## How to root the Sony Xperia XA Ultra

The Sony Xperia XA Ultra is a midrange smartphone with a bezeless design. It has adequate specs and run Android aptly. These aspects make this phone a great daily driver, however the Sony stock Android is plagued with trashware and all the hurdles Android itself has several privacy problems.

By rooting the phone one can circumvent these limitations. You will be able to improve sound with Viper4Android, block hosts, install dns-crypt and improve overall customability. In the follwing sections I will present the steps to root your phone.

But before proceeding a word of caution (or why you wouldn't like to root your phone):

1. Unlocking your BootLoader will void your warranty, break your device DRM and lose X-Reality and image optimisation on low light when taking pictures.

2. You can save your DRM keys (TA backup) by following this guide: http://xdaforums.com/crossdevice-dev/sony/universal-dirtycow-based-ta-backup-t3514236. You have to do it BEFORE unlocking the bootloader, fro this you need to downgrade to an old Marshmallow firmware, for now you can't root AND restore your backup.

3. You can re-lock your phone and it will restore DRM if you have a backup but you lose root and recovery.

4. Unlocking your bootloader will wipe the device (factory reset)

5. If you have confidential files in your phone don't unlock your bootloader, as long as your phone is locked your data are officially secured.

6. Make a full backup of your personnal data before following this guide.

## Method

1. Find out whether if you bootloader can be unlocked, which is needed to proceed. Type: *#*#7378423#*#* then choose Service info ---> Configuration ---> Check for "Bootloader unlock allowed: Yes".

At this point if the phone has No or any other answer at the screen you shouldn't porceed as rooting will be impossible.

2. Download XA Ultra ADB and Fastboot drivers: https://developer.sonymobile.com/downloads/drivers/

3. Download FLASHTOOL with integrated Xperifirm 0.9.23.2 for Windows, note that you can also use it to unlock your

bootloader(http://www.flashtool.net/downloads_windows.php) DON'T USE AN OLDER VERSION OF FLASHTOOL AND DOWNLOAD FIRMWARES FROM THE

INTEGRATED XPERIFIRM

4. Follow the official Sony instructions for getting the unlock code from [here](https://developer.sonymobile.com/unlockbootloader/). Further paste the code in BLU menu of Flashtool. You can also find video instructions [here](https://www.youtube.com/watch?v=6lKWd5LlUoA).

"boot_delivery.xml" in the "Content" column.

7. Power off the phone again and enter the phone in Fastboot mode (when power off, hold Vol+ and plug the phone). The led should be blue.

without .img at the end.

## Conclusion
