In order to make sure that you successfully flash the AOKP JB-MR1 build3 on your Nexus 4, read the guidelines below:

  • This is a guide that will work only with the LG / Google Nexus 4 ‘mako’ smartphone. Don’t use this tutorial any other Android device as you will end up bricking it.
  • Use this tutorial only if your device is on unlocked bootloader, rooted and running a custom Recovery image such as TWRP or CWM.
  • You should use the custom Recovery mode to create a NANDROID backup of the currently installed ROM. This will be your cover in case the phone doesn’t boot after installing the new ROM.
  • Move all your important files to your phone’s internal SDcard.
  • If you want to backup SMS, Call Logs and some other data, use these tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android application. The tutorial contains a step that will ask you to factory reset the device, it will delete the system partition and not the internal SD card. NOTE: if your device is already on an AOKP JB ROM then you can flash this custom ROM over it without ‘factory reset’.
  • Also, sync your Gmail with the Contacts / People app. It will save all phone numbers and other data from your device.
  • Enable USB debugging option for your smartphone.
  • The battery of your device should be charged and showing that at least 50% power is left before powering down.
  • We cannot be held responsible if you brick the Nexus or in case you lose important files. Read the entire post and don’t skip any steps listed below.
  • If you cannot complete the installation, then you should leave a detailed comment at the end of this post and we will try to offer you a solution to your problems.

These were all the guidelines that you had to read before getting to the tutorial. Now you should read the rest of this post and learn how to flash the official Android Open Kang Project build #3 of Monthly Release ROM on your Mako phone.
