Update Google Nexus 4 E960 to Jelly Bean 4.2.1 with MMuzzy Custom ROM

If you are having hard times in choosing a stable Android 4.2.1 Jelly Bean custom ROM firmware for your LG Google Nexus 4, then this tutorial might be helpful for you, as we will be checking in how to update your phone with the new MMuzzy software. The update is based on the official source build JOP40D, being nothing else but an AOSP ROM which will smoothly run on your Nexus 4 E960 device. So, if I have aroused your attention, then check the next lines and learn how to install the Jelly Bean 4.2.1 powered MMuzzy custom ROM on your Nexus smartphone.

The MMuzzy software has been developed and now released by those of xda-developers so we have them to thanks for this tutorial. The installation procedure is not hard to perform and furthermore, completing the guide will only take a couple of minutes from your free time. Anyway, you should read all the next lines because this is a risky and complex operation and if you somehow mess things up you can even end up in bricking your handset. Don’t worry though as you have all the needed aspects explained and detailed during the present step by step guide.

As mentioned this is an AOSP OS, meaning that there are only minor changes included in the ROM. Anyway, by flashing the same on your Nexus 4 you will customize and optimize the performances, improve the battery life, install new themes, features and capabilities, but the default Android experience will not be changed in a major way. The MMuzzy Jelly Bean 4.2.1 system is rooted and deodexed, but of you want to read more about its capabilities and features I recommend you to check our source page from here.

Of course in order to safely apply the Android 4.2.1 MMuzzy update on your LG Nexus 4 you will first have to perform some preparation tasks. If your device is already prepared (if the steps from below have been previously completed for your phone) for the installation procedure, you can then head straight to the update operation which is being explained below. But now, let’s take care of the pre requisites.

  • You will not be able to complete this tutorial unless a full wipe is applied. This means that all the data which is being saved on the phone’s internal storage memory will be wiped out. Therefore, it will be a good idea to backup the Google Nexus 4 data.
  • It is recommended to make a Nandroid backup too.
  • Root the LG Nexus 4. In this way you will be able to remove the factory restrictions and unchain the internal system as the MMuzzy firmware is requiring access to the same.
  • The warranty will get void, so you will be by yourselves.
  • If you will need to, the warranty can be restored; you just have to downgrade to the stock ROM, or wait for an official software to be released by Google and LG.
  • After rooting, install a custom recovery image on your phone. This tool will be used for applying the wipe and then the update, so completing this step is not an option for you. Take note though as a custom recovery image can be flashed only on a rooted system.

Now your device is being prepared for the installation procedure that will shortly follow. But that’s not all; you still have to ensure that you can use a Windows running computer with internet connection enabled; then enable the USB debugging option on your LG Google Nexus 4 or else you will not be able to connect your device with the computer; deactivate the antivirus and Firewall protection from both, PC and phone; charge the battery of your handset if you notice that there is less than 60% power left; and continue with this tutorial only if you own the Google Nexus 4 model number E960.
