M-ROM is a custom and modified CyanogenMod 11 build based on Android 4.4 KitKat. Use this tutorial if you want to flash such custom ROM for your Google Nexus 4. Note that this is a guide for advanced user who want to test as many KitKat custom ROMs as possible. Make sure to read all the info listed below without skipping any steps.
The CyanogenMod team is currently working on their new Nightlies, the ones that will be based on Android 4.4 KitKat, Google’s latest OS upgrade. The Android 4.4 has been pushed first with the Google Nexus 5, but it will also be released for Nexus 4 and all the other Nexus devices soon. However, until then you can flash custom ROMs and get a taste of KitKat goodies on your Nexus 4.
It would be for the best that you create a full NANDROID Backup for the ROM that is now running on your device. This will set a restore point and it can be used in case the new M-ROM Unofficial CM 11 build features errors or any major bugs.
The following are 100% working: camera, audio, wifi, GPS, Network, SMS, Calling, Notfication lights, Expandable volumes, CyanogenMod profiles, Privacy Guard and Blacklist, Color Calibration, SU and other more. The only thing reported not to be working is the ‘compass’. More info about this custom build can be found in this XDA Thread here.
Before starting the installation, read the preparation guide below:
