Hi everyone !
Hope I'm not making any double post but I couldn't find any explanation for this very specific situation.
After thorough research it, it seems that most of samsung devices has a secret setting called "OEM unlock" that we have to use to do the first step of rooting the device. In some cases that setting is missing but can be displayed again by some "date settings" tricks or waiting 7 days. In some other cases which seems to be mine, the "OEM unlock" setting is simply removed by probably the carrier of the phone and can't be reinstated.
In that last case which seems to be mine, I can't find any precise information wether we can or we simply can't unlock bootloader by other way and therefore root the phone.
Could anyone enlighten me ?
Thank you very much in advance !

I assume you know that the OEM unlock toggle is in the developer settings? To enable developers settings, tap build number repeatedly until it says you are now a developer. You will need no fancy trick to show it as the lock that hides OEM unlock, only came out in oreo. I don't think carriers disable OEM unlock on Samsung's but I could be wrong. Lastly, if you get it figured out, go over here to the right thread and get it rooted. Good luck! https://forum.xda-developers.com/sa.../how-to-root-twpr-flash-a300fu-a300y-t3494362

Thank you for the answer.
You assume right. I enabled developers settings first, saw that I didn't have OEM unlock option visible, then started to look about this issue. It is quick to see that in many case, even for phone not on OREO (I'm with Marshmallow 6.0.1), this OEM unlock is missing. But based on internet available data, it seems that in most of the case there is a trick to make it visible again. It is a sort of samsung security against thief that hide this option for seven days.
The trick didn't work for me and by looking more I saw that some people seems to be facing the same situation as mine. Some suggest that it is disabled by carrier.
But I couldn't find a solution anywhere for that context.
My question remains.
Here is a more detailed explanation :
from https://www.howtogeek.com/239798/how-to-unlock-your-android-phones-bootloader-the-official-way/
""There are two kinds of phones in this world: Those that let you unlock your bootloader, and those that don’t.
Whether you’re allowed to unlock your bootloader depends on the manufacturer of your phone, the model you have, and even your carrier. Nexus phones are all unlockable by nature, and many phones from Motorola and HTC allow you to unlock your bootloader through a similar process as the Nexus.
Other phones, however–and some carriers–don’t allow you to unlock your bootloader the official way, which means you have to wait for developers to exploit a security vulnerability if you want to root and flash ROMs. If you have one of those phones, this guide will sadly not help you.
The best way to find out which category your phone falls into is to browse its section at XDA Developers. If you have an HTC or Motorola phone, you may be able too research its unlockability on HTC or Motorola’s website. If it doesn’t support unlocking, you’ll have to use an unofficial unlocking or rooting method, which you’ll usually find on the XDA Developers forums.""

The trick didn't work for you because there is no security thing on marshmallow. What carrier are you on if you don't mind telling? Samsung's aren't bootloader unlocked like other phones.

The Galaxy A3 2015 (SM-A300FU) has no OEM unlock as A3 from 2015 don't even have FRP Lock, neither it has RMM state. That means there is no lock which prevents you to flash any custom binaries like TWRP recovery with Odin. You'll only lose access to knox apps/services (because of knox 0x1), rest remains the same.

Hi !
About my device, here are details :
Samsung A300FU
Android 6.0.1
BASEBAND VERSION : A300FUXXU1CPH3
Build number : MMB29M.A300FUXXS1CQD5
Carrier was French company called Bouygues.
About bootloader lock or not, I can see on various website that many samsung are bootloader locked but can be unlocked easily by this OEM unlock option. Sometimes it is missing. Two reasons for that : Security check that is removed after 7 days or apparently permanently removed by carrier or geographic area control.
If i'm in that last case, is there any other solution to unlock the boatloader ?Or the phone is just unrootable. It seems strange to me that some phone are just unrootable.
Thanks again !

If you read @prototype74 's post it explains it quite well. I think your bootloader is already unlocked if I read right.

Hi !
Thank you very much both of you for your help. Indeed there was no OEM unlock.
Many posts talking about OEM unlock existing on that A3 and the fact that I couldn't check if it was locked or not using the two methods advised (with adb or with a special code to dial up on the phone interface) led me to stop at that step to be sure before going on.
It is advises not to root a divise with a bootloader locked to avoid bricking it.
Anyway, trusting your input I did the whole process of rooting and putting a custom rom and it's all great !
Hi I have an s9 I went to check RMM State n OEM State in download mode and there is no RMM State Prenormal or OEM Lock Yes . I'm coming here as I was about to straight flash twrp but am unsure my knowledge would tell me with them not being there those security locks are are not in place n the bootloader is naturally unlocked on on my phone I'm also going to note that it is a snapdragon I don't see that hiding the two states from the bootloader states

Do you have OEM unlock in the developer options? Also what model phone do you have (kinda important to mention the model when asking for help).
If you have the model SM-G965U or SM-G965U1 the answer to this has been well asked/answered/discussed on the forum. The bootloader on this model can not be unlocked. It can not be rooted (maybe in future, but don't expect it to be anytime soon. Samsung did a good job locking this one down). You can not flash any custom firmware or recoveries to the phone.
If you have the SM-G9650 it looks like you would need to enable OEM unlock and possibly use some app to unlock the bootloader. I am not 100% sure on the usage of another app as well as OEM unlock, but OEM unlock should be present at least.
I have the sm-g960w canadian and no oem unlock has not appeared yet but on that same note inside download mode there is also nothing for rmm state prenormal/normal or oem lock yes/no It only shows FRP Lock the the Nox guard

Best thing I can suggest is you ask your question inside the forum for the Galaxy S9 model. There are active discussions on what it is your asking... including ones you have already participated in.

