Motorola has begun rolling out Android Lollipop for the high-end Moto Maxx with soak test in Brazil and Mexico. The retail unit of Moto Maxx should get the Android Lollipop treatment first via soak test. The upgrade is rolling out to smaller test groups and if everything goes well, Motorola will push out the software to more phones.

If the OTA for soak test has not reached your region, you can install it manually, even if you have rooted you Moto Maxx, using the following installation guide shared by senior XDA member, respider.

Those who have rooted their Moto Maxx and are trying to install the Lollipop OTA (soak test) might get errors due to the modifications to the system. Just removing the SuperSU root file will not be enough, you will have to restore your Motorola phone to stock, advises respider.
