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 CM 10.1 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 CM 10.1 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.
- If you have any favorite applications or you want to backup and restore SMS after install, Call Logs and the APN Internet Settings, then you should use the following applications for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android application. Note that some of these apps will ask for root access.
- Sync your phone Contacts with your Gmail account.
- Remember to charge your phone’s battery before beginning to flash the new CM 10.1 custom 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.
