Get unlock code on already unlocked (and rooted) device - Huawei P9 Plus Questions & Answers

Hi,
I have a VIE-AL10, firmware B183. I am trying to update to B195 but I believe I cannot do it because I unlocked the phone.
I don't need the unlocked bootloader anymore (for now) and my idea was to relock it and unlock it again in the future but unfortunely I have lost the code I got using DCUnlocker.
There is a way to recover the code in this unlocked and rooted phone?

U can update with unlocked bootloader but not if u have TWRP and root. If u have it i need to unroot and install stock recovery.

Thank you, I imagined that. Any way to recover the unlock code so that I can redo the unlock procedure after I upgraded the phone?

[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] Can you be rooted and have a locked bootloader

I'm interested in rooting my nexus 6. I know that you have to unlock the bootloader in order to root the phone and install a custom recovery. But after all of that is done is it ok for me to re-lock the bootloader for security reasons or will it have any issues?
Thanks in advance.

Why is that the case? I was able to unlock flash 5.0, relock and side load 5.1. Did Google change something in 5.1?

Yes. Very much so.
problem is.. you now have to enable oem unlocking, to unlock the bootloader. technically, you can still be rooted and lock your bootloader. but the problem is that some have gone back and relocked their bootloader(not with root i dont think so) only to find that they cant boot up, that they end up with a boot loop. and then they cant unlock their bootloaders to flash the factory.img, because you need to check that setting first, to unlock the bootloader. honestly, i think someone with root, and twrp, would be able to. if not, you can fix it by formatting a few things(if you have twrp).

If you have a custom recovery installed, then having a locked bootloader is no more secure than having an unlocked one...

Is bootloader locked?

I bought the Kenya version from Jumia. Is the bootloader locked? Is there anyway I can tell if its locked or not?
Also, if its unlocked, can I flash a custom recovery then root thru it?
Thanks!

Don't know??? Never try to relock it...so you have to flash stock rom and your BL will be automatically locked...

As far as I know if you are running a custom boot image you won't be able to relock the bootloader on nougat. It's a feature to prevent you soft-bricking your phone, because if you lock it and it detects unauthorised firmware it will refuse to boot.
To relock nougat, simply use the dload method to get a completely stock device and you will see that the bootloader is now relocked.

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.