No, there isn't another one but rather the one you should be using.
For some reason you posted this in the Galaxy S9+ Q&A instead of the Samsung Galaxy S9 Q&A

Yea try I see what happens for some reason my device in xda app wants to recognize my device as a 9+ over witch it actually is also had me confused thinking it was somehow a plus but my question could still be consider here as they are in ways the same device most devices when u boot into download will show rmm state n oem lock all videos I've watched on s9 n s9+ show these to index's in download mode but my device dosnt have these n I'm just trying to find out if that means my bootloader is naturally unlocked

Despite what the app does the forum rules don't exactly permit you to post where ever you feel like for any reason. Accidents happen, but trying to rationalize posting in the wrong forum is not a good thing. You have a Galaxy S9 and should be posting in that topic.
That being said all the info you need can (rather easily in fact, took longer cuz I'm on my phone doing this and making lunch) be found searching the forum. For the model you have I found multiple references to the phone not being rootable. I also found a post saying in the galaxy S9 forum the bootloader was locked, and another post saying TWRP does not support your model.
If you want to hash it out further I suggest you ask in the correct forum for your actual phone model.

Ty I have repost in correct subs n have made contact with someone who we have both determined it has an unlocked bootloader
If a mod see this please close this post as I don't know how from the app
I just ordered the s20 4g UK version because I won't be using 5g for some time and I live in the US and want to root. Can anyone confirm if the s20 is like the s10 where the bootloader was locked on US models and unlocked on exynos? I can't find a concrete answer anywhere.
On my UK model it allows me to tick OEM Unlocking in developer option. Haven't actually tried to fully unlock the bootloader yet though
Hey guys,
Haven't kept up with research on phone unlocks etc etc. I love having my phone unlocked for the true night light, youtube vanced, perma ad block across phone and other such things.
Which version of the S22 should I be going for right now to get so that I can root my phone completely? Would the Amazon Canada version work (SM-S901WZKEXAC)?
Here are the specs/details of my Fido S22 phone that just came in, that DOESN'T have OEM Unlock option on it, not sure if this clarifies anything!
Model : SM - S901W
Snapdragon 8 Gen 1
CPU : sm8450
Baseband : S901WVLU1AVCJ
Build Number : SP1A.210812.016.S901WVLU1AVCJ
https://ibb.co/3YdZhrw
@newuxtreme any luck with unlocking your bootloader? I have the same model from Rogers and no oem unlock option in developer settings.
Did Amazon build work?
No US or Canadian Models have an unlockable bootloader by default. Id suggest getting the gobal model
SM-S901B
the OEM lock is now hidden on the S22 and I believe on most newer samsungs as well. in my case I followed a dictation on the internet and it worked well
S22 s901u if you search oem, it comes up as oem unlocking under developer options

Could you provide more info on how you were able to oem unlock. I have SM - S901W and the oem unlock shows in setting search bar but NOT in the dev options itself. Please help
S901u same here. Shows up in search that oem unlocking in settings is in developer options, so the phone says. It is hidden and needs to be enabled so you can unlock this

There is no oem unlock on North American devices. The s22 wasn't capable of being flashed by token. You all are out of luck for now
The s22 cannot be bootloader unlocked. Only method was by flashing token and I don't believe te s22 was included in this.

Oem unlocking must not be removed but hidden or disabled, because if it was removed it would not show up in search and then say it's under developer options. So you must be incorrect.

@TheMadScientist is correct - Snapdragon devices are generally not bootloader unlockable.
The OEM Unlocking toggle is hidden because ro.oem_unlock_supported and sys.oem_unlock_allowed are both set to 0 at firmware build time and cannot be changed except via remote firmware update.
Hello is there any way to unlock bootloader on U1 ? theres no oem unlock in options ( changing date doesnt work )
phone is from us ( XAA ) version.
any tool ? any guide ?
No US models can have the bootloader unlocked as of now, i think. Since the S7 it's been nearly impossible for U.S. models to unlock, the S8 was unlocked only since an engineer leaked some data.
So if you want to root your SOL, might need to get an international unlocked version.
S22 s901u snapdragon USA search for oem in settings and this shows up as a setting in developer options. Is there a way to enable or unhide this setting? Because my phone thinks that it is there or something...

You are not entirely correct. We have unlocked bootloader on us devices. But his s22 I'm sure is to far updated to be able to do anything.
