When you load your backup under TX OS, remember that the game will remain in your library of played games.
If TX SX doesn't support network connection, all you'll have to do is boot normal firmware, press + on the played game (which will show ejected, but on your home screen) and download update.
I am 100% sure this will be doable , if you won't be able to update under cfw mode
