Relocking bootloader? - Samsung Galaxy S9+ Questions & Answers

I can't find any questions regarding this, the closest I saw was today, about not having gotten the OEM Unlock option back.
Ever since unlocking the bootloader, it broke Google Pay and Device Certification. I don't know why Google Pay needs a locked bootloader to work. I imagine security reasons, but there are other banking apps that work regardless (Barclays has its own contactless system built in for example, and that works).
I know that enabling OEM Unlock will force a factory reset and then disappear for 7 days. I have it back and it is currently disabled saying "bootloader is already unlocked"
What I want to know is, will enabling it re-lock the bootloader or is there some other way I can do that? Because I would like Google Pay functionality back. Netflix I'm not so fussed about as APKs for things can be installed manually.

Google Pay stopped working after OEM unlock

I guess the title says it all but a little info, a couple of months ago I went on to settings and ticked on the OEM unlock option but never went forward with any flashing, no custom recovery, no kernel, nothing, plain stock Samsung ROM. 3 days ago I went to pick up some newspapers for work and everything was fine, at lunch time I had to get something and upon swiping the phone on the terminal it came up with a message on my phone that this device cannot be used to pay in stores with google pay. I deleted and updated my card info since I lost it recently and the new had a different expiration date. Which I had already changed but figured it might have taken a few days to flag or something. Same result, can't pay in stores message. Got in contact with google pay support and they told me my phone had been flagged for being rooted,modified OS. I said that I'm not rooted then they said it appears I have an unlocked bootloader so google pay doesn't work on devices with unlocked bootloaders. I stated that an unlocked bootloader is perfectly legal and not a sign of a modified OS. The operator replied they can't do anything since it's policy and my only option is to relock the bootloader, so I told them it'd work if I had a modified OS but it wont if I have an unlocked bootloader with no modifications to cover the BL state and I laughed, said thank you and signed off from the support conversation.
I went back an relocked the OEM option and restarted for it to take effect and was then able to use gpay again.
I have a XEU Exynos with the April Security update.
TLR if you OEM unlock but don't flash magisk and magisk hide your google pay wont work. Relock,reboot and you're good to go.

This was changed a while ago, a unlocked bootloader will trip safety net, if you have no reason for the OEM unlock, don't use it

Yes, I forgot to mention it triggers the CTS Profile to mismatch and thus fail the Safety Net status check even if the Safety Net Request flag itself isn't raised.
I honestly think they're just trying to cover their asses by removing functionality even though I fail to grasp that they are not aware that the people who are technically minded enough to root, and try to use the service with malicious intent, know how to bypass Safety Net checks. On the other hand it might be that if someone has an unlocked bootloader is more susceptible to remote attacks and potentially have a random apk root and take hold of their device and all their info.
It's been a long couple of days at work and while typing the original post I forgot half of what I wanted to mention hehehe!!!

Bootloader unlock/re-lock

When you do the bootloader unlock you need to wait and get some form of security info from Xiaomi itself, but then you can lock back the bootloader and restore everything to factory-like state (and you will be able to pass the most paranoid checks that you would be able to pass from factory state, obviously not Widevine L1 since you can't do that one in the first place).
The question here is if after that you want to unlock again - do you still need a link / secure token from Xiaomi (and thus you are still subject of their control) or you can do it the same way as with Nexus / Pixel or Oneplus phones in fastboot?
Since if that would be the case it absolutely makes sense to make this unlock + re-lock the first time you get the device just in order to be 100% certain that bootloader unlocking is no longer under Xiaomi's later control but your own!

AFAIK the unlocking is always through the Mi Unlocker, whether it is the first time or after re-locking. The fastboot command for unlock won't work. The only saving grace seems to be that you don't need to make a request and wait for 3 days every time. It is applicable for the first time only.

How to unlock bootloader on Huawei MediPad M6 10.8"?

Hi,
I've recently bought a Huawei M6 10.8". Unfortunately, it doesn't have Google Play (and the rest of the services). I'm trying to install it to it, tried to ask how to do it without unlocking the bootloader, didn't get an answer (probably because it's not possible). I've been reading and got mixed answers if the bootloader is unlocked I lose the warranty. I've read through the policy, didn't seem to find anything about that, so I assuming it's not the case. Either way without Google Play (and co.) the tablet is quite useless, I'll have to open the bootloader, get TWRP on and flash OpenGapps or similar.
I've been trying to follow this guide, but after issuing:
Code:
fastboot OEM unlock
...I get permission denied with Factory Reset Protection (FRP) locked. When I go the developer options, there is a grayed out "Enable OEM unlock" option, but it doesn't allow me to switch it on. I know the password and everything, but how can I disable that FRP Lock? The internet is full with options when I don't know the password (none I tried seem to work). Please help, thanks!

