There is, theorically. Sziraqui was talking about it in his unofficial bootloader unlocking method.
And Xniperf, there is a theory that ASUS tracks if device was unlocked by serial number, so, unless you haven't used an app from ASUS, relocking your bootloader won't help you to recover your warranty.

As I said, it's only possible in theory, no one hasn't dumped locked bootloaders yet

Uh, yes, and I found out by the worst way possible. Since everyone was saying that re-locking the bootloader was impossible, I had the great idea to go to fastboot and type in "fastboot oem lock".
What happened you ask? The bootloader was locked... I had some trouble unlocking it again.

Yes the right way is flashing stock ROM from adb and with this type that command "fastboot oem lock"

Hello all,
Just a quick rooting question. Is there any reason to unlock the bootloader when rooting? According to some stickies, we can root without unlocking and I was able to root my friend's Captivate without unlocking anything. I am assuming we're unlocking the bootloader since it makes the rooting process easier as a hack isn't required? Thanks!

It allows you to flash a custom recovery image to go ahead and flash a custom rom and radio

Hi Dave,
Thanks for the info, but why didn't I need to unlock my friend's Captivate? We were able to get Clockworkmod Recovery on it without unlocking anything. Thanks!

The TL;DR of that article is that,
Every phone has a bootloader. The Nexus series (and now Sony Ericcson after filing out a form on their website) has a unlockable bootloader without the usage of any exploits. Phones such as the Galaxy S series (Vibrant, Captivate, Epic 4G, etc) -- mainly Samsung phones have weak bootloader protection.
HOWEVER, all of the other phones' bootloaders are unlocked due to a exploit. So yes, your friend did unlock the bootloader without actually knowing it.
The only phones that are unable to unlock the bootloader are Motorola phones because of the bootloader being signed.
But if you really want to know about bootloaders, read that article.
@dave: there is no such thing as a custom radio. The radio itself is not open sourced. But it allows you to flash a older version of the radio since results of radios vary between user. Some people may experience better connection with KB3 than KD1 and etc.
Thanks! It was as I thought.

Correct. Most other phones require an exploit to root, the Nexus S does not - if you unlock the bootloader. Conversely, you might still be able to root the Nexus using an exploit, even if you want to keep the bootloader locked.

It's kind of a PITA to flash an updated Clockworkmod Recovery. That's all I've found out.

^ but to be honest, not to many things get changed within the recovery. Sure the modified Clockwork recovery gets updated. But the original clockwork from ROM Manager doesn't.. it'll work, but I don't see a reason on keeping the bootloader locked. No security is ever compromised.

Funny, I actually paraphrased the OP. He was on the right track anyway, just needed some confirmation, not a whole paper Also there's a lot of stuff in there I don't really agree with all that much.

Flash (and probably boot) stuff via fastboot.
Have installed the 4.2 update via recovery and locked the bootloader. Will I now get future OTA updates from google?

The bootloader being locked or unlocked makes no difference. We typically see people OTA update fails from people who have modified system apps/files or installed a different kernel.
Ah ok. I had previously rooted it. But decided to revert back now that I have installed 4.2

Unlocking Bootloader
So, can you unlock the bootloader on 4.2? Or does it even matter on what Android version you are on?
Thanks and Cheers!

Yeah, but is the method for unlocking it on 4.2 different from the method on 4.1.1?
Sorry Im asking all these questions, rooting is a bit different from jailbreaking lol

Haha, no. The method is still the same. And I suspect it will be the same for a while to come.
Oh and welcome to the Android world
The bootloader is unrelated to the version of Android you are running.
It is a " boot loader" that runs before the operating system is loaded.
Unlock it once, when you first get the device - and it should stay unlocked forever.
Nothing to do with root either - except the bootloader has to be unlocked to root the device.
Root and unroot the device as you like - just never mess with the bootloader after you unlock it.
Unlocking purges all your files...

fastboot oem unlock
It hasn't changed since the first Nexus device and won't be changing any time soon.
Welcome to an open platform
Before I get this phone. Does anyone on AT&T know if they white-listed this device for VoLTE?
Also, can we re-lock the bootloader like Nexus Devices or once the bootloader is unlocked it can never be re-locked again?
Thanks

You can relock the bootloader if you want to unroot and return to stock.

Thanks I posted the question there..as I did not get a definitive answer. When I say relock, i want the behavior like the Nexus phones where it will do another wipe after the fastboot lock and fastboot mode shows correct lock status. Used to have one plus 1 and once unlocked you could never relock the bootloader..

AT&T only supports VoLTE on AT&T branded phones. So unfortunately, no.

par for the course w/ that company. I think they have taken the mantle from Verizon as being the biggest jerks. If it wasn't for their iPhone business, they'd be sunk. They have done a fabulous job of raising the prices of all things DirecTV too. ugh.
I just flashed latest Nougat and wiped my device. I am trying to find out how to re-lock BL. It seems that Fastboot oem lock doesn't work. Anyone know the function to use?

I am trying to sell it. If I leave bootloader unlocked, it may deter buyers. Are you saying relocking bootloader when it's 100% stock doesn't work? Why?

If you are truly 100% stock... Then sure... Lock away...
I'm not going to spell it out... For fear of the stupid...
But substitute 'flashing' for 'oem'...

If you just flashed Oreo, then it is beta.
Typically you don't lock the boot loader with beta software running.
If something goes wrong, and it can, you potentially won't be able to flash a downgrade.
I understand your reasoning, but it's normally a bad idea.
Although, essential doesn't instruct you to unlock the bootloader to install the Oreo beta builds.
I side loaded mine through the stock recovery and only unlocked a few weeks afterwards.

It's all good. I restored to Nougat before I re-locked. :good:

That's the SPerry xt1766? You can unlock the bootloader. I might be wrong, but you should be able to do it right thru the Motorola website:
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-b
Of course.... you lose all your data when you unlock your bootloader, so back it up

Right.
You have to do what it says to do. Enable Oem Unlock in Developer Options.
To make Developer Options appear, go to Settings... About Phone... and tap on the Build Number repeatedly (7 times) until Developer Options appears, and enable it.
Then go to that Developer Options, and you'll see the 5th one down is OEM Unlocking. Enable it.
Ta da.
Now go and do the fastboot oem unlock thing.
Thanks a lot Man.
Thanks a lot man, would you please be specific about the “oem unlock thing”?
