Flash Official CM 10.2 Nightlies for Google Nexus 4

Update Nexus 4 to Android 4.3 using CM 10.2 Nightlies ROM

CyanogenMod 10.2 Nighlty builds are now available for the Google Nexus 4 smartphone and you can flash the latest build using the tutorial listed below. Make sure to use this post only if you’re an advanced Android user who wants to test the latest releases of CM team along with AOSP Android 4.3 features.

This is not a stable release of CM 10.2, but a Nightly build that’s in its testing phase and you should expect to find some bugs and errors while using it.

In order to make sure that you successfully update your device, you will first need to take a look at the guidelines below. You will learn what you need to do before starting the update. Here’s what you need to do:

  • This guide will work only with the Google Nexus 4 smartphone. Do not attempt to update any other device using the files you find here are you will end up bricking the firmware.
  • Your Nexus 4 has to factory unlocked, rooted and running a custom Recovery.
  • Both CWM and TWRP Recoveries will work with this post.
  • In the ‘how-to’ part of this post you will find a step that asks you to wipe data and factory reset your device. This is required if you’re coming from a different ROM.
    > Note: if you’re already running a previous build of the CM 10.2 Official nightlies, then you can skip this step. But, in case the device doesn’t boot with the new OS, then you simply need to repeat the entire tutorial without skipping the ‘factory reset’ step.
  • The ‘factory reset’ will remove all contents from your device’s system partition. This will delete all installed apps data, SMS etc.
  • To backup SMS, Call Logs info and APN Internet Settings use the following apps for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android application. Root access is needed for some of these apps.
  • Sync your Contacts data with the Gmail account assigned as default on your Nexus 4.
  • The phone’s battery power levels should be over 50% before starting the installation of CM 10.2 Nightlies ROM. If the phone powers off in the middle of the updating process, then you will be forced to repeat the entire tutorial.
  • This is a tutorial for advanced users who want to test the first official CM 10.2 Nightly build for the Nexus 4 along with Android 4.3 AOSP functions.
  • Do not skip any steps listed below.
  • Note that we cannot be blamed in case you brick your device nor in case you lose any important data files during the process.
  • If you cannot complete the update, then you should ask for extra help in comments.

These were all the preparation steps you had to go over before starting the updating process. Read this entire post and note that the Nightlies builds of CM 10.2 might pack some bugs or errors, which is why you should always create a NANDROID backup before installing any new version. Info on how to create NANDROID backup can be found in the tutorial.
