Hi, Everyone
I'm new to this community. I'm having trouble gaining access to the OEM Bootloader Unlock option in developer options. Here are things I've tried already based on what I researched before my attempt.
Android 10 is the current OS installed after unboxing.
1. Disable Automatic Date and time
2. Select a date more than 7 days prior to current date of attempt.
3. Under Settings > About Phone > Software Information. Select/Tap Build Number 7-8 times to unlock Developer Option.
4. Disable Auto Update System (Apply Updates When Device Restarts) - *This was somehow already disabled the first time I entered Developer options*
5. Under Software Updates > Disable Automatic Updates -*This was also already disabled on unboxing and it says Automatically download updates over Wifi. It does not say Automatic Updates*
6. Reboot device and return to Developer Options after booting to OS.
7. The OEM Bootloader Unlock option should appear greyed out at this point. Toggle it to unlock bootloader with consideration that it will wipe the device data.
These are the steps I've found and tried with no success in gaining access to the Bootloader unlock option. I am also certain that my device is the international model with Exynos chipset and Mali-G72 GPU. Something else to note, I did uncheck many default options tied to improving privacy on the device before attempting the steps to gain access to the bootloader unlock option. I do not know if that would make a difference. If there is any other information I can provide to get some help with this problem, please add it to your reply. Excited to hear from the community.
Did you figure it out yet (I hope so)?
I came across your question on googling the missing OEM-Unlock on my device^^
For me basically steps 6-13 from here brought up the missing option in developer options.
After unlocking I had to do this again, to be able to flash the custom recovery

I'm told that I should be able to enable Smart Lock from Trust Agents via Settings -> Security -> Advanced -> Trust Agents, and then be able to turn it on so that I can attempt to use NFC capability with my lock screen. However, my Advanced section is totally missing from the menu, and even though I have developer mode enabled, there doesn't appear to be a menu available anywhere to enable it. I've even used the search function to see if there existed a Trust Agents setting, or an setting or menu with the word Advanced in it, and no dice.
My phone is a Samsung Galaxy S5, I guess that's obvious though, and it is running 4.4.2. I literally just flashed and rooted it with Odin and TWRP AFTER encountering this issue, because I thought that the only way that I might be able to force Advanced to be enabled if its disabled somehow instead of being outright cut from my phone's software, then I might need root privileges. So, I've finally gotten off my butt, and rooted the phone after using it without a root for a few years now. Can anyone help me solve this, since I've scoured the internet and have no where else to turn to?
Update: My settings were missing as a result of my provider, I suspect. I attempted to flash Alliance OS, then successfully flashed Lineage OS 17.1 onto my phone via TWRP, and the security settings I should of had were there. I'm not sure what provider I had though, because my phones model is SM-S209L, and all other galaxy s5's have, like, G900 series numbers.
I was having trouble booting after flashing LightROM for whatever reason, so I thought it'd be best to reflash stock firmware and try again.
Unfortunately, it seems as though Secure Check is enabled, stopping me from flashing new ROMs or downgrading at all. The OEM Unlock option isn't in the Developer Settings panel, and none of the usual methods involving changing the data and time work.
Would like some advice as to what to do now. I'd rather not wait 7 days IRL just to get the option IF the option will even show.
Currently using SM-G950F, on G950FXXU4DSBA from Updato.
Secure check verifies the file for modifications if its modified you cant flash it
Hello everyone. I'm just getting my new device situated and, knowing that unlocking the bootloader often requires a factory reset, I thought to make that one of my first tasks with my T-Mobile McLaren 5G. I was able to successfully activate the Developer menu but when I went there, I found that the OEM Unlock setting was not only off, but greyed out and unable to be enabled! If I'm correct, enabling OEM Unlocking in the Dev menu is the first step to unlocking the bootloader, before connecting via ADB or using some sort of toolkit.
I called T-Mobile to ensure this was not their doing and according to their rep (after getting transferred from CS, to a tech, to a senior tech) apparently this is not something they have control over ; they can unlock the phone to use other SIMs but don't have anything to do with the bootloader, the ROMs etc. They suggested contacting OnePlus and gave me an 800 number, but I thought I'd check with the community first just in case.
Should this OEM Unlocking option be capable of being enabled? Is there a way to unlock the bootloader without this step? I'm a bit out of date on the current state of unlocking / custom ROMs and the like - is there any sort of open source GUI (or for that matter, CLI) based toolkit for easily flashing/unlocking bootloader and other tasks? There used to be some tools available for older Nexus, Pixel, and OnePlus devices a few years back but the older ones I recall don't seem to be updated since then. If not and it all needs to be done manually, do we still use the Android SDK Platform Tools (I assume you don't need the whole Android Studio or even Android Studio CLI)?
Regarding T-Mobile, there seems to be some discussion about certain OnePlus devices requiring a code from OnePlus itself via ( https://www.oneplus.com/unlock_token ) in order to unlock the bootloader? I don't remember it being this much trouble with past earlier devices (including Nexus and OnePlus)! Is this step required or is there a workaround? Regardless, even that page describes being able to toggle the OEM Unlocking setting before anything else, so something seems to be of concern. Ideas? Thanks!
The device sim unlock for the OnePlus 7T Pro 5G McLaren is hidden in Settings-->SIM & network-->ADVANCED Network Unlock; it doesn't have a separate magenta colored unlock app icon like some older T-Mobile phones do. But, the rest should be similar to the T-Mobile OnePlus 7 Pro process https://www.xda-developers.com/unlock-bootloader-root-oneplus-7-pro/
After the permanent device sim unlock is completed, the OEM unlocking option should no longer be greyed out.
The toggle to enable OEM unlocking under developer options is completely missing, and nothing seems to make a difference.
The widely-shared workaround involving changing the date didn't work.
Waiting seven whole days didn't work.
Is 168 hours uptime with no reboots necessary?
Is a Google account necessary?
Is a Samsung account necessary?
Could someone please just explain the exact set of conditions necessary to enable this option?
try connecting to wifi

