Actually it seems that Japanese xperia models can be flashed with international firmware, making them exploitable for drm keys backup.

I've updated the TA backup guide with following:

Sony Xperia XZ1 (SOV36) /added on 2019-08-22/

this Japan version can be flashed with fw for G8431 making it exploitable as standard XZ1 (the possibility to use G8431 fw is confirmed here and also here)

/this confirms there might be a possibility of TA backup for few yoshino platform phone models that are possible to flash with one of the above firmwares (and boot ok even though designed for other phone variant)/

And previously also with this:

Sony Xperia XZ Premium (G8188) /added on 2019-04-24/

this Japan version can be flashed with fw for G8141 making it exploitable as standard XZp (tested by zatsune as documented here)

/this confirms there might be a possibility of TA backup for few yoshino platform phone models that are possible to flash with one of the above firmwares (and boot ok even though designed for other phone variant)/

[MENTION=6808978]tujiacai[/MENTION], maybe yours Xperia XZ1 (SO-01K) could also be flashed with firmware for G8431 in order to use renoroot temproot for TA backup?

Hi [MENTION=4418980]j4nn[/MENTION], please forgive me for my late reply.

My status is out of the bounty since by the time the solution was given i did not longer had the phone, hence is wasn't useful for me anymore by that time. I wish i have the phone yet but i had so many problems with it that i've ended up wrapping it up and sending it back to the seller with a rock attached since they refused to validate my warranty. I'm really glad you came out with the solution and that many fellas out there are taking benefits of it.
[Sony Xperia XZ1  Guides, News, & Discussion] Az Biker:
* * * Thread Cleaned * * *

A few unnecessary comments have been removed or deleted.

Bounty thread or not, valid frustrations or not, Forum Rules must be observed nonetheless.

There are SEVERAL mitigating circumstances within this bounty thread, those who have not paid, and notifying those who have pledged a bounty.

1) This bounty thread was started exactly TWO years ago. Problem with that is MANY users no longer have this device, some are no longer members of Xda, and some have resolved to dealing without root.

2) While I believe a promise made should be kept, I do not agree with shaming, insulting, or listing names in basically what could easily be seen as a personal attack, which violates forum rules.

There are better ways to accomplish this; use the PM function, or list the names of all who made a bounty pledge, as a reminder to those who have not yet fulfilled their obligation (without labeling them, or giving the list a disrespectful title). Whether or not "deadbeat" users deserve the scorn and embarrassment, listing their names in a derogatory way can been viewed as a personal attack. This has no place within Xda.

3) As far as desiring a change, discontinuance, or modification of bounty threads; contacting Dev Relations, anyone on the Moderation staff, or even Xda Admin are much better courses of action than allowing frustrations to overflow into the thread.

I fully understand the frustration of the hopeful user wanting their device unlocked or rooted, as well as the person who dedicates tons of their time to meet the conditions of the bounty, to only have a portion of those promising to pay actually pay.

No one is saying the frustration isn't valid or deserved, it really just has no place in the Xda thread.

I will bring these concerns to fellow Moderation staff attention for discussion.

Meanwhile, thanks for everyone's understanding and cooperation in remaining respectful when posting in Xda.

tl;dr

-Please remember that ALL posts/comment must be respectful and non-insulting

-There are better places to voice concerns with Xda policy than within Xda threads

- Mitigating circumstances can create less than desirable circumstances
[Sony Xperia XZ1  Guides, News, & Discussion] j4nn:
Ok, I am sorry for that not very nice post.

Just to be accurate - my solution was posted here about ONE year after the thread start (so two years thread age is not that relevant).

Several trials to contact have been made, the last one via PMs about 5 months ago.

Ignoring the PM while being active on xda is not very nice either in my opinion.
[Sony Xperia XZ1  Guides, News, & Discussion] snake218:
You are very wrong, and wrong attitude. in my case i told you and explain i already unlocked my bootloader and lost my drm keys long before you post your solution, so it didn't has/had no utility for me. You can't force people, just because you want to.
[Sony Xperia XZ1  Guides, News, & Discussion] j4nn:
[MENTION=4929083]snake218[/MENTION], obviously I cannot force anybody to do anything.

It's all about at least responding instead of just ignoring any way of contact.

The deleted post mentioned you only in the context of

"Two users (<users removed>) have been honest and at least responded in PM politely refusing to honour their pledge."

- that seems to be in accordance with your stand on your pledge, so actually I like that you at least responded to the PM in (a nice) two weeks time.

So I am not sure what I am very wrong with exactly?

Who are you talking to? That's what the "REPLY" button is for. So everyone understands who you're responding to.

Also, if you're responding to sToRm, then you're not that bright.

He already has a DRM patch working for the XZP and is looking to port it to the XZ1 / XZ1c, so he needs someone to test it.

Obviously, if he was working on the XZP, it's because he owns an XZP rather than an XZ1.

Would you prefer he not try porting his fix to the XZ1?

OK updated bounty.

Based on your PM and this message however, I don't think you understand how a bounty thread works. You keep asking me like I'm developing a method, I'm not. The bounty thread is to reward -whoever- comes up with a root method, the OP (me in this case) is 99% of the time -NOT- the one trying to develop a solution to get paid.

You don't go around asking the person who helped put "Wanted" posters around town about why they haven't caught the criminal yet - because that's not their job, they're just a messenger.

