Well had to repost because the last one had to many errors. Sorry if it screwed up anyones account this is my first time.

Okay so I recently discovered how to mod hex codes with a USB drives (I feel so special)

Modio Tutorial
Well any way onto the tutorial
1.) Change all your armor colors to white (Primary, Secondary, and Detail)
2.) Put your profile onto your USB memory stick
3.) Extract your profile onto your desktop with a USB Explorer program
4.) Open it up in Modio and click "Edit Profile" under your gamer picture
5.) Open the file in there that says 4D5307E6 (Your Halo 3 profile)
6.) Search in the search bar in the bottom right corner of Modio. Search 02 00 00 00 02 00 00 00 02 under HEX
7.) When you find them change all 02 to 1E (Ultra Bright white)
8.) Rehash and resign your profile
9.) Replace the profile on your desktop with the one in the USB Xplorer and put the USB back into your Xbox 360
10.) Finally go on Halo 3 and gloat about your shiny new armor (Color)

Hex Editor Tutorial:
1.) Drag and drop your profile into the hex editor
2.) Search the Hex Code for 02 00 00 00 02 00 00 00 02
3.) Once found change all the 02 to 1E
4.) When done with that save it and replace the profile in the storage device
5.) Put the device back into your Xbox 360 and play Halo 3
6.) Gloat about your new Sexy shiney armor!
