Bootloader back to locked after debrand without me doing it. - Huawei P9 Plus Questions & Answers

Hello.
Normally after relocking the bootloader on these phones it will say relocked. While debranding my phone I had the phone bootloader unlocked and rooted, with the untrusted boot up message. Half way through the debranded procedure I had massive issues with encryption and it not letting me past which took an age to sort out.
Once I passed that I managed to finish debranding the phone, but after flashing the the new firmware to the phone I stopped seeing the unlocked bootloader message, when I hadnt relocked the bootloader. When I checked, the bootloader was locked and frp was unlocked.
Everything is working fine with the phone, receiving updates, all themes working, everything working great.
I just don't fully understand how it's relocked itself, but Instead of it showing relocked it shows the original locked, but frp is now unlocked while the phone is locked, both originally said locked.
Anyone have any ideas. ????

Same for me
Look at
http://forum.xda-developers.com/p9-plus/how-to/guide-how-to-lock-unlocked-relocked-t3465486

Did you find out why frp doesn't go back to locked Instead of staying unlocked. I only ask because my NatWest app says i'm rooted or security settings have changed and won't let me log in via fingerprint. I wonder if it's because of this. ????
Edit. If you remove USB debugging and OEM unlock it relocks the frp lock.

Good thank you for sharing it

[Q] xt1053 Unlocked Bootloader Warning on screen but not actually unlocked?

I must have missed a step when I unlocked my XT1053 last year. I never did anything with it and assumed that because it gives the the caution screen when I turn it off and back on, that the bootloader is unlocked. However, now that I decided to get down and do stuff, it's telling me via third party apps that my phone isn't actually unlocked. There's no super user app or anything. Do I need to go through the unlocking process again? I'm on 4.4.4.
Me again. I'm following the directions for rooting it and have flashed TWRP 2.8.6.0 but when I select Recovery, there's a dead android and it says "No Command."
You have an unlocked boot loader but you don't have root privelages.Also try holding down volume down+power on no command
It takes some reading comprehension but the tutorials here really are excellent. I guess I have a philosophical question: why would you unlock the bootloader without the intention of rooting the phone? I had (obviously) confused the terms.

Can you boot the phone into Fastboot/Bootloader mode? What does it say for the status?
If its LOCKED Status 0, then your bootloader is locked. If its LOCKED Status 2 (or 1), then you are "Relocked" (i.e. the bootloader was unlocked, then someone used the Fastboot OEM LOCK process to relock the bootloader). The phone will always show the UNLOCKED Warning message screen if your status is no longer 0. (As users, we can toggle between Unlocked and Relocked, but can't get it back to Locked Status 0).
Since the XT1053 can unlock its bootloader via the code from Moto's web site, you can always just follow the bootloader unlock process again, using the same unique code for your phone.
After your phone's bootloader is showing UNLOCKED Status 3, you may root by following -> http://forum.xda-developers.com/moto-x/moto-x-qa/instructions-unlocking-rooting-dev-ed-t2649738 (Step 8 IS necessary) Please be sure to use the latest TWRP fastboot IMG file and Installable ZIP of SuperSU

Since doing the bootloader unlock process is "desctructive" (i.e. wipes use data/apps from the phone), some will unlock the bootloader when they first get the phone, run with it, and maybe root later... that way when they do decide to root, they wont need to also wipe the phone and have to set it back up from scratch.
But that is the only reason I can think of why one would unlock the bootloader, and not root. At the same respect, if you don't have a phone which is branded Developer Edition, you've already voided the phones warranty by requesting the code from Moto, so, why not root immediately?

[Q] Re-Unlock the Moto G bootloader?

Hi, some time ago I unlocked the titan's bootloader and re locked it, I tried rooting it again but I get Preflash validation, so i guess I need to unlock it again, wich makes no sense since everytime I boot up the warning shows up that the bootloader is unlocked, I have tried Motorola's website for unlocking the bootloader but my phone is ilegible anymore.
What can I do?
Thanks
Never mind, I was neglecting the spaces between the strings of numbers, I have got the unlock key already.

fastboot oem unlock XD

fastboot oem lock, but still getting unlocked bootloader message

Through some miracle, I just unbricked my phone. I locked it and bricked it but then I flashed the stock 6.0.1 rom and i'm good!. I'm now at a status 2 because i unlocked and relocked it. I know you guys hate that because why relock it, but i'm returning it and wanted to play it safe.
Weird thing is I'm still getting the unlocked bootloader warning on power on. Any ideas why and how I can get rid of it? I thought for sure relocking would fix it.

This might not work with a locked bootloader, but you can give it a shot.
Download the boot logo from this thread that looks like the original one: https://forum.xda-developers.com/mo...o-maxx-droid-turbo-x-style-logos-bin-t3407046
Double click on the .exe file while your phone is in bootloader mode and plugged into your computer.
Thanks ya, I have seen that logo fix floating around for the Droid Turbo but I didn't want to try until I had at least one confirmation that it could work on a relocked bootloader. Anyone have a guess/idea/or success story?

Can you revert back to stock after unlocking bootloader?

Hello guys,
So yesterday I got this phone. i am loving it. I have heard that gcam makes camera experience even better. I am tempting to install it.
But I have some questions. Can I relock bootloader and revert back to stock rom and recieve OTAs? Or once its unlocked It can never be stock again?
Also if I manage it relock bootloader. Will it be then covered by warranty?
Hi everyone,
Today I have a big problem
I install jasmine__V10.0.8.0.PDIMIXM and after I set "fastboot oem lock" but Now my MI A2 Can't enter in OS.
I have this message on screen
"Your device has loaded a different operation system"
and another page says
"Your device software can'tbe checked for corruption. Plese lock the bootlader.
But when I check in fastboot I have bootloader locked.
Any suggestion to unlock ? I can't enter in OS.
Thanks

[SOLVED] Your device is Currupt, it can't be trusted and will not boot.

Yesterday, I was going to lock my bootloader to cell my Nokia 8 cuz' I needed money. Being the noobie that I'm I didn't have my unlock key saved anywhere. and couldn't get a new one because the stupid Bootloader unlock app doesn't work on Pie. I did know that locking the bootloader doesn't require a key. So I just went with it without remembering that I still had TWRP instead of stock boot img installed. So when I locked the bootloader the phone booted into a screen similar to the unlocked Bootloader warning screen. But it said "Your Device is corrupt. It can't be Trusted and will not boot." Instead. So now I have locked bootloader with TWRP that I can't boot into. I still can boot into fastboot mode but I can't do much Because LoCkEd BooTlOaDeR. The only sulotion is to unlock the bootloader with an unlock key Which I don't have and flash stock boot. So please help. You'll be literally saving my life. This is my first thread ever on the internet so forgive me If I made any mistakes:laugh:
EDIT: I took my phone to the service centre near me and they were able to fix it

Hello! I have the same problem! (((You were not interested in what exactly or how you should do to correct the error? And how much money did you get for repair?
Well you can use original OST not NOST and flash signed images (.NB1) without unlocking bootloader.

Only with service point authorization as far as I know. OST (and NOST by extension) usually show you a login prompt when you launch them. Service Points login to a server that generates a temporary unlock key, which allows OST to reflash the partitions. With the proper authorization, even NOST could flash .qlz files (as long as the images inside are official and signed) with a locked bootloader.
Since we don't have service point permission we have to patch the tool to ignore it (both NOST and the hacked OST). It will still try to request the temporary key, fail, and pass an empty value to the bootloader. To get the bootloader to accept the following flashing commands, you have to unlock it.
