Yes it will lock bootloader only if you have verizon or AT&T N910V/N910A.
On Other models the bootloader will lock just to downgrade to 5.0/4.4.4 if you flash 6.0.1 bootloader.
You won't be able to downgrade.

I'm sorry but you contradicted yourself (makes no sense).
On other models bootloader will lock "just to downgrade to 5?" if you flash 6 bootloader? I don't understand.....

I mean once you upgrade to mashamallow bootloader you cannot downgrade to 5.0 or 4.4.4 because bootloader will lock just to prevent downgrading otherwise no issues with root/roms/recovery.
You can still downgrade to 5.1.1 though.
On at&t and verizon bootloaders are locked for downgrading and flashing recovery/rooting etc.

No only 5.1.1
If you try to flash 5.0/4.4.4 it will fail in odin

You've been great help regardless, no problem! It's not that bad
Also - I have a Note 4 from Verizon - is that bootloader unlockable now? I do however have that on 6.0.1 already I think so no?

You can downgrade to 5.1.1 by odin then you can unlock bootloader .
on marshmallow is not possible so far.
You can watch video in link below step by step tutorial by zedomax
It's still pain in the butt though to unlock but if you got patiance then you can do it.

Link below there is a guide first you have do downgrade to 5.1.1 then upgrade to marshmallow without relock the bootloader.
Once you do that then you can flash any marshmallow rom.
Good luck.

Even being able to read chinese, understanding is still difficult. . .It says one must at least have a leaked 4.3 installed, is that right? Then I guess this is only for unlocked bootloader user

yeah, very difficult to understand, i think first unlock BL then flash kernel with CWM, flash supperuser, and then flash stock 4.3 kernel to relock BL
i am chinese
this root method is only for unlocked boot loader
flash the leaked kernel
that relock

[Q] Can you be rooted and have a locked bootloader

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...

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 ?

[Q] Update N910T with stock firmware w/o updating bootloader?

I have an SM-N910T running N910TUVU1COG2. I've kept it at this because I didn't what to lose the unlocked bootloader.
Is it possible to update my N910T with stock firmware without updating the bootloader? I've done it on other Android phones without any problems, but am clueless about the Note 4's ability to do so. What say you all?

Well, that totally sucks. Damn Samsung/T-Mobile. One of the main reasons I bought the phone was because it had an unlocked bootloader so that I could do as I will with it. It was bought out-right, unsubsidized, and I should be able to install what I want without worrying about the bootloader getting locked. So I guess I'm stuck at COG2 for a while longer, at least until my desire to keep the bootloader unlocked is overcome by my desire for new hotness.

If once you upgraded to marshmallow you can only downgrade to 5.1.1 OK1 but no 5.0 or 4.4.4.
But with 5.1.1 OK1 bootloader you can still flash 4.4.4 and 5.0 roms with custom kernels and they work flawless.

Only revert lock. But if you are looking at rooting, recovery and flashing roms its not locked. I took mine to PE3 MM and left it there.....
OK, I'm confused.
Sorry to belabor the point, but I'm confused. If the bootloader is unlocked, then should I not be able to flash any ROM, Samsung's or not? i.e. I don't understand how the OK1 bootloader, if it's unlocked, will prevent me from flashing COD2. Or is it that the bootloader itself will not properly boot anything prior to OK1?

How to Downgrade?

I'm currently on android pie version PPSS29.55.24-2 and I'm experiencing severe lags on this version even after factory resetting it several times plus the audio quality is ****.
Bootloader is locked, can someone provide an step by step guide to downgrade it to Oreo?
Any help would be appreciated.

There is only one way to downgrade firmware. You need to unlock the bootloader. If you cannot or do not want to I can't think of another way. Sorry.
