A new CyanogenMod Android 5.0.2 Lollipop CM12 custom ROM has been released to LG's 2012 flagship smartphone Google Nexus 4.

This new custom ROM has been developed by XDA Developer Forum's recognised senior member going by the moniker, 'AndroGeek974'. Other contributors include myfluxi, fattire and iammuze.

It is 241MB in size and this firmware is based on the AOSP (Android Open Source Project) 5.0.2 Lollipop.

This is an experimental Beta CM12 (unstable) version, so some issues are yet to be fixed. We advise our readers go through the whole tutorial article first before going ahead with the custom ROM installation.

Prerequisites (things to remember before installing Custom ROM):

  • This new CM12 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]
  • 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]
  • 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.
  • Make sure to install USB drivers on the PC, or else your smartphone (Google Nexus 4) will not be recognised by the computer.
  • Make sure your device has more than 80% battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted mid-way.
  • Though installing custom ROM improves 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].

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. International Business Times, India Edition cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked. Hence, users are advised to proceed with caution.]
