Once you edit the .xex file the signature is broken, it won't boot.
Dev units will boot unsigned code, a retail unit can't boot a .xex unless it's signed by M$. So for a dev to create something before it can even run on a stock console it has to go through M$'s signing process.
You guys can forget about editing the .xex files, they are all signed.
Well here is something that you may nto know. You obviously just read this stuff and dotn try any of it. I have been workign with not just hdd fiels and game saves but with the actual game fiels on the discs. Here is what I know.
Signature files DO NOT become corrupt once viewed or edited as long as you dont edit the actual signature in the file. Usually these are very obviouse so they are not hard to find. However you are partially right in one way. When I first started workign aroudn saved game files I started with full auto and hitman and moved to Gears of war and lost planet. When I got done with all of this I threw them on my HDD and tyred to play them. Now when I got to the point of playign the game some woudl not even load to the main menu and others would not load past the main menu. They woudl all come up with a unreadable disc error.
I worked for a while t find away around this and finally found a back door. My friend posted it for me n other sites btu here you go:
If you want to edit any files on the Hdd includeing the XEX filesfirst copy everythign from the cache and content folders. Delete all the game updates from the 000000000000 Folder. Hell delete the folder. The games wil not load if the updates are still there, somethign with a signature when formatting. Now hook the drive back to the 360 and reformat it. Make sure you are not online and no cable is conected. you do not want any updates downloading on you. Make sure all game discs are out of the system.
Now edit what files you want and put them where they belong. Then transfer all the hdd data back to the drive.
Load up your 360 with the hdd back on it and connect to xbox live. You shouls get a message sayign soemone else has egistered this profile on another console so you will have to go and restore gamertag.
You are now ready to play. Most signature Files will do this to your system such as gamesaves and xex files. I can edit my wallpapers and themes no problem but any main files and well gotta do this.
I promise this works just fine I have sone this with most any fiel type around. If you are stil getting a disc read error then try again. You did somethign wrong or deleted part of the signature inside the file.
Also your signature for your gamertag is inside your gamertag file. just compare the starting hex with a gamesave and find wher it becomes different and there you have it. that is how to edit save fiels to work with your profile from someone elses
sorry for the spelling you must understand its liek 5am here and its been a long day.
