The best method for you to use would be the Syn3 Updater and you want to downgrade and reformat.
Let the application choose the method, do not use forced reformat. You need to downgrade back to 3.3.19052 to run the reformat.
You will want to choose the app, voice, and Gracenotes (if desired), for South America. (ANZ)

This combination with Gracenotes may not fit on your APIM, due to storage restrictions. If the installation fails, remove Gracenotes.
