5.1.1 'Enable OEM Unlock" Method for Bootloader Unlock? - LG G Flex 2

So I just noticed today that the H950 version of 5.1.1 has an "Enable OEM Unlock" option within the Developer Options settings.
Does checking this option make it possible to use adb to unlock the bootloader? I'd do it myself, but I don't know the specific consequences of a failed bootloader unlock attempt. Experience tells me that I won't brick unless I'm actually altering files on the system partition. Does an unlocked bootloader entail altering files or is it simply a flag that is set or unset?

Sadly it is useful only to owners of lg g4 euro who can unlock their bootloaders officially
It is part of lg's 5.1.1 firmware

Samsung galaxy j3 prime sm-j327t1

Does anyone have any development on this device? It's newer and running a droid 7.0 nougat. Any root info or bootloader unlock info would be greatly appreciated
I too am looking, upgraded from the smj320a, gotta day love the phone just needs root do I can retire my older one.
Side note, I noticed oem unlock is missing. Haven't been able to find a reason or answer.
Yeah I seen that too. I was thinking about trying the custom recovery twrp for the galaxy emerge which has the same board and specs as the j3 prime except it's running marshmallow. If I flash it that might work but then it will trip the frp lock and the phone will be soft bricked. It's hopeless with a locked bootloader
Well, frp bypass is kind of my new found hobby. Have locked 10 devices and bypassed them all, one was a new found bypass on the lg tribute 5 running that 5.1.1. So if you frp I can help. Can we tag people in these like that crap spy social network site? Aka FB. Because I do know someone who could possibly help.
I too would also like to root this phone. T-Mobile variant.
How do we go about getting the sm-j327t1 it's own set of development threads?

I don't own this device, but according to what I can gather, it seems that FRP can be OEM unlocked, but the property is not set hence the property set to 0 for sys.oem_unlock_allowed.
For why it doesn't appear in dev settings I think is another issue. Can anyone confirm that this device does NOT have a manufactuerer locked bootloader.
Just to clarify:
OEM unlock = disable Googles FRP lock not unlock the bootloader.
If this device has a manufacturer locked bootloader then the likelyhood of root for this device is minimal.

The easiest way would be to simply remove the signature from the stock recovery image and then see if it flashes with odin. If it does the bootloader isn't locked. If it fails then it's highly likely to be locked.

That sounds promising
Yes I didn't set a screen lock as from what I've learned that's what activates frp, unfortunately my laptop has crashed (anyone good at bios pm me) but still no oem unlock and adb isn't working now, pc at work I've got android studios downloaded but I'll refrain from the lock until I can check, still don't know how to pull a signature from a stock image tho... But also in that article it States that oem unlock was enabled even tho there was no setting but they had unlocked boot loaders

Bootloader unlocked but OEM unlocking greyed out

First of all: Is it normal for my OEM unlocking to be greyed out with status "Bootloader already unlocked" on this device after unlocking the bootloader? On my pixel2xl the option is not greyed out even after unlocking the bootloader, so I'm confused.
More info: Trying to set up a Pixel 2 64GB unlocked version from google store, it came on 8.0 November update. I was able to unlock the bootloader, had trouble flashing to the latest February 8.1 straight from November 8.0, but was able to boot back into 8.0 and let it do the OTA to 8.1 February update successfully. I factory reset after updating to 8.1 February update and have been connected to wifi and have a sim card in while setting up (if that matters), and now the option for OEM unlocking is still greyed out with status "Bootloader already unlocked". Not that it really matters I guess since I want the bootloader to remain unlocked, but the fact that it's different on my 2 pixel devices makes me think I did something wrong somewhere or misconfigured something.

