Reset a BlackBerry using JL_Cmder on Windows 64-bit editions

The other day I had a person forget the password they set on their BlackBerry. After so many failed attempts the BlackBerry began to wipe itself.  The person then panicked and pulled out the battery… bad idea. The phone is then stuck in an inoperable state and cannot boot.  This is where the tool JL_Cmder comes in to save the day.

For this scenario I am going to use JL_Cmder 1.9.1, BlackBerry Desktop Manager 5, and the latest OS for my model of BlackBerry. I tested this example on Windows 7 64-bit edition, but it can be a 32-bit OS as well.

  • Install BlackBerry Desktop Manager (do an advanced install and remove the Automatic Update feature).
  • Install the latest OS for your BlackBerry model and if necessary remove the Vendor.xml file located in: C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
  • Download and extract JL_Cmder and set the .exe and .cmd to run in a compatibility mode of Windows XP Service Pack 3.
  • (32-bit OS users can skip this step) Remove CHOICE.COM from the JL_Cmder directory.

So let’s begin. Chances are your phone is at a menu asking you to Reset, but before you do… open JL_Cmder.cmd (from program files, not a desktop shortcut). Next, connect your BlackBerry via USB and press Reset on your phone. You should notice the icon change on your phone to appear that it has connected. Issue a wipe command, option 4, from JL_Cmder. Your BlackBerry will then reboot itself and you should see and error 507 on the screen. We are now done with JL_Cmder, issue option 7 to quit the application.

Finally we will reload the OS to your phone. Open C:\Program Files (x86)\Common Files\Research In Motion\AppLoader\Loader.exe and select which parts of the OS you would like to restore. I wouldn’t put stuff on that you don’t plan on using. The smaller the footprint the better.

Please feel free to leave comments if this worked or not. Any feedback would be beneficial.

  1. The problem with my Pearl 8220 (BB flip) started while the phone was in my pocket, just like every other day. No recent updates/upgrades, not even a recent sync. It just suddenly had a “JVM script error” and suggested to reload a module (forget which number). Anyway, nothing happened.
    So first I tried to connect and simply update my OS but this only led to the dreaded J:0x00000005 error with the “Reload Software: 507″ message on the phone.
    After searching the net for solutions I tried several, but none of them to any avail.
    Well, this is by far the easiest post to read and follow. All went well until ‘Loading applications’ in the loader. Just like with everything else I tried early in the process I got the Error message that says: “Application loader could not connect to your device. Please ensure that your device is connected securely to your computer and click Retry.” After clicking retry it stops at a different point but with the same message. It is as if the phone continuously disconnects and reconnects itself. Any suggestions would be more than welcome.

  2. How do i get it to run in a compatibility mode of Windows XP Service Pack 3? I right click the files but only have the general tab in properties. I am an admin for my computer.

    Thanks

  3. I upgraded to a new laptop, window 7 64 bit. Now I can not get my the calendar part of the outlook to sync. How do I get this to run properly. Thanks

  4. Just wanted to say thanks for this info. I hate having to use compatibility modes but it worked and now I have a nice stack of completely blank phones :)

  5. dm 5 and 6 detects my 9700 pin , but bbsak and mcp refuse to detect . how can i get them to detect so that i can wipe my berrry and start a fresh the last few hybrid loads have left the device malfunctioning . these were super safe icenfire hybrids that work well on my other device

    do email …

  6. I cannot get JL Cmdr to install on Windows 7. When I click on the exe file a widow appears indicating that JL Cmdr will be installed. I click OK and another window flashes on the screen for a split second and closes. There is an icon on my desktop, but when I double click it a message is displayed indicating that the cmd file is not found.
    I really need this to attempt to resurrect my BB9000.

  7. @John:

    The problem is that JL_Cmdr shortcut tries to look for the cmd file in the %Program Files% path, which maps to, on 64-bit windows 7, the “Program Files” directory. The problem is, however, JL_Cmdr installs to the “Program Files (x86)” folder, as it is a 32-bit program. Just change the location that the shortcut points to in its properties (right-click -> properties) from %Program Files% to C:\Program Files (x86)\JL_Cmdr and it should work! Good luck!

  8. Worked perfectly on Windows 7 x64 using instructions above. Initial install just flashes up a DOS prompt but exe can be found in program files (x86) and set compatability mode (XP SP3)
    Wiped corrupted 8700 OS and reloaded using latest BB app manager.

  9. I’m sorry, I did not get the last explanation u said about how to install JL-CMDR on windows 7 x64 bit version.
    Can u tell me how to do it in details please?
    Thank you

  10. HI I CANNOT DOWNLOAD THE JL COMMANDER WHEN I DO IT ASKS IF I WANT TO RUN AND INSTALL IT AND THEN A LITTLE BLACK BOX FLASHES UP AND DISSAPEARS WHAT AM I DOING WRONG?

  11. For some reason when i try to wipe my Bold 9000 with CD_CMDER it says it is unable to open port.

    I think that is the reason i can’t do the system restore. i dont know if my blackberry has a password on it. Any suggestions?

  14. you will have to download the desktop manager to be able to download the OS on your RIM. start up the DM, connect your device. it will ask for update or it will detect that it has no OS then it will ask for what OS one want on RIM. i guess you should be able to go on from there.

