help bb curve 8520 wont turn on

help, my bb wont turn on and it wont charge, the battery will charge in my daughters curve, so it cant be the battery.  when i put the charged battery in the red light just flashes and nothing else happens.  if i put it on charge with a half charged battery the charge symbol comes on the a red cross appears over it, even putting my daughters battery in it wont switch on.


i've obviously pulled the battery, sim and memory card, tried putting charger in before the battery lots of times and left it for ages. its been like this for a few days now Smiley Sad  any help much appriecated. thank you.

Re: help bb curve 8520 wont turn on

Try this:
Leave the device to charge 2-3 hours, and then, still connected to the charging cable, remove the the battery from the device a few seconds and reinsert it. If it boots--leave it to charge to 100% (check Options > Status for the percentage). If it doesn't reboot on the first attempt, leave it several more hours. I've had one charge for two days before it came back to life after an extreme battery depletion. Every 3-4 hours, with the device still connected to the charger, you can remove and replace the battery to see if it reboots.
