Prolific mobile software developer CyanogenMod team has released new Android v4.4.4 KitKat CM11 M12 milestone series custom ROM to the LG's 2012 flagship Google Nexus 4 model.

The CM11 M12 series custom ROM is based on the AOSP (Android Open Source Project) v4.4.4 KitKat OS and brings enhancements to battery life, performance and also fixes the POODLE vulnerability found in SSL (Secure Socket Layer) v3 protocol of most of the Internet browsers. [More information, HERE]

Prerequisites (things to remember before installing Custom ROM):

  • Though installing custom ROM improve the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].
  • Make sure the device is rooted before going forward for custom ROM installation [Also read: Root Google Nexus 4 with Android v4.4.4 KitKat KTU84P]
  • This new CM11 M12s series custom ROM has to be installed on the LG-Google Nexus 4 (aka Mako) only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number].
  • Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
  • Users make sure they have installed USB drivers on the PC, or else your phone (Google Nexus 4) smartphone will not be recognised by the computer.
  • Make sure your device has more than 80%, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted mid-way.