  15. Thankyou!! relief!!
    ..after finding this thread and installing JL_Cmder (with ni real success) I managed to get BBSAK detecting my phone (as this was the real reason I came to this thread) and managed to remove all the VAD (voice activated dialling which I never had any luck with due to not being able to speak as fast as, and sound like!, a synthesised robot) which free’d up about 2MB as I had GB English installed also due to trying to make it usable for me. I’m sure JL is a fine program, but the GUI in BlackBerrySwissArmyKnife did everything I needed and so much more. I also saved all my .COD files while I was at it which is something that has bothered me ever since I’ve had problems connecting my new Pearl 3G 9100 with my usual handy programs which I’ll check back with now that my BB detects.

    The thing that worked for me is:
    do a battery pull while your app is already running and like mentioned, “You should notice the icon change on your phone to appear that it has connected.” as originally mentioned at the start of the thread.
    cheers, hope this brightens you day and ends your trouble surfing.

  16. Steve’s suggestion worked great for me. After hours trying to troubleshoot JL_Cmdr on Win 7 64bit, I installed BBSAK and it removed the IT policy in about 5 minutes!

    Great suggestion Steve! I personally thank you for saving me many more hours and cash as well!

  17. Hi,
    I had a white screen of death on my blackberry curve 8900 occasionally. I would have to pull the battery and put it back in later for it to work. I read that it could be possibly solved with a re-installation of the operating system. This guide was helpful to re-install the operating system.

    Thanks

  18. Can it be implemented on Blackberry OS 7 such as Bold 9790 ? i want to upgrade my OS but still not sure what tools to use.

    Thank You.

  19. I cant open jl cmder. it opening then see unsupported 64-bit application .pl sent me what can i do .with regards

  20. How to perform a clean reload of the BlackBerry Device Software using the Application Loader
    by McAckron
    December 10, 2008
    This post is for those blackberry users who need
    assistance in BlackBerry device software reload. This
    process is also known as OS reload of BlackBerry Smartphone.
    Requirement:
    1. BlackBerry Desktop Manager software 4.1 and later
    2. BlackBerry Device software
    3. BlackBerry smartphone
    4. Windows based PC with USB port and BlackBerry data cable.
    If you do not have BlackBerry Desktop Manager and
    BlackBerry Device software installed on your computer
    Remember to install first the BlackBerry Desktop
    Manager and then Blackberry Device software.
    Procedure:
    Note: You should not install BlackBerry Device Software
    that is earlier than the version installed on the
    BlackBerry smartphone. Doing so could cause the
    BlackBerry smartphone to malfunction.
    For e.g. On your BlackBerry 8310 if you already have V4.5 device software then there is no point in installing V4.2 device software, doing so could cause the BlackBerry to malfunction.
    Before proceeding, make sure that the latest version of BlackBerry Device Software is installed on the computer by completing the following steps:
    . Open BlackBerry Desktop Manager.
    . Click Help.
    . Select About Desktop Manager from the menu and
    click the Device Software tab.
    . Confirm that the BlackBerry Device Software displayed
    is the latest version currently available from the
    wireless service provider.

    1) Back up the BlackBerry smartphone before
    proceeding
    BlackBerry device users can perform a full or selective
    backup of the data using the Backup and Restore tool in BlackBerry Desktop Manager by completing the following steps:
    . Connect the BlackBerry device to the computer running
    BlackBerry Desktop Manager
    . Open BlackBerry Desktop Manager
    . Double-click Backup and Restore
    . Select Backup to perform a full backup or select
    Advanced to perform a backup of specific databases
    . Choose a location to save the backup file, then click
    Save
    2) Blackberry Software installation process:
    To perform a clean install of the BlackBerry Device
    Software using BlackBerry Desktop Manager 4.5,

    . Type your BlackBerry smartphone password, if
    prompted and click OK
    . Click the check boxes next to the names of the
    applications you want to load
    . Click Settings,*(Desktop Manger 4.5 & 4.6 has Options
    tab below instead of Settings) and then click the check boxes beside Delete all application data and Erase all currently installed applications

    . Click Ok -> Next
    . Click Finish. It will take atleast 25-30 minutes to
    complete the entire process. During this time, make
    sure, your computer is ON and BlackBerry remain
    connected to the computer.
    . When the process has completed, the message The
    loading operation was successful will appear. Click
    Main Menu to return to BlackBerry Desktop Manager
    Note: The Delete all application data and Delete all
    currently installed applications options are not
    available when using the Application Loader in
    BlackBerry Desktop Manager 4.5. To workaround this
    issue, use the Application Loader standalone file by
    performing the following steps:
    . Open My Computer (or Computer on Windows Vista).
    . Navigate to C:\Program Files\Common Files\Research In Motion\AppLoader

  21. (32-bit OS users can skip this step) Remove CHOICE.COM from the JL_Cmder directory. >>>>> This step helps me a lot, after more than 5 hours, the application cannot open because of the error message which is written: Unsupported 16-bit application.

    then, I was back to the folder CHOICE.COM, delete it, and it continue running! :D

    thank u very much, for ur breakthrough tips!
