Custom ROMs are a good way to keep older devices with a slower hardware running the newest versions of Android. Here comes the CyanogenMod 10.2, which is a customized ROM based on Android Jelly Bean firmwares. Besides its fancy, simple look, CyanogenMod offers a better performance and reliability of your device. It also provides a lot of new features that are not present in the stock versions of Jelly Bean. Today we’re showing you how to install CM 10.2 Android 4.3 Jelly Bean version on your Google Nexus 4.
Note! This is sort of an alpha version of CM 10.2 so you’ll probable notice some issues or bugs using it. This tutorial is only for the Google Nexus 4. We don’t take responsibility for what’s done to your device. Follow the below steps carefully in order to not brick your device.
