Are there any system requirements?
Yes. You must install BlackBerry Desktop Manager or BlackBerry USB and Modem Drivers. Both are available from the BlackBerry website.

What can JL_Cmder do?
Below is a brief overview of the available commands.

1. deviceinfo - Displays information about the handheld.
2. eventlog - Retrives and displays the handheld event log.
3. screenshot - Takes a picture of the handheld screen. (OS 4.0.2+ required)
4. wipe - Erases the handheld OS. Not really, but that is the simpleist way to explain it. After using the "wipe" command the device will be completely inoperative until the OS is reinstalled. (Error 507 will be displayed on the device)
5. resettofactory - Removes the IT Policy from the device and wipes the device of personal data while leaving the OS installed and usable. (OS 4.3+ required).

NOTE: If you want to use an unlisted JavaLoader command select Command-Line Usage from the menu. This will display JavaLoader help information including syntax and all available commands.

Installation Instructions

1. Download JL_Cmder.
2. Extract executable.
3. Double-click on executable.
   Vista Users: Right-click on executable and select Run As Administrator.

NOTE: Do NOT use JL_Cmder to "wipe" your device if you are just wanting to wipe your personal data from the device and leave it as it was out of the box. If you use the "wipe handheld" option in JL_Cmder your device will be rendered useless (Error 507) until you reload the entire OS. If you just want to wipe your personal data but leave the OS you can use the "wipe handheld" in the Options >Security Options >General Settings Menu on your device or, if your device has OS 4.3 or higher, use the "resettofactory" command in JL_Cmder. The only difference between the "wipe handheld" in the Security Options on the device and "resettofactory" in JL_Cmder is that "resettofactory" also removes the IT policy on 4.3 and higher OS devices.

Do NOT use JL_Cmder to wipe your device if your device is working fine and are simply attempting to upgrade your OS and you can't get the OS to load or be recognized by Desktop Manager or Loader.exe. Doing so will most likely render your device useless until you find the root cause of why the OS will not load to the device. Generally, this is caused by not deleting the vendor.xml file(s) or USB issues with the PC.

It be nice if you either told us what kind of manipulations this will do or better yet if you had some screen shot posted.

The JavaLoader switches it uses are: deviceinfo, eventlog, radio, screenshot, and wipe. For commands that list information from the device JL_Cmder will automatically expor the data into text file for easier reading/modifying. When using the screenshot command all you have to do is type in the name you want to give to the picture. Since the wipe command is a little more dangerous (nukes the device), I added a number of confirmations.

Nothing really fancy, but it gets the job done for me.

I uploaded a new attachment. JL_Cmder does the same thing as before, I just reworded a few things and made it a bit more modular. I also uploaded a screenshot for those who are interested.

Enjoy

Excellent program to take screenshots for documentation. Will be exploring other features as needed. Thanks a lot!!!

Hannah - The screenshot function does not work except for the 7100 and 8700 (guessing) series BlackBerries. This is not a issue with JL_Cmder, but rather with javaloader.exe itself. JavaLoader was not able to capture the screenshot and save it to disk. JL_Cmder does not currently look for the existance of the screenshot, so you see an error when attempting to open a non-exsistent file.
As a work around, you can download the BlackBerry JDE Kit. This will install a number of BB simulators which you can capture screenshots from the simulator itself.

Thank you for your application, I finally got it to work, great neat little app, I had been looking for this for a long time.

(y) Good App. (y)

Uploaded a new version of JL_Cmder. The primary change is the addition of an uninstall option (see thumbnail above). An empty directory is left behind at %ProgramFiles%\JL_Cmder.

Total noob and I'm trying to use JL_Cmder. I'm in the application and try to wipe but all I get is an "unable to open port" message. Any suggestions?

Do you have the handheld software installed on your computer? IS your USb connected directly to the port and not a Hub? It will sometimes not find it on a Hub.

It work perfect on my 7105t, just one suggestion, when capture screenshot, can it be change to jpeg instead of bmp.

Edit" I mean default save as jpeg instead of bmp"

You can do that with photoshop, mspaint or any good graphics program.

That's why I am asking, I am lazy. LOL

Acutally I use the bare bone MS paint and re-save as jpeg.

OK... i'm a real beginner here... what does this program actually do? what do you mean by "screenshot?"

Unfortunatlly no. JavaLoader saves files in BMP format. JL_Cmder is is simply executing the commands built it to JavaLoader. After the screenshot is saved it is automatically opened in whatever application is set to open BMP files. Right now, all you can do is save as into JPG format. I will see if I can come up with something to make this automatic.

Thanks for the program.

Got it figured out. Bad USB cable. Kept losing connectivity. Replaced cable and all is well. Able to wipe and do the 4.1 install without a hitch.

it keeps crashing on my windows xp machine whats wrong?

thanks

Honestly, I don't have any idea what the problem might be. JL_Cmder is a simple batch file that executes JavaLoader command-line options.

I would suggest trying to execute JavaLoader.exe directly (C:\Program Files\JL_Cmder) and see if the problem continues. If it does, then its not my batch file causing the problem. You might want to make sure that your computer is set so that it does not automatically reboot on BSOD. If you get the error message from the BSOD it may help determine the problem.
