"oem unlocking" option missing

So, i have a HTC Desire 526G dual sim, and i want to unlock the bootloader (to flash TWRP and preferably Magisk).
Now, my "oem unlocking" option is nowhere to be found in the developer menu. Can this be fixed somehow?

SM-N9750 bootloader unlock issue

I've had an unlocked Snapdragon Note 10+ sitting around for quite a while doing nothing (it was powered on much of the time) and finally decided it was time to give it the gift of TWRP and Magisk. After enabling developer mode, the OEM unlock toggle was present, and seemeingly was reflected on the download screen:
Code:
OEM LOCK : OFF (L)
The bootloader welcome screen was shown in Asian characters, so I initially didn't realize what was going on, but in each case, my attempts to flash TWRP failed with the booatloader indicating it was blocked by the OEM lock. I ultimately did a few factory resets to see if they would have any effect. In some cases after factory reset, the OEM Unlock setting in developer options was present and in other cases it was not. However, in each case where it was missing, I was ultimately able to get it to appear by manipulating a combination of date/time and software update settings as described in numerous posts and articles.
What I didn't realize was that the Asian language welcome screen was simply asking me to press volume up to enable custom image flashing. After realizing this, my impression here is that the OFF/ON refers to the bootloader's interpretation of the OEM Unlock status, and the (L/U) refers to whether the user pressed volume up at the welcome screen (unlock to enable flashing custom images) or something else (leaving the bootloader locked).
However, now regardless of the OEM Unlock setting, I always see the following on the download screen, depending on whether I press volume down on the welcome screen:
Code:
OEM LOCK : ON (L)
or volume up:
Code:
OEM LOCK : ON (U)
I also see:
Code:
RMM STATUS : CHECKING
So, what's going on here? Did I just earn myself a 7-day RMM lockout, or is something else going on? I thought that 7-day lockouts were indicated by an RMM status of "PRENORMAL". How can I can get the bootloader to unlock properly?
The software build currently on the device is N9750ZSS2ASKB.
Thanks.

It's not though. It's on "CHECKING". What's blocking my installation of TWRP?

And more specifically, why isn't the bootloader OEM lock status message following the OEM unlock toggle setting in developer options?

I don't know
I have
After a week (168 hours) of uptime, booting into download mode no longer results in an RMM status message. Although the OEM Unlock toggle in developer options is set to ON, the bootloader still does not reflect this, instead still indicating that the OEM lock is activated. How can I resolve this?
Thanks.
For all that wondered what was going on: the problem here was the lack of a long press of the volume up button on the bootloader unlock confirmation screen to complete the second stage of bootloader unlocking. Though this is clearly explained on the screen, this particular device features bootloader screens in Asian language characters which I sadly didn't understand.

Unlock greyed oem option help

I have a metropcs Oneplus nord n100 I'm trying to access the the bootloader but oem option in developer mode is greyed out. Also i don't own a pc is there any way i can unlock.bootloader without a pc?
There are a few devices on which the bootloader can be unlocked without the need of a PC and fastboot command sets. For example, many Samsung devices can be bootloader unlocked by going to device Settings>About Phone and tapping Build Number 7 times until Developer Options is enabled. In Developer Options, enabling the OEM Unlock option will unlock the bootloader, thus disabling the layer of protection which restricts flashing of certain device partitions. Other than Samsung, there are some device OEMs and models which also allow bootloader unlocking in this manner. However, on most devices, in addition to enabling OEM Unlock, fastboot mode must be initiated, device and PC synced with a cable, and a command line or command set must be executed.
If your device oem unlock is greyed out, you can try unlocking it using fastboot and recovery mode with the help of a pc.

Thanks i will do further research and once again thank you for taking the time to reply
Carrier-locked devices generally do not have unlockable bootloaders, or at the very least until 6 months has passed for a SIM unlock in the case with Metro going by how T-Mobile handled bootloader unlocking with the OnePlus 6T. However, that's unconfirmed and I could not find any information on either carrier-locked models for the N100 regarding this matter. So for now, it's a dead end.
yes I'm having the same issue here with the be2015 metropcs variant. They're saying 180 days (6months) till able to unlock this phone. I've been searching for some sort of way around it but no lock as of yet. Please everyone keep us all updated just in case.
when i do
Code:
fastboot oem unlock
I get FAILED (remote: 'Flashing Unlock is not allowed.
I've been trying to follow this guide here with Shizuku but I'm also running into issues. any help here please? Thanks yall
Yeah, that tuturial in the other post that the mod locked, he also deleted the commands. I'm guessing there's an issue that xda doesn't want to be involved in, kinda like writing new imei's. So I guess we're kinda screwed.
I bought this phone cheap, €117 at a discount. And Its EU version, where I can unlock the oem bootloader on this phone.
You can enable OEM unlock in Debug menu with debloat until from girhub, but you cannot unlock bootloader in metro phones.
Even if you have got unlock token, OnePlus says that's imei failed.
So is there any way to unlock this phone from carrier?

if it's metro, it has the unlock app on it; still have to be paid up and 180 days in on your account, though

Just for the record everyone:
Bugjaeger Premium - Apps on Google Play
Debugging and maintenance tool for Android devices
play.google.com
Bugjaeger Premium actually allows you to use an OTG Connection, (Android-->Android), that enables A Real connection via ADB/Fastboot.
So for all those that have no PC, but have two devices, it is possible to use one to run the ADB or Fastboot consoles and run authentic commands. I use it all the time since a desktop isn't so portable.
It takes a little thinking when it comes to the directories used, but I've easily ran Fastboot oem unlock and flashing commands before on the go

Tell you the truth, I was in the process of switching out SD Cards in the BE2015 and while I had the SIM/Tray out I saw that the developer options allowed the OEM Unlock toggle to be switched....
The option greyed itself back out once the sim was reinserted, but, I was able to toggle the switch ON before it did all that.
And even greyed out the option remains switched ON now.
For the record.

Hi! I have a Motorola G60, I opened the bootloader, but couldn't find any modified ROMs for it. I didn't change anything, I didn't root.
How to lock the bootloader?
Fastboot oem lock?
Unlocking the bootloader probably removes Widevine L1 support right. So, does relocking it get it back from L3 to L1?

[SOLVED] Galaxy A50 missing "OEM Unlock" in developer's menu

I was missing OEM Unlock option in the developer's menu. There are instructions online how to get that option to show. They won't work if you didn't do one thing. What they are all missing is that you must also let your device finish setting up completely, preferrably with your Google Account. Only then OEM Unlock will show up. So internet access is required, WiFi sufficed.
me too
