Too bad it's an outdated ROM. I would love to see the newest MIUI ROM running on this beauty, but I'm too scared to try it out and mess it up, and then risking to lose the DRM key.
Edit: Are there any good ROMS with nice GUI apart from Sony's UI for the Xperia Z? The MIUI ROM V5 is based on Android 4.2.2, which is more a downgrade than an upgrade...
There are many good ROMs on the forum.
Actually, UI varies from person to person so it's very difficult to say which one is better, you can search in the forum and find a suitable one.
As for me, I highly recommend PA which include many good features.
Sorry for my bad English
