And JC, you told me to "2. Wipe with JL_Cmder
3. Download and install the OS package to the PC.
4. Delete vendor.xml file located in c:\program files\common files\research in motion\apploader"
But on this wiki page, How do I wipe the BlackBerry using Jl Cmder? - BlackBerryFAQ
it's telling me to "4. From the PC navigate to c:\program files\common files\research in motion\apploader and delete the file vendor.xml
a) 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 "
and THEN run the wipe. Which one do I do first?
