if you backed it up before this problem hard reset and do a system restore using the BB desktop. I've made the same mistake on my old BB, not sure if this will work with the 4.0 OS.

If there is a backup in the system it will work I have done it already once. Though hope to not have to again, scarred the dickens out of me when it locked up.

Could always use the javaloader.exe

1) Connect your BlackBerry, open a DOS prompt and type
javaloader -usb wipe

2) Make sure you have the latest version of your handheld's Operating System. See the sticky thread on top for links to every carrier's version of the handheld OS. Download and install

3) Restart Desktop Manager. The OS should now reload.

See the thread maked blackberry 4.0 software, You need the desktop and the handheld software. Once connected it will pretty much self-repair.

I had same issue this worked also search for JL_cmdr might need to use that to wipe the BB clean then reinstall software I have a post DEAD Blackberry with the instructions from another BB operator These guys are great here!!!!

You can try to recover your device using this procedure:

1. Install Desktop Manager (You can skip this if it is already installed)
2. Install firmware package for your device on your pc (You can skip this if it is already installed)
3. Make sure Desktop Manager is not running
4. Start loader.exe for C:\Program Files\Common Files\Research in Motion\AppLoader
5. Click on Next in the Application Loader window
6. Remove the battery from your BB
7. Connect your BB to the USB cable
8. Reinsert the battery
9. The drop down list "Connection:" should now change from COM1 to either USB:UNKNOWN or USB:[BBPIN]. As soon as you see "USB:..." click on Next and Application loader should be able to reconnect to your device. Now you can reload the firmware.

As timing is important for this procedure, it can be possible that you have to repeat the procedure multiple times until you succeed. Good luck!
