Ha! Yes Caty, i must've still been hungover. Of course a JM unl code will not work with unpatched originals in modern units and fw. You must first change the ID's and then an JM unl code will work. And if you are going to use [Only registered and activated users can see links. ] to change the original id's to FID 700 or 900, PID 1, RID 0, VID 0 ... well, then you may as well just use it to fully unlock them to FID 65535, PID 255, RID 255, VID 0 and just skip the JM unlock .....
In which case you may as well simply use the already unlocked ones from pietu and save yourself any trouble at all.
