Hi! I have been using a bb 8320 for 3 months. Suddenly it's just turning itself on and off- white screen with hourglass for a few secs and then a red light appears for a few secs too. This happens over and over again. I have tried re-charging and flashing it with the 4.5 OS but I got this error msg: error 547 JVM failure to write...or something to that effect. Then there's a whole list of commands to choose...i just chose reset and then again went on and off thing. Can you guys help me please?
