How to install CM 12.1 Android 5.1.1 Stable ROM on Nexus 4:

As always, before we get to the actual steps, there are a few prerequisites that you need to take care of.

  • Create a backup of your data for when you run into some problem during the process.
  • Make sure that your Nexus 4 has at least 80% of battery life.
  • Your device should be rooted using the most recent recovery system installed.
  • Its bootloader should be unlocked.
  • Make sure to enable USB Debugging on your Nexus 4.

Required files: download CM 12.1 Android 5.1.1 custom ROM for Nexus 4. Also download Gapps from here. 

Step 1:

Connect your Nexus 4 to your PC using USB cable and copy the downloaded files to the internal storage of your device. Power off your device and unplug from the computer.

Step 2:

Boot your Nexus 4 to Custom Recovery mode: press and hold PowerVolume Up and Volume Down button. Release them when you see the Bootloader or Fastboot menu. You will see the Start button on the screen, use Volume Up and Down until it highlights the Recovery Mode. Press Power button to enter Recovery.

Step 3:

Select Backup and Restore to perform Nandroid Backup and then go back to main menu. Next, you must wipe data by selecting wipe data/factory reset. Also, wipe cache partition to perform cache wipe. Finally, Delvik Cache should also be wiped from Advanced > Wipe Delvik Cache.

Step 4:

Now, select Install zip from sdcard > choose zip from sdcard from the main recovery menu. Locate the Stable CM 12.1 Android 5.1.1 custom ROM for Nexus 4. Select and confirm.

Step 5:

When the Stable CM 12.1 custom ROM is flashed, use the same method to install GApps. After you are done, select reboot system now to perform a normal boot. It will take some time to load all files as this is the first boot after flashing.
