no OEM Unlock toggle in dev options - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

as stated in the title on my s20 plus (SM-G968W) there is no toggle for OEM Unlock, its been a long time since ive tried to root and from what ive been able to pick up from googling is it may not be supported for my country or cpu manufacturer. ive tried the change date and time trick that every guide suggested and it did nothing.

What is your baseband version?
If I recall correctly, you must be on v1 bootloader (pre Mar 2021 security update) in order to be able to unlock.
See this thread on how to unlock the bootloader (paid service):

i cant downgrade to the original bootloader?

I do not believe that it will allow you to downgrade from A13 to A11. You could try and flash G986WVLU1CTLB (A11) via the patched Odin, but no guarantees. It may also wipe your phone, so make sure that you backup before you try.

Newer fastboot firmware?

I am trying to relock my bootloader but, this z2 play had Oreo update in August and a security patch later than that. None of the firmware shared on this forum allows bootloader to be locked, it always fails saying downgrade of security.
Does this mean anyone on latest security updates cannot lock bootloader? If there are no firmware to avoid security downgrade, we are stuck with unlocked?
The latest firmware I can find is OPS27.76-12-25. This is April security patch. Before I unlocked this device, it received a security patch after the Oreo update which was probably the one above.
Can we downgrade security level in order to lock bootloader with April firmware?

[CLOSED]Force Unlocking Bootloader on Nokia 6.1

Hey,
I have been searching for an answer to this for quite a while, and I've found some information. Before you start bashing me in the comments, I do know that Nokia has disabled unlocking bootloaders on certain devices. My question is, is there 100% no (free) way of unlocking the bootloader on my phone, or just in general to get root. I am running Android 9, and I do have adb (of course).
Thank!
Also interested in this ... Don't want to let someone mess around with my phone .. used to do it myself
Short answer, no. By the looks of it there are currently no free tools, etc.
Long answer, yes but not accessible for us currently. There are ways to gain root access/unlock the bootloader on every device. Currently there are some unpatched exploits (that sometimes cannot even be fixed) in the Linux and Android system that are able to root devices, etc. The last few years showed that Baseband (proprietary Qualcomm code), the RAM (Rowhammer, Rampage) and other device features are attackable. Maybe KingoRoot or someone else might implement these exploits in the following years, and we get a free utility to root devices.
Bootloader unlock for Nokia phones!

I'm quite new to this rooting stuff, therefore a few stupid questions:
I read that with old security patches, before Aug 2018 (was that still Android Pie?) it was possible to unlock the bootloader. Isn't there some way to downgrade the security patch to a version allowing to unlock?
Is it at all required to unlock the bootloader in order to be able to install LineageOS as provided by this link?
many thanks!
EDIT: Can you recommend any working alternative way to unlock the bootloader?

August 2018 would have been Oreo and YES currently you have to roll back to unlock bootloader. It's a PAID service to have this done. @singhnsk can aid you in doing this service. I as well as many others have used him to unlock our devices. You will have to use Team Viewer and let him remotely do his work.
Good luck!!
And actually, the main question is how to unlock? Bootloaderunlocker.apk dont work, it say me "google service error" help me please

You da Man! I had to try it a few times, but it worked.
Just to clarify point 3.
3. Now turn developer option on again click OK and as soon as you do you will be returned to previous menu. Immediately click "OEM unlocking", it will show a message and ask your password, (if set), and work.

Anyone know this problem ??

Hi , Hello everyone
I Have gakaxy (A705FN) . it Stop getting updates from September 01, 2019
Anyone know this problem ??
When I enter download Mod , This phrase appears at the bottom of the screen :
Reboot Recovery Caose is ((bootchecker ) rebootRecoverywithkey)#
blocked-based OTA
Supported API : 3
MANUAL MOD v1.0.0#
I understood from some forums that if I flashing it with officiel rom void warranty .
Is this true ??
Two months ago I tried to unlock bootloader , and until now I don't know whether it is unlocked or Still locked.
I tried the adb command (fastboot oem device-info) But the adb tell me that waiting for device.
Then I tried this code : *#*#7378423*#*# connection problem or invalid mmi code.
is there method exept adb and dialler phone ??

What's wrong with you!?
Where are you, xda senior
Have you checked that an update is available first?
I'm on September and no updates have been released yet. Same baseband as you.
Why do you want to unlock your bootloader? Checking that OEM unlocking box in the Developer settings doesn't unlock your bootloader.
Flashing anything on the phone will trip Knox and Void your warranty as well as prevent you from receiving updates including the Android 10 update coming this April. Your phone didn't stop receiving updates, it's just not available where you live yet. Just like waiting for replies to your post, you're impatient to get a security update that won't make much difference to your phone. My phone is on the November patch even though it's January and I couldn't care less, because I'm patient you should give that a try

I’m really grateful, thank you for responding to my topic
I Unlock bootloader in this manner
Step 1 – Allow bootloader unlocking in Developer options > enableOEM unlocking.
Step 2 – Power off your device. Press Volume Up + Volume Down and plug in your device to a PC to boot into download mode.
Step 3– Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
Then I locked it again in the same manner.
I don’t know yet if the bootloader is locked or unlocked
and how to fix this : Block-Based OTA
So... have I broken my phone?
I need help
God bless you....
Thanks a lot

This question puzzled me a lot and I did not find any answer :/
before Flashing official rom, will I enable OEM unlocking in Developer options ? or disable it .?
Does this term : ( Block-Based OTA ) will disappear or still appear ?

