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 As soon as u unlocked the bootloader the warranty is no longer valid as per the terms and conditions u read when u done it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.

Oh well, let's hope they find a god damn way to do it. Using an unrooted phone is so uncool.

There's a hack/mod here that offers a DRM fix, but no DRM restoration. https://forum.xda-developers.com/xz...hack-mod-sony-xperia-xz-premium-twrp-t3695171
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.

No, that required the keys which are lost forever.

Ah, I stand corrected then. What happens if you DO try to relock the bootloader? It will simply fail? Or brick the phone?

Hi
I just got my phone, but missing the benefits of rooting.
Can anyone tell me how to unlock the bootloader and then root my phone?
Found a lot of links, but not sure which are secure and not to use.
Here's where you go to unlock your bootloader - http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Once unlocked, you can flash root or do whatever at that point.
Warning though, you will lose your DRM keys in this process, if you don't know what that means, do some research

Is their any way to back them up? So if I ever regret, I can get them back?
Also, is it possible or will it ever be possible to root with an locked bootloader?

You need root to backup DRM keys.
You cant get root without unlocking the bootloader yet.
Youll lose DRM keys when you unlock the bootloader.
If you cant take losing your DRM keys do not unlock and root.

Last question. I got Samsung before and I was able to update my phone with Kies after rooting. Is their any way to update Sony devices when rooted?
Thanks
Flashtool or PC Companion. I prefer the latter.

You sure? As the DRM keys doesn't matter for me, as I don't really use the camera a lot.
But when I unlock bootloader on Sonys website, it tells me I would not be able to get updates from that. But i'm still able to get them with the PC companion?
Just to make sure, as I really want android 5.0 when it comes out.

You can't update with PC companion if you have unlocked your booloader. Your phone will be bricked!

No way to know for sure until someone tries. But with the Z2, you just have to relock your bootloader (might need to revert to a stock kernel first) and then software updates work fine.

There is no need to spam multiple topics.
YES, it can be done. NO, we can't tell you how because you didn't post your phone model or Android version.

Hej robogo1982, jesi dobio moju poruku u privat?
Just as mentioned above. I dont mind waiting but just wanna ask is there anybody able to get it already? I've done some google, some pages offer a very 'detailed' instructions like just install TWRP using fastboot method then flash the SuperSU binary then bingo!! Some others state unlocking BL is required. Since to me xda is the only reliable source so I guess I will be looking for answers here.
Cheers
since the Z3+ and newer devices, root with lock bootloader is impossible at least for now.
btw, unlock bootloader is so easy for root, why not? Warranty?

Well... DRM keys thing is what i concern. AFAIK im gonna have to give up some features if i lose it so...
Btw it'd be appreciated if u could share some posts about re-locking bootloader and backing up/restoring DRM keys, especially for this new Xperia XZ.

I've been waiting for over 3mths for some progress on backing up the ta keys on all the x range(I have the xa) I don't see it ever happening to be honest and I've made the mistake of loosing ta keys before I won't be doing it again.

Hi all.
I've got my XZ since one week now, and I'm missing the possibilities of rooting my device.
My Z2 was LB, so I never could ever try to unlock my bootloader. therefore, I don't know anything about it.
I've read a lot of thread here and there, and some points are not that clear to me.
Will the procedure of unlocking the bootloader erase everything in the phone (like photos, contacts, etc...)?
Unlocking the bootloader will kill the DRM keys forever, if I understood well. but flashing Androplus Kernel will recover them, right?
Is it possible to relock the booltloader after? if yes, will the DRM keys be restored?
Last thing, to be sure of what I should do.
1-unlock the bootloader with IMEI via sony site.
2-install TWRP via adb command
3-flash Androplus kernel.
Am I right, or do I miss something?
Thanks for your help, and sorry for the noobish questions.

Hey sensei_sai,
Im unsure if unlocking will erase your data but its always best to backup everything in the internal memory just in case something goes wrong.
Androplus will NOT recover your DRM keys but kernels with DRM fixes try to replicate the features that are permanently lost as a result of unlocking your boot-loader.
In the future it may be possible for you to re-lock the boot-loader but even then this wont restore DRM keys, the only way to restore DRM keys would be to back up your TA partition (This contains your DRM keys) before you unlock your boot-loader but to do this you need root access with your boot-loader still locked.
How to backup TA
Unfortunately at this time nobody has figured out a way to get root with a locked boot-loader although a newly found exploit (Dirty cow) may help us do this very soon so if you care about re-locking and keeping your DRM keys I advise waiting until a locked boot-loader root solution is around!

Thanks for your reply.
Too bad for the TA partition.
So we have two possibilities. Take the risk of loose some features forever, but benefit of the root or wait till someone make some magic to use an exploit to obtain root without unlocking the bootloader.
Risk and go... Or wait and safe... Dilemma...

I think that the era of DRM lock is over, we've been using DRM fixes for all the latest xperia phones, the dirty cow is a bad exploit and it's more dangerous than useful.
I was unsure about unlocking the bootloader but now that I did it, I rooted and I regret nothing, the only downside of unlocking is the warranty loss, but who cares as long as the phone doesn't magically explode.

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.

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.

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?

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
