Question Is there a way to restore missing DRM functions like was done in a MOD for Z series? - Sony Xperia 1 IV

see this: https://www.naldotech.com/restore-drm-keys-unlocking-bootloader-xperia-devices-lost-drm-keys/
This does not exactly restore the DRM keys, but does restore lost functionality which is the main reason people would like the DRM keys back.
Is it possible to do the same mod for the Xperia 1 III/IV?

The features that mod restores are no longer lost when unlocking the boot loader on modern Xperia phones. You only lose 4K/HDR Netflix capability as you lose widevine L1 keys.

When you relock the bootloader and use repair with xperia companion, the drm keys get restored but only with xperia 1/5 i,ii,iii and probarly also with iv series.

There is no need for DRM messing on these phones. I have unlocked bootloader to de-google my device and activate call recording, haven't seen any quality issues. I don't care about Netflix , social media "brain sheep washing" or gaming. My device works fine. Really having enough of going to a party and 90% of my friends cannot put the phone down for 2 minutes and have a conversation.

de-google. Sorry, For my own security i cannot have any google framework running in the background. So i am removing all google related apps. Using free OSS alternatives, the Google dialler that installing also modified, and it does not have access to many of my phone details and internet.

[Q] What to use for backups

I read on Google Play that Sony had disabled Helium. Anyone know why?
I am looking for a backup and restore app that covers everything without the need to root the XZT. There is a built-in app that seems to have covered it but does it? I have just had to re-build my device and used the restore from the PC companion and it was awful. I've spent another day re-downloading and configuring settings and apps.
Is there an app that backs up and restores everything including the folders and icons on the home pages?
Thanks

Is there a reason why you don't want to root it? Afaik you wont void your warranty unless you unlock your bootloader.
Titanium backup never failed me.

Yep, When I rooted before, I lost SkyGo and this is important to me. As much as I would love to be rooted, this is one facility I don't want to sacrifice.

[Q] Facebook Messenger Crashing

Hi there, proud new owner here, a tiny bit dissapointed with washed out colours /Im coming from an unbeatable amoled screen of Samsung Galaxy Tab 7.7/ and not being able to sync my Jawbone Up /did anyone manage to find a solution for that?/, but my main problem is facebook messenger crashing. Does that happen to any of you? I¨m C6833 14.2.A.0.290. THANKS!
Oh, I think it actually might be due to a microphone not working properly, I am on UK C6833 with the lates firmware update. Just run the device test and it is showing me that "microphone failed" every time, also attempted some recordings and there's no sound. Does anyone else have a problem with mic? Should I have it replaced?

AFAIK, the device test tests the hardware connection itself as well as drivers etc, so if it's failing I think it's a hardware issue. I'd get it fixed on warranty if I were you. Who's your network?

I'm on Three UK, phone from Ebay...tu du dun duuunnnn...But alas, I've found out now, that it is only the facebook messenger app that messes up the microphone. It goes disconnecte and won't come back up until the reboot only when I attempt a voice recording through facebook messenger. Tried older version of messenger too to no avail. Hmmmm, mindboggling.

Have you tried Skype? I mean, you could try it and see if it works there (do a test call), and if it does, it's clearly something with the messenger app and not the hardware.
And, this thread should be in the Q&A section and not general.

Interesting... Not come across any threads on it, but sure someone else will have. Glad it's not hardware at least!

Facebook or more Apps problem with bootloader unlocked Sony Xperia Z Ultra (C6806)
After factory reset my beloved C6806 (Sony Xperia Z Ultra ) and unlocking the bootloader through the Sony official unlocking procedure, I found my Facebook, Gmail, SMS and more apps started failing to run. Especially Facebook app, it just worked once after fresh installation. After restarting the phone, the Facebook app was no longer work. The screen kept flashing several times and then exited. I was never able to make it work again.
The only way to reviving the Facebook app was through clearing data in the app (Settings>Apps>Facebook>Clear Data). However, It required login to Facebook again then worked until the phone restarting. The same symptom repeats again, again and again. I am so frustrated because the problem of instability then extended to more apps. I had also tried to install Messenger or old version of Facebook App but there was no luck at all to solve the problem. The phone started running unstable.
I originally planned to install a custom ROM and root the phone in order to resolve the problems. In that moment, I had an idea and guessed that the problems might be caused by the bootloader. The I use Flashtool and lock the bootloader.
Wow La .................. All the problems are solved and no more problem existed.
If you have the same problem with Sony smartphone and the phone is bootloader unlocked, please try to relock the bootloader again. It may solve most of your problems.
Additional note: Some people have mentioned the problem of Xperia For Facebook. This is the hint for me to think about the source of problem coming from the bootloader. Sony's default apps have a habit to check the bootloader status of the phone before running like FOTA Update. No more update is avail for those unlocked bootloader Xperia smartphones. So do not use Official ROMs if you want to unlock bootloader. (However, many apps will stop running with custom ROMs like bank apps or Google Pay.) Please install custom ROMs with unlocked bootloader Xperia smartphone. Do not keep using the Official Version ROMs because this will be your beginning of nightmare.

