I'm interested in rooting my nexus 6. I know that you have to unlock the bootloader in order to root the phone and install a custom recovery. But after all of that is done is it ok for me to re-lock the bootloader for security reasons or will it have any issues?
Thanks in advance.

Why is that the case? I was able to unlock flash 5.0, relock and side load 5.1. Did Google change something in 5.1?

Yes. Very much so.
problem is.. you now have to enable oem unlocking, to unlock the bootloader. technically, you can still be rooted and lock your bootloader. but the problem is that some have gone back and relocked their bootloader(not with root i dont think so) only to find that they cant boot up, that they end up with a boot loop. and then they cant unlock their bootloaders to flash the factory.img, because you need to check that setting first, to unlock the bootloader. honestly, i think someone with root, and twrp, would be able to. if not, you can fix it by formatting a few things(if you have twrp).

If you have a custom recovery installed, then having a locked bootloader is no more secure than having an unlocked one...

NOOO!!!!
To many folks have encountered an issue that soft-bricked their device afterwards.
You will still receive OTA with an unlocked bootloader.

you can relock it (safer) but if you want to flash any new rom later you will loose all your data. cause everytime you flash you need to unlock the bootloader. its up to you

Hang on now, lets be clear about the advice that we're giving here.
Yes, a locked bootloader is safer if a thief were to get his hands on your device. However, locking the bootloader has a whole host of other problems linked to it. For example, if you end up in a boot loop with a locked bootloader because something breaks in the rom or kernel, if you have stock recovery, you can never unlock the bootloader again, without sending it for repair.
I would suggest people using experimental ROMs should keep their bootloader unlcoked to avoid this

If I did lock the boot loader, can it not be unlocked again using NRT ? I'm wondering since this (Android M) is an official release from Google, there should be a way to unlock the Boot loader if someone wants to roll back to lollipop ... Am I wrong in this assumption ?

It's a security feature whereby if you do not have "enable OEM unlocking" set in the rom, you cannot unlock the bootloader. If you don't have it set, have stock recovery then have a rom that will not boot, you cannot set that, ergo cannot unlock the bootloader. If you're going to mess with exxperiemental previews, I would suggest not re-locking the bootloader.

I just checked and the 'OEM unlocking' option is turned on under Dev Options.
So, can I unlock the bootloader and flash back to 5.1.1 ?

Hello! I just got a nexus 6 a few days ago, and I love this phone! However, I just read on here that relocking your bootloader is a bad idea? Well, I rooted my device and installed PAC ROM on it, then reflashed a stock image back to my nexus and relocked the bootloader, my phone is fine, no bootloops and no issues, does this pose a problem with OTA updates? Thanks! I really need to know because i would NOT wanna brick this thing! Thanks!

Thing is, when your bootloader is unlocked, the device is almost unbrickable. Also, you can be unlocked, 100% stock and still get OTA's if you want. If you have a locked bootloader, mess something up and end up in a bootloop, and can't boot to android, you're stuck.
Are you saying that OTA updates work even if your boot loader is open? Does it just check your system files and recovery? In theory, if I did an OTA update right now, and my bootloader was unlocked, it would install without problems?

Yes to all your questions.
Unlock it, its free insurance and wont change or harm a thing.
you can lock/unlock your bootloader anytime you want actually, you just have to make sure that you relock your bootloader sfter making sure that you can boot properly first. because if you can't boot, and your bootloader is locked, then you are just as good as bricked. because now, to unlock your bootloader, you have to enable allow oem unlock. and if you cant boot, you cant do that.

That said, since 5.1.1, doesn't "allow oem unlock" remain ticked / selected after a reboot now? If so, it's fine to relock it, even if it doesn't boot if that is ticked.

Yes, but in the case of an "accidentally" wiped OS, well, you know.

Well it shouldn't matter. When you tick that box, it writes the change to mmcblk0p18, which is OS independent. Now that booting the rom doesn't revert that partition, if it is ticked once, it shouldn't matter if there is an OS at all.

