Install Android L on Nexus 4.
Before following this guide do take the full android backup of your android system. Once the backup process is done, download the Nexus 4 port of Android L here and movie the ZIP file on your phone SD card.
Now boot your device in recovery mode (TWRP or CWM). If you’re using TWRP, tap on Wipe, and on the next screen you’ll be asked if you want to perform a factory reset. Swipe to Factory Reset. Once that is complete, enter the Advanced Wipe menu and tick the Dalvik Cache (wiping twice for good measure) and System checkboxes, then Swipe to Wipe.
Now the next step is to flash the zip file on your nexus 4. Go to the Install option from recovery main menu and select the file that you downloaded to your SD. Now the flashing process will start on your phone.
Once the installation completes successfully, be sure to Wipe Cache/Dalvik one more time. If you are using TWRP, you can do this with one tap from the successful installation screen. Once wiped, reboot your device.
The reboot process will take some time, around 5 to 10 minutes. Now your nexus 4 is running on the Android L OS.
