Thanks ldopa! I'll give it a try.
Sometimes it will hang while running the exploit on the 1st try. It's common. If it happens, just pull the battery (it won't hurt don't worry!). Reboot the phone and once it's completely rebooted (give it 3 min or so), run z4 again. It should work within a minute or so (it will run the exploit, reboot and you'll be rooted).
