- Delete "Research In Motion" folder , again.
- Go One step back to "AppData" then Go to "Local" and search again for "Research In Motion" folder, Delete it!.
- We need to make sure that after uninstalling "BlackberryDeviceManager" from the Program Installed Lists, All Programs that are related to Blackberry should also be uninstalled. "Blacberry Device Manager Software Updater" should also be uninstalled.
- Now, RESTART your computer.
- Then , INSTALL again the BDM. (There should be NO BLACKBERRY DEVICE CONNECTED, Take Note!) , Restart computer after the installation process. DELETE Vendor.xml (Program Files>Common Files>Research In Motion>AppLoader)
- Install the "blackberry bold device software OS 7.1" (it can be be downloaded online) so that we can bypass the Error of Getting "it is only available for Blackberry users subscribed to blackberry subscription service" from usual BDM update.

STEP-BY-STEP Process to Unbrick Your Nuked/Bricked Blackberry Bold 9900

- Create a new USER ACCOUNT (It should be Administrator) , then Log off and Login to your new Admin user Account.
- Connect your Blackberry Device, Wait until the "device driver installation process" completes.
- Open BDM , Wait til your device being detected. There will be a window that will Pop-up letting you choose whether to "Repair , Update or just Cancel" , Just choose or Click the "update" button.
- After clicking the Update button, Just wait for a few moment, until a new window pop-up again saying that you're now going to install an update and should not be interrupted by just disconnecting or unplugging your usb cable, click the "Install Update" button there.
- Now , A new window will pop-up again and for this time , You're in the process of loading the OS 7.1 into your device.
- In the part of "Install" process , if you encounter problem in the middle of "Reconnecting JVM" process and AppLoader Unable to Connect to your blackberry device, Just Click "retry" (do not disconnect or unplug the cable uh) , if it still persist, just retry and retry , do it 3x . and if it didn't work and the error window is still there, Do not click "retry'' , just leave it there for a moment and try to PULL OUT YOUR BATTERY while your device is connected to the computer , then PUT IT BACK and click "Retry" , your device will now boot-up and will continue until the process of loading OS 7.1 is done. and the last process would be "REBOOT" , your device will restart and wait until the device boot-up. it would take a few minutes. So be patient.

I didn't use AppLoader alone, itself, to install or load the OS , Cause if your "USB-PIN" becomes "USB-PIN: UNKNOWN" , it would be 70%-30% chances. 70% that your device won't be able to undergo the whole process of Loading/Updating OS 7.1 , 30% chances that your device might be successfully recovered. No man is an Island - Apploader LOL

Now , Your Blackberry Bold 9900 is unbricked!
The only problem is your attitude towards the problem
