How to upgrade the myTouch 4G to Android 4.1.1 Jelly Bean

The T-Mobile HTC myTouch 4G came to the market two years ago, armed with a 1 GHz Scorpion processor, a 3.8-inch display, and Android 2.2 Froyo. The device was upgradable to Gingerbread but who would've thought that the device could be upgraded to the fastest OS to date — Android 4.1.1 Jelly Bean.

Jelly Bean custom ROMs are available for the HTC myTouch 4G and today, we will be showing you how to install yet another Jelly Bean-based custom ROM called Codename Android. Codename Android ROMs are based on pure stock Android 4.1.1 Jelly Bean, dedicated to making you feel like you are using a stock Android OS and not a custom ROM. A smooth as butter interface, Google Now, and advanced search functionality are some of the things you can expect to see when you install this ROM.

Codename Android also features extensive customization options that allow you to modify the interface. You can also customize the theme using the ROM's theme engine that also houses a number of different themes.

This guide shows you how to upgrade the myTouch 4G to Android 4.1.1 Jelly Bean via Codename Android custom ROM.
