I'm trying to get oem unlocking to show up in Developer Options but am not having any luck. It's a Samsung Galaxy Note 10 + running Android 10. It's the 256gb aura glow color if that matters. Anyways I've had it turned on for 170+ hours without rebooting it. Yet I still don't see any mention of oem unlocking in Developer Options. Did I miss a step? I see some people mentioning stuff to do with changing the time and stuff and I tried that in the past with no success. I just tried to check for software updates then went back to developer options and still don't see anything about oem unlocking. I have put the phone in airplane mode a few times so could that be it?
What is the criteria or whatever you need to do to get oem unlocking to show up?
It's not rooted and I currently have had it on for over 168 hours and tried checking for software update by going to settings>software update>download and install.
Help? Thank you

What is your model number? N975(?)
SM-N975U
Your not doing anything wrong and there is nothing you can do.
The SM-N975U and SM-N975U1 do not provide us with the ability to unlock our bootloader. This means we will not be given the OEM Unlock option.
But isn't unlocking bootloader part of rooting? Or is there a way around that? I mean I don't absolutely have to root it but I thought it would be cool to have the option. What's so different about this one that I can't be given the oem unlock option? Sorry if I sound irritated.. I am but not at anyone on here
Also I got this through us cellular. Maybe should have just bought it through Samsung? Model number would probably be different and would probably be able to get oem unlocking option
You should do a little more research. None of the US snapdragon Note10's are bootloader unlockable and hence, are not rootable. Doesn't matter where you purchased it. As far as I know, this is the case for all Samsung phones sold in the US and has been the case for quite a long time.

No US versions of the Note 10+ can be OEM unlocked or rooted. Does not matter if you bought it from Samsung carrier unlocked or from a service provider. Carrier versions are SM-N975U and unlocked version is SM-N975U1. It has been a very long time since you could root a Samsung US device. I believe the S6 or S7 were the last rootable Galaxy phones in the US. The Note 8 could be rooted with an engineering kernel but it was more of a hack since you could not fully charge the phone.

There's a pretty good deal on the phone, so I started thinking about it as an option. My main problem is the locked bootloader, so there would be no option to update it after Huawei decides to pull the plug. How many years of support can we expect for the device?
You can expect two major Android releases, and some security updates after that.
So is it confirmed this phone is bootloader locked for all regions? Really wanted this phone as an alternative to the s10, since I cant go without an unlocked bootloader

There is an option in the developer options to allow the oem to be unlocked. So who knows, anything can happen.
Soooo, after enabling dev options and enabling oem unlock. download mode wont allow me to unlock the bootloader itself, theres no option for volume up to unlock. Any ideas / work arounds
If you recently got your phone there may be the 7 day block on it. Which basically disables you from unlocking the phone for 7 days. There is a workaround though where you set the time 8 days behind, check for update, restart the phone, change the time back to the correct time, and then oem unlock should be available under Developer Options!
my phone samsung a50 is stuck on boot logo (SAMSUNG), flashing, wipe data reset, but it cant. Same problems stuck on samsung logo. How did i fix?
Another thing to note is that phones in America likely have locked bootloaders, especially ones on Verizon. If you have a device from a US carrier other than that it should be fine...

If your phone is a US Variant (your phone model number: SM-A505U) then it can't be unlocked. I'm guessing your's is the SM-A505U?
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 !
Do the Canadian variants of the S20 (ending with W) have an unlockable bootloader?
Can anyone with a Canadian device check if OEM Unlock is available in the Development Options?
The A505W does have an unlockable bootloader, so I was wondering..
Thanks!
Dream on, its locked. Every north american snapdragon samsung phone is locked, that a505w is an exynos so its unlocked.

I just upgraded from the s7edge which I went back to after not being able to root the s8, so I haven't really followed any of the phones after that, but will there be away to unlock the bootloader found eventually, or is this just the way it is ?

If it follows the same pattern of S8, S9, S9 and the Notes - then never.
You can always try and see if its unlockable by going into the Developer Options, check to see if OEM unlock is available. If it's there it may be unlockable.

Not to sound like a ****, but if the option was there I wouldn't be here. I just started reading into the last couple models that didn't have the oem unlock option under the developer options and I'm starting to think that the outlook isn't so good. I should have done a bit of research and maybe tried to get my carrier to grab me a phone from elsewhere and bring it in for me. Just happy I kept the s7 edge, give me something to play around with while I wait for whatever comes next I guess.
Is it possible to flash stock firmware from one of the variants that does have the oem unlock option to the phone ?

Hello everyone thank you for your time it's been a couple days i'm doing reasearch on how to root my galaxy S9 (canadian) and i'm hitting a wall everytime and some post a far too old to be considered.
So my question is without the OEM unlock option in developper options am i doomed to not being able to root my phone ?
And yes i tried the trick with setting the date manually one month earlier but anyway my phone is more than 1 year old so i'm way past the 7 days delay.
Isn't there a way to unlock it with a computer via USB debugging mode ? ( juste an idea like that i know pretty much nothing)
Any clear answer would be greatly appreciated.
Thank you for your time
OEM Unlock option is pretty much like the gate to unlock your boot loader
if your phone doesn't have the option then that could be cause by some factors like,
- either you can't unlock (I believe there are few versions that factory lock which mean cant be unlocked)
- or you have faied to modify your phone, which you have to wait like 7 days to be able to modify again
That all I know, maybe anyone can correct me if I'm wrong

okay i understand more what OEM does thank so as long as i can't unlock it from the inside no modification can come from the outside
You should read through this thread. It has some options that may interest you. The Canadian SM-G960W S9 is definitely boot loader locked that makes it "normally" not able too install any custom ROMs or boot loaders. The good thing with it is that it doesn't trip KNOX!
