My problem started when I downloaded an app "Dumb ways to die" on my rooted Samsung I9000 with cyanogen mod 9. When I started app it just quitted from it to home screen.I went to the application options and force stopped it. After that,I received :"unfortunately android process acore stopped working" something like that.I rebooted the phone and got boot loop which i fixed via wipe cache,wipe dalvik cache etc(on reboot recovery). Everything was ok but I saw SuperNexus custom rom which I installed. I got problem with SIM card (I am on T-Mobile). My phone just didn't recognize my SIM card. I went installing google apps for android 4.2.0.,and for few of them i received errors:unfortunately android keyboard stopped working,something like that and more of it ,and my phone was frozen.Fortunately i found right one and installed it and it works good.But my phone keeps turning off by itself.And i still got SIM card problem.

Please help!

Thank you!

Sorry for my bad english ,and not fully (maybe) explained problem!:)
