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.