Correct. Bootloader status has no effect on OTA. Updated script checks boot.img (kernel), system.img, and recovery. All have to be unmodified. No root, no unencrypted kernel, stock 100%.

Scripts don't check recovery. It's just the OTA zip won't work without it.

Real quick easy noob question, no point in making a thread just for this so I'm asking here, is the Nexus 6 CPU an arm or arm64?

N6 is ARM. Arm 64 is for 64 bit devices such as the N9.
Clarification question
A question for clarification, as long as the bootloader is already unlocked, the "OEM Unlocking - Allow the bootloader to be unlocked" setting under Developer options doesn't affect anything?

So I am the prime v6. 5 rom. I have twrp, I'm rooted and I have xposed. Would installing the 6.6 update brick the phone? I just don't have the bootloader unlocked. Any help is appreciated!
I thought you had to have an unlocked bootloader in order to install TWRP and root. Are you sure your bootloader is locked?

I got twrp and root without unlocking the bootloader.
I ended up doing that later by running rootjunky's script. It will wipe your data. So you would know if your bootloader was unlocked. If you look on his thread, he has a way for you to check.
Of course this all assumes you aren't on 6.6.

And why do you want to relock? Paranoid about security? Keep your phone in your pocket.
All advice in XDA is not to relock your bootloader because it reduces the possibilities of recovering if you ever make a mess of an update.

Just install a custom Kernel that "kind of" hide your unlocked bootloader. EX Kernel, Franco and some others will be just fine. Android Pay will work... I would never lock the bootloader of mine, except for RMA purpose. If something fails, you have way more chance fixing it..! :good:

Yeah don't worry, it's still a Nexus
RacerXO - did you get Android Pay to work on the N6F26U Build? I also cannot get the bootloader to relock. I tried using WugFresh Nexus Root Tookit v2.1.9.
Did you install a custom Kernal? Wondering if this the answer. Thanks for the help.
I was unlocked from the first day I got the phone. Today I am locked, running nougat. Having read some of the horror stories here, I've always booted the phone after flashing updates before rooting. Did the same thing when I went back to stock to use AP. I backed everything I wanted to keep and made sure it booted, before I locked the bootloader. No issues after almost a month.
What I wound up doing was go to the T-Mobile page and established the official latest factory image was 6.0.1 MMB29K - installed that using Wugfresh. After installing and logging into WiFi and my Gmail account was prompted to install 7.0.0 NBD92G - this installed fine and then after installing a couple of security updates (thru April 2017) was able to Re-Lock my Bootloader (I wanted Android Pay to accept my credit cards). Data reception is still degraded significantly, am now thinking there is a problem with the tower.

Rooting with Magisk then using Magisk manager to "hide" root should give you android pay again. This may not be the directing you want to go in, but it is an option.
I locked Bootloader but you have to flash stock recovery 1st
I was on stock 7.1.1 unlocked bootloader, rooted Nexus 6.
I relocked my bootloader by simply going into adb/fastboot and flashed the latest stock factory firmware image (not the ota) with the June 5, 2017 security update, rebooted, activated developer options and enabled usb debugging, adb/fastboot again, and entered the command "fastboot oem lock", hit okay/yes when I got the relock warning, and voila! phone relocked.
Rebooted and set up phone/reinstalled my apps, music, and files.
No issues.
Yeah the title says it all. Just wondering if that's possible or not since I'm not sure if I'd have to wait for a week for my phone to be unlocked, while I could get the job done in no time.
If unlocking the bootloader is required, then would force unlocking it using mtkclient work (triggers bootloop, haven't tried to relock it and see if it fixes it)? Or will it only work through official bootloader unlocking?
No, you need to unlock the bootloader in order to flash a recovery over the stock one

You need to unlock first, since locked bootloader will block any flash over system partitions
