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.

Considering this is a tablet, hopefully I won't lose or misplace it
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.

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.

The unlocked bootloader warning message can easily be removed too: http://www.droidviews.com/remove-bootloader-unlocked-warning-on-moto-x-and-moto-x-2014/ I tested it and it work on our Moto X Play.
Oops.....completely forgot that this will wipe the phone (as all devices do when unlocking the bootloader).

They already know since you requested the bootloader unlock code. From the terms and conditions:
THE FOLLOWING APPLIES TO ALL UNLOCKED DEVICES EXCEPT FOR DEVELOPER EDITION DEVICES. BY OBTAINING THE UNLOCK CODE FOR THIS DEVICE, IRRESPECTIVE OF WHETHER THE DEVICE'S BOOTLOADER IS SUBSEQUENTLY UNLOCKED OR ITS SOFTWARE OR OPERATING SYSTEM IS MODIFIED, USER AGREES TO WAIVE AND VOID ALL WARRANTIES

Failed to unlock Bootloader. Check "Allow OEM unlock" in Developer Options.
Anyone please help me.
I tried to install the official OTA and something went wrong. The device got stuck into bootloops. I entered into bootloader and decided to unlock it. As adviced by the xda thread i followed the instructions, but after getting the Unique key via Email, when i enter "fastboot unlock OEM UNLOCKKEY", it gives an error saying Failed to unlock Bootloader. Check "Allow OEM unlock" in Developer Options.
I cannot boot my phone.

There is a thread I created for the first timers.
You have to check the option "allow oem unlock" in developer options.
Please check the whole forum for details before doing anything like this.

If you leave it unlocked after rooting then it can make your phone more susceptible to localised threats like someone stealing your phone and re-purposing it or stealing your data from it directly.
But for many the reward outweighs the risks and there are ways to mitigate.
Trying to unlock Moto X Play on Linux by using "fastboot oem get_unlock_data", but it just says waiting for device. I ran "adb devices" and also enable "Allow unlocking device" in the Developer menu. Am I missing something?
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.

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.

Why would you want to relock it? But if you wish to do so, you'll need to firstly enable developer options, once done go to settings then developer options, then you will see oem unlock, if that switch is to the right then boot loader is unlocked, to relock bootloader just press and move so that switch is to th3 left

You're mixing up two different things, oem unlock that unlocks the bootloader is disabled on the g950f, you have to enabled it yourself. The unlock code is for carrier locks, totally different thing. You might as well root it now and use magisk to hide root from netflix.

That's the thing, I wasn't rooted but I had unlocked bootloader and it wasn't working.
Now that I've rooted it using Magisk, the device is "certified"
I'm quite interested in buying this device (Nova 3i), but it's very important to me that i can root it.
I've noticed that the option "OEM Unlock" is not greyed out, and can be easily enabled, at least in the devices that are sold in my country.
So the question is:
Is it enought to enable "OEM Unlock" in "Developer Options" from the phone settings to unlock the bootloader and I can simply install TWRP afterthat?
Or do I still have to unlock it using unlock key from Huawei Website (which is unavailable)?
And if not, is there any other way to root it? Has anyone had luck in rooting it (e.g. Kingroot, etc)?
Thanks in advance.
