How to upgrade the Infuse 4G I997 to Android 4.1.1 Jelly Bean

Stop wishfully thinking that Android 4.1.1 Jelly Bean will officially arrive for your Samsung Infuse 4G SGH-I997. It won't.

But, there's another way for your Infuse 4G to run Android 4.1.1 Jelly Bean — through a custom ROM dubbed as CodeName Android. It is based off a clean, stock version of Android 4.1.1 build JRO03L, so you can expect pure stock Android experience with some mix-ins on the side.

Developed by XDA Developers member Th3Bill, the CodeName Android ROM has a lot of customization options you can play with to tune up your Infuse 4G. The ROM works quite well and is quite fast, as reported by some users who tried the ROM.

This guide shows you how to upgrade the Infuse 4G I997 to Android 4.1.1 Jelly Bean via CodeName Android ROM.
