Blackberry 9850 not turning on

My bb refused to turn on at all. I charged it overnight thinking it's the battery but still it didn't come up. I tried connecting to my laptop but bb desktop manager can't see it because it has not booted fully. The loading bar comes up but when it gets to a particular position close to the end of the bar it stops and don't respond to any key I press. I tried pressing the escape key while booting but still if the bar gets to that particular position it will stop. Does that mean my bb cannot boot again? Pls help me with a solution.

Re: Blackberry 9850 not turning on

Hi and Welcome to the Community!

Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain connected to a known-good wall charger (not PC USB):

  1. With the battery inside, connect your BB to the wall charger
  2. Leave it alone for 2 hours, no matter what the LED or the display does
  3. Remove the battery
  4. Wait 15 minutes
  5. Insert the battery
  6. Wait another 2 hours, no matter what the LED or the display does

This has been known to "kick start" some BBs.




It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:

  1. Obtain a known good and already fully charged additional battery...use it in your BB and see what happens
  2. Obtain access to a known good and identical BB...use your battery in it and see what happens

The results of this will indicate if it's your BB or your battery that has the problem.

Good luck and let us know!
