How to Fix a Nuked or Bricked BlackBerry on PC and Reload the OS

A BlackBerry Smartphone which sits in a constant reboot or displays a 507 error is not something that any experienced or inexperienced BlackBerry user likes to see.

There are a few reasons why a BlackBerry device may be bricked, such as an operating system update didn’t load correctly, or a 3rd party app is in conflict with the operating system.  It could also mean that there is a memory leak, or some other compatibility issue. When this occurs, the device is considered nuked or bricked, but if these steps are followed, it is simple to fix the device, and reload the operating system back to it’s original factory settings.

As long as regular backups have been made of personal settings, emails, etc., it is possible to reload all information back onto the device after this repair has been made.  If backups have not been done, after this repair,  the device will be reset to factory conditions, but will remember the carrier identification.

Here you will see the Operating System files that will be loaded onto the device.  Normally, if upgrading to a leaked or official Operating System from a different carrier, the Vendor.xml file would be deleted.  In this case, it is not deleted because the OS that is going to be loaded on is for the carrier of the phone.

NB: It was attempted to load another carriers OS on the device used for demonstrating this, by removing the Vendor.xml file, but the OS refused to load, and the 507 Error Screen continued to be displayed.  It is highly recommended that when fixing a bricked BlackBerry to use the original carriers OS.  After the OS is loaded, these same steps can be used to load onto the phone if wanting to upgrade to a leaked or official OS from a different carrier, but the Vendor.xml file must be deleted.

The Communication Port Selection screen will be displayed and the connection will be blank.  This is a very important step where speed is essential.  Plug in the phone, (do not insert the battery)  and the sound indication from the PC will indicate  the driver being installed from the BlackBerry device.

This screen will stay up, but the connection will change to unknown, and the next button will be made available.

The connection box will now change to USB-PIN:UNKNOWN. This is where the NEXT button must be clicked quickly.

If the BlackBerry device has been displaying the 507 screen, urgency isn’t required, but if the phone has been caught in a constant reboot stage, it is imperative that the next button is clicked before the Application Loader reads and identifies the PIN of the device.

If the PIN displays, cancel the whole process, unplug the phone, and restart the whole process again, ensuring that the next button is clicked before the PIN shows.  This is what stops the phone from rebooting from the damaged Operating System.

    One for the books, great how-to Geof!! Going to be saving this one, just in case… Thanks I know this will come in handy some day.

    Does not work. The “connection” box is blank and when insertion into usb, it immediately changes to my pin number. No UNKNOWN appears at any stage.

      • Marco says

        Found a fix. Uninstall DM and the new OS from Start – Control Panel – Remove Programs. Re install them again. The AppLoader seems to remember the pin and will show it immediately.
        You have now removed it from memory as you reinstalled it.
        Double click on the AppLoader file and plug in your device without the battery installed. Go through the sequence to CONNECTION.
        The connection will now show COM1. Insert the battery and it will change to UNKNOWN.
        Click NEXT quickly and the rest will be a breeze.
        Good luck and post back.

          Marco,

          I tried your solution over and over again uninstalling and rebooting–even clearing the PIN from the registry, but I could not get the device Connection screen to come up without the PIN. I did eventually resolve the problem though.

          When all seemed totally lost and I was resigned to taking it to an ATT store to reimage, the simpliest of solutions occured to me–and you led me to it.

          Above you stated that what worked for you was getting the PIN out of memory–something that my device refused to do. So I fired up the Desktop Software, went to the DEVICE menu, and selected FORGET DEVICE. OMG how straight-forward was that. It’s so simple when the right answer just smacks you in the face!

          Once I clicked FORGET, I just proceeded with updating the device (as described in the 507 fixes), which prompted me to unplug, reboot, and then, after reboot, prompted when I needed to plug in again. I didn’t have to pull the battery or worry about the timing of my connecting, or run the Loader again. All was accomplished in the Desktop Software.

          So after 3 days, and too many hours trying to resolve this problem, it is done. Hopefully the simple trick of disassociating the BB from Desktop Software will help others to solve this problem more easily in the future.

          – JB

    Hi!
    My problem is a bit more complicated. I have a bb 8520 that shut down by itself but it never starts again, so the screen stays always black, with the red flashing light blinking 5 times continuously. So I can never get apploader to recognize it, nor does bbsak.
    I installed a new os a few days ago, that might have caused this. Any suggestions? Waiting for your reply.
    p.s. this is the os: 8520wifijAllLang_PBr5.0.0_rel1831_PL5.2.0.111_A5.0 .0.1106_AXIS_Indonesia

  11. Jeremy says

    when i already clicked the next button there was an error saying “A fatal error has occurred while updating your device’s software. Please try again.”

  12. Stephen says

    I get the error unable to connect to JVM wtf? I tried to load older versions and new versions on my 8520 curve still just a white rectangular square or sometimes the red cross. My other 8520 curve is completely dead no red light nothing. please do not tell me it’s the battery cause it’s not. What to do? File 13 seems like an option.
