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 I'm a bit out of date on the current state of unlocking / custom ROMs and the like - is there any sort of open source GUI (or for that matter, CLI) based toolkit for easily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.

Hi all. I have been searching high and low for information on this specific question:
Will activating an unlocked Pixel 3a on Verizon disable the OEM Unlock and bootloader unlock capability?
I got a Verizon variant before I realized that there was not way to unlock the bootloader. Bummer. So, I returned it for an Unlocked version from Google, which I just received tonight. I breezed through the setup (without the SIM card) and noticed that OEM Unlock was disabled stating I needed to connect to the internet. So, I enabled WiFi and the OEM Unlock was then available. It would seem that I an now able to follow the unlocking procedure.
My goal is to unlock the bootloader and root, but do I have to do it immediately? My concern is that activating the phone with my Verizon SIM could:
1) Prevent unlocking the bootloader in the future if I don't unlock it before I activate with SIM (research seems to indicate that factory resets will undo disabling OEM Unlock if this can happen if I understand correctly)
2) Re-lock an unlocked bootloader - maybe this is not even possible?
I don't want to mess this up. All the info I am finding are discussions related to trying to unlock a Verizon variant and I cannot find good info on what happens to bootloader unlocking options on unlocked phones that are activated on Verizon. The only reason I may want to delay this process is because I dont have a lot of time at the moment and would rather not rush the bootloader unlock and root process. However, my HTC 10 is in bad shape and need a phone to get through the holidays. I was hoping that I could activate it on Verizon now, use it with its locked bootloader for a few weeks, and when things cool down after the holidays, implement the bootloader unlock and root.
If that is not advisable, what about unlocking the bootloader immediately (doesn't seem too hard and I have used ADB before), and activating without root. Then root later? Any possibility of concern #2?
Can OTA's re-lock a bootloader and prevent future unlocking?
I appreciate anyone's incite, experience, or links to the needed information for clearing this up. Thanks you!
I would advise you to unlock the bootloader asap. If you wait it will be a pain later because unlocking causes loss of data. If you don't care about that, wait as long as you like.
As far as Verizon is concerned, if the phone is unlocked, I don't see how they could possibly lock the bootloader. They may restrict your services but they can't touch the lock status of a device you purchased.

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 have this phone (ASUS_A009 ZenFone 5 V500KL Live) and I've yet to find a reliable resource to unlock the bootloader. I sure rooting the phone won't be a problem but the bootloader has been the time consumer today. Am I just missing something here. I've done every method I ran across on XDA pertaining to ZenFone. I am about to attempt to flash firmware with an image for the only other phone similar to this one (except the VZW part). I say that because when you look up "ASUS_A009 specs" in Google you'll get the V520KL but upne further investigation I found otherwise. There is talk about the ENG Firmware Allowing for OEM unlock through fastboot. I grabbing at air here.

For Oem unlock, go to settings, then about phone, them software version and tap 7 times on that. Then go back to settings and tap on developer options. Then inside developer options, tap oem toggle. After this do unlock process with computer
It's been a while since I have beein this world. I used to be constantly flashing my phone and tablets, but for one reason or another I stopped. I've been happy with the 8 pro, just getting a little bored and a little more privacy minded. I don't seem to be able to unlock my bootloader. I tried every set of directions, different pcs, diffeent cords, nothing. I have and IN2025 from the US. The ulock the bootloader option is in red and I can't pick it. I just read an article about how one plus reallly likes this kind of thing and that is what inspired me to start flashing away, but I have had no luck.
Is your phone carrier model with carrier specific rom inside of it? Could that be the reason? Anyway, enable USB Debugging from developer options and try oem unlock from fastboot. Keep in mind that it will wipe your phone completely so backup everything you don't want to be lost forever.
Also you might void your warranty.
Hello, as you all can see I have the T-Mobile version of this phone. I have tried everything and I cant get the device rooted. I bought this phone unlocked from Amazon and I use it on Mint Mobile. I have no idea how or even if it effects the rooting process but, I cant think of any reason why none of the methods I've used dont work. I have tried using the "All In One Tool" and the same thing happens with that tool, that happens with every method I've tried; I can use a cmd window to boot into fastboot but, once I am there none of the commands I enter seem to have any effect. I can explain more but, has anyone experienced this or knows what the problem is?

Hi. So I wanted to put together a little write-up on how to root the T-Mobile McLaren 5G variant, at least how I rooted mine, as there doesn't seem to be anything about this yet. I was actually able to root my device last night successfully, so I...

Assuming your phone has been SIM/carrier unlocked by T-Mobile, you then need to request an unlock token from OnePlus. All info in above thread
But I highly highly highly recommend making a backup of your persist partition using the MSM tool before even unlocking the bootloader
