I'm happy to share with you an updated guide on how to root the Xperia XA and Ultra, big thanks to @luis1981 for the update.
This guide is Only for Marshmallow (Android 6.0), for Nougat (Android 7.0) it's here: https://forum.xda-developers.com/xpe...-noob-t3638727
## How to root the Sony Xperia XA
The Sony Xperia XA 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 install the Xposed framework, 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, I found a workaround here: http://forum.xda-developers.com/cros...s-drm-t2930672, use zip for Z3+ devices.
2. You can save your DRM keys (TA backup) by following this guide: http://forum.xda-developers.com/cros...ackup-t3514236. You have to do it BEFORE unlocking the bootloader, for now you can't restore your backup.
3. You can re-lock your phone but it will not restore DRM
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.
1. Find out whether if you bootloader is 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 ADB and Fastboot drivers: https://developer.sonymobile.com/downloads/drivers/
3. Download FLASHTOOL with integrated Xperifirm 0.9.22.3 for Windows, note that you can also use it to unlock your bootloader(http://www.flashtool.net/downloads_windows.php)
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).
5. Root Your Stock Rom with TWRP and in order to do that you will need the proper files for your phone version:
SuperSu zip package for all XA: http://www.supersu.com/download
For XA single sim = F3111, F3113, F3115
TWRP recovery: https://forum.xda-developers.com/xpe...ry-xa-t3606488
For XA dual sim = F3112,F3116
TWRP recovery: https://forum.xda-developers.com/xpe...l-sim-t3606232
6. Copy SuperSu zip package on your MicroSD.
7. Enter the phone in Fastboot mode (when power off, hold Vol+ and plug the phone). The led should be blue.
8. Flash recovery and boot with "fastboot flash boot boot.img" and "fastboot flash recovery recovery.img" commands (rename downloaded boot/recovery image if needed). The simplest way is to use fastboot from Flashtool in x10flasher folder, copy recovery and boot in it, open command prompt, flash them and then delete them.
9. Unplug the phone, hold "Vol-" and "Power" buttons. Release all buttons after phone vibrate.
10. You are in TWRP recovery, on password prompt press "Cancel"
11. On next screen press "Swipe to allow".
12. Go to "Install", "Select Storage", click "Micro SDCard". Optionally, you can format "userdata" partition now and remove internal encrytion for restoring TWRP backups/acces of /data partition, go to "wipe" and tap "format data".
13. Go to your SuperSu zip directory and click on it to install. Optionally, If you want to flash Xposed, DRM fix or any flashable zip, repeat the previous step for each zip. You can mount your SD to PC in TWRP for easy access.
14. Reboot the phone, during init the phone will reboot one more time.
15. Your phone is rooted
You can optionally switch from SuperSu to Magisk by following this guide:
After these steps your phone should be rooted and you will be able to have root access to the system. This tutorial comes with no garanties that it will work and the author does not take any responsibility for you bricking your device. Also, installing third party files are a security liability, you should be aware of that. Despite these issues, rooting the Xperia XA has been confirmed to work in all models.
Note that this the guide is the same for XA Ultra, the only differences are the boot/recovery files. You can find files for XA Ultra in their respective forums.
## Old guide with video
As requested I make a "how to" video to be more noob friendly, the video is probably not perfect and my English too but I do my best to be understandable to all
I'm not a dev and I have no responsability if you flash my files.
As said in the video you must wipe "userdata" partition when flashing IF your phone memory IS crypted or if you don't know the uncrypt password, someone on the web speak of "default password" but what is it ?? If cryped (with no password) you can't backup /data and can't mount internal memory in TWRP. You can manually enable encryption and be able to set YOUR OWN password, but you can't revert back. And in theory you can make full nandroid backup and mount /data partition when in TWRP but can't mount inernal memory.
Regarding mounting /system rw in TWRP, seen on other tuto, you must never "swipe to allow modification" when prompted, after installing root package /system is mounted rw with no problem (look at "mount" menu). EDIT: tested on my device without issues but be careful.
IF YOU UPDATE OR FLASH STOCK BOOT and power on the device to Android, it will encrypt again the internal memory and if you shutdown the device before the end (xperia screen for hours) it will corrupt your data, not the SD card).
For futur, if you want to update, ask me and will release modified boot. I don't know what it does if you update stock after setting password encryption :/
Why I changed that by replacing "FORCENCRYPT" by "ENCRYPTABLE" in fstab Boot:
Before continue, you must understand that unlocking your BootLoader will void your warranty, break your device DRM and lose X-Reality and image optimisation on low light when taking pictures (seen some workaround but not for XA).
You can't re-lock your phone and it will not restore DRM.
If you have confidentials files in your phone don't unlock your bootloader, as long as your phone is locked your data are officially secured.
This will be repeated when following Sony step by step guide. YOU ARE AWARE !
To verify bootloader lock state after unlock, on phone dialer:
*#*#7378423#*#* ---> Service info ---> Configuration ---> Check for "Bootloader unlocked: Yes" IT MUST BE YES !!!
By rooting your phone you will be able to install/uninstall system apps, install Xposed framework (Gravity Box, Dark Pokemon Go,...) or Viper4Android for an awesome sound! You can tweak and mod your phone deeper (battery,CPU,...), build and flash custom ROMs and many other things
If you have problems or want to unroot you can flash stock firmware like in the video with Flashtool, no need to wipe userdata.
Please watch my video one time before begin, to understand what you have to do.
Free to you to distribute or modify my files but please link this thread as source.
BY FOLLOWING THIS GUIDE YOUR PHONE WILL PERFORM A FACTORY RESET WHEN UNLOCKING BL ( it will not format SD card) , MAKE BACKUPS !
Edit 3/08/2016: Found a workaround for Sony DRM function restoration for UB devices based on Z line and working on XA Please read the thread, download package zip for Xperia Z3+ and install it with TWRP, that's all! I recommend you to install it just after SuperSU zip package (working too if not doing this). Thanks to @jimRnor
EDIT 13/08/2016: TWRP is 99% working (can't wipe /cache), you can do all as you want, as long as no encrypted partition is present or locked.
My first video guide : http://www.youtube.com/watch?v=nnOoLo31ka0
MP4 offline video download: https://mega.nz/#!RlwVSAKC!6lTBZxVnL...UWIq8lEUfSp4Zw
Download XA ADB drivers, all models for Windows
Download XA Fastboot drivers, all models for Windows (if needed, installation is same as ADB drivers in video)
Download FLASHTOOL with integrated Xperifirm 0.9.22.3 for Windows
(if needed you can unlock bootloader with it, I unlocked my device with it)
Just follow official way and when you get the unlock code, paste it in BLU menu of Flashtool. (faster way)
The step by step guide to unlock BootLoader by official way:
Video (not mine): https://www.youtube.com/watch?v=6lKWd5LlUoA
(Just select Xperia XA when asked)
Now depending the firmware you want to root ( the one you downloaded with Xperifirm) choose your rootpack:
For XA single sim (33.2.A.x.xx) = F3111, F3113, F3115
For XA dual sim (33.2.B.x.xx) = F3112,F3116
I see some users who ask without searching (a very little) before, PM messages inclued, some others who spam threads not related to their problem or create new thread for nothing and who do not know what politeness is at all . Until now I was nice and answered them but now I will change that, NO MORE HELP FOR THAT KIND OF USER !!!
Now if you have no answer from me you will know why.
