Hello!
I bought a phone, with unlocked bootloader and root. Z3 D6603
I dont know exactly how the previous owner unlocked BL etc.
But I flashed it to 23.1.A.1.28 lolli, fixed super SU and dualrecovery.
The thing is, I now want to return it to stock, so that i can get OTA updates by Sony Companion, and i have no idea how to do so.
Searched the forums, and found a lot of info, but I dont want to brick or ruin anything.
Do I need to flash stock firmware without root, remove dualrecovery or relock BL, or maybe all of it?
I posted this earlier, and im not sure if I explained it right, I said I wanted a step by step guide.
What I meant was a guideline in what ORDER to do stuff, not how to do them.
Is it enough to relock the bootloader, and then use Sony Companion to update, or do I need to flash something, maybe go back to original recovery first?
Help is sincerely appreciated !
PS: Sorry for posting again, but I dont know how to change the headline/bump the post, and need this done ASAP, or else I wont have a working phone in a few days. ( Change of sim card)

Please? Anyone?

Nothing. If it is unlocked and you dont have backup of original TA partition. There is no help. You can't get you DRM keys back and without them you cant relock to original state. And majority of Sony stock fw simply doesnt provide OTA for unlocked bootloaders, except for the new Sony Concept ROM.
You may try to download Androxyde Flashtool as it provides relock function, however it doesnt restore TA. If it brings OTA back not sure, because I always backup my TA so just try it.

Hi,
I have been using Xperia z5 for long time have unlocked bootloader (lost DRMs) rooted and installed custom roms.
Now, i want to give this phone to my cousin who loves stock rom only and prefer to get OTA only. I want your help in stimulating the drm (using the famous patch), install stock latest, relock and Unroot.
Please advise me about the steps that i need to follow as i am feeling bit confused.
Thank in advance
You can't simulate the missing drm keys with locked bootloader. Sorry.

Welcome Felix! Sony devices are easy to flash and bricking it is almost impossible with Locked Bootloaders (LB).
All you need is FlashTool by Androxyde, the latest version of it allows you to download the latest firmware for your specific phone model.
Currently full root under LB is currently under development and is only available for Unlocked Bootloaders (UB) only.
Please refer to this link as this is the most important thing you perform when planning to root your device the other way.
-Sony keeps check of DRM keys stored on TA partition to enable some of its proprietary apps functional, without it they just stop working normally.
Backing up TA partition:
http://forum.xda-developers.com/crossdevice-dev/sony/iovyroot-temp-root-tool-t3349597
also that means that it is not possible to flash other roms until full root is confirmed ?
Wich advantages do i have with this temp root ?
Hello,
Since i am new to rooting on a Sony device , i tried it downgrade to lollipop in order to backup the keys all is fine.
I am now back to stock, since i cannot understand some things.
I want only a stock root rom, but i want to keep the drm in place or simulate it in some way i dont wanna lose some funcionality of the phone is that possible?
Since i read things about drm fix etc.
Can someone explain what is possible with Sony and rooting with emulate or replace drm after root.
btw sorry for my bad english.
Just flash patched stock kernel with drm fix and you are good to go. btw check for it in Xperia Z5 Premium forum, not here.
Hello,
I resort to the kindness and experience of the forum to be able to advise me on the basic questions about the experience of rooting the Sony XZ Premium (G8142), since I spent several hours reading and searching the forum for information, but everything that is there is scattered, then I would like to know from those who directly did it, if it is worth it. Also, in order to help other users who are looking for concise information, they can have this link as a reference to remove all the most common doubts that arise in one place.
My doubts are the following:
is it advisable to root?
I have been researching about the camera problems that for Android 9 no longer have them, but in another article it describes that we lose the video enhancement X-Reality, DSEE HX, ClearAudio +, Widevine L1. All this arises because a certain system partition (TA) is erased when we unlock the bootloader. Does anyone have info how he remedied all these leaks? Custom ROMs fix this?
DRM issues: This is also something that was not clear to me. First do Backup DRM; In order to be able to backup to the partition with the locked bootloader I still need to run the temporary root. For that I need to downgrade the system to version 8 (G8142_47.1.A.16.20). Then run command lines to create the backup with the help of the tool that a forum user created. Please if I'm wrong correct me.
* The question is first to downgrade (Android 8),
* temporary root,
* then create the backup.
* Unlock bootloader from sony page
* then to restore the backup again, or not? Does restoring the backup lock and leave the device to a previous state? (undoing the changes), or does it just fix the DRM problem?
* In short, is it advisable to unlock the bootloader with Android 9 or earlier?
* Is it advisable to create the DRM backup?
* In which case would I have to restore this backup?
I have also seen that they mention a paid software that does all the work by yourself I do not know if it is for Android 9, it is just a matter of connecting the device in fastboot mode, then it automatically executes twrp, root, repairs DRM, but the cost of the software in my country it is something difficult to pay, that is why I am gathering as much information as possible before executing any procedure.
Custom ROMs: Regarding the user experience, does anyone have information about the rom that is more stable and recommended for this device? Does it cover all the holes or bugs that it leaves when erasing DRM after unlocking the bootloader?
I hope the reference text of what I write can be understood since my native language is Latin American Spanish, and I am using the Google translator.
I would appreciate any kind of suggestion or experience in this regard. Thank you.
First of all, have you seen these threads:

