long story short i took apart my phone the screws under the battery cover to try and fix my head phone jack cause it no longer worked. so after putting every thing back together i get no service at all no data no nothing. i try and make a call it says "mobile network not available". i was rooted and running a custom rom. i did a recovery back to stock and still got the same thing. i even tried using odin to flash back and still got the same thing. Under the status options it says network searching for service mobile network type unknown and service state out of service. the phone also keeps asking me to go into global mode. ive tried taking out the sim card and put it back in with no luck. maybe its a bad sim card? can anybody please help!
