Re: My blackberry bold 9780 caanot turn on and LED light keep flashing and can't connect to my PC as well

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!

Hi asyikin_azis,

Try this:
1. Connect your blackberry to computer using usb cable. If desktop manager automatically open, then close it because it will not able to detect your bb at this moment.
2. Open apploader.exe from "C:\program files\common files\research in motion\apploader\apploader.exe"

3. Apploader window will open then click next twice and your blackberry LED will stop blinking and start to boot normally.
