Is there any chance to lock again my bootloader?
Unfortunately, you cannot relock the bootloader.

No, unlike the old Z1/Z2/Z3 where you can easily lock and unlock the bootloader, you need the DRM keys. However, even if you have the DRM keys, you still cannot relock the bootloader. I backed up the DRM keys of my Z5 before and couldn't relock the bootloader. Basically once you unlock, you can't go back.
May I ask why you want to relock it?

I feel like there is no stuff for unlock the bootloader and the f****** green pictures when you make any update of software I don't really like it

Well, there's AOSP 8.1. You can try the 4k all the time and the 120hz refresh rate. Though I'm not sure if that's fixed yet.
The DRM fix still works for me. You can manually flash the drmfix and not have to use xperifix.

I know Sony cannot not change their DRM because if they do it they can make I big mistake like giving the DRM in their software and fix any unlocked phone
And for the aosp is for single SIM and doesn't works fine in dual SIM

His guys just got the xzp and wow what a phone my only concern is root I have a locked bootloader and it's not unlockable but to be fair I've never unlocked a Xperia bootloader due to loosing drm keys etc
So my question is will we be able to get root on locked bootloaders like we did with past Xperia phones or are we stuck unless we unlock which in my case would mead no root ever :crying:
Thanks
Probably not would be my guess. You still need to unlock bootloader on previous models such as XZ/XZS.

In service menu it says unlock bootloader allowed no but in developer options it give me the option to unlock the bootloader does this mean it's possible for me to unlock the bootloader

One question if I stay with the xzp cam I at least flash the latest stock UK unbranded room with a locked bootloader so I can get rid of my carrier stuff thanks

Like always, if a security breach is found on Android that allow getting root access, it will be possible to backup the DRM partition, then after if you like, unlocking the bootloader and then restore your DRM partition.
At least, it finished like this for the Z5, but you had to downgrade to Lollipop to get root access.
AFAIK, there is no known way to get root on Nougat today.

So there is the Dirty Cow exploit that seems pretty pervasive and promising.

EDIT: Nevermind I'm an idiot, I didn't realize the dates on dirty cow.
Question still stands though, do we know if there is anyone on the XZ Premium working on it?

It's not possible anymore. You really need to unlock the bootloader in order to root. Something about patching the kernel.
Any one know how to relock the bootloader for a xperia xpz?
If you unlocked because you wanted root or custom firmware and lost the sony features for camera and want to revert back. You cannot do so until there is an drm fix or if you had your ta backed up. relocking will do nothing.

What warranty? As soon as u unlocked the bootloader the warranty is no longer valid as per the terms and conditions u read when u done it
But when you do backup of DRM keys first of course if it possible. And restore them before give Phone on warranty. And relock bootloader warrianty will be works. But if you lose DRM key without backup. The bootloader not be relock.

Basically we can root now. I think you can just relock the bootloader (to remove the unlocked message on boot thing) if you're going to send your device in for repairs.

I bought a XZ Premium locally second hand. THe phone worked great. I used Flashtool to stick EE firmware on as it had vodafone.
The thing is the camera does not work. when I select camera it shows the view. but when i press the button to take the shot ti does nothing, also the same with videos.
Snapchat video works?
any help?
UPDATE
OK so did the systems test and when I take a photo on front or rear camera it is green.
now looking online its something to do with DRM and unlocing the bootloader
I dont think this phone has been unlocked , the service screen shows as unlock possible - no
Seems like the phone has it bootloader unlocked you should flash drmpath thats the only way it will work.

For green photos you have to flash drmpatch which you will need unlocked bootloader and twrp installed. I'm not sure if it's possible but probably the owner before you relocked the bootloader?

Hello. I bought a used Xperia XZ2 compact, beautiful. But the quality of the photos (especially in the dark) is bad.
I have the doubt that the old owner had rooted the device or unlocked the bootloader, losing the DRM keys, causing the bad quality of the photos.
Is there a way to understand if the DRM keys are still on the phone?
I tried to access the hidden menu by typing *#*#7378423#*#* and in Service Info -> Security appears as in the attached photo.
Do you think the DRM keys are there?
Could someone take a screenshot on his XZ2 Compact with the DRM keys?
Thank you.
What stands in the service menu after bootloader unlocked ? If there stands like this : bootloader unlocked: yes
Then its unlocked for sure. And that stands under configuration

Yes your DRM layer looks perfectly fine/functional.

If it was lost before I do'n't know because I bought the phone like new but the drm keys was provisioned and in other threads I read that this mean the drm keys are still there.. Of course the camera quality still is the same but sony removed this "function" (and for "this function" I mean the fact that if the drm keys are lost your camera won't works) with Android 9 and I already tested this with the XZ1 compact.

I didn't say that.. I said that unlocking bootloader on Android 11 on my XZ2 compact didmn't break the camera and seems that the drm keys are still there. Furthermore Sony has removed the drm keys camera dependency since Android 9, so if you run Android 9 or newer you camera will still work even if you will unlock the bootloader.

I think that they will be wipe because when you flash a rom you need to wipe everything but you can make a backup before doing some destructive operation. But I'm not sure about the backup and other stuff to preserve the drm keys...

@raiprasant62 it is VERY CRITICAL that you have the correct stock ROM variant for your model installed before relocking bootloader or it'll lock and give a corrupt device warning and fail to boot!!!!
The ONLY safe way to relock bootloader is to use Motorola Rescue and Smart Assistant tool and then boot into the ROM and then attempt relocking
Has anyone successfully relocked the phone and checked Widevine L1 status after relock?
I read somewhere here that once unlocked.. this phone can never get L1 back and is stuck on L3 forever. But I can't find where. I wonder if it's speculation or has anyone actually tried it?

is there a fully working TWRP build available for this device which can backup /data? if yes then backup your data -> relock the bootloader -> boot into system and see what will happen.
As far as I know, there's no working TWRP currently, but I will keep looking. I haven't seen anyone talk about using it.
I did find this, from here, but I haven't found anyone talk about the pros and cons or if it worked or not. My phone hasn't been unlocked yet, because I'm unsure if I will get L1 back if I ever relock it. If I unlock it, I'll test a few of the ROMS on here out and see what happens.

that's all I could find, too. but it's unclear if it's able to decrypt & backup /data.
I assume it would be possible to bring back L1 since it depends on your verified boot state. it's like the Play Store certification I think.

Yeah it seems so.
Like you said in post #5, it seems the most important thing is to make sure to have correct version of stock rom installed for correct model. Outside of that, it just seems there aren't many people relocking in order to confirm it. But it seems like it should work like with any other phones. I've seen other Motorola users (for other models) that it relocks fine. I'm not sure where it came from that this phone can't do that, maybe it was a misunderstanding.

some Moto's will never get back the state of "oem_locked" once they were unlocked. maybe that's the reason. but it doesn't effect the verfied boot state.

Interesting. I've been outside the world of Android stuff for a few years and have been relearning everything, or some new things that have changed.
Is there a way to check the state of these things via an app or rooted file explorer or are this things inaccessible to us, in terms of modifying or viewing them?

I don't know how to check that but after relock I was able to use Google wallet without any hacks. Also unlock again was not a problem. Now I am on stock 13 ROM rooted. That works good for me.
