Just ask any questions you need here about ndure, it is so simple and it is the best
softmod available. Theres plenty of tuts, I'll find you one now.
First read this: (It's alot but you will understand what is happening, you can skip if you really want to.)http://forums.xbox-scene.com/index.php?showtopic=320590
In case you don't know how to get to xbins a.k.a. the usual place:http://www.xbox-scene.com/articles/xbins.php
Ok then basically it boils down to (this is how i did it anyway):
1. Obtain a memory card, controller drivers & usb adaptor
2. Obtain one of the 3 games that are exploitable (splinter cell, mech assault & 007 agent under fire)
3. Download action replay
4. Download krayzies ndure installer 1.1 from xbins
5. Read the krayzie ndure installer 1.1's readme
6. Using action replay transfer the 2 savegames onto the memory card which is plugged into your computer through a controller which is hooked upto usb using the adaptor.
7. Put the memory card into your xbox and copy the 2 savegames over to the xbox. (I ran into problems if there was any other splinter cell savegames on the xbox hard drive.
8. Put the game that matches your gamesave exploit in the xbox and load up the gamesave (which on splinter cell was Start Game -> Load Linux Profile -> Checkpoints.)
9. This will now run krayzies installer which has step by step instructions, everytime u press a button it will popup a message and explain what is happening and tell you what to do.
10. 1st backup your eeprom.
11. Now install softmod.
12. Once softmod is installed it will turn your xbox off, remove disc and power up.
13. Gain FTP access and transfer the files in E:\backups\eeprom\ to a safe place on your computer.
14. transfer any applications you want to your xbox (xbox media center & dvd2xbox i recommend).
