CAn some1 help with this problem...im trying to fix my BB8100 but it's still not working. I have visited some site that gave me idea on how to fix it kindly give me a comment on whats wrong about the steps. Thank you
1. Download and install Jl_Cmder to your PC ( Click here to download Jl_Cmder ) Reference Link
2. Make sure ALL your data (i.e. contacts, appointments, memos and etc) are backed up or synced before proceeding! This will wipe everything off of the device
3. Make sure you have the latest version of both Desktop Manager and the Handheld OS installed on your PC. If you need them then download them from here:
Desktop Manager and Handheld OS List
4. From the PC navigate to c:\program files\common files\research in motion\apploader and delete the file vendor.xml
If you have never installed the Handheld OS before then the vendor.xml file will not be on the PC and you can skip this step
5. Plug the device into the PC using the USB cord and make sure Desktop Manager is closed
6. Remove the battery from the device
