3 moths ago I have bought this device from the person, which said to me that the device is a Developer edition. The device had pure lolipop on it.
The device could be unlocked just using fastboot oem unlock. I have unlocked the bootloader, flashed couple of roms but I needed to get back to stock because I needed to send my phone to the waranty because of the camera isssue. So I have relocked bootloader and restored backup and send my phone for repair.
In the servis they have succesfully repaired my phone and send it back, but with HTC Sence kitkat rom on it. I have asked them why and they said that they had this phone in database as normal edition. I have tried again to unlock the bootloader using fastboot oem unlock but it was inpossible. I needed to get the token from the htc webside to succesfully unlock my device which I found really strange.
How it is possible that one time, device can be unlocked using fastboo oem unlock and second time not?
PS: It should be in QA thread, sorry ...

Only GPE variants of the M7 can be unlocked using "fastboot oem unlock" all other variants must use HTCDev.com. The stock developer edition have its bootloader factory unlocked.
Developer Edition M7 are also running Sense, the only variants not running sense is GPE.

Phone was probably a converted GPE edition. Then they have restored the original version on the phone, including the corresponding bootloader which can not be unlocked using "fastboot oem unlock"
My redmi 4x (santoni) have twrp installed and I it is running on miui pro rom. But it's bootloader locking automatically after enabling usb debugging and switching off the phone. I can't boot into recovery and system, can only boot into fastboot mode, and I have to use mi flash tool to unlock bootloader again.
If someone face this problem, is there any solution of this. Please reply.
Thank you.
Bootloader can only be locked on all available official MIUI ROM, it can not be locked on modified MIUI versions.
There is no way that it'll get locked by itself by turning on USB Debugging and switching off phone. to lock unlocked bootloader one has to clean flash from Mi flash tools and needs to select lock bootloader before flashing.
I don't know how are you able to unlock bootloader on Mi flash tools because to unlock it official way one will need Mi unlock tool with permission from xiaomi(depending on region)
First make sure you are not on fake MIUI if so then flash official one through mi flash tools and then unlock it by mi unlock tools.
Once it is unlocked as i said earlier there is no way that it will get locked itself unless you choose to lock via mi flash tools.
about unlocking again
sorry for mistake, I have to use mi unlock tool again with my mi account signed in to unlock the bootloader again. And can't unlock by fastboot command "fastboot oem unlock".

I still do not get it what exact issue you have and what version of MIUI you are on.
You are saying you are on MIUI Pro and that confirms bootloader is unlocked and now you are saying

I have a similar issue and came across this thread, usb debugging suddenly stopped working, it was working perfectly till yesterday. So when I went to developer options, I saw that the OEM unlocking option is clickable now ( it had remained grayed out ever since I unlocked the bootloader ). The Mi Unlock status option tells me that phone is locked. Toggling usb debugging is not making it work. When I restart the phone, I definitely see the unlocked padlock icon on the boot screen. So I am not sure what is going on. also, magisk is working fine.
In the screenshot you can see that it shows the device is locked. But from the status bar you can make out that exposed is working. I'll have to get another device though to get a picture of the padlock icon though.

Toggle OEM unlock enabled doesn´t mean that the device is unlocked, it only means that the bootloader can be unlocked, there is other item just lines after to check it; Mi Unlock status, enter to it and confirm it.
Also, you can confirm the bootloader status through fastboot with fastboot oem device-info

Yea as I mentioned, the mi unlock status tells me that phone is locked.
Just check via fastboot, and it shows that phone is unlocked.
So do I just believe fastboot, or wait a month and then try to again unlock the bootloader via the mi unlock tool?

You said "In the screenshot you can see that it shows the device is locked" but unfortunately the screenshot didn´t reveal that, I wonder, what exactly it says in the Mi Unlock status apart.
In older days, users share an aboot image, this served to unlock bootloader automatically without make the official process to unlock it, it could be that you flashed the official stock images, and it got re-locked. Anyway, we don´t know what happened with the fastboot command or with the Mi Unlock status section, so no respond to those points.
For the part you say to wait a certain time, definitely, no, the bootloader process is not monitored any more, for older devices, they can be unlocked instantly.

My phone is about a month old, so it does tell me to wait. Contradictory screenshots attached below. After the boot unlock, I did flash flash a magisk edited boot.img and vbmeta.img to disable it. If I remember correctly though it was fine after that.
That's right, you read it right. i unlocked my Verizon Pixel 3 XL bootloader
Android 10 has beta sign up. So I signed up and started the update download. I did NOT install the update. Then I checked my developer options and Unlock Bootloader was accessable.
I checked unlock bootloader and was able to follow the instructions here
warning do not install magyst!!! i went into a boot loop
Nice, what security patch were you on while you triggered the OEM unlock Option? July, August patch? Just curious

Unfortunately, if you have a Verizon version of the phone, you can't unlock the bootloader. Only unlocked Google versions allow it.
I have a Nokia 4.2 and found it pretty easy to unlock with fastboot oem unlock.
However, I've seen posts from previous years with people struggling to open the bootloader.
Is this because the bootloader lock from Nokia expires after a certain period of time?

There is nothing like that. Just connect your phone to ADB and Fastboot and boot into fastboot mode.
Then type fastboot oem unlock to unlock the boot loader

Yes now but I see posts from a few years ago saying it was locked. Did HMD Global change this in a firmware update?
If so does this mean that newer phones will get unlocked after 2 years or when warranty ends?
