Originally got hour glass of death the red light flash repeating itself over and over. Have tried reinstall following crackberry 101 nuked blackberry instructions, probably tried about 20 times always got unable to reconnect to the device during a multi-stage load operation during step 4 of 5 steps. Have tried with os 4.5 then tried os 4.2.2. BB is about 18 months old if that has any bearing on problem. Now only thing happening is red light blinks twice screen is totally black. Any ideas or should I give up.
