I use the A.I.D 2.0(advanced auto installer 2.0) all the time on all version xboxes.
It also has all the 007 etc.. softmods to let you get evox running so you can
put the installer disc in. This has everything emulators, apps , modded dash,
bios for chips, and very professional instructions.
I,ve never had any problems and i've done at least fifteen 1.6 consoles.
It's called Auto Installer Deluxe.
If you're going to use this program, then you definitely will need to upgrade to AID 2.1 Final. The 2.0 release was very buggy and causes softmodders major problems if you don't know what you're doing. It was created by a member of a competing site (not really much competition though) so you're not going to get much"tech support" from here if you get stuck.
Your best bet would be to use Krayzie's UXE (or Ndure installer) to do the softmod, then use Slayer's to take care of everything else.
