Requirements

If you haven't unlocked bootloader yet check this guide
Good News ! For advanced users If you have TA.img backup of your device I highly suggest using this tool to patch stock kernel using your own TA image to have drm working with latest Magisk 16.3. Follow TA_POC METHOD instructions below .

- Kernel (boot.img) + Magisk + DRM fix patch : Here
- Latest TWRP from here[/B]
And obviously :
- ADB and FASTBOOT : https://forum.xda-developers.com/showthread.php?t=2317790
- Xperia X PERFORMANCE drivers : https://developer.sonymobile.com/downloads/drivers/xperia-x-performance-driver/
- FlashTool : http://www.flashtool.net/downloads.php

What are DRM Keys ?

If you unlocked the bootloader on a Sony Xperia device, you probably know that the potential loss of warranty is not the only disadvantage you have to accept. Another fairly hidden issue is related to various proprietary features such as the X-Reality color mangement, BIONZ image processor and the active noise cancelling techniques. Once you decide to unlock your bootloader, the process also removes a piece of data referred to as the DRM keys. These are tied to various services (such as streaming video and the like) offered by Sony but are also required for the features mentioned above to work properly. Put simply, once the keys are gone, you’ll face issues such as decreased low light camera image quality and the lack of the X-Reality mode.

Kernel features

this is pure stock kernel of the mentioned above firmware with
- RIC disabled
- added DRM patch support

Instructions
Before proceed backup all you important data like pictures, files to another device.. !
Make sure you follow all steps carefully with caution .. !

01- Flash Oreo FTF via Flashtool (Full wipe is recommened exclude nothing except TA files if there's any)
02- When done flashing unplug device ..
03- Enter fastboot mode and flash TWRP (hold vol up + plug usb)

fastboot flash recovery twrp-3.2.1-0-dora.img

then flash kernel

fastboot flash boot boot.img

04- Unplug and enter TWRP (Hold vol down + power button)
05- In TWRP Flash drmfix.zip + SafetyNet Cleaning Tools.zip then Magisk v16.3.zip
06- OPTIONAL Flash ROM Ptach to clean system and remove all bloat apps
07- Reboot and enjoy

TWRP asking for decryption code / Internal Storage showing 32GB only for DUAL Model

Turn off the phone (from TWRP if you can or hold vol up and power button till the phone vibrates 3 times)
Enter Fastboot and format user data partitions using this code

fastboot format userdata

If you are getting error try from TWRP recovery > WIPE > Swipe to format data
Now start your phone and set it up the issue should be resolved.
If still storage is not showing do clean installation in Flashtool wiping everything and exclude nothing then follow then instructions above .. I also noticed that flashing the correct XZ DUAL boot.img the first time before first boot fix this

[serajr]

Finally, got it!

Great!! Did you do anything other than the OP instructions?

 

[GAndrel]

Hi,
I also managed to apply the procedure.

Links in requirement are not pointing to newsest TWRP and Magisk. They are pointign to TWRP 3.0.0 and Magisk 14.3. Now available are TWRP 3.1.1 and Magisk 14.5.

Generallt method one worked with full total wipe while flashing Oreo with flashtool.

 

[ramirrat]

Great!! Did you do anything other than the OP instructions?

Used method 2, but flashed this TWRP

 

[gshumway]

YES ... the Problem was TWRP and MAGIKS. Thank You. I used Method 1 - ok
but "SHAME ON SONY" - still no RAW Format for Camera with Oreo. I will go back to Oreo AOSP - so i can use Google Camera with RAW.

thnx
gordon

 

[Mastiff]

Is it possible to root with SuperSU instead of Magisk? I had a lot of camera problems when I used Magisk. It's up to 2.82 now, I think that' a general Oreo compatible thing.

HI, i'm just doing this guide. i've download the firmware from xperifirm, and i got 3 files withount extension. I've googled and i read a guide to converto these 3 files into a ftf via flashtool. At certain point, i have to select all files except all the .ta files, and create the zip. I'm right?
The files are:
auto-boot.ta
cust-reset-ta
fota-reset.ta
master-reset.ta
osv-restriction.ta
reset-kernel-cmd-debug.ta
reset-non-secure-adb.ta
reset-wipe-reason.ta
simlock.ta

 

[gyk0502]

thanks... method 1 [email protected] AndroPlus TWRP 3.1.1.0 used.

 

[Mastiff]

Up and running with method 1. Unfortunately I had to use Magisk, but so far it seems to behave. SuperSu does NOT work. It will install, but the device does not show root.

 

[25agosto]

Installed and running with method 1 but got a lot of issue using Windows 10. So i do all the work on a Windows 7 laptop without any problem.
Just 1 thing not working: magisk.
I followed the guide step by step with success, but magisk says me to update, and when i hit yes, nothing happen.
See attachment.
And another thing. I've wiped all except fotakernel, so why when I've boot up the Phone, i find all my apps, my settings and wallpaper Like how i leave them?
Sorry for my English.....

Edit: can't use netflix anymore
Edit2: magisk problem solved. I've download The apk from The site, then installed and when i hit yes to install magisk, it download a flashable via twrp zip, flashed it and magisk work, but now I've Lost safetynet for no reason.....
But i can use netflix now.
Safetynet is a important thing?

 

[Mastiff]

I forgot to say that I used Windows 10, as always. Regular command prompt (writing cmd in the start menu will give that, nothing else). But problems with that is usually because of wrong drivers for the phone, nothing else.

 

[25agosto]

After 2 days of usage, i noticed a lot of lag, so i've done a factory reset from the android menu, not twrp, and is all working fine withount any kind of lag (except at powe off, the circle stop running, then after 20 seconds, power off, but it's not important, maybe a sony bug).
Now can i reflash from twrp in order drmfix.zip, SafetyNet Cleaning Tools.zip then Magisk v14.5.zip, or i will do any mistake?
I've noticed sone remote play, netflix, sony news and sony lounge are not working, i think cause DRM
