This sounds really sketchy so I'm not going to try it without confirmation that it works. Since G900A and G900T are basically the same device, one with a locked-down bootloader and one with an unlocked bootloader, shouldn't one be able to flash the unlocked bootloader and bypass the signature verification on recovery and system? Wouldn't this make the G900A usable and unlocked from the stupid locked bootloader?
Is there any way to investigate if this works without the possibility of hard-bricking the device?

lol, okay, I won't but is there any way for us to determine whether it would in fact work based on the binary? Is my theory sound?

i dont know but flashing a bootloader for a device it was not meant for is a great way to hard brick. why not just stick to safestrap?

Safestrap does not IIRC allow me to encrypt my userdata partition. As a privacy and security-consious person, that's a hard sell for me.

my friend said that the OTA updates require locked bootloader, then I would like to lock it again ...
and how this under warranty, also wanted to make everything from factory
Your friend is wrong. You don't need locked bootloader to get OTA.
To get OTA update, you need stock rom and stock recovery, locked or unlocked doesn't matter.
You can also flash the factory stock image without wiping your data (see link in my signature).
If you have root you can use this app to lock and unlock your bootloader: https://play.google.com/store/apps/details?id=net.segv11.bootunlocker

I guess something is up with your phone physical memory, but it doesn't matter, it really should not affect your warrenty (but the custom rom and recoveries will). Makes zero different to OTA updates either.

Honestly, I don't think they care if you have root either, but that's base on other user feedbacks. It seems LG warrenty is picky about other things and not very good from the feedbacks from what I read actually, but I haven't had first hand experience. But people have sent in rooted devices for repair.
I think just have factory image and stock recovery and stock kernel.
Solution !

What, precisely, must be done to unlock the bootloader for an SM-G900A or SM-G900T? Must something cryptographically be broken? If I get root access through towelroot, will that help? Are the people at the AT&T store capable of doing this bootloader unlock if pursuaded to do so?
No they will definitely not help you unlock the bootloader lol. AT&T locked it down themselves, and no one has found a way to unlock it yet. All we can do is wait for someone to figure it out.

Can you show what is your Bootloader version?
Just an FYI, 900A is ATT with locked bootloader, the 900T is T-mobile which already has an unlocked bootloader. Just buy a 900T unlock the Sim and put in an ATT Sim. That's what I did. No worries about locked bootloader!

I think a read something about Safestrap being able to unlock S5 locked bootloaders, here for example. Not sure if this works though, have not tested it myself.
How can we know if the bootloader is locked or not? Is there a way to know it through adb or through a secret code?

It's only "locked" on 900V and 900A (Verizon and AT&T) variants. Other variants are not locked nor lockable.

I thought I was clear, sorry.
If you have the Verizon or AT&T version, it is always locked. If other version, it is always unlocked.
There are no known ways of locking or unlocking the bootloader on a Samsung device.

Thanks again. I already know that besides Verizon and AT&T, all the versions have the bootloader unlocked, but is there a way to know that through adb or a secret code? i.e. If Knox is 0x1 we realise that the device has been rooted, likewise, is there a way to know if the bootloader is locked?

i have its gotten me nothing so far
in retrospect
I just got my hands on one of these and I'm not sure if the bootloader is locked or not I did a procedure that leads me to believe it is. I am not 100% sure though, and since I am not really a noob, nor of a minor tech, I understand the importance of being 100% certain.
What is the model of the phone according to the phone's screen in download mode? What is the boot loader version?
These two items will help you determine whether the boot loader is locked.
All Canadian Note 3

Does this "Unlocked bootloader" apply to all Canada versions of the SG Note 3 N900W8 as well? Thanks in advance.
I have a major problem, I need to know if it will be possible to flash a custom rom on a nexus 6p. It seems that it will be hard because of that new bootloader.

The bootloader does get updated. But you can unlock any bootloader, and updating it doesn't lock it again. Take a look at my guide:

Oh, because i was afraid of the phone won't boot because of the android n won't boot if the phone has a unlocked bootloader.

Nope, nothing like that to worry about. The locked/unlocked status won't stop it from booting.
Thanks. I can now upgrade in peace
I dont want to unlock bootloader yet. So i wanted to root the device safely without flashing anything.
You simply can't flash any zips unless on a custom recovery and for that you have to unlock bootloader.
BTW the first thing i did upon getting my op5 was to unlock the bootloader.
"Root without flashing anything."

You're more likely to brick your phone using a janky and sketchy no-unlocking method than using the documented and manufacturer-recommended method.

Rooting touches your device just as much. Unlocking the bootloader is like using the key to open a door to get into a building. Trying to do it without unlocking is like using a sledgehammer to break in through the door.

You can just lock the bootloader again and noone would know you'd unlocked it. One Plus isn't like Samsung!

Yes but one-click root apps are very unreliable in general and most don`t even work nowadays (especialy system less root). Unlocking the bootloader and flashing Magisk or superSU with TWRP is the best and safest method atm.

Sorry, quoted the wrong user meant the post of @xabierd
Mate, if you don't want to replace your recovery with TWRP, go to fastboot, make sure you have your phone discoverable and use the command "fastboot boot recovery.zip" - recovery.zip being TWRP. This will just boot into TWRP where you can flash magisk or supersu. This won't replace your stock recovery.
You will still need to unlock your bootloader however...
