Without checking all the guidelines from this guide you can easily end up in bricking your Android device, so be careful and try not to mess things up in any matter.

Start by making a Nandroid backup in order to save the firmware that is now running on your phone. Having and using a Nandroid backup is great especially if CM 12 will not be on your taste, or if the Android 5.0.1 Lollipop OS will come with bugs and with other software related issues – you can anytime choose to restore the stock ROM by using recovery mode.

Continue the preparation process with a general backup. You see, CM12 can be installed only by using a custom recovery image. Well, that implies in making a hard reset during the update operation. So, you can lose all your personal data, info and accounts. That’s why you shouldn’t complete this tutorial without taking care of the backup process and without temporarily saving everything that’s important for you.

As mentioned already, Android 5.0.1 Lollipop can be flashed on your Sony Xperia Z2 only if a custom recovery image is installed on your phone. CM12 comes in form of a .zip file, so as you know these types of files can be applied only by using CWM, TWRP or similar software. Good; after ensuring the custom recovery image, you also have to root your smartphone. With root access you will remove factory and default restrictions from your device. Ensure this access because the custom ROM will have to change several in built programs, apps and features.

All these are unofficial processes and while completing them the warranty of your Sony Xperia Z2 will get void. Unfortunately you can’t update your phone to Android 5.0.1 Lollipop with CM 12 custom ROM without losing the warranty of your device, this being the only negative aspect that is related to the update operation.

Finally, you have to be sure that a computer can be used; on the same PC you have to temporarily deactivate antivirus protection while on your phone you need to check USB debugging option. Then, you must plug in the charger on your phone if the battery status is showing less than 50% power left. In the end, just remember that this step by step guide / tutorial is compatible only with Sony Xperia Z2 – don’t use these steps for installing CM12 Android 5.0.1 Lollipop OS on a different Android based smartphone or tablet.
