I unlocked a Verizon 9650 bold and Im using t-mobile service. When calls get disconnected the phone shuts off, the blinking red light comes on with hourglass. I can do a battery pull and charge and after 15 mins or so it will work. Trying to fix it and would appreciate any input. Thanks.
I found out that this was the battery. Upon closer inspection the battery was swollen possibly due to overcharging. I left it on the charger when I was out of town for two weeks.