Nope.
To lock the bootloader, connect via USB to a computer that has the SDK Platform Tools on it, and reboot to the bootloader.
Open a command prompt in your "platform tools" folder and type:
Code:
fastboot flashing lock
This will lock your bootloader and wipe the device. I believe this also sets the "get_unlock_ability" flag to 0 (which the OEM unlock switch corresponds to).
To explain this a little more simply:
There are three components in play here.
First, there is a firmware flag that determines whether the device can be unlocked at all: "ro.oem_unlock_supported". If this is set to 0, OEM Unlocking will be greyed out and unlocking is not possible.
Second, there is another firmware flag that determines whether the bootloader can be unlocked:
"get_unlock_ability". This corresponds to the OEM Unlocking switch - off is 0, on is 1. If the switch is on/flag is set to 1, the bootloader may be unlocked.
Third, there's the bootloader itself. If the "get_unlock_ability" flag is set to 0, the bootloader will refuse unlock commands. If the bootloader is already unlocked, it will override the flag.
Hope this helps and makes sense!

how to unlock a locked bootloader ! ( oem greyed out )

So i received a american pixel 4 xl with a locked bootloader. imei starting with 35
i was able to unlock the bootloader here is the steps i took, note im in Australia.
Full OTA Images for Nexus and Pixel Devices | Google Play services | Google for Developers
developers.google.com
the firmware on the device was american,
i flashed my countrys firmware (australian) optus/telstra/vodaphone etc
use adb side load *firmware.zip*
factory reset , booted device on with australian sim,
and boom oem was available ,
(last step is to adb reboot bootloader,
and ./fastboot flashing unlock and you will see a message on pixel.
intially with the Original firmware on the device it would not unlock.. i tried factory reset
/ fastboot flashing unlock etc and it would not work...
anyhoo i have not seen anything on here suggested flashing another firmware origin so i thought this might help those with locked at&t / verison carriers, intially it was GREYED OUT AND SAID contact carrier or connect to the internet.
Hope this helps someone ! as all the forums ive swiped thru have said this is not do-able, lol turns out it is.

The firmware does not determine whether the bootloader is unlockable.
When the device connects to the Internet, it checks its IMEI against a whitelist on Google's servers. If it has been authorized for bootloader unlock, OEM Unlocking will become available.
If it doesn't, it's likely that you have a locked variant.

The OEM Unlocking toggle does not lock or unlock the bootloader itself. It simply allows you to unlock the bootloader when enabled.
If you want to relock your bootloader, you do this via ADB while in bootloader mode: fastboot flashing lock

For some reason I couldn't get into fastboot mode, "adb reboot bootloader" would just restart my device. If I booted into recovery, the "reboot into bootloader" option would just start up the phone. But I eventually found out I can lock the bootloader in download mode

Verizon Pixel 3 Bootloader unlock possible [Speculation]

Ok so I fully understand the Verizon Pixel 3 is not Bootloader unlockable but if the main thing that allows the unlock is under developer options would it be possible to restore a ADB backup of a pixel with the OEM unlocking slider enabled to potentially enable the option on the locked variant?

Samsung A03s roo issues

Hey I am trying to root my sm-a037w, fully updated.
I remember having OEM unlocked it using the developer option which is now gone completely.
I'm using Magisk to patch the AP file
Then use ODIN to flash it and it stops at vbmeta with a error.
I'm new to this and have googled alot but now I'm really stuck.
So it fails, corrupt phone, I reflash oem AP and it restarts.
I have adb and fastboot ready to go,
Thank you.

This is your problem, right here. If you closely read the Magisk installation instructions:
Unlocking the bootloader on modern Samsung devices have some caveats. The newly introduced VaultKeeper service will make the bootloader reject any unofficial partitions in some circumstances.
Allow bootloader unlocking in Developer options → OEM unlocking
Reboot to download mode: power off your device and press the download mode key combo for your device
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
Go through the initial setup. Skip through all the steps since data will be wiped again in later steps. Connect the device to Internet during the setup.
Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader.
Your bootloader now accepts unofficial images in download mode

If you can't see OEM Unlocking in Developer Options, and you see KG STATUS: PRENORMAL on the download mode screen, Vaultkeeper is still active and will reject custom images.

Yea I've been trying for the last 48 hours and I can't figure it out how to get it back.
I did have developer mode active and had seen and allowed oem unlocking, not sure when I disappeared, I think it was the latest update.
Don't know how to proceed.
Tried setting the date back , disabling system update and software update, still no OEM Unlocking.
I have read those instructions many times, I have no prior experience rooting or modding android :/
Should I reflash original firmware?
Where do I go from here?

Did you ever see the OEM Unlocking toggle after you unlocked the bootloader?
I assume you -did- unlock the bootloader, correct?
OEM Unlocking does not unlock the bootloader, it simply allows you to.
Reflashing the firmware might be a good idea. Keep in mind that Samsung is notorious for trying to disallow custom binaries on newer bootloaders. This is all speculation though, I'd need to see the error you got to have a better idea what the issue is.

