The latest Moto series Android devices have conquered the smartphone market, covering every factor that controls the aspects of any smartphone’s success. They are fast, more battery efficient and deliver optimum performance, but all this in a very reasonable price. Moto has also been successful in delivering latest firmware updates to its devices, which not only includes the mid-range Moto X or Moto G, but also the Moto E.

Also, Android Lollipop has been a huge turnover, which brings in various improvements and new features, with a more simple and beautiful Material Design interface. Lately, a new update – Android Lollipop 5.1 has been released which has already been pushed to the Nexus devices. We have also covered a detailed overview of Android Lollipop 5.1. Motorola on the other hand, has also planned to deliver its flagships with this new update, which would definitely take a decent time period. But then, not everyone of us is that patient to wait for the update to arrive on our device officially and hence, we make use of custom ROMs, which provides us with the taste of latest firmware.

Moto G is Motorola’s mid-range Android smartphone which has seen a lot of success in several countries over November 2013. It comprises of a 4.5 inches Gorilla Glass IPS LCD display, a powerful Snapdragon 400 1.2 GHz Quad-core processor, 1 GB RAM, and Adreno 305 GPU, and comes in a 8GB and 16GB variant. The device runs on JellyBean 4.3 out-of-the-box and is eligible for the Lollipop 5.0 upgrade, officially. But today, we will update the Moto G 2013 to Android Lollipop 5.1 using a custom ROM.

About ROM

The ROM has been compiled and maintained by Alberto97 (Senior member @XDA). The best thing about the ROM is its untouched and complete stock behavior. It has been compiled directly from AOSP Lollipop 5.1 code with no added modifications. The developer has also pulled some commits from CyanogenMod and CAF to make this work on the Moto G. Apart from this, three specific minor features have also been added – Clear All button, Advanced Reboot menu, and option to delete screenshots directly from the Notification area. Note that the ROM is not rooted, but you can flash SuperSU to gain that.

Working features:

  • RIL
  • WiFi
  • Bluetooth
  • Audio
  • Mobile Data
  • Offline Charge
  • USB OTG
  • MTP
  • Hotspot WiFi

Only a few minor things are yet to be worked on, this includes no support of dual SIM and CDMA variant, and also the stock SMS app cannot send SMS. While you can send SMS using 3rd party apps like Messenger, 8SMS etc. AOSP ROM has only been released a while back but it has been already claimed to be stable and working flawlessly by users. If you’re a developer, you can give a look over to the ROM source code
