u have to go to a check point so it saves automatically for you....calm down and use some common sense...this is not bran surgery, ur jsut over thinking it bro....for reals

look start up a game on the 3rd mission. save and quit. take out hardrive and mod it. then put hard drive back in. start up the game. then go to solo campaign, then press resume game, play for 3 secs, then save and quit, and then go to solo campaign and and start up nazi zombies.

Do u have Teamviewer ill help u

Alright.
"Resume Game" Is there now, and as soon as possible, I save and quit. Then I go to solo;Nazi Zombies;Der Riese, and Everything is normal!
And All of this is done with my Ethernet cord completely out of my xbox.
I've also tried going to Nazi Zombies straight from the game menu.

Alright. All the mods work. but just for one game of zombies, and then I have to remod.
But thanks HEATHbar, your directions were right.