Knox Guard has to be disabled by connecting to the Internet and checking for updates, and you have to be on stock firmware to do it.
Flashing the OEM firmware won't hurt anything, and is the only way to unlock KG.
Vaultkeeper is disabled by flashing the multidisabler in TWRP.

Hey thank you once again for your help.
To be clear this is how I recall the events .
1. I did enable OEM unlocking in developer options.
2. I updated the phone through the user interface.
3. OEM unlocking option dissapeared entirely after updating to android 12.
4. Downloaded XAC region firmware using SamFirm
5. Copied AP to my phone storage
6. Patched AP with Magisk, then transferred patched file to my PC.
7. Flashed BL, patched AP, CP and CSC(not home) using ODIN 3.14
ODIN said AUTH fail at Vbmeta on my PC and on the phone iirc.
8.Reflashed using stock AP to make the phone usable again.
At downloader screen I never saw hold volume up to unlock bootloader, only press up to continue. (after booting holding volume up+down+power)
Are KG and Vaultkeeper the same thing?
I guess my bootloader is locked and now OEM Unlocking option is gone.
This is the phone currently on latest firmware.
ODIN MODE reads:
FRP LOCK:ON
KG STATUS: CHECKING
MTK SECURE BOOT: ENABLE (0)
sec ctrl status (1)
SECURE DOWNLOAD: ENABLE
Baseband version A037WVLS 3 BVJ1 (bootloader version 3?)
Thanks for all the info, sorry for the messy post and not including all the info required.
I will provide you with the info you request, I do not know how to verify my KG status, it reads checking in ODIN MODE.
I am also not sure of how to identify the region firmware I need, the software version in my about phone says:
SAOMC_SM-A037W_OYV_BMC_12_0004
BMC/BMC/XAC/BMC
I have downloaded both XAC and BMC, both have worked for me.

The proper way to enter device unlock mode is thus:
Unplug any USB cables, power device off completely
Connect a USB cable to your PC, don't connect it to your phone yet
Hold both Volume buttons, do not press Power, and plug in the USB cable.
The screen should turn on with 3 options: Volume Up for download mode, long press Volume Up for device unlock mode, Volume Down for restart. Release both Volume buttons, then hold Volume Up.
Device should prompt you to confirm you want to unlock. If it prompts you to confirm you want to re-lock, stop! The bootloader is already unlocked.

That's exactly how - it tells you in download/Odin mode.
Since it says CHECKING, there are two things we need to do:
Ensure the bootloader is indeed unlocked, using the steps I gave above
Once bootloader is confirmed to be unlocked, you need to boot into Android, connect to the Internet (use a WiFi network), go into Settings > System > System update and check for software updates. This also checks Vaultkeeper/KG.
After checking for software update, enable developer options (if not already enabled) and verify OEM Unlocking is present; it should be grayed out with the message "Bootloader is already unlocked".
The proper way to enter device unlock mode is thus:
Unplug any USB cables, power device off completely
Connect a USB cable to your PC, don't connect it to your phone yet
Hold both Volume buttons, do not press Power, and plug in the USB cable.
The screen should turn on with 3 options: Volume Up for download mode, long press Volume Up for device unlock mode, Volume Down for restart. Release both Volume buttons, then hold Volume Up.
Device should prompt you to confirm you want to unlock. If it prompts you to confirm you want to re-lock, stop! The bootloader is already unlocked.

I am using the device normally and bought the phone new, using the google account i created for it , so i dont understand how this is possible.
Idk maybe FRP LOCK: ON disappears once you removed all bonded samsung and google accounts (maybe not caused by Google Factory Reset Protection but Samsung Reactivation Lock)?

No he didn't unfortunately. For bootloader unlocking and passing vaultkeeper one have to repeat that step twice, before and after unlocking/factory reset in odin/download mode.

