• UDE2
  • Works on every single official Xbox kernel released to date, up to and including 5838 (version 1.6 Xboxes).
  • Considered dangerous to install, because this modifies to boot sequence.
    • What works on one Xbox may not work on another!
    Some files are dependant on the kernel being used. I myself, in a spirit of being cautious, would not trust a successful experience on one Xbox to definitely mean that installation on another Xbox will occur without incident.
    • I have personally installed this on a K4817D4920 system without incident. This was later uninstalled without incident so the another hack could be tested, and it was not re-installed because the non-direct-booting of EEE was preferred.
  • It seems that ldots's UDE(2) (Un)Installation package is fairly widely recommended method of installing this.
    • Although I generally recommend against using packages, I have seen more than one report from people of trouble installing UDE/UDE2. (It may be user error, or it may have been due to earlier versions of the hack.) If you don't know what you're doing, the wisest thing to do would be to use his package. Don't blame me if something doesn't work, though!
    • This package contains binaries made with Microsoft's XDK, and can be found in /XBOX/Operating Systems/linux/distributions/ltools of "The Usual Places".
    • Be sure to read ltools's documentation, the first thing linked to on Angerwound's list of Exploit Tools links
• I don't know that this version number is really meant to suggest that this is far superior to UDE, but rather that this is simply a different version because it is based on a different XBE file, and it is newer.
  • Based on "NFL Fever 2003"'s UPDATE.XBE file.

Installation:

I installed by following the directions from UDE2 updatefonts70.zip's ReadMe.txt. The following steps are basically taken from that file.

• First, if using a kernel older than 5713, I recommend installing the Easter Egg Exploit, because it is a safer-to-install hack and it doesn't interfere with UDE2 at all. However, one cannot test the Easter Egg Exploit from an unhacked state so easily after UDE2 is installed. So that you can comfortable always know you have that extra hack in the backup, I recommend installed EEE and testing it before any installation of UDE2.
• Go to UDE2's home page, a forum post on X-S and grab the latest version which, as of this writing, is the updatefonts70.zip file.
• Obtain a copy of update.xbe from one of the versions of MS Dashboard 4920.
  • update.xbe from Dash 4920 with directory xboxdashdata.10027100
    • file size 1,914,880
    • md5sum 73402a42463766842e56e82b839d5669.
    • only works with kernels 5530 and less.
  • update.xbe from Dash 4920 with directory xboxdashdata.1012A700
    • file size 1,974,272
    • md5sum 8ab653c39f555758fb65d9014928c4cd
    • only works with kernels 5530 and less.
  • update.xbe from the "Xbox Live!" content of the game "NFL Fever 2003"
    • file size 1,916,928
    • b2875da022264e19107db4fb1f7af1db
    • (works with all kernels (3944-5838))
    • only for US/CANADA region
      • EEPROM can be changed for Xboxes which are not North American
      • but Config Magic FINAL doesn't work on Xboxes with version 1.6 of motherboard
    • This executable can be made using /XBOX/exploits/Font_Exploits/UDE2/s1916928.zip from "The Usual Places"
      • This file is larger and different than the s1916928.zip pointed to by UDE2's webpage.
• Rename C:\xboxdash.xbe to C:\msxboxdash.xbe
• Copy the update.xbe file (from Dash 4920 or "NFL Fever 2003" to the Xbox hard drive and rename it to C:\xboxdash.xbe
• Rename the C:\fonts\ directory (to anything that doesn't already exist there).
  • From what I can tell this is completely unnecessary, but a common alternate name used is C:\f0nts, using a zero instead of the letter "o".
• Make a brand new, empty directory called C:\fonts\
• Decide what bert.xtf file you are going to use
  • See step five in the directions of the UDE2 updatefonts70.zip.
  • Select according to the kernel version of the Xbox
• Copy the bert file to C:\fonts\. If you are using a kernel-specific version of bert.xtf (which should be done if a kernel-specific version of bert.xtf exists for the kernel), this should be the first file placed into C:\fonts\ so that it is the first file in the FATX file system's directory listing for the C:\fonts\ folder.
• Copy ernie.xtf to C:\fonts\
• Put a habibi-signed executable at E:\default.xbe
  • My recommended setup: Put XSelect 0.9 in E:\default.xbe, and have it run the programs according to my Startup Sequence for Hacks.
  • If XSelect 0.9 successfully runs after rebooting, and there are troubles after that point, I can know that UDE2 is not at fault because it is properly installed. Simply knowing this can help to fix whatever other troubles exist: What troubles may exist at this point should be fairly painless to resolve (at least with an expert's help).
• I then re-check everything to my satisfaction, to make sure I followed all the directions properly.
• I then turn the power off on the Xbox. (The "Reboot" option in some Xbox software may be affected by an alternate BIOS. I doubt that most IGR's would be sufficient.)
• I then follow step 9 in updatefonts70.zip's ReadMe.txt, which is "Reboot. Your box should now run E:\default.xbe automatically." By "rebooting", at this point, I simply mean I turn the Xbox on, making sure there is not a game disc in the drive.
• If E:\default.xbe doesn't run correctly There are further steps in updatefonts70.zip's ReadMe.Txt in case things do not work as hoped. And it worked successfully for me. If it doesn't for you, read the steps after step 9 in updatefonts70.zip's Readme.txt.

The hack's homepage is on a forum post on X-S. In my successful installation, I grabbed the updatefonts70.zip and followed the readme.txt file very carefully.