I would like to find the answer, I am with this problem in a galaxy xcover pro that I need to root to use development apps, no method worked for me and even worse it was automatically updated to Android 11, I have even less hope that it will work
Is this an LTE variant?

I also have Samsung Galaxy Xcover Pro (SM-G715FN) with Android 11. On my phone the `OEM Unlocking` option appeared after using phone for 7 days and I successfully rooted the phone. I had Google account, Samsung account and automatic software updates enabled, but I don't know if it was neccesary.

thank you, i trie and coment you
The following worked for me:
1. Factory reset
2. During tablet setup:
a. connect to wifi
b. Sign in to Google and Samsung accounts
3. turn on developer mode
4. the OEM Unlock option appears!
I did not have to reset the tablet date/time.
Can I get someone with a Tab S6 to confirm the above?

TLDR: Just enable Wifi.
I bring you the answer today
I'm with a XCover Pro running Android 12 already (G715FNXXUADVG4). Before connecting the device to the internet, I absolutely wanted to prevent any further updates, as I'm going to use some variant of the xposed framework and higher Android versions make things more complicated.
So I disabled automatic Updates in the developer options (and everywhere else I could find anything update-related).
I even removed almost every app, including update apps, using this debloat script: https://github.com/khlam/debloat-samsung-android .
I have no Samsung account nor Google account.
The option to unlock the bootloader was still missing.
I changed the date from 2022 to 2023 (for some reason it was a couple of months off). I restartet the phone.
Still no option to unlock OEM.
The device told me there were updates available now (for whatever reason). There is not even a sim card inserted, yet.
Then I enabled wifi. Couldn't tell if any updates happened, didn't notice anything going on.
And then the magic happened ...
"Unlock OEM" appeared INSTANTLY in the developers menu, just after the device connected to wifi / internet.
That's it.
A friend of mine asked me to install a newer Android in his Samsung Galaxy Tab 4.0 3G (SM-T531, codename matisse3g), which is pretty old and still has a Kitkat install. So, as I have some experience with Android hacking, I got the tablet, gave it a factory reset and unlocked the Developer Options tab in the Settings app. All tutorials that I found, say that I should turn on the OEM Unlock option to unlock the bootloader, but there isn't this option in Developer Options tab.
I tried several workarounds, like setting a earlier date and time, turning off the Auto Update option (tip: there isn't this option too)... But I was unsuccessful. There is not an OEM unlock option, neither a Auto Update option in Developer Options tab, in the Settings app.
Any ideas would be welcome. BTW, I'm a Linux user, so I don't have any Windows here (besides into a Virtual Machine) to use Odin.
Cheers,
Ricardo.
Hi, these old Samsung devices don't have unlock bootloader option. Just install a custom recovery (TWRP or lineage - for this last one, to flash it through odin, you need to pack the renamed recovery.img file into an uncompressed .tar one with a random name)
