OmniROM is a brand new project developed by XDA members and developers Xplodwild, Chainfire, Dees_troy. It has been presented at the Big Android BBQ event and it should be ready for an official release soon.

More info about OmniROM can be found at the developers web page here.

This new custom ROM is supposed to become a challenger for CyanogenMod, AOKP, ParanoidAndroid and for all the other popular ROMs. It is still in its ‘work-in-progress’ phase and we should see more and more features added soon.

However, in this post you will find info on how to flash an unofficial build of OmniROM for the Google Nexus 4 smartphone. This unofficial ROM has been bundled together by “#root”, XDA developer. This is a whole new different custom ROM that you should be able to flash in no time without bricking your device.

OmniROM Unofficial #1 custom ROM for Nexus 4 is based on Android 4.3.x Jelly Bean AOSP. Before starting the installation of OmniROM on your device, you should take a look at the guidelines below:

  • Use this post only for the Google Nexus 4 smartphone.
  • Do not attempt to flash the files you find here on any other Android devices, as you will end up bricking their firmwares.
  • The Nexus 4 you’re about to update has to be on an unlocked bootloader and rooted.
    - in case your device’s bootloader is locked, then yo should know that by unlocking it you will lose all data that is currently stored on your phone.
  • The OmniROM has to be flashed using a custom Recovery such as TWRP or CWM. Both variants are working with this tutorial.
  • By installing a brand new custom ROM on your device, you will be forced to apply a factory reset.
    - the factory reset process will remove all contents from your device’s system partition.
    - internal storage won’t be affected by the installation.
  • Backup data from installed applications using one of these two Android apps: Helium (here) or Titanium Backup (here).
  • SMS, Call Logs info and APN Internet Settings can be saved using the following apps: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore. Root access is required for some of these tools.
  • Sync your saved phone numbers and people details with your Gmail account.
    - if you don’t know how to sync contacts data then you can use the info listed here.
  • Create a full NANDROID backup for the ROM that is currently installed on your device.
    - it will set a restore point for your device and you can use it in case your device doesn’t boot with the new OmniROM.
  • Read the entire article first and make sure not to skip any steps listed below.
  • Enable USB Debugging from Developer Options menu.
  • This is a tutorial that should be applied by advanced Android users. You cannot held us responsible in case you brick your device or lose any important data files in the process.
  • Check the Nexus 4 battery charge level and make sure that it’s over 50%. This will prevent it from powering off while you’re flashing the brand new custom ROM.
