BB 9900 Dead! Not Recognized When connected to PC!

Hi Guys, 

 

Will appreciate any help that comes my way.

 

So I used my Blackberry 9900 ( Carrier : o2 UK, OPerating system: OS 7.1) to make a call and noticed it was running out of battery. I then placed it on my table only to return to find it dead. I have tried everything from connecting the phone to 4 different computers, with and without the battery, I have also used about 3 or 4 other batteries and it still wont come on or show any sign of life. 

 

The worst part is whilst researching the issue online, I noticed other people mention a light or a sign comes up but with mine there has been no light, no sign, just DEAD! I tried the App Loader method but no PC recognises the phone when connected. The phone was never dropped or wet or ever misplaced or mishandle. I have had it for just over a year and this is puzzling. Any help will be very much appreciated. Thanks

Re: BB 9900 Dead! Not Recognized When connected to PC!

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!
