Hi I’m pretty new to this. If I may can I ask a few questions? I search the internet first but I haven’t found the answer. First I flash to Dutty ROM 4 and work great but it’s always trying to connect to Gprs network but it doesn’t? I just load up Garmin XT it only works if I have the phone in airplane mode? If not in airplane mode the phone lockup? Also when trying to use Gps tries to connect to Gprs? Thank you for looking
