Are you looking for a way to install the Android 5.1.1 LYZ28K Lollipop update on your T-Mobile Google Nexus 6? You know that I am always here to support you, so be sure of the fact that I have a guide that suits to your needs as well.

However, I want to be clear from the very beginning about the fact that this Android 5.1.1 LYZ28K Lollipop update tutorial is especially designed for advanced Android users only, so I cannot be blamed if a newbie or any other user bricks his or her GoogleNexus 6 by following the steps that I have mentioned in this tutorial.

I can assure you that all the steps have been tested with the T-Mobile Google Nexus 6 version and that they work, so act responsible and make no mistake of using this post on any other different Nexus 6 models, on skipping or mixing the steps and so on.

Make sure to enable USB Debugging from Developer Options menu; of Developer Options isn’t listed under, then it is your task to enter into Settings> About Phone and tap 7 times on the Build Number section. Return to Settings, scroll down and find the Developer Options; open it right away, find the Developer Options menu and enable the USB Debugging.

Then, don’t forget to download Android SDK from here, install the SDK on your computer and find the SDK Manager executable in order to launch it. You have to install all the SDK packages and usb drivers, then go to the newly created SDK directory and find the ‘platform-tools’ folder. That is where you need to put the Factory Image installation files during the procedure.

Even more, you cannot start the Android 5.1.1 LYZ28K Lollipop update operation if you do not install the USB drivers to your PC so that you can easily connect it to your Google Nexus 6 and make a Nandroid backup for your smartphone as you risk losing all your important data.

Also check your phone’s battery charge level as long as you have to keep at least 60% battery backup on your phone. Otherwise, you risk bricking your T-Mobile Nexus 6 if the device turns down during the update and I am not responsible for that. In fact, the entire tutorial can be applied only under your responsibility, so be very careful and don’t mix things up.
