A great way to increase armor levels is to use the Health code and leave your character 
attacked for a couple of hours. 

More Cheat Codes
Keep health, magicka, and fatigue levels full
Enable the "Change health level", "Change magicka level", or "Change fatigue level" codes, 
and before you fill your health/magicka/fatigue up, while holding A and filling it, press 
B and exit. It will continue to rise and as it goes down, it will raise back up instantly. 
For example, start filling your health/magicka/fatigue, and press B before it is to the top, 
While still holding A and filling it, it will keep and always be full until you return to 
the menu.
