Got a problem I hope you guys can help on. I am running Liberty Rom 2.0 (for close to 2 years now) System version 5.5.886.XT875.verizon.en.US Android version 2.3.4 Build 5.5.1_8_DBN-55 Ok, so the problem started yesterday morning. I was texting back and forth with someone, and suddenly I couldn't send messages. I could still receive messages, but no sending. I still get data connection in terms of I still have internet access through my phone, but I can't make calls or send texts, and I have the flashing grey Triangle on top showing I'm roaming. I am in my home area, so i am not suppose to be roaming. I called Verizon, they checked the system, and determined that the SIM card must have went bad, so today i went to the store and had them switch out the card. Didn't fix anything. They are saying maybei I need a newer system version since the current one is 6.7.246.XT875.verizon.en.US. Before I call for the extended warranty claim to see if they will just replace the phone, i wanted to see if anyone knows if there is something else I personally can do to make it start working again.
