The stock firmware of LG G3 is a bit laggy and doesn’t look good because the icon pack and widgets are appalling looking. However, you can install a custom ROM and transform you phone’s interface. Here I have a new good looking custom ROM based on Android 6.0 Marshmallow. Read these Points before installing these custom ROMs on your phone.


Points To Remember:

  • Custom ROM installing is an unofficial operation which may void your device’s warranty.
  • Backup your data before installation of custom ROM so it will not get wiped during installation.
  • Charge your phone to at least 70% before installation of the custom ROM.

Android Marshmallow

In conclusion, that is how to install an unofficial build of Android 6.0 Marshmallow software update on the OnePlus One smartphones by using the Omni ROM custom ROM. It is important to realize the key differences between the stock Rom and a custom version, especially when yo are dealing with custom ROMs that are not as good as the Android developers can create. The Omni Rom is a more than capable team, but they might fall behind the likes of the guys and girls from team CyanogenMod if the were ever to do battle. Therefore, it is important to understand that you do void the warranty agreements by flashing a custom Rom and removing the stock Android version.
