Another day, more jelly beans. We’ve already seen the release of a couple of custom Jelly Bean Android 4.1 ROMs for the HTC myTouch 4G, and now owners of the device can try out another ROM – Codename Android.

Codename Android is based on pure stock Android 4.1 and features blazing fast performance, and also includes a myriad of customization options that allow you to change different parts of the interface, including a theme engine with lots of different themes available. Jelly Bean itself brings many new features such as a butter smooth interface, actionable and expandable notifications, Google Now and advanced Search functionality, and more.

This ROM is not an official HTC ROM, and is a custom ROM that has a few issues present. As of 27-8-2012, the following things do not work in the ROM (the most updated issues list can be found on the source page):

Front Camera

LED (Only Charging)

Wifi Hotspot – use WiFi tether app (on play store). in settings, make device ‘NexusOne’ and enable the ‘Routing Fix’

How to Install Codename Android ROM on myTouch 4G

  1. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    NOTE: Don’t forget to at least note down your network’s APN settings, which are required to make mobile data work. Go into Settings » More » Mobile Networks, click on the APN that is in use, then note down the setting for each field. While APN settings should be automatically restored from network, you can enter them manually if needed to make mobile data work. You can also find your APN details → here.
