Blackberry Bold 9900 keeps rebooting

My Blackberry bold 9900 keeps on rebooting. The problem occurred when I switched on the phone after a 6 hour flight. I have removed the sim, memory card and battery but noting doing. It keeps rebooting.  Can anyone help on how to solve this issue. Thanks

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!

I went through the same problem too!First of all make sure you have BlackBerry protect!Back up your data!Then if you have BlackBerry Desktop Software Manager make a back up of your BB as well!Wipe your Device including User installed apps!Then restore your data from back up!
