[dropcap]I[/dropcap]f reloading the OS of your Blackberry smartphone using the Blackberry Desktop Manager or Apploader seems not working for you because it is not recognized anymore by the desktop redirector, you might have to consider using JL_Cmder for blackberry to recover your crashed BB.
JL_Cmder is a little batch script to manipulate JavaLoader. The Java Loader can be used to easily display Device Info, display an event log, take a screenshot, wipe the handheld or reset it to factory conditions.
How To Use JL_Cmder for Blackberry
If you want to use the free JL_Cmder tool, download it on this JL_Cmder download page. I prefer the non-installer version. To install JL_Cmder, just extract the files into a folder. Whenever you want to use it, connect your blackberry with the USB cable to your computer and run Install.cmd from the folder.
On the first screen you will simply press a random key to continue the process. You will then be asked in the second JL_Cmder for blackberry screen if your device is protected with a password, choose yes or no (press Y or N). Enter your password if you press Y.
You will then be redirected to the a screen, where you will be prompted to enter the javaloader command you want to use.
Now to recover your blackberry OS, press “4” and don’t panic when you see the red screen, this is normal! it will just warn you that your complete blackberry OS will be erased. following the blackberry tradition, you will need to type the word “blackberry” to confirm erasing the blackberry OS.
After having completed this step, your blackberry should be completely cleared and ready to be reinstalled with the Blackberry OS release for your provider and downloaded from the official blackberry website.
Notice that JL_Cmder for blackberry should be used as a last resort only when all other means to recover your blackberry have failed. Mistakes or even the smallest issue might “brick” your blackberry (= unusable)
NB: It doesn’t work on 64-bit Windows and Blackberry 0.S. 4.0.2 or higher is required to run this file.