If I gave you a solution for root and DRM restore (without backup of the keys), would that match the requirements of this bounty? I have already rooted the XZ Premium on Android Oreo and realized a DRM patch for it, as I did before under Nougat. Camera, Audio,... are working smooth. The relevant files are almost identical to XZ1, so it should be possible for the XZ1 as well. If it matches the bounty, I would focus on it and make the files available after testing. You decide.
[Sony Xperia XZ1  Guides, News, & Discussion] marcelcerdan13:
For me it's a solution that meets my needs. So I will pay what I proposed to get it. I'm in.

Will you do some follow up on next Android release like updates or will we be stuck with current version ?
[Sony Xperia XZ1  Guides, News, & Discussion] sToRm//:
Sure. I have a XZP and if there are updates in the future, I will patch it again if there will be differences in related files. I think XZ1 will get the same updates, so it's not that problem to release patches for it, too.
[Sony Xperia XZ1  Guides, News, & Discussion] Belyavin:
Can you please clarify one thing? With each new software update do you only need to reapply the patch, or you should modify the patch itself? Is this modification something that requires specific skills?

Nevertheless, great work! I'm ready to donate as soon as it's comfirmed on xz1c.
[Sony Xperia XZ1  Guides, News, & Discussion] Grutinet:
Great work ! But I need a precision about what you said. What is the difference between DRM restore and backup of the keys ? I thought it was the same thing.
[Sony Xperia XZ1  Guides, News, & Discussion] marcelcerdan13:
DRM restore would request you to be able to backup your DRM keys, then push them back on the OS after unlocking the boot loader and rooting the device.

Here the solution will be to make the OS believe the DRM are still there even if actually they're not and wiped out forever when you unlock the boot loader. This is the general idea as an newbie like me can comprehend it , you'll get more details on that post for instance : https://xdaforums.com/xz-premium/development/hack-mod-sony-xperia-xz-premium-twrp-t3695171

Sony deserves to get the middle finger for that stupide policy they're implementing they give an opportunity to unlock the bootloader, root, push custom ROM from one hand but take back essential features like camera from a $600 or more device while pretending to encourage the dev community to use their devices. Thank you so much ... All that for this stupid DRM vison of the past. Thanks a lot sToRm// for sending this back in their face !
[Sony Xperia XZ1  Guides, News, & Discussion] sToRm//:
My patch is a restoration of the functionality, like the phone is locked. The unique device key is lost if you unlock the device, but with my patch it works like a charme as if the key would be there.

[Sony Xperia XZ1  Guides, News, & Discussion] 4rz0:
If you ask me, the highlighted paragraph is indeed satisfied by the way XperiFIX works.

So yes, the bounty would go to this guy.
[Sony Xperia XZ1  Guides, News, & Discussion] roytam1:
But the method that [MENTION=8363210]sToRm//[/MENTION] provides kills TA and no way to restore TA partition.
[Sony Xperia XZ1  Guides, News, & Discussion] pbarrette:
That's true.

However, the highlighted C clause only calls for a restoration of the functionality, regardless of whether the TA partition and its DRM keys can be backed up and/or restored, which is precisely what sToRm's fix does.

It is a little confusing because in the rest of the Android world,

rooting

means gaining the privileges associated with linux userid zero. But because Sony can't be bothered to use proper terminology, in this context it can mean either unlocking the bootloader or gaining userid zero level elevated privileges.

Clause A of the bounty seems to refer to

root

as an Elevation of Privilege exploit only. Clause B seems to refer to a situation where

root

could mean either an EoP, or bootloader unlock which would allow the DRM keys to be backed up and restored. While clause C is referring to restoration of fuctionality after unlocking the bootloader without regard to the contents of the TA partition or the original DRM keys.

Personally, I'm still holding out hope for an Elevation of Privilege exploit before I unlock the bootloader on my XZ1c. That said, if none appear, then sToRm's fix will satisfy my needs once my phone is out of warranty.

When he first released the fix, I examined the changes sToRm made to the

secd

binary and did a comparison against the

secd

binary used in the XZ1c and found that they were quite similar and likely also able to be patched, and it seems that he has done just that. Though due to the lack of a stable, working TWRP, there are few (if any) testers.

Based on my assesment of his patch and my desire for an EoP exploit prior to bootloader unlock, I already donated my bounty pledge to sToRm, but will keep my bounty active in case someone discovers a way to gain Elevation of Privilege.
[Sony Xperia XZ1  Guides, News, & Discussion] karlchen68:
in my opinion but that is never the sense and ruins everything. also the warranty expires in many countries, the delivery condition can no longer be established and for this reason, the device can no longer be sold as "original".and who guarantees that the fix will work after an update? in reality nobody !!! Sorry for my hard words, but a loss of original ta partition is never never the sense and the target of this thread.The people do not want any fix that may not work in half a year(then maybe come the next bounty thread??), they are waiting for a right solution.The Sense of this Bounty Thread is a Backup of Original TA so i can every time restored that

similar to Z3/Z5

etc. device line after that restore the device is in original sony condition again A "fix" for what ever is only a (bad or second) solution for people, tey can't wait for the right solution as the past has shown by other Sony devices.

And remember, a loss of the original device keys can never, never be undone,absolutely no matter what comes in the future!!
