So, be patience, read all the lines from here and make sure that you have applied all that is being detailed during the following list of tasks.

  • Start by backing up the data. A full wipe of the system will be required therefore it is essential to save your personal if whether it is about the contacts, messages, call, logs or market apps. For that and fore easing your work, use our search engine and look over our how to section for suitable backup and restore step by step guides.
  • When you first buy your handset it will be delivered with a locked bootloader. Now, for being able to install a custom ROM on your Nexus 4 you must unlock the bootloader. For learning more about this concept and also for learning how to unlock it, use the link from above.
  • Also, the system of your phone must be unchained from the factory restrictions and unlocking the bootloader is not enough. Therefore you must also root the Google Nexus 4 before updating it.
  • Be aware as the warranty will get void once you apply the above described operations. The only way from which you can restore the warranty will be by downgrading to the stock ROM or by updating with an official firmware released by Google.
  • After unlocking the bootloader and after rooting the system, you must download and install a custom recovery image, like CWM recovery, on your device. This is a complex tool which will be used for the flashing process (we will talk more about this during the proper steps).
  • For the installation procedure, you need to have access to a Windows powered computer, to your phone and to its USB cord.
  • On the handset the USB debugging option must be enabled.
  • On the PC and smartphone there shouldn’t be running or installed any security tools (I’m referring to the antivirus program and to the Firewall protection).
  • Furthermore, check the battery status on your Nexus 4. If there is less than 50% power left, charge your phone before heading to the steps from below.
  • Apply this tutorial only if you have the LG Google Nexus 4 because the guide can’t be used for updating a similar device with the Android 4.2 Jelly Time custom ROM.
