i have a blackberry bold 9900 for about a year now and a couple of days ago my device turned off and never went back on again. i have tried leaving it on the charger for several days but still nothing and then i went on to reload the software and still nothing, the only thing i notice is that as much as i charge it and then take the charger off it turns off in several minutes. It is always stuck 75% through the loading screen even when i connected my blackberry to the computer and did a reload to the software. please help!!