The other user mentioned that official firmware through Odin wouldn't trip knox which is something I've read before but wasn't sure. In any case, I forgot to mention that if you live somewhere in the European Union, a tripped knox shouldn't void your warranty. If you want to flash with Odin I do think you need to have the bootloader unlocked, but I'm not sure how you would do that.
It's time for me to end your ignorance (im looking arrogant right )
first of all you dont need to unlock your bootloader to install official firmware.
-the Reboot Recovery Cause is ((bootchecker) rebootRecoverywithkey)#
blocked-based OTA
Supported API : 3
MANUAL MOD v1.0.0# is not an error
-Block based means what it means and OTA means Over The Air.
-manual mode if just stock recovery.
-flashing latest official firmware wont trip knox/void anything.
-it's completely 'normal' that you don't have latest update if you live in an area where providers (like algeria) don't give a damn about you.
here is the firmware you should flash in order to get latest update faster than any others countries: https://samfrew.com/download/Galaxy__A70__/to3j/SEK/A705FNXXU5ASL4/A705FNOXM5ATA1/

Thank you to all who spent time developing this All in one solution!
Hi,
Thank you for your post!
I am looking at buying a Samsung SM-A716U that I think is the AT&T model, but I'll use it with "Metro by T-Mobile", since it's "GSM Unlocked".
But anyway, I am getting a little confused, because I am seeing posts about this phone (like yours) that also reference the "SnapDragon" SoC/CPU, but every one of these phones I see advertized on Amazon, for example (the eBay ads don't say who makes it), list the chip as follows;
Exybos 980 (8 NM) Octa-Core
(2x2 2GHz Cortex-A77
& 6x1.8 GHz Cortex A55)
The thing is, that I don't want to go ahead and buy it, only to find out that the "BootLoader Unlocker", Rooting method, TWRP version, your whole procedure here, the available ROMs, etc., et al, will only work on a SnapDragon version of the SM-A716U.
Do you have any knowledge on this, please?
P.S. I am open to suggestions for other phones, as long as they're $500 or less, have an SD Card slot and hopefully a removable battery. I know this one doesn't have the last one, but there is a case sold for it that has more battery built in.
Thank You!
Zeuszoos
@Zeuszoos If you buy one of the phones with the Exynos chip, you don't have to go through all of this. Those are all unlockable when you receive them. Only US bound (Snapdragon CPU) phones have this locked bootloader that can't be unlocked using standard ADB tools.

Okay, thank you. The one I bought did end up having a SnapDragon chip.
Just to be sure:
* Unlocking the BootLoader is different than if it's GSM Unlocked, right?
* The BootLoader must be Unlocked in order to Root it and install TWRP, right?
Thank You!

Only Official binaries are allowed to be flashed

hello everyone
i have device SM-G960F Indonesia
with latest modem and bootloader which is G960FXXUHFVB4
security patch 1 march 2022
developer option is = ON
OEM UNLOCKING = ON (Bootloader already unlocked)
USB DEBUGGING = ON
*in Download mode
RMM STATE = PRENORMAL
KG STATE = CHECKING....
FRP LOCK = OFF
OEM LOCK = OFF
the question is , i can't install twrp. how ?
error : "Only Official binaries are allowed to be flashed".
i've been looking to google page 2 but no solution
1. from changing the date trick,
2. using miracle box to baypass the rmm
none of them works,
i still can't install twrp, error : "Only Official binaries are allowed to be flashed"
if there's anyone who can solve my problem, i owe you my thanks.
I don't know if it applied to the S9, but most recent Samsung phones have a very particular way of fully unlocking the bootloader as such
How to unlock bootloader:
- Backup all your media, this process will delete your internal media including music and photos
- Go to developer settings and enable [OEM Unlock]
- Reboot to download mode
- When prompted, press and hold VOL + to enter bootloader unlock mode
- Press VOL + to confirm you want to unlock bootloader, this will wipe your data
- If you think the bootloader is fully unlocked, it is actually not! Samsung introduced VaultKeeper, meaning the bootloader will still reject any unofficial partitions before VaultKeeper explicitly allows it.
- Go through the initial setup. Skip through all the steps since data will be wiped again later when we flash TWRP and magisk
- Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader. This step is MANDATORY
- Your bootloader now accepts unofficial images in download mode.

Yeah it looks like the guide really covered their bases. Check download mode and check unlock mode to see if it asks you to unlock (and not lock) the device.
I've had Samsung devices in the past that required this step more than once since the first time it still gave me the option to unlock instead of locking, which means that it didn't really unlock in the first place.
Has anybody solved this issue?
