[Q] How to unlock the bootloader?

I'm getting my T-MO G3 returned soon and would like to unlock the bootloader asap but I'm not exactly sure how. Is it just FASTBOOT OEM UNLOCK or is there something else?
Boot loader is not locked

Whenever I've unlocked a bootloader, it wipes the device. I'd rather do that before I set it up with my apps and accounts.

Correct me if I am wrong but every phone comes with a locked bootloader even the nexus line you need to unlock. We really need to stop calling encrypted bootloaders locked. So this phone isn't encrypted but surely it is locked.
Our G3 is the only one that's unlocked.

Guys. There is a difference between unlocked and unlockable. This being unlocked means there's nothing really to do. That's why it's so unusual.

relock verizon bootloader

OK so I am going to have to return my pixel xl for a factory refurbished due to hardware issues with the camera flash. How do I relock the bootloader before taking it back?

You better be absolutely sure that your device is completely stock before relocking the bootloader. Once you are sure, boot into the bootloader and type, fastboot OEM lock

@shibbnasty. Actually, relocking the bootloader may not wipe data. I can't remember. Let me know if it does or not.
Yes it does.
Rank N00b here... just getting that out of the way.
Device: Verizon Pixel XL
Build: NDE63X
Bootloader: unlocked via dePixel8 (done after Nov update)
So the phone is stock and I'm not really keen on modding right now. I don't want to use a alpha build of TWRP and SuperSU seems to be in flux too. These aren't criticisms by the way; I realize this a very new handset and those kinds of tools take time to develop. Nothing happens overnight.
So, anyway, my phone is currently unlocked and I'm wondering if I'm not better off relocking it? As a stock unit, it should still get OTA's, right? Like I said, total n00b here...
@loaba,
There's absolutely no reason to relock your bootloader, unless you are annoyed by the Google bootloader unlock warning during boot, or if you are planning on returning it or selling it. Otherwise, leave it unlocked. Gives you much greater flexibility to recover if something goes wrong.
@cam30era,
Thanks for the reassurance.

Also, Verizon may remove unlock ability via dePixel8 in their December update.
If that happens, you might have to wait awhile to get Unlock on a VZN Pixel again.

So if I want to maintain an unlocked device I need to act now... Guess I'll see which comes first - the possibly debilitating Dec update or a stable TWRP build (and a correspondingly stable custom ROM).

Yep, do nothing and stay unlocked. You will still receive VZN OTA's and stay up to date as long as you do not install a custom recovery or kernel.
AND since you've remained unlocked, when the time comes that you do want a custom kernel or recovery, you can get them.
If it gets messed up somehow, you can do a clean RUU install as if nothing happened. If it's locked, you can't do that as easily.

You should do some reading. It doesn't work like that. If you ever lock your bootloader you will never be able to unlock it again. No reason to lock it anyways.

I don't think you are correct. If you leave the bootloader on 7.1, you should be able to unlock it again using depixel8.
Where has anyone done what I am proposing to do - upgrade everything but the bootloader to 7.1.1 and leave the bootloader on 7.1? No one has done it. So no one knows.
im pretty sure you have to manually relock the bootloader,so updating to 7.1.1 shouldn't matter.
They cant relock your bootloader through software is what i was told by depilxel 8 developer.
I am updating to 7.1.1 right now just to get back to factory state need google support.
cant be reached on most custom roms.
No current stock rooted roms exist,so fresh start is needed.

As soon as you update to 7.1.1 and you are locked, you will not be able to unlock again with depixel8. I don't care if you have a bootloader from 2 years ago. You probably should decide once and for all if you want the device secure and locked or unlocked. Otherwise at some point you will be in a pickle.
Sent from my Pixel using XDA-Developers Legacy app
There's always a way to find out. Let us know how it goes.
You should not be locking you're bootloader if it's not necessary. And depixel8 pushes stuff to system in order to enable allow oem unlocking. These things may not work on newer systems regardless of the bootloader version.

Your OP implies you can update everything else except the bootloader leaving you free to lock and unlock whenever you want which is 100% not true. There are new threads about this every week all the info is there. If you are on 7.1 you can unlock with dePixel8. Yea technically you could relock and unlock again ONLY while on 7.1 but there is 0 reason to. If you aren't 100% stock when locking you are going to have issues. Also if you're phone installs an OTA while you have the bootloader locked then you are 100% screwed and won't be able to unlock again. Either unlock it and never lock it again or don't bother. You're making something very simple overly complicated.

You can't.. it doesn't work like that. Go ahead and try if you want. There are countless threads about the bootloader. With all the knowledgeable​ people here do you think they somehow just overlooked something so simple? There are 5 bootloaders total actually. Once you install 7.1.1 you will not be able to unlock again. Multiple people have told you this but you seem to not believe anyone so go ahead and prove us wrong.

There is more than one bootloader which is what you are not understanding. There are 5. No one is certain exactly what 7.1.1 changed but if you flash any part of it (not just the bootloader) then you won't be able to unlock again.

Just wipe it and ship it. Google will only inspect it for physical abuse and water damage. The don't care if it's unlocked. It Google, the sell us unlocked phones. I too have sent them back unlocked as have many others.

Go to Google's factory image page download January's image and do the flash all to slot a. Then change to slot B.
Fastboot --set-active=b then flash all to slot B. Probably Overkill but you'll for sure be stock. Then issue you're relock command to both critical and the regular bootloader one. For one you need to make sure your fastboot is current if it's not up to date you're probably going to have problems.
Edit. I would just send it back the way it is

Pixel 2 XL no operating system fix

So I recently got my hand on a pixel 2 xl without the operating system.
I know this is an issue happened to some devices and the best way is to send it back to Google for a replacement.
However neither do I have the box and receive with me nor I am living in the official launch area. So there is no easy way for a replacement from Google. (I can't even post question at there official pixel user forum)
Therefore I really would love to know if I can indeed install the official ROM with tool like this one? https://forum.xda-developers.com/pixel-2-xl/development/tool-tool-one-driversunlocktwrpfactory-t3730226
And hopefully won't wasted a good device.

Did you have OEM Unlocking checked in Developer options before it happened? If yes you can flash factory images
If you have the stock recovery and can boot into it you can adb sideload the most recent ota zip.

You can get the bootloader lock status simply by booting into the bootloader. Locked or unlocked? You don't "think" it has a working recovery is not good enough to help you. If it does have a stable recovery, you can flash the OTA. If it does not and the bootloader is locked you are S.O.L. and the phone is dead. Follow this video and let us know.

If you can hold down volume and hit power to get into bootloader and choose Recovery, you can fix this phone.
Go here: read instructions at top. You will be booting to bootloader, then to recovery, then choose Apply Update from ADB.
Then give adb OTA command as described. Don't skip or modify any step.

If your bootloader is locked with no way to unlock it, and with no working recovery, you're screwed. The device needs to be sent to Google to fix, which is rather problematic when the device is in a country where it wasn't sold.
