim free phone you can flash the firmware again with Odin.
It looks like there is some corruption in your current firmware that a reset can't fix.....

Text ACTIVE to 2020, save the settings and reboot the phone. Search the network settings and try to connect to O2 manually.

Also try cleaning the sim card and check for any network problems on the status link in my signature.

I would try resetting the phone again and if no luck try as Jonsie says and see if you can select the O2 network manually
