A new Android OS ROM series has been released to Motorola's popular 2013 mid-range smartphone Moto G.

This new ROM is created by senior XDA Developer forum member, who goes by the moniker Alberto97. Based on the latest AOSP (Android Open Source Project) v5.1.1 Lollipop, this is the pure-stock (vanilla) firmware that is being released in phases to Nexus devices.

In order to make it more user-friendly, Alberto97 has borrowed some tweaks from CodeAurora Forum and CyanogenMod to the AOSP ROM. He has also incorporated three options namely, 'Advanced Reboot, 'Clear All' button in 'Recents', and an option to delete screenshots from the notification area.

We would like to remind our readers that this is an experimental version, so some issues are yet to be fixed. We advise our readers to go through the whole tutorial article before going ahead with the installation.

Features of AOSP ROM that are said to be functional on Motorola Moto G (Gen 1):

  • RIL [Radio Interface Layer]
  • WiFi
  • Bluetooth
  • Audio
  • Mobile Data
  • Offline Charge
  • MTP [Media Transfer Protocol]
  • Hotspot WiFi

Prerequisites (things to remember before installing Custom ROM)

  • This AOSP Android 5.1.1 Lollipop ROM can be installed on Moto G (Gen 1) Single-SIM models only [More information, HERE]; 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.
  • 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 device (Moto G) will not be recognized by the computer.
  • Make sure your device has more than 80 percent battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted in the 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].
