Hi and Welcome to the Forums!
From a PC, you can install any OS package to a BB via this procedure:
Note that while written for "reload", it can be used to upgrade, downgrade, or reload -- it all depends on the OS package you download and install to your PC. In your case, I would advise that you treat each OS install as if you are using a different carriers OS package -- insert, between steps 1 and 2, the deletion, on your PC, of a file named VENDOR.XML. Be sure that you remove, from your PC, any other BB device OS packages as having more than one installed to the PC can cause conflicts with this procedure.
If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:
Good luck and let us know!
