    You could use the autoloader of the OS version to which you want to downgrade. Get the autoloader from this BB10 OS Archive.

    Update: What OS version is installed on your phone? To what OS version do you want to downgrade?

    Do not spread false info. When on 10.3.2 anything 10.3.1 and below is blacklisted.

    You can not back track to any OS prior to the one you have now. It's a PITA, but true.

    More precisely, when on 10.3.2.500 DEV or higher, anything below 10.3.2.500 DEV is blacklisted.

    Uh oh, I don't think 10.3.2.500 allows for downgrading to anything below 10.3.2...
