How to upgrade the Infuse 4G I997 to Android 4.1.1 Jelly Bean via MIUI.us ROM

The Samsung Infuse 4G SGH-I997 was Samsung’s thinnest smartphone back then at only 8.99 mm. The phone was easy to slide in and out of pockets and it became one of the popular phones because of its power, aside from its thinness. It has been more than a year since the release of this phone and I bet some owners are still keeping in pace with the rest of the world as they upgrade their phone’s OS from Froyo to Gingerbread to Ice Cream Sandwich. But, what about Jelly Bean?
In today’s guide, your Samsung Infuse 4G will be able to bask in all the goodness of Jelly Bean via a custom ROM — the MIUI.us ROM. Released by XDA Developers member Th3Bill, this MIUI.us ROM is based on CyanogenMod 10 with Jelly Bean features mixed in. The ROM is still in constant development and noticeable lags and jitters are also present.
This guide shows you how to upgrade the Infuse 4G I997 to Android 4.1.1 Jelly Bean via MIUI.us ROM.
