Relocking the bootloader - Xperia Z3 Compact Q&A, Help & Troubleshooting

I've always used flashtool to relock the bootloader and it has gone without problems every.single.time... until now...
I want to relock the bootloader so I can use the DRM Restore Mod (I was one of the early adopters that unlocked the bootloader to flash recovery before we figure out that you lose the DRM keys :crying, but when I click the button, nothing happens, the log says that the bootloader WAS relocked but in fact it hasnt (I've tested it by trying to restore the phone with Sony official tool).
Has anyone else dealed with this kind of issue?

I need help! I unlocked my bootloader and rooted my phone. But "Rooting stat Unknown"
Well now I know that I made a big mistake. I guess that sony made a hard brick in my phone. I am not sure if i will be able to unlock my bootloader again and I need information about it. I lost my DRM Keys and I can't take pictures, so It's driving me crazy.
Can I use a back up of DRM Keys from another locked Z3+?

You can't use drm keys from another phone. Plus you need root to backup your keys. And you cannot root z3+ without unlocking the bootloader first. Ive unlocked my bootloader. I have zero issues. Everything works great. What exactly did you do?

Not is my case. I rooted and later I touched "My xperia protection" and the phone didn't respond any more. Later I understood that it was a big mistake. I had to restore my phone with sony companion and now I don't have unlocked my phone and I can't root it , again. And also I lost all my DRM keys, so my camera is a disaster. I'm not sure about if I could restore the original state of the phone, locked but with the posiblity of unlocked again. My rooting status is Unknown.

Does unlocked boot loader prevent OTAs? (phone is no longer rooted)

My bl is unlocked, but my phone is no longer rooted since I used Flash tool to flash a stock FTF (23.4.A.1.264).
Will my phone accept OTAs when the next release comes along, or is the unlocked bl a deal-breaker for OTAs?
Thanks.

As long as the bootloader is unlocked, your device can't update via OTA.
For relocking you need to restore the TA-backup you did the first time you rooted, in order to restore the DRM keys lost with the unlocking process.
If you don't want to (or just if you can't) restore them, you can relock via Flashtool pressing the "BLU" button.

O.K., thank you, istux. Your information, as always, is invaluable.

Re-lock bootloader

Hi,
Some time ago I unlocked the bootloader and rooted my device. Didn't know it was possible to root without unlocking the bootloader (yes, i'm quite new to rooting etc.). Now my phone has a defective headphone-jack and I need to send it on repair. Anyone know how to re-lock the bootloader so I still have the warranty?
Currently running sLIM 4.8 by Wajk.
Use flashtool
Thanks, but it says on Sony's website that the phone stays unlocked even after using flash tool?
Code:
fastboot oem lock
Never done it in Sony phone but most of HTC, Nexus and few other brands I'm locking just with this command.

Does re-locking bootloader bring the phone back to 100% factory state?

I know that for some phones, e.g. some Sony phones, if you unlock the bootloader, it will permanently delete some stuff from the phone (DRM keys and whatnot) and you can't get it back even if you re-lock and flash a stock ROM. Is it similar for Xiaomi? Or can I re-lock the bootloader, flash the stock ROM and make the phone 100% functional and indistinguishable from one that was never unlocked?
Yes.
no problem

How to go back to stock and relock the Bootloader?

Hello
i have to sell my device so i want to get it to stock again.
My current Setup:
Bootloader Unlocked, Stock Recovery, Rooted with Magisk, Stock ROM 9.0.0.283
What are the Steps to go Back to Stock and wipe everything?
Ive read that if the bootloader relock again it is not able to unlock the second time? Is this correct? I want to get the Unlock Code to the person who buy it but if its real, he cant use the code anymore..
anyway is it possible to do the job with the Stock E-Recovery in the current state of my phone? Without bootloader Relocked? Or is it necessary to relock the bootloader again?
Thank you very much

Ask the buyer if they want it locked. Personally it wouldn't be worth my time if it couldn't be unlocked again. Better to check first..
If you want to lock (not relock) bl justdownload your adequate firmware from androidhost.ru and flash fw using Usb-otg method.
You can unlock/lock your bl using unlock code anytime you want (provided you haven't changed your mainboard in the meantime).

I thought you wanted to go back to stock. I've already gave you solution to bring back all the way stock.
I m not sure if it's even possible to re-lock bootloader using fastboot when you're on pie.
Bootloader status re-locked still means your warranty is void.

Hey I've tried this otg method but without success
If I try it with the dload folder option and try to force flash the emui updater throws an error.
Even with the dialer code method.. same..
I'm not able to get it to stock.
I've tried the Huawei suite on PC and phone in fastboot mode..same..massage this phone can't be reset or so..
What can I do next?
Current state, halfway working phone that's boot into os 2 times from 10 reboots.
