Hi everyone, I just upgraded my Samsung Galaxy S2 from ICS: MIUI 2.7.13 to latest JB: 3.4.12. All went well but now, every time I reboot I am prompted to enter my SIM network unlock PIN. I remember pretty well unlocking my phone a year ago when I first started using MIUI. And I never had this issue on any of my previous upgrades. The probem is that now, I can't use my phone because it won't log to my Network (Orange in France). Anyone can help me?
