8520 won`t boot

Hello everyone i have a bb curve

and it whont start and i did  this

 (1) Make sure you have Blackberry Desktop Manager installed.
http://na.blackberry.com/eng/services/desktop/
2) On your PC, go to Start > Run and copy and paste the following line exactly (meaning with the quotation marks):

"c:\program files\common files\research in motion\apploader\loader.exe" /nojvm

3) The Application Loader Wizard will appear -- click "Next."
4) In the "Connection:" drop-down menu, you should see "USB-PIN: UNKNOWN". Click the "Next" button.
5) You should then see a list of applications ready to be installed for your Blackberry. Hit Next and Finish and you are well on your way to getting your Blackberry back to life. Congrats! Just don't disconnect anything and let the lengthy process finish completely.this one dint work ...

NOTE: If you do not see a list of applications mentioned in step 5 and instead see the message "The Blackberry Desktop Software does not have Blackberry Device Software for the device that you have connected to the computer. Contact your wireless service provider or system administrator," then you must download Blackberry's Operating System for your carrier and device.

Just select the appropriate carrier and network type, select your Blackberry model from the list and download the latest version. Install this download and follow the above steps again and you should be on the right path. ) but this one did in a way but  my phone disconnect automatic coz it stats to boot up again  but not all the way please help me i dont know what to do.

thank you very much

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.


 

It may also be that you need to use a different trick with the procedure you are following...see these:

  • KB10144 How to force the detection of the BlackBerry smartphone using Application Loader
  • KB27956 How to recover a BlackBerry smartphone from any state

Good luck and let us know!

Re: 8520 won`t boot

Well, that would depend on exactly what you are doing. I gave you two different processes, each with more than one step. From your response, I've no idea what you are doing...please provide details.

If you are on the first process (4h15m), on step 2, then please re-read that step...it says to leave it alone for the entire 2 hours, no matter what the display or LED shows. Hence, your "its not charging" concern would be moot under this circumstance.

Further, are you 100% certain that the charger is functioning? I did say "known good"...you must be certain that the charger works properly, and for this test you cannot depend on your BB to provide you that information.

Further, you marked this thread as Solved...is it so?

Re: 8520 won`t boot

OK...but beware that "new" and "known good" are not necessarily the same thing. While rare, "new" items certainly can be defective.

To have a truly accurate test, one must truly find "known good" items to use -- in other words, items that, independent of your BB, are tested to be properly working. Usually, that involves finding a friend with an identical BB who has no issues such as yours (sometimes, the friendly folks at your local shop might be willing to help)...using their battery/charger would therefore positively meet the "known good" condition..."new" items would be something less than positive in that regard.

Good luck!
