1. Thank god, NO! Using the one4all, it`s hacked for good... Changed to Region 0... I even think I moved mine to another house and still didn`t have to hack it again...
2. You use your one4all, typing the code, then play, and "no disc" appears on the player`s screen, then turn it off (using the remote, i guess) wait around 10 seconds, turn it back on, it should be region free.
