How to acquire a bootloader unlock code? (US model) - ZTE Axon 7 Questions & Answers

I just want to root my phone and stay on stock rom, but according to the guide I will need to enable OEM Unlock, which asks me for an unlock code. How do I acquire that code (if any vendor sells it please PM me)? Thanks.

Toggling "OEM Unlock" in Developer Options asks you for an unlock code? This is the first I'm hearing of this. What software version are you on?

I'm on 6.0.1. I have actually tried many different things since the post. I followed this guide (http://forum.xda-developers.com/axon-7/development/wip-axon-7-root-bootloader-unlokced-t3441204) and right now I have a partial root that allows me to do some stuff, but not others. For example AdAway can't change the host file and I can't change the permission of it either.

Not Android version, I mean the build version. It starts with A2017U, and there are numbers and letters after it.
As for making changes, you need to disable system write protection. Check Step 8 in this topic: http://forum.xda-developers.com/axon-7/how-to/newbies-guide-to-unlocking-rooting-axon-t3496234

It is probably asking for your lockscreen unlock code. I had to use my pattern unlock to ok my choice to enable unlock.

There is no need to request any unlock code in any case. Just follow one of the many guides here. eg. http://forum.xda-developers.com/axon-7/how-to/guide-how-to-unlock-bootloader-stay-t3461165

Custom unlock method

I'd like to build a custom screen unlocker with my own unlock method (no sliding). I have different ideas, so let's just assume I'd like to reimplement the 4 digit pin unlock method at first. I've found some hack solutions, which open an app on pressing the power button. But they can't disable the home key, so I can access the phone without knowing the pin number. Some other sources claim, it's not possible without writing a custom loader. So how come, there are so many apps on the store that offer exactly this feature? Can someone please direct me in the right direction?

[Guide] How to unlock FRP for free

I flashed a B3XX ROM and got a locked FRP. Luckily, I had saved the bootloader unlock code. Here is what I did to get both unlocked again. ATTENTION: MAY WIPE ALL YOUR DATA.
1) Boot into ROM
2) Enable developer settings
3) Toggle OEM Unlock in Dev Settings
Note: if it asks for a password, try your screen unlock. If this doesn't work, go to Security settings, change your password and now try OEM Unlock with the new password. The latter worked for me
4) Now reboot to fastboot. You should see FRP Unlocked.
5) Unlock bootloader again.
I'm not sure this will work for all configs or anything. This is just what worked for me. I was able to flash TWRP after this.

Downgrade to unlock FRP lock?

Coming from GNote 3, totally new to LG devices.
Locked Verizon G6 V988T has Google FRP lock, trying to remove it.
After going through frp unlock process and getting to file manager, bringing up settings I am getting a reduced version of settings. Options are wifi and data only; and if you click more there's only bluetooth and hotspot. And that's it. So I have no way of enabling install from unknown sources, so that I can install slide.
When I use the other method where in chrome you search for a business number, hit call and it brings up the dial pad so that you can dial service menu, there's no response. Even dialing imei does not bring the imei ID number. Seems this is disabled too.
I have no idea what software version is installed currently but it seems those two options/routes have been disabled/blocked. So my thinking is to downgrade to 7.0, follow the FRP unlocking procedure. Then install TWRP, root it.
I cannot properly ID the correct older kdz file for this phone.
1-Can you guys confirm if my steps are the way to go in order to be able to unlock frp, and,
2-a link to the correct kdz version for this phone?
Took a while/couple of tries but mission accomplished.

(TMO) OP 7T Pro McLaren 5G - Bootloader unlocking, OEM Unlock setting greyed out?

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.

Galaxy Tab S6 Lite Wifi SM-P610 Exynos International model - Missing OEM Bootloader Unlock Toggle - Need Help

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
