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?

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.
Hello everyone. I installed the developer preview for Android R and i'm over it. I wanna go back to stock and I tried sideloading the OTA image and I get this message
update package is older than the current build. Downgrade not allowed.
My bootloader is locked so I can't flash the image through fastboot. I need help.
May update released might want to try that one.

I tried but it didn't work.
I was on the phone with t-mobile to see if they could unlock my phone but we're having issues with the unlock app.
I miss the days of typing in a code and getting your phone unlocked.
As you have just learned, the developer previews are not the same as beta releases. With the beta releases, you can "quit" the beta program and have the old OS version reinstalled via an OTA update The preview releases have no such OTA reset ability. Therefore, you should not participate in the preview releases unless your phone is unlocked.
If the May release doesn't let you revert back, then I think the only option you will have is to wait until the beta is released. Join the beta and have it installed on your phone and then quit the beat and hope that the OTA update takes you back to stock Android 10. In theory I think it will.
you should use the flashall.bat script if you're installing the factory image. Though this will earase data. Just make sure you have USB debugging on
EDIT: I think you should still be able to unlock your bootloader
EDIT2: After reading a bit more I see that on carrier specific devices, OEM unlocking is greyed out until the phone is sim unlocked. But after you get the app working everything should work fine. Did you use another sim thats not from T Mobile?

I put a different sim on the phone and it worked but it's b/c I did the temporary unlock. After 30 days the phone will be locked again. The phone won't let me unlock the bootloader unless it's a permanent unlock. The problem is I'll have to wait 30 days for the phone to re-lock. I wish t-mobile could just give me a code...
Lucky for me this phone isn't my daily driver but I wanted to revert to stock android b/c I got an invite to test out the Ratio launcher by Blloc. It's incompatible with Android R.

Your best bet would be to just wait until you can permanently unlock it. I got mine from best buy and only recently did I bother with flashing roms on it.
I have a TMO device and had a temp unlock, and obviously it doesn't allow oem unlocking to be enabled. I DM'd TMOhelp on twitter and was able to get a permanent unlock there. They told me that I'd have to wait for my temp unlock to expire before I could perm unlock, but I didn't. If you have trouble with the app, just clear the storage and cache data for it. Once it is actually perm unlocked you'll immediately get a notification and be prompted to restart the phone. After that you should see oem unlocking enabled in dev options and be able to hit bootloader and unlock it.
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!

I'm going to keep this short and sweet. I have a Sprint S9 SM-G960U and its activation locked and been factory reset. My friend gave me his old phone after he upgraded because he forgot the lock code and does not remember what google account was used to unlock the device after it was reset from the factory reset boot menu.
Is it possible to unlock the bootloader...if thats even needed, root the device, and flash a custom rom to get around this?

AFAIK there is no reliable rooting / bootloader unlocking method available
Same question for a european SM-G960U (Snapdragon), where no "OEM unlock" option is available in Developers options.
I've just factory reset it, and am currently waiting for the tedious 7-day uptime period to pass, but am I keeping my hopes too up ??
Please share your results and whether or not it was successful. Thanks!
Well, no luck : no unlock option appeared, and the owner decided to get their device back, so I sadly don't have any result to contribue.

Bummer!!!
Dear friends! I am writing for help. I received this device and ran into a problem. I can't get an OEM item in Developer Options.
I reset the phone to factory settings, then activated the developer mode. This item did not exist. Turned on wifi, checked for updates, rebooted the device. But this point did not appear.
I tried to change the date to earlier, a month, a couple of weeks, a year. It doesn't help. How can I get this item and what conditions must be met? I heard that you need to wait 7 days. Where does the time count come from? Can this be bypassed?
I can’t even install the official firmware through Odin, because it writes about the com port. I changed the device, and on the other device it says a read error. I need to install magic, so this item must be enabled for sure.
Help me please.

Hi there I'm new on this forum but I have the same problem with my samsung s9 SM-G960U the oem unlock option is disabled and cuz the the device is either carrier locked or it have a snapdragon processor in both cases u can't unlock the bootloader cuz the carrier doesn't allow you to flash another firmware same thing with the USA model if your device has a Exynos processor then u can unlock the bootloader (oem unlock) if your device have a snapdragon processor then its a USA model and u can't unlock the bootloader
You can unlock bootloader now. I myself have G965U1, and I did it a few days ago and then installed custom Android 12 ROM.
It is paid service though, contact the author of this thread: https://forum.xda-developers.com/t/...unlock-for-samsung-us-canada-devices.4215101/
