Hello all well this is my problem.ones about every 3-4 times flashing after a random soft reset i get no call service my web and sms work fine but my calls do not i have simply a circle with line across similar to the "no smoking sign" i have seen it with just about every rom ive flashed before i use sashimi after flash but have seen it before i started using that program.i dont know if its something im installing because i install the same things a hard reset later and all works fine.hard reset is not an issues but just gets annoying when having a flashathon day LOL i appreciate anyones help good day.