The official bootloader unlocking method for Huawei device was stopped by the company pretexting they wanted to guarantee a bug-free experience and that ROM-flashing and other modification ruined the experience : https://www.xda-developers.com/xda-huawei-decision-stop-bootloader-unlocking/
That was back in 2018, there are still unofficial methods to unlock bootloader, but I won't because they're all paid methods by some shady apps.
So if guess that's why OEM Unlock is greyed out, and even if it isn't, when you'll try to unlock the bootloader, it'll request a code that you don't have...
Sorry man, the moment Huawei stopped allowing users to mod their Android device was the moment I started to hate them. What is this, Apple ?
Wow sorry, I got carried away, please don't ever get me started on that lol.
Hope you'll still have a good day
Both my wifey and me have a Huawei phone in use. We use the phone as it is meant to be used by OEM. We aren't interested in modifying anything on them because they have all the features we wanted to have. We don't want to transform them to another one because we don't see any advantage in doing so. Those Huaweis for us are a tool, not a toy.
We knew what we buy.
Thanks for the info Raiz. You mention some "shady apps". Which is the most trusted out of them? Thanks
@antivirtel
To install Google Play on devices where it is missing it's not required that device's Android got rooted or device's bootloader got unlocked. If people say it has to be like this, they're idiots.
The Google Play package consists of at least 4 APKs that install as user-app:
1. Google Account Manager APK
2. Google Services Framework APK
3. Google Play Services APK
4. Google Play Store APK
Knowing this you've to download the 4 APKs matching your phone's Android version and OEM and install them . APKMirror is probably your best bet for trusted Google Play Store APKs.
After you reboot, you’ll find the Play Store and Google Settings shortcuts on your home screen. Tap “Play Store” and you’ll be able to sign in with an existing Google account or create a new Google account.
It may not appear to work normally after you sign in, but just give it some time. The Google Play Store and Google Play Services will automatically update themselves in the background. This may take as much as ten minutes.

Hi,
Actually none of them, because they're all paid method. Don't try that please. You can try what jwoegerbauer suggested and see if it works, but please don't pay something to root your phone, it is very unsafe and may be a scam (most of the time it is).
Have good day

[CLOSED] Can anyone help unlocking the phone of my father who just passed away?

Like the title says, my father just passed and we're locked out of his phone.
Don't want to factory reset the phone because all of his accounts are on there in apps and we're not able to figure out if we missed anything. Worried about upcoming bills and then any stocks or trades he did only in apps.
Currently the phone is requiring a pattern unlock and I've unsuccessfully been able to guess it so it kind of locked us out of doing anything. Can't even power off or reset it.
It's also saying "unlock the phone to use fingerprints." Does that mean even if we were to somehow guess the pattern would we still need the fingerprint to open the phone?
Is there a way we can bypass any of this? I looked into some programs and downloaded them but they all said they would erase the data if we removed the pattern unlock.
I have access to his Gmail via a tablet that we knew the pin code for but haven't been able to reset the password just yet. Not sure if having the google account password available will help us unlock the phone or not?
Any help or links to tutorials would greatly be appreciated.
By sheer luck I was able to guess the swipe unlock pattern so the phone is now unlocked for me. Mods can delete this thread if they want.

Unlockable Bootloader - options?

After rooting my Z2 and backing up the TA partition, I've discovered that the bootloader is not unlockable (it's a Vodafone branded device).
Is there a nefarious way in which to bypass this? I understand that the whole point is to keep it locked, but it's an old enough device so I may have missed where it's possible.
Otherwise what are my options for an up-to-date custom rom? As indicated, I've already achieved root and have TWRP installed. I tried flashing Lineage via recovery but got an E: unknown command [log] error.
I'm in the same boat unfortunately. I bought a used phone that had Vodafone UK. It was marked as SIM-unlocked, and that seems to be true; the service info doesn't show any filled checkmarks nor counters in SIM lock information. However, bootloader seems to be locked forever - flashtool reports "Bootloader status : NOT_ROOTABLE" and phone's service menus also say that rooting status is "bootloader unlock allowed: no".
I wasn't even aware there are Sony phones that are not SIM-locked but are still boot-locked without any way to unlock.
I would really want to upgrade from Android 6 to at least 7 because there are some specific apps that work only from A7. Wondering if there is any custom ROM that would run on stock A6 kernel but with everything else from A7? It should be possible to install such a ROM even on a bootlocked device, right?
Since posting I've discovered some answers. The bad news is that, no, custom ROMs are limited without an unlocked bootloader.
The potentially good news is that you can pay for an aftermarket SIM unlock, which has the side effect of also allowing the bootloader to be unlocked.
I've not tried it myself, but do a search for "Sony cable unlock credits" for some leads.
Yea I also am stumbling upon this same news, in my city there are some shady areas so I will ask around and see if anyone is capable of doing it and will let you know.
So far my phone has bootloader locked, sim locked with 3 attempts left so I will work on unlocking those and then rooting the phone and digging deep after
Lets cross our fingers that somethings comes up
So far online , I find only old videos and outdated information, websites down and nothing else.
One thing is for sure, if your bootloader can be unlocked, you just go to sony official website and follow their instructions and its free and easy,
But if it says ""bootloader unlock allowed: no" then...lets see what can we do.
Hey I am willing to pay, why not if its going to unlock the bootloader 100%
