How to unlock the Bootloader? - Huawei P40 Questions & Answers

I saw a video on Youtube how to install Google Play and during the video the youtuber restarted his P40Lite and then I saw the warning "Your phone is unlocked and can't be trusted..."
So, how to do that? I've installed GMS and all works well but I want to root the phone.

[Q] Locking an HTC One w/HBoot 1.54?

Sorry for the repost but I have waited almost a month now with no response... Anyways I successfully changed my father's phone from a Telus HTC One Sense to the Google Play Edition. I even changed the id so it matched the google play edition GOOGL001. I managed to get S-ON and remove the root and even update his now google play edition phone OTA. Sooo the phone even thinks it is the google play edition. The only problem remains we can't lock it. We can get it to say relocked with the fastboot oem lock command but then his phone will come up on the screen saying tampered and relocked and you can't boot the device to the main screen.
So we need it to say locked not relocked. At the moment it is unlocked. Now I was following a youtube video and it told me to use revone http://forum.xda-developers.com/showthread.php?t=2314582 BUT it does not support the version of HBoot on my father's phone (whatever that is lol)... So yeah is there any way to lock his phone while keeping S-ON and the google play edition operating system on it without the root with Hboot 1.54???
If not I guess we will have to leave it at unlocked... Thanks!

OnePlus 6 is NOT rooted but can't use Google Pay or install Netflix

When I got my OP6, I unlocked my bootloader and rooted my OnePlus 6 when it was running 5.1.9. However, SafetyNet Check would randomly sometimes pass and sometimes fail for a while, after settling on failing. I was and still am unable to use google pay or install netflix. Other apps could also detect I was rooted and would not run despite me hiding root from them using magisk hide.
I recently upgraded my phone to 5.1.11 using the OTA update. This removed root, so I assumed these would start working again after the update, but they still do not. Various apps still think I am rooted and do not run.
Does anybody have any insight about what can be the cause of this, or how I can get SafetyNet Check to pass? I don't even care about root, I just want to be able to use google pay
Have you tried locking the bootloader again? Often times, an unlocked bootloader will simply cause a fail for Safetynet. Again, not 100% sure this'll work, but it's worth a shot.
Your bootloader is unlocked check your bootloader if bootloader is locked then you need to wipe your data most of devices need to be wiped after you unroot your device.
easy fix and all you need to do is clear the playstore data so that it gets a fresh start and then reboot and check the google play store settings and see if its ceritfied again.

Google pay will work if you re-lock your bootloader. Not sure about Netflix as I don't use it on my mobile.
Edit: as for insight into why, it's a security thing. When you unlock your bootloader you compromise the security of your device so certain things won't work by design.
People need to stop suggesting to lock the bootloader. It's not needed! I have an unlocked bootloader and everything works fine. You need to install magisk and clear play store data like I told you in the second thread you created.

While you do not need to lock the bootloader to use Netflix, you do need to lock it for HD playback. Netflix uses Widevine DRM and you need Widevine L1 for HD playback. If your bootloader is unlocked you only have Widevine L3. L3 will still allow you to view Netflix content, but you won't get 720p and up without L1. You can use the "DRM Info" app from the Play Store to confirm your Widevine level and use the "Test Patterns" videos inside Netflix to confirm what your max resolution and framerate are.

As said there are only two solutions, either go entirely locked and stock(ed) or do what yldlj said. It actually quite simple people.
If you unlock your bootloader, you HAVE root with Magisk and make sure you hide root for all mobile payment apps. Just having an unlocked bootloader WILL FAIL SAFETYNET CHECKS. So you either lock your bottle or unlock it and root.
The Netflix thing is if you unlock you won't be certified in the play store so you won't see Netflix to install it. If you download the apk you can install it and is it without root but your widevine security is L3 and can only playback a Mac resolution of 480p. You will have to have a locked bootloader to to playback anything 720p, 1080p and 1440p

FALSE
My bootloader is unlocked and I am not using magisk to hide anything yes I am still certified in Google Play and Netflix is showing up to download. Make sure you are in a country that supports Netflix. Netflix is not available in every country. Also my Magisk is passing safety net checks with the unlocked bootloader

Maybe something changed because it was that way but it's still the same deal for the widevine security that you cant be unlocked and be level 1 (L1) that you can't change with root or hiding anything.

You might not be hiding those specific apps but the magisk hide toggle will be enabled which is enough. So yes you are using magisk hide. anyway the OP hasn't even been replying so yes either fixed the issue it doesn't care anymore.

That wasn't his question, sure Netflix works with an unlocked bootloader... But with reduced video quality. The OP wonders if there's a way to play Netflix videos on HD quality with an unlocked bootloader. But the answer on that is probably no.

Google Play Uncertified

After coming back to stock MIUI ROM my google play is displaying uncertified. I know it is because of the unlocked bootloader or at least that's what I think it is. Now is there any way for me to make my phone google play certified again?
This warning gets triggered and thrown when an unlocked bootloader, a rooted device, a flashed custom ROM, flashed custom packages such as Magisk, Xposed, and of course, installed Gapps on uncertified devices get detected by Google Play Services. Even as small as "enabling OEM unlock" on phone can trigger Google Play Services to throw an uncertified device error on Play Store.
What I'ld try do to fix it:
Disable OEM Unlock option from Developer Options if you have already enabled it.
If you have unlocked bootloader on your phone, then re-lock it.
Flash certified Gapps.

Yes, I'm right now on a custom ROM and it is certified. Now I want to go back to stock ROM and have it certified without locking bootloader (bypass it). Is there any way to bypass it and make google think and display it as a certified?

If you're flashing stock firmware, I think it'll mostly be certified. No need to re lock bootloader (that's what I think. Point me if iam wrong !!!)

I did flash Stock Firmware, ROM and it's displayed as uncertified MIUI Global Rom (Latest version) and the play store doesn't want to update itself at all. I can download google apps through play store but the play store just won't budge.
Had to flash stock MIUI and lock the bootloader. Now everything works fine as it did before.

Question Device is not certified

The boot-loader is unlocked on my ROG 5. I had it rooted with magisk till very recently, however, I gave up root during last firmware update. Perhaps it wasn't a good idea! Since then, Google Play has been saying "Device is not certified". (Obviously, I need a certified device for GPay.)
Is it a must to have root & magisk when boot-loader is unlocked to overcome this problem? Thanks.
(I'm worried about re-locking the boot-loader because of potentially losing the ability to unlock it in the future again. So my preference is to leave it unlocked.)

Unlocked Bootloaders will always fail SafetyNet.
Magisk, Kdragon module is the only resort here.
Locking Bootloader is also a solution, but a big no - if you plan to root it later.
Thanks JazonX, I've once again gone through the painful process of activating it all. Long story short, things are working again . I've learnt my lesson (to retain root over a firmware update).
I had before unlocked bootloader after i did recovery and locked it , i got certified google play , as i read you have numerous times to unlock the bootloader
