I was wondering,
what does the bootloader display when you relock it using the fast boot lock command.
Does it say relocked or locked?
Thanks,

It just says locked, just done it with mine
So does that mean that you can restore to complete factory settings and get warranty back?

Yeah, returned mine a few days ago to Tesco UK.
I used Wug's rooting toolkit, but it's your choice what you use. It downloads and flashes the stock image for you, so there is no evidence of root.
Then you use to Lock OEM feature, to re lock the boot loader. They will never know that you unlocked it

I've searched and couldnt find info on this. I need to RMA my phone due to dead pixels and I want to ensure there's no issue with warranty.
How can I unroot and re-lock the bootloader?
Thanks in advance.
Flash the stock image. Check efrants sticky.
After its flashed type the command: fastboot oem lock

I'll try it tonight, thanks for the response.
The toolkits available in development have options in them to reverse everything. I used mskips toolkit to unlock mine and root it, takes all the guess work out of it.

i am about to buy a used nexus 4 which is unlocked. I would like to ask if when locking it back (in case of rma) it says locked in the bootloader or it follows HTC policy showing "relocked". Thanx in advance.

It says "LOCKED". I checked it just now.
I am new to the Nexus 7 and have a small question on the boot loader unlock.
If i unlock and re-lock the bootloader on the N7, does the N7 go to a 'Re-locked' state or just goes back to 'Locked' ?
I come from a HTC one x which goes to Re-Locked

Ah thanks for the clarification
Is it possible to re-lock and unlocked bootloader?
I know updating should get rid of an unlocked bootloader, but I still get the warning screen on bootup.
Reason I ask is because I had it unlocked, got an OTA update from Verizon for kitkat, and soft bricked my phone. Got stuck in a boot loop with the unlocked bootloader warning message.
I just flashed back to 4.0.4 using RDS Lite 6.1.4. Id like to reset the boot loader to locked before updating to kitkat again.
It's not possible to re-lock. I've updated to KK and can confirm that the BL is, in fact, still unlocked.
I have read somewhere that when you unlock the bootloader, it actually physically blows some kind of physical fuse. or maybe I miusread it.
Someone had made a special logo.img you can flash to get rid of that message.
Although if you really want a locked BL phone, I'd be more than happy to trade you.

Not that it helps, but in Australia, we do not get the nasty warning message after unlocking the bootloader. And I think that the phones are actually sold with an unlocked bootloader.

The new Device Protection features of Android 5.1 on the Nexus 9 and Nexus 6 can, in certain cases, cause you to have a bootloader which can not be unlocked.

i would never relock my bootloader
people unlock there bootloader for a reason
but to relock it after thats just wrong...
thats one of the things i hate about CM
they recommend you to relock your bootloader...
Agreed, why would you lock your bootloader unless sending in for repairs maybe?
But Google is really messing up the flow. The nexus 6 5.1 OTA is a mess right now but I will leave that for another thread.
Android 5.1 for Nexus 9? You must be joking.
So, I just purchased a Nexus 9 via the 4-hour online-only sale at Best Buy. It was $100 off, couldn't pass it up. My question is: is this likely going to be shipped in such a condition as to prevent me from permanently unlocking the bootloader? Or is a permanent lock something one must deliberately do?

No no you can still unlock it
But if you relock it that's the problem

As USBhost said, you'll be able to unlock it. However, when you are first setting it up and are running through the set-up wizard, there will be an option to "Protect Device" or something like that. If you enable it, and re-lock the bootloader, it will put you in a situation where you can only unlock the booloader in certain situations -- and if you happen to have a bootloop with a locked bootloader, that's when you are in trouble.
EDIT: On Nexus devices, I personally unlock the bootloader as soon as I take it out of the box, without first booting into Android, and then leave it unlocked. But of course, you give up some security by doing that.

Thanks, guys! Glad I stumbled across this thread before the thing arrived.
Locking the bootloader doesn't protect you from anything. If the device leaves your physical control in a potentially hostile environment, whatever is on the system or boot partition becomes suspect, regardless of whether the bootloader is locked or unlocked.

Example: I have a device running a stock ROM with no encryption, the stock recovery and a lock screen password. I happen to lose my phone. What happens to the photos of me dancing to Old Time Rock & Roll in my underwear that are stored on the device? If the bootloader is unlocked, someone just plugs it into a PC, boots TWRP and pulls them off. If the bootloader is locked, there is no easy way to see or get the photos off the device.
That is all I was saying about security. Nothing to do with you leaving your device somewhere or losing it, and then finding it again. Strictly about the personal content on the device.

