Does unlocked boot loader prevent OTAs? (phone is no longer rooted) - Xperia Z3 Compact Q&A, Help & Troubleshooting

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.

[Q] Official Update after Bootlaoder unlock?

I have read that Sony Phones wont be able to update via OTA update once the bootloader is unlocked. I just got my HTC One and since i dont want to loose all my data, I want to unlock the bootloader right now. Will I still be able to receive the OTA 4.2 update for the one once my bootlader is unlocked?
I dont have experience with locked bootloaders as my previous phone was an old samsung that came with bootloader unlocked(not anymore).
Thanks for the help in advance.
If you have the bootloader unlocked, you will not receive the OTA.
P.s. If you will unlock your bootloader, you will lose all your data
Thank You

[Q] [HELP] Rooting & relocking BL newest firmware 12.1.A.0.266

Hi everyone!
After searching for rooting newest firmware of 12.1.A.0.266 with LB, I found that it may be impossible without unlocking my BL. So I decided to unlock BL & root it via DooMLord's method and relock again. But I have a few questions.
I heard it's important to backup my TA partition before unlocking so I do a search for it. So I found that root permission is needed for backup TA. Since firmware 12.1.A.0.266 cannot be rooted, I have to downgrade to Android 4.1 and root it by DooMLord's method. It's all OK for me.
But I need to know, if I do restore my TA backup that taken while running Android 4.1, on my newest firmware 12.1.A.0.266, can it be conflicted that lasting bootloop or bricking my device? And relocking my device will it definitely lock my BL to factory status? Please be kind to help me with these questions. :good:
Thank you all :laugh:

No restoring TA wont cause bootloop but to be extra sure you can first flash 4.1.2 restore TA and flash 4.3..

My friend,
Thanks for helping me! :good:
If I restore TA mean I'm relocking my BL. So if I flashed 4.3 again I cannot gain root access coz it cannot root without unlocked BL. Am I correct?
So how can I root 4.3, if I flash 4.3 over 4.1.2 as root is lost after flashing a new firmware.
Thank & Regards! :good:
You need to root on 4.1.2, install CWM. Download and flash a 4.3 ROM and last flash 2.266 kernel
But there are proper threads for this xD

Yes brother..... I see several threads that explaining how to do that. But I wanted to root official firmware by unlocking BL.
If I restore TA, should I relock BL after that or, first relock BL then restore TA?
Thanks!

To make it easy, unlock using flashtool. It'll automatically make a TA backup. Later when you're done flashing stock kernel you can easily click relock and it'll restore TA and relock it for you as easy as 123.

Bro,
Is that unlocking BL via Flashtool exactly same as unlocking via official Sony method? If I unlocked BL besides official method, can I relock it again successfully? And so, since official method needs to device connected with Fastboot mode, but Flachtool needs device connected via Flashmode to Unlock/Relock BL. Why is the different with this methods? Pls kindly explain this......
Thanks! :good:

Yess absolutely the same. I'm not sure about relocking it after using the official method but I think restoring the TA key actually means relocking it. Well actually you will need to fastboot on flashtool right after the flashmode. There is no difference in result. It's just an alternative way to unlock and relock. Unlocking using official Sony method is the old way of unlocking. Flashtool is just to make it easier and simpler. The result will be the same. But be sure that you make the TA backup before unlocking it for the worst case scenario not to be able to relock it

ROOTED Locked bootloader

[Q] Unlocking/Re-locking Bootloader

I used to own an Xperai Sola. Before unlocking the bootloader I didn't know that I had to backup the DRM keys so that I can get back the "Bravia Engine" and "Download music Info option for Walkman" after the bootloader was unlocked. The information that we can backup our DRM keys came 6 months after I unlocked my bootloader.
These are my questions:
On Moto G 2nd gen do we need to backup something similar like the DRM keys of Xperia Sola?
What function do we lose when we unlock the bootloader other than Warranty? Does OS/Android update still work?
Does re-locking bootloader takes the phone back to its previous unlocked state?
@Falcon G
@vinaybaboo
@bhavin192
2. You can update phone after unlocking bl if you don't make changes to OS i.e. Xposed etc.
If you update even you have made changes to OS your phone will go into Bootloop
3. Yes Re locking and flashing stock firmware takes it to locked state
@NWKENT can answer this Questions more clearly
I´m also with similar doubts. I came from Samsung-way of unlocking bootloader.
Just to ensure if get it right, If I just put root on device, I still be able to update original rom from Motorola ?
It´s a pity we can change anything with xposed (in order to keep upgradable), bcos it´s small things we get used to, and we miss on stock roms...
Thanks,

Thanks for your input.
Please @NWKENT @Falcon G @vinaybaboo can you kindly answer this question?
I guess if you wipe data and unnistall xposed and then flash stock recovery, you will be able to flash via OTA. No need to unroot

1. No you don't need any DRM keys
2. U lose nothing rather than your warranty. Ota works if you don't install custom recovery and change the kernel
3. The new locked state is different than the OEM locked one

Falcon G, thanks a lot for replying.
If the new locked state is different than the OEM locked one, then if a user wants to unlock the phone a second time, does he follow the same method he used to unlock the first time?
So, once the phone has been unlocked it is not possible to lock the phone to back to its OEM locked state?

Relocking the bootloader

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?

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.
