Prolific custom ROM developer community AICP (Android Ice Cold Project) has released a new nightly firmware for Motorola's popular mid-range smartphone Moto G (1 Gen) aka Falcon.

AICP's latest 9.0 nightly version is based on AOSP (Android Open Source Project) 5.1.1_r4Lollipop, which is being released for select Nexus devices. It will take a while for Motorola to roll out the firmware. Tech-savvy users who just can't wait for the official software can explore new features of AICP custom ROM on the Moto G.

We would like to remind our readers that the version is unstable and there are some untested bugs that are yet to be fixed.

We advise our readers to go through the whole tutorial article first before going ahead with the installation.

Prerequisites (Things to remember before installing the AICP LP 9.0 Nightly):

  1. Make sure the device is rooted before going ahead with custom ROM installation. [Read more: How to Root Motorola Moto G (Gen 1) with Android 5.0 Lollipop via CF-Auto-Root Tool]
