Motorola has started rolling out the Android 5.0.2 Lollipop update for two of its most popular devices, Moto E from the budget segment and the premium Moto Maxx. However, this is not a full fledged roll out as Motorola follows the soak test pattern with these two devices as well. We’ve recently covered how to install Lollipop 5.0.2 OTA on Moto E and now we’re back with a solid guide for the Moto Maxx as well.

In this guide, we’ll show you how to install Android 5.0.2 Lollipop OTA on your Moto Maxx XT1225 despite the root modifications on your device. Thanks to respider of XDA, you can now install the Lollipop update even if you’re rooted and the best part is you won’t lose your data in the process. However, you’ll be left with a non-rooted Lollipop device at the end of the guide but we suppose it’s a little price to pay at this point. Moreover, you can always root your device by flashing the SuperSU zip from recovery.

Please be warned that this OTA file is not meant for Droid Turbo even though they are different variants of same device. So if you’re ready to jump in, let’s start with the guide.

Prerequisites

  • Charge your battery above 60% to avoid unexpected shutdowns during the process.
  • Either setup ADB and Fastboot on your computer, or download the Minimal Fastboot tool and unzip it: mfastboot-v2.zip (Rename mfastboot.exe to fastboot.exe)
  • Install Motorola USB Drivers on your computer.
  • Enable USB Debugging on your Moto Maxx. If you don’t know how to do it, follow the instructions given here.

    mfastboot.exe flash system system.img_sparsechunk.1
    mfastboot.exe flash system system.img_sparsechunk.2
    mfastboot.exe flash system system.img_sparsechunk.3

Install Android 5.0.2 Lollipop OTA

  3. Open a command prompt in the ADB folder and issue the following command to sideload the OTA file:
    adb sideload Blur_Version.21.11.9.quark_retbr.retbr.en.BR.zip

    Make sure that the OTA file name is matching with the name of the downloaded file.
