LG decided to update it’s flagship devices to Android 5.0 and LG G3 D855 was one of those devices. In Android 5.0 are found some bugs that were fixed on Android 5.1.

So for now there is only the early build of CyanogenMod 12.1. If you want to test Android 5.1 on LG G3 you have to install this build.

Note: I shall not held responsible for any damage caused to your phone during and after flashing the ROM. Here at DoryLabs we only provide the guide but only you can decide to go further and install CyanogenMod 12.1 Lollipop 5.1 on LG G3 D855.

Getting Things Ready

• The CyanogenMod 12.1 Custom ROM you are going to find here will work only on LG G3 D855. Don’t flash it on other phones because it will result in bricking the device. Go to Settings > About Phone and check your device Model Number.
• Always make a backup before installing a Custom ROM. In case something goes wrong you still can access your data and restore them in immediately. I reccomend you to do a Nanadroid backup because it will make a full copy of your system and files.
• Make sure your LG G3 is charged more than 60%. If not then charge it so your phone will not turn off during the installation process.

Requirements

• Root access. Ensure that your LG G3 is rooted and then proceed at the installation of CyanogenMod 12.1 ROM.
• install a Custom Recovery. It will be needed to flash the ROM file. Every Android device has a recovery installed by default but it doesn’t allow you to perform many actions.