I thought Lollipop always requires you to go in and check the Enable OEM Unlock box? Or is that not true if you never booted into Android even once?

If you have never booted into Android, then you don't need to check that setting. As I said, that's the way I did it on my N6: take out of box -> charge -> boot directly into bootloader -> "fastboot oem unlock". No other steps required if you don't boot into Android first.

Yes, that should work for the N9 as well.
The bootloader on my Nexus 9 Android 5.1.1 is locked forever due to my mistake
Short backstory:
- I wanted to install the Android M developer Preview for the Nexus 9 but I forgot to check "Enable OEM unlock" in developer options (worst mistake).
- I used adb command to flash the new image but failed somehow
- I carelessly type # fastboot oem lock
- I tried to factory reset from bootloader to bring it back to Stock. Now it couldn't factory reset and my Nexus 9 hangs in a nice boot loop.
- I try # fastboot oem unlock but failed with permission denied error
I tried some ways to save my device but no hopes
- I used Nexus Root Tookit to unlock bootloader or restore image with force mode but failed,
- I follow instruction in HTC dev forum to get identifier token in order to receive your unlock code binary file but failed
- Unluckily, I don't installed any custom recovery.
Please help if you know a way unlock the bootloader or flash the factory ROM to save the nexus 9

Not possible. You will have to return it to HTC for repair or replacement.

Yes, I forgot to check the box to allow oem UNLOCK. And now my device is locked forever.
A quick question: A lot of N9 ROMs require flashing an updated bootloader from the factory image. Aren't these bootloaders locked by default? Can we flash a factory bootloader over a custom ROM?
It seems that we might bork our Nexus 9s if we flash a locked bootloader in.
Hi Guys
I have 3 questions regarding Moto X Style Bootloader unlocking.
Can we unlock the Moto X Style bootloader after locking it after first unlock?
Can this process be repeated multiple times if we need to?
Can we use the same unique unlock key that we received while unlocking the bootloader for the first time?
Thank you
Why would you want to do this?

Yes you can do it as many times as you want but 1: Why would you relock afterwards 2: You will have to deal with a factory reset every time

Theres no reason really to relock it. Once its unlocked, the bootloader will show that it was unlocked regardless if you relock it.

Thanks for your reply.
The reason for attempting to re-lock bootloader is to get the OTA update from Motorola till date, especially Reliance Jio VoLTE support...But if I wish to make any further changes to my phone with any custom rom I should be able to do it by unlocking the bootloader again.

You don't have to lock the bootloader to take an OTA. You just need to be in a completely unmodified stock state: stock recovery, unmodified system, no root, etc. Bootloader can be unlocked.

That might work. Frankly I'm not sure. I haven't actually taken successfully an OTA on any phone since sometime in 2013 honestly.
I once flashed this phone totally back to stock. Every partition but logo, and it failed to take an OTA. I don't know if it failed because I had a modified logo, or maybe I had mounted system r/w. Not sure.
Hopefully someone more knowledgeable on this topic will chime in.

The answer is maybe... it depends what you have changed and what this OTA updater script actually checks for.
We know that a stock bootloader (which can be unlocked, that is not relevant), stock recovery, and stock system image are required to take an OTA. If the system image has been modified it can fail, and we know the updater has the ability to see if /system has EVER been mounted R/W and can fail for that condition although so far it doesn't seem Moto is going that extreme.
We do know a modified logo does not affect an OTA, in fact, you can even relock the bootloader with a modified logo so it must not be a significant check.

On my father's moto e lte I received OTA without issue with unlocked bootloader, I just flashed stock image and it was ready to update, btw I'm not sure but I've seen somewhere info that you can change bootlogo even with locked bootloader so I don't think that's the issue.
Btw after you once unlock bootloader you won't be able to truly lock it again, next time you will be able to unlock it without any code so you lose some security in this process, frp won't be working anymore.

You still need code to unlock each time, but it's the same code, and if you relock OEM Unlocking gets turned off and you would have to turn it on again... So if something fails on the first boot after relocking, your f*cked, no way to unlock.
And FRP definitely works if the bootloader is unlocked, it is just much easier to bypass.
