4) Wait for a few seconds till you get the confirmation that it was done.
5) Now your device has no operating system and you should see a white screen on the BB

7) Install the *.exe file you just downloaded.
8) Navigate to My Computer >>> C: >>> Program Files >>> Common Files >>> Research in Motion >>> Apploader
If you have 64-bit version Windows then Navigate to Computer >>> C: >>> Program Files(x86) >>> Common Files >>> Research in Motion >>> Apploader
9) Delete the file named vendor.xml
11) Run loader.exe from that same folder then proceed to installing your OS.
12) Follow the on-screen instructions and enjoy. (Incase you were given 2 choices whether to leave the applications intact or to downgrade them to the original versions, choose the 2nd option which is to downgrade them, this will ensure you have a completely fresh installation)
13) Restore the Backup taken earlier back via DM. It is recommended to restore only those data which are required like SMS, Call Logs, Mails, Contacts etc.
