Okay so I love this rom. I installed it when it was at 1.6. I checked back to see if they had updated anything and wow it was already at like 2.1. I got to reading and found out that 2.1 uses a new kernel and would not recognize my 64 gig micro sd, so I installed 2.0. Everything works great except for one thing. In some areas, I cannot make calls. It acts like it is dialing, but never starts ringing and eventually hangs up. I am showing in some cases full bars. I am roaming, but I have full service. I have checked my roaming guards and roaming networks. Changed almost every setting that I can with no avail. Sometimes when I try to make a call, I will lose all bars of service. One thing to note, when in this area, I can still use my internet and 3g service, just no calls. Before updating, I could make calls in the area easily. I can drive five minutes down the road and make calls with no problem. I am figuring it is maybe a different tower. Also this area is roaming as well. I can make calls no problem. Just wondering if anyone maybe has an answer for this. I have searched the blazer rom official forum and have came up with nothing. Advanced thanks to anyone that may have an answer and for the help.
