The new build of the CyanogenMod 10.1 for Nexus 4 that is based on the Android 4.2 Jelly Bean, has been released. Use all the instructions that I’ve listed in this post and you’ll learn how to successfully flash the new ROM on your device. Read the entire post and use this tutorial only if you’re an advanced user.
It is based on the Android 4.2 Jelly Bean and now you can easily flash it on your Nexus 4. Before you can begin to install the new update files, you need to read the pre-requisites guide first and learn what you had to do. These extra steps will make sure that you flash the CM10.1 Official Nightlies for Google Nexus 4 successfully:
Install the ROM only on the Google Nexus 4 aka ‘mako’ smartphone. Do not try to flash the files you find in this post on any other Android phone or tablet.
The Nexus 4 should be on an unlocked bootrom, it should be rooted and running CWM Recovery. If your phone doesn’t have these then you cannot complete the ROM installation.
Create a full NANDROID backup of your currently installed ROM. This file will be very useful in case you cannot use the phone after installing CyanogenMod 10.1 Nightlies. However, you shouldn’t worry as your device doesn’t brick that easy.
Remember to charge your phone’s battery before beginning to flash the new ROM.
Enable USB Debugging option from the Developer Options menu. NOTE: The Developer Option are now hidden and in order to make them visible you need to open Settings, then press the ‘About Phone’ menu. Now you have to press the ‘Build Number’ section 7 times until you receive the ‘You are now a developer’ message.
Note that we cannot be held responsible in case your device gets bricked in the process. Also, we cannot be blamed if you lose any apps or any other type of data files. Install this new ROM at your own risk.
Read all the info I’ve listed and make sure that you don’t skip any steps.

How to install Official CyanogenMod 10.1 Nightlies on Google Nexus 4:
Download the CM10.1 Nightly build from HERE. Save the file on your computer’s desktop screen. Don’t unzip its files.
Get the Gapps for Jelly Bean 4.2 file from HERE. Proceed just you did with the ROM file and don’t extract the zip contents.
Connect your smartphone to your PC using the USB cable. Now move both files on the internal SD card storage. Disconnect the N4 device from computer when the files are successfully copied.
Power off your Nexus 4 completely.
Boot into Bootloader Mode by pressing ‘Volume Down’ and ‘Power’ buttons at the same time. Release the buttons when the N4 display powers on and you see the ‘Start’ text. Highlight ‘Recovery mode’ option and then press again Power to boot into CWM Recovery mode.
First thing that you need to do in ClockworkMod Recovery is to wipe the data. For this you need to select ‘wipe data/ factory reset’ and confirm the process.
Now, select ‘install zip from sdcard’ and from the new selection screen ‘choose zip from sdcard’. Browse for the CM10.1 Nightly zip file and confirm that you want to install it.
When the custom ROM is installed you should select again’ choose zip from sdcard’. Now you need to flash the Gapps file for ‘mako’. Confirm.
After the CM10.1 ROM and the Google Apps files are installed you have to return to the main custom recovery screen.
Select ‘reboot system now’ and wait at least 5 minutes for the boot menu to load its new CyanogenMod 10.1 – Android 4.2 home screen.
Use your Google Account details to take control over your smartphone.
Test the new Jelly Bean features and tell us in comments if you like the new CM10.1 Nightlies ROM.
These were all the steps you had to take in order to update your Nexus 4. In case you cannot flash the ROM files at your first attempt, then you try to re-apply all the tutorial steps once again and, eventually, you should be able to boot the new CM10.1 custom ROM.
