From a PC, you can install any OS package to a BB via this procedure:
Note that while written for "reload" and the Storm, it can be used to upgrade, downgrade, or reload any BB device model -- it all depends on the OS package you download and install to your PC. You can even use a different carriers OS package by simply inserting, 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!

You have to uninstall from your PC the device OS package...but you can keep the installable file anywhere you like. It's the fact of the OS package being installed into Windows that can create the conflict...the mere existence of the installable file is irrelevant.
As for falling back, as the information says, you can install ANY OS to your BB via the procedure...it all depends on what OS package you have installed into Windows to control what version LOADER.EXE will act upon.
