LG Nexus 4

Now that Android 4.2.1 has been pushed out to the Nexus 4, and the December bug has been quashed well in time before the month starts, it’s time for Android 4.2.1 based custom ROMs. But hey, why would one want to use anything other than stock Android on a Nexus device, and that too on the latest and the greatest – the LG Nexus 4?

Most Android enthusiasts would agree that there is nothing better than the stock Android experience, and XDA member Geo411m seems to agree. Geo411m has shared a pre-rooted an deodexed ROM based on stock Android 4.2.1 for the Nexus 4, for all to download and enjoy without having to go through the motions of having to root separately after updating to Android 4.2.1.

The stock 4.2.1 ROM, as mentioned earlier is pre-rooted, deodexed and zipaligned, and also includes busybox. So you don’t need to go around hunting for that either. Pure stock Android 4.2.1 experience with root — can’t get better than that. Read on to know how you can install it on your Nexus 4.

Compatibility

This ROM and the guide below are compatible only and only with the LG Nexus 4 smartphone. It’s not compatible with any other device. Check your device model in Settings » About phone.
