GUIDE UPDATED, TESTED AND SIMPLIFIED 15.2.2017 (thanks to munjeni)

Tested with Saudi Arabia, Germany and Nordic (.378) firmwares

I managed to get my Xperia Z4 Tablet (SGP771) LTE model to have root, TWRP-recovery*, munjenis DRM fix and Adaway working with Nougat firmware (Saudi Arabia). I will share steps that I have done with my own tablet. If this guide brick your device or something goes wrong, I am not responsible for loss of your device. Use this guide only with your own RISK!

This tutorial is not for beginners. You need to have working adb installed yout pc, unlocked tablet, sonys special driver for fastboot. and TA backup (example TA-21062016.img). Use only this tutorial with Sony USB-cable.

*To get TWRP working, you need: OTG-cable and a mouse with wire or wireless mouse with a dongle.

0. Download Nougat 32.3.A.0.376 (Saudi Arabia) firmware with Xperiafirm 32.3.A.0376. to your PC

1. Flash Nougat 32.3.A.0.376 (Saudi Arabia) with Flashtool 0.9.23.2.

2. Boot your device and enable Developer settings from setting

3. Enable USB debugging setting from Developer settings

4. Download Supersu and Magisk to your device:

5. Shutdown your device

6. Download munjenis DRM fix and serajr script package v2 to your pc:

7. Decompress files from munjeni and serajir to same folder.

8. Extract kernel.sin from your nougat firmware ftf (You can use 7zip to do this). Copy it to same folder with DRM fix. Rename kernel.sin to kernelX.sin

9. Copy your TA backup to same folder with DRM fix and rename it TA.img

10. Open Cmd with admistrator persimmions and use DOUBLECLICKME_NOUGAT.bat (search cmd rght mouseclick use admistrator).

11. Follow munjenis tool tutorial: You can choose if you want Sony Ric off. I left it on but turned dm verity off.

12. Download TWRP: https://drive.google.com/drive/folders/0B0j3VJ1Xp5N8cnhQamtxRWVtRmc

13. Press vol up and connect your device to pc to use fastboot. Use command: fastboot flash boot new_boot.img

14. After that use command: fastboot flash recovery TWRP-3.0.2-0-20160604.img

15. Disconnect your device and put otg-cable to tablets usb and connect mouse to otg-cable.

16. Press vol down + power to boot to TWRP. Touchscreen is not workin but you can use your mouse to navigate in TWRP!

17. Allow TWRP to make changes to your device and flash Supersu 2.79 and Magisk 11.1.

18 Boot your device and install magisk manager from the play store.

19. Enable from magisk manager settings: busybox, magisk hide and systemless hosts and Install Adaway (Will not work without Magisk, strange).

I have not managed to get my CTS profile approved but that is not major issue if not playing with Pokemon go (You can use magisk to detect this).

Note1 : Change LTE to 1 priority from mobile setting. Default for SA firmware is GSM :)

Note2: If you have already tried rootkernel to get drm working; do a full wipe and reflash firmware with flashtool. Rootkernel messes something. Tablet do not boot if you have used rootkernel and after that try to use munjenis DRM fix.

Note3: Magisk 11.1 wont work with Xperia Z4 Tablet without Supersu. So flash Supersu first and Magisk 11.1 after that

Note4: You cannot boot to TWRP by using root and reboot to recovery apps. You need to boot to the recovery with keycommand voldown+power

I hope this guide helps some fellow flashers :D
