 Sony’s new Flagship smartphone, the Xperia XZ with SD820 & 3GB of RAM is a sweet deal with Sony’s premium built quality.  Now as usual, rooting your smartphone can give you additional functionality and control over your device. If you don’t know what Rooting is then, here is a link to more information. Once, you have decided to root, you need to check some prerequisites.
DISCLAIMER: Your warranty will be void. Please proceed at your own risk.
Prerequisites
  1. Minimal ADB: Setup ADB and Fastboot
  2. Sony Xperia XZ USB Drivers: Download
  3. Charge your device upto 50% to avoid any shutdown during the process. We won’t be responsible if your device gets bricked during to no charge.
  4. Backup all your data, Apps, contacts & everything your need. Although this process won’t erase any data (except unlocking bootloader), we need to create a restore point in order to restore if anything goes wrong.

How to Root Sony Xperia XZ

  1. Unlock Bootloader: Opens the door to System files of your device. This allows you to flash images onto the main system partitions of the phone.
  2. Install a Custom Recovery: A custom recovery is flashed onto the recovery partition of the device and overwrites the stock recovery that exists by default. Custom recoveries bring lots of functionality and allows you to perform wipes, install flashable zips, create full backups of your NAND (Nandroid backup), and various other features. An unlocked bootloader is needed to install a custom recovery.
  3. Install SuperSU zip: You can gain root by flashing SuperSU through a custom recovery. A custom recovery allows flashing the SuperSU files into the system files. You can unroot your Android device in just one click.
Unlocking bootloader can cause some deterioration in low light camera performance and loss of DRM keys. It will also factory reset your device and format your data. BACKUP your device first!

The first step to rooting your device or flashing ROM is to unlock the bootloader. To prepare your device to be unlocked follow the following steps:

  1. Great, thanks for sharing this post all about the Sony brand phone. I came here for the unlock code method. I saw your blog post and all the post are amazing. Talked about this post, I was also struck in the phone unlocking problem during changing the network carrier of the SIM. My phone got locked and I didn't have any option for unlocking my phone instantly. Then my friend suggests me to use unlock codes for instantly unlocking the phone. Simple I shared my phone information such as IMEI number of the phone with country and operator by dialing *#06# into the phone. Follow these steps, I easily unlocked my phone within a few seconds.