Upgrading firmware shouldn't cause problems with OEM Unlocking or unlocking the bootloader. You've stated this a couple of times but have yet to provide any source for your claim.
FRP Lock is simply on because he has a Google account logged in, and has absolutely nothing to do with OEM Unlocking.
@Johnhek you have already connected your device to WiFi, yes? If not, you need to do so, then go to Settings > System > Software update to trigger a check. Once done, go back to Developer Options to see if OEM Unlocking is visible.
If the bootloader wasn't unlockable, the OEM Unlocking toggle would never be present. The toggle controls the state of sys.get_unlock_ability which tells the bootloader it can be unlocked. There are a couple of props that control whether OEM Unlocking is available, ro.oem_unlock_supported which is supposed to be baked into the ROM at build time, and ro.oem_unlock_allowed which determines whether the toggle is available.
I will admit I'm not very familiar with MediaTek Samsung devices, but I don't see why the process would be any different. Still, here is a guide on using MTKClient
Let's just see if we can get the OEM Unlocking toggle back and make KG happy.

There is no official information but there are rumors that from certain security patch Samsung removed OEM unlocking forcefully (USA/Canada devices).
It's also my experience with SM-T555 region DBT still not unlockable as of today.
I think it's common sense when it comes to rooting/unlocking that older android versions are easier to root.

FRP Lock is simply on because he has a Google account logged in, and has absolutely nothing to do with OEM Unlocking.

For other brands it's not possible to flash anything when FRP Lock is on. Furthermore that state means device is actually FRP locked. Didn't know about Samsung FRP LOCK ON is only information about device is ready for FRP locking, sorry about that...
nevertheless FRP lock is contradictory to OEM unlock, both together is afaik not possible (except for Xiaomi).
btw flashing stock firmware won't unlock RMM/KG prenormal
we will know more about in 7 days...

Upgrading firmware shouldn't cause problems with OEM Unlocking or unlocking the bootloader. You've stated this a couple of times but have yet to provide any source for your claim.

@Johnhek you have already connected your device to WiFi, yes? If not, you need to do so, then go to Settings > System > Software update to trigger a check. Once done, go back to Developer Options to see if OEM Unlocking is visible.
If the bootloader wasn't unlockable, the OEM Unlocking toggle would never be present. The toggle controls the state of sys.get_unlock_ability which tells the bootloader it can be unlocked. There are a couple of props that control whether OEM Unlocking is available, ro.oem_unlock_supported which is supposed to be baked into the ROM at build time, and ro.oem_unlock_allowed which determines whether the toggle is available.
I will admit I'm not very familiar with MediaTek Samsung devices, but I don't see why the process would be any different. Still, here is a guide on using MTKClient
Let's just see if we can get the OEM Unlocking toggle back and make KG happy.

You can also try disconnecting from the Internet (take out your SIM as well) and set the date back by at least a week. Or you can set it forward.

It shouldn't matter, honestly, although I generally prefer to do one thing at a time - unlock the bootloader, THEN update.
I have a feeling that the MediaTek aspect of things may be the issue here, although I have no way of knowing.

Hopefully it will be of some help to you. It's not beginner friendly - you have to install Python and compile it, but if you can get MTKclient working, you can see if it's what you need.

Reading it now, I think I can handle it, the instructions seem clear.
As for the date trick.
I tried it while connected to wifi, I dont even have a sim card in this phone lol.
Tried setting to last month, havent tried forward in time though, will try disconnected as well.
The mediatek thing seems promising, I think the sec ctrl status (1) in the download screen is MTK related...
I will let you know.
I have read in one of the linked threads that SIM card plays a role here. I recommend to enable mobile data for 7 days, although there is less hope.
from what I have learned from elliwigy one can't cheat samsung bootloader not even with mtkclient. there is however paid service for devices with DID token on download screen (afaik Qualcomm only). but try mtkclient first it's a good exercise and maybe you're lucky and it works.

I tried mtkcient but I kept getting unauthorized handshake when trying to connect phone :/
Followed instructions as per link but I encounter one error in the process:
Get latest UsbDk 64-Bit​
Install normal MTK Serial Port driver (or use default Windows COM Port one, make sure no exclamation is seen)
Get usbdk installer (.msi) from here and install it
Test on device connect using "UsbDkController -n" if you see a device with 0x0E8D 0x0003
Works fine under Windows 10 and 11
I'm on windows 11 and when I put the command "UsbDkController -n" in terminal it doesn't recognize it.
I installed the usbdk drivers from git hub, a .msi fil, from the guide.
Another problem is I don't know how to set windows default COM Port one.