It's all there really, explained step by step. Thanks to @j4nn you can run stock firmware with superuser access concealed from the system so that it doesn't know the phone is unlocked, with all the DRM-restricted functionality still available.
The relative benefits of unlocking depend on your specific needs. But considering there are no more official updates, being able to use aftermarket firmware like this: https://forum.xda-developers.com/t/rom-lineageos-18-1-unofficial-updated-2021-3-31.4221427/ already makes it worthwhile in my opinion.
The only drawback of an unlock is that there is a scary message displayed on every boot, which also adds 1 or 2 seconds to the startup sequence.
Regardless of whether you decide to unlock or not, there is no downside to having a TA backup. It might come useful one day.
All you need is Android Platform Tools (adb, fastboot), and: https://forum.xda-developers.com/t/tool-newflasher-xperia-command-line-flasher.3619426/ There is no need to pay for any of these, although you can donate to @j4nn and @munjeni: they both put a lot of effort into making this possible.

Thank you very much for answering my question, you have clarified several points that I had scattered about.
I still have some doubts reading more comments on the links that you have suggested. Perhaps you have an answer to such doubts:
I have read that a user has lost video enhancements, perhaps because he did something wrong here:
temp root for drm keys backup - anybody still interested?
--- edit 2018-11-03 --- Tools to backup TA partition before bootloader unlock have been released. Just check the [XZ1c/XZ1/XZp] temp root exploit to backup drm keys implemented thread. --- Just wondering if there is already drm keys backup...
forum.xda-developers.com
post #72 sulistyoarif:
Only Video Image Enhancement didnt work for me.
I have seen some videos of the YouTube profile of the user j4nn where he has all the libraries without problems, working perfectly, including the improvements of the video image.
About the installation processes for firmware I did a clean installation of firmware version 9 latest compilation with Xperia flashtool without problems. Do you think that I will be able to downgrade with Xperia flashtool without problems with the libraries or some other? I think that the experience serves me more than the tutorials .
For what remains in my information I found this steps:
*downgrade
* no flash - persist.sin
1) Use temp root and backup TA image
2) Unlock bootloader
3) Flash Newest firmware (or choice of yours)
4) Setup phone temporary and copy magisk files to
phone
5) flash twrp and temporary boot with twrp
(fastboot boot twrp.img)
6) flash magisk and reboot
7) Check Root privilege
8) Restore TA image and check DRM
8.1) (optional) factory reset if any fc issue
"Now You have unlocked and rooted phone with full DRM Support including OTA Support.
Everything is tested and working for XZP and XZP Dual"
Thanks again for the help and taking the time to read my post.
@sergioemmr
It should work like you describe it, except with newflasher: https://forum.xda-developers.com/t/tool-newflasher-xperia-command-line-flasher.3619426/ FlashTool is for older devices.
That guy did something wrong, so don't be like him. Just follow @j4nn's instructions.
You can downgrade to an earlier firmware on this device, no problem here. Do not flash persist.sin like you said, and you're good to go. If you run into any problems, just post in that thread, and you'll get more people's attention.

What's the deal with persist.sin? I used flash tool to downgrade and managed to extract the unlocked-ta file. Did I somehow void the TA key?
