This is happening to me on a Samsung s7... I was able to install a form previously, but then I went back to the official version using Odin.
Now when I click the OEM unlock and 'Enable', the button turns itself off Any ideas?

Since you have unlocked the bootloader, you won't do it again. You have to lock it first, if possible (I have no experience with this model).

I just realized that when I boot up the phone, it shows the "Redmi by Xiaomi" and below it says unlocked, (IDK if it has any relation). But the Developer options say that BL is locked and OEM Unlocking can be enabled. What does this mean?
This is same with me miui 11 stockrom
Magisk flashing creats bootloader locked
If i uninstall magisk it show unlocked again
Even Netflix installation works by this in playstore

Well that's cos at one point you had unlocked your bootloader and might have dirty flashed MIUI or used fastboot images, which aren't able to recognise the state. But in reality it remains unlocked and it just shows locked in the settings.

Yes true. It is unlocked. The unlocked message at boot verifies that bl is unlocked.

I apologize if this is a bit too late, but I have a follow up question. Can I try to unlock the bootloader even if it's really unlocked just to connect my account to my phone or something like that?

If it's unlocked, the Mi account is already linked tho.
Even if you try you won't see a difference, maybe the unlocked symbol might come up.

Woah. Unauthorised seller eh. Are you sure you are running the Orginal MIUI? The reason Xioami started locking away the bootloader was cos of these unauthorised sellers, unlocking the device and flashing it with an outdated ROM. You should try, Go to Developer settings, link your current Mi account and then proceed to unlock. Or if it says an acc is already linked, lock the bootloader (only if on MIUI Stock, Custom ROM would lead to a bootloop), and now go link your account. (Do take backups before proceeding)

Well, I did flash the latest MIUI Indian Global ROM a few weeks back so maybe I am running Original MIUI?
But I'm still gonna try to "unlock" it. And is there an option to keep all data after the unlock?
EDIT: I just read the Mi Unlock Tool's disclaimer and how they say some features won't work after the unlock. I mean, I know mine is unlocked but I think I'll just keep those features.

Usually the first time you unlock it wipes your internal storage , but it doesn't wipe it in the subsequent unlocks (as far as I've tried). Yep it doesn't actually affect any system functions.. everything is as smooth as before..Find my device works fine as well..the only risk is that if your device gets stolen they could easily wipe MIUI and bypass that account lock by flashing a custom ROM.
Hi all,
I have a Straight Talk Galaxy A20, model SM-S205DL. Will root instructions work for this model? I don't notice an OEM unlock option in the Developer Mode menu, but I can boot in download mode. Thoughts? It's been a while since I tried to install custom firmware.

There is a trick where you change the date to some weeks in the future.

Some places claim to be able to change the CID of the phone. Would that help? I imagine once able to load different non-TFN BS firmware on the phone that magic developer option may appear. Or is it a hardware thing and the exynos chip has something to do with it? Not sure how it all works yet. Anyone know what the unlocked us retail model contains?
I'm not smart enough to find out so hopefully someone is and reads this and can chime in regarding all the points...

I have Tmobile Oneplus 8. I haven't unlocked the bootloader yet. Will I have any issues with Google pay with unlocked bootloader if I'm going to unlock it?
I'm using company secure email app on my phone as well. If I have any issues, will I be able to lock the bootloader?
I don't know about tmobile version. But i have unlocked bootloader + root on oos11 and google pay is working fine here
I'm trying stock with locked bootloader and no root for the first time in maybe 8 years, but I've always got everything to work. You tried hiding it in Magisk?

You can, with msm tool, it relocks bootloader and factory resets everything to stock.
I just received my Flip3 (SM-F711U1) and would like to unlock my bootloader. However developer options is missing the OEM Unlock option. It's completely missing not just grayed out. I read a few articles about needed to change the system date but none of those guides changed anything. Can someone help?
Also, I attempted to call *#*#7378423*#*# to double checked that it wasn't already unlocked and I got a popup saying "Unabled to process the request."
Thank you.

Have you tried through fastboot? (fastboot oem unlock)
Oh, got you. Sorry!
As far as I'm aware samsung devices don't support fastboot. I did attempt to connect it in case I was wrong but was not able to get fastboot to recognize the device.

You can try directly unlock without ticking the oem unlock. By boot into download mode. The other thing is your device or carrier or country wont allow your flip 3 to be unlock. There last step you can try is clean flash via odin with your latest firmware.

I can get into download mode fine but don't know how to use that to unlock directly. Can you give more details?
I tried a clean flach with my latest firmware but it didn't change anything.
It's a US carrier unlocked version I bought directly from Samsung. CSC of XAA. Currently using a T-Mobile SIM.

If you had them enabled on your last phone and you restored from your Google backup, developer options will be enabled. Has happened on all of my phones since Android 9

If you can boot into download mode there is an instruction just press vol up button and it will prompt do you want to unlock bootloader mine is like that. Im not sure yours since mine is korea version.

They support bootloader unlock. samsung dont support using fastboot unlock or command at all
if you're in North America, Canada etc Qualcomm chips there do not support bootloader unlocking, at least the Samsung one's don't, not sure about other OEMs.

They used to, so there was always a possibility it returned.
I recently read this article on XDA about unlocking the boot loader on the Fold 3 which results in Samsung disabling the camera (WTH?), Is this a thing on the Flip3 too?
My device is rooted. I have always been able to find the OEM unlock option under developer options without any constraints.
My camera is NOT affected. I can still use it without any issues.
I have an European device (SM-F711B).
Hope this helps some of you to track down whether this is a location or carrier based problem.
Hey Redhatter,
Out of topic question, but are you getting Tmobile 5G just fine?

I tried for my first time to unlock my phone's bootloader and thought it was something really easy to customize the
phone firmware on the other hand was not what I thought and I don't know much about computer science or customizing a firmware;
and then without being able to install a root or any modification I decided to re-lock the bootloader (because i dont want it anymore) only that I did not succeed with various tutorials and I did not find any for the samsung galaxy a12. I just unlocked the bootloader from developer options settings and ran what the tutorial said on how to activate it without installing a root or customization of anything.
can someone please help me.

Wait, is it really so hard to lock the bootloader on Samsung devices? Makes me think twice about buying one now if I can't simply lock it with a command like fastboot oem lock.

It's not hard to relock as its not hard to unlock it.
If you've followed any unlocking bootloader tutorial, after enabling OEM unlock option, you have to enter downlod mode and long press the volume up to enter unlock mode and then procedd to actually unlocking it.
For relocking it, just go to the download mode again, then long press the volume up and you'll have the option to re-lock it.

Samsung phones have a download mode instead of a fastboot mode, so you can't use commands like fastboot oem unlock