........calm down. You can't base your conclusion on that vague investigation.
Stock rom is so old and abandoned sony haven't added anything new to it like blocking facebook.
Yes some app developers are starting to block access to rooted devices is different ways.
There is no signs that facebook ie microsoft is blocking rooted devices yet.
But recently google is implementing only a simple block so you cant download the app from play store. But you can simply install the apk manually.
You should try something else first. Like flashing a stock rom ftf. Wiping the whole phone after the unlock including internal storage and sdcards. Even if unlocking wipes the phone.

[Q] Z2 sound problems/Root benefits

Hello buddies!
Well, my Xperia z2 is the Brazilian version(d6543) with the firmware 17.1.A.2.55, and I got a problem in the speakers.
Sometimes, music only plays on the top speaker, I noticed that after hearing a whatsapp audio recorder. And sometimes also it goes only to the top speaker when I receive a notification or when I press the "hardware buttons" (home, back and the other ). And sometimes notifications and hardware buttons sound only plays trough the top speaker.
And this really annoy me, there is a way to solve this?
Plus, which are the benefits, the problems and why I should root my z2? Will I loose something? And about that drm and the TA files? I still don't get what I should do with them.
Cheers.

55 firmware is very buggy try updating to a new FW
Rooting- an android phone has user access which means your limited to user, no system no root access, rooting alows root access meaning %100 controll of your system from inside your phone, this alows alot of modifacation, and controll of stuff such as processor clock and stuff like that
The drawbacks is it is potentialy unsafe as you can damage your phone from it
Unlocking your bootloader wipes your TA which your TA contains useful UNIQUE things about your device such as DRM KEYS
You can root your device and backup your TA, you can find what you need in the development sections

[Q] playstation app, working?

Quick question, has anyone else had issues with the playstation app since its last update??? I've noticed a couple people have, but they have unlocked bootloaders but i dont really see anyone else saying it doesn't work, just wondering if the update broke the app or if its because i have unlocked bootloader, for now im just using previous version, but if i update it i just get an error when trying to sign in
Anyone?
How has this had 100+ views and not one answer?????? lets try another way, is anyone with a locked bootloader having issues with the latest version of the playstation app?????
Because 100 viewers were looking for the answer

lol, well the only answer i seem to be able to come up with, is that latest update introduced some kinda drm, therefore i cant access it as i lost my drm folder ages ago
It's pretty much been confirmed from Sony themselves DRM is lost when bootloader is unlocked
No DRM no PlayStation app or remote play
For what reason who knows just to punish modders

Nah the only thing i lost from unlocking was xreality........... video unlimited worked, noise cancellation, music unlimted, all the xperia apps even the playstation app worked until the other day
I knew full well id lose drm by unlocking, but at the time that didnt affect anything i used including anything related to ps4 or games in general
Yeah PlayStation app worked for me also but looks like in the recent update that enables remote play they have blocked unlocked bootloaders
Try and find an old version of the PlayStation app will most likely work fine

Bro if you unlocked your bootloader you're screwed. If it's throwing you error codes, you can't login or connect to remote play. My bootloader is unlocked, xreality works, everything works. But I asked in the Sony Xperia forum and they confirmed that since I unlocked bootloader my Playstation app isn't going to work and remote play isn't going to work. Tried relocking and still no success. One you lose those original keys phone is done. What a price to pay for wanting to customize your phone you paid for your way.

Oh dear....... ta folder is where drm keys are located, if you dont back it up before unlocking bootloader its lost forever. When i unlocked mine it wasn't possible to root it beforehand, so i dont have drm keys and im thinking this is why remote play isnt working.

not neccasarily, i still have option to switch it on and off, but it does nothing.
To test, take a photo, then go and switch xreality on, go back to album and take a screenshot of the photo you just took, then turn it back off and take another screenshot (of photo not screenshot)......... if its working the 2 screenshot will look slightly different, if not they will both be the same
so is it imposible to get it working?
ok so then is imposible to get remote play working???

I'm locked bootloader, running stock RU, ps4 remote play works great, then stopped working, it was super su that broke it, Google play restored it to my phone, I know I wasn't rooted so I deleted it, and to my surprise ps4 app worked again, so I downloaded super su again and yes the error for remote play happened, so the app must check for root apps before launched
Ps
Also screen shot is not allowed while using remote play, because of legal reasons, maybe that's why not allowed rooted android

Thank you, will have a look. I never really missed anything lost from bootloader unlocked, but this remote play would be a very useful app for me, it would get used daily, there has to be a way around it. The annoying thing is i cant get it running on a device its supposed to work with (because i unlocked/rooted) yet others with non sony phones can run it if rooted

Nope nothing in that threads any good either, they cant have tightened up there drm apps thats well, looks like the only phones that cant get it running are unlocked xperias
My BL is unlocked as well, so just went ahead and ordered another Z2. It'll be coming in today, so I'll see how remote play works on an untouched/unrooted phone. I'd still like to root (without losing the DRM keys this time), but it worries me that root and / or SuperSU is breaking remote play again.
The newest Playstation app won't log in with the 8003 error.
However, if you run an older version, it will login to PSN.
As for Remote Play, I am getting the same error as the OP. Perhaps the newest apps relies on calling the DRM keys?
