Not making this easy. OK, I assume this is a GSM based BlackBerry. You can download the handheld OS from here:
https://www.blackberry.com/Downloads...E4F82F9F00E7D4 - select the 7130c.
- Shut down Desktop Manager
- Download the handheld OS
- Execute the file you just downloaded
- Locate and delete VENDOR.XML on your PC C: drive and delete it
- Connect your BB and restart Desktop Manager
Good luck!
