Usually in unlocked phones, bootloader can be unlocked using "fastboot oem unlock" command from platform tools. Android 5.1 in android one devices has a new security option in that, the above command works only when "Allow OEM unlocking" is enabled in developer tools. It's an added protection feature in case you lose your phone, the thief may unlock the phone and flash a new rom bypassing your pin/pattern lock.

Yep same for me.I tried to unlock with this allow OEM unlock off and it unlocked without problem, so I guess it doesn't work for our phones.

Do you have Secured lock screen (PIN, pattern, or password)?
It's useless if you don't have any of these setup.

I have a password setup on my phone.

I have a Micromax Canvas a1 and when I try to enable this option ..... Then a warning message appears saying that "Device Protection features will not work while this feature is turned on" Then there are two option buttons "Cancel" and "Enable" When I press enable it turns on for a second and turns of itself

any way to allow this option via fastboot..?

help.

is it possible to unlock the bootloader without enabling developer options.
Well i think that is not possible.
You need to have android debugging enabled for unlocking the bootloader.
I tried doing it from cmd prompt,
It says
"remote em unlock is not allowed "
oem

I want to change the rom. I don't have access to the settings because I did a hard reset before enabling the developer options.
No worries I got the steps from rootjunky. He's done a good job.

boot load problem

Good morning? Still no effect. I wanted to solve it myself, but it was not. Includes fast boot mode. But the process is too difficult. It is too difficult to remove due to an unknown error during the update. My situation is terrible.
OEM unlock is not allowed and the boot loader is locked. OEM locks were not allowed, so they waited more than 10 hours in this state and failed. An attempt was made to unlock the boot loader, but failed because the OEM lock was not allowed. Before using Robin ..... I keep failing. I'm sorry I can not speak English. I tried to talk to Nextbit Forum but it failed. But still would like to use the next bit robin ....... OEM locks are not allowed and they are broken forever? ... I can not flash an image and I can not unlock it.
Can you boot into Nextbit OS?

Go to about phone in settings and tap on the build number a bunch of times.
Go back to the main settings page and click on the new 'developer options' menu.
Enable OEM Unlocking in that menu, and then go into the bootloader and fastboot oem unlock.

OEM Unlock = Unlock Bootloader?

If I understand correctly OEM unlock means that it unlocks bootloader, right?
So I have the OEM unlock option in my Developer Options and I'm wondering why people are using adb to unlock the bootloader instead of just ticking OEM option?
Is it not the same?
Can I just tick the option and flash twrp, rom, etc.?

Hi, OEM unlock option in settings is just a switch that enables/disables the unlocking of the bootloader. You must first enable OEM unlock in settings and then proceed with the actual unlocking of the bootloader
Google puts a number of steps so you can't accidentally unlock your bootloader.
Enable developer mode
Enable OEM unlock
Unlock bootloader (using fastboot)

SM-J260T1 Oem Unlocking isn't visible in Developer Options

I can't see the Oem unlocking option in developer options, is there a way to enable it that works? I have unlocked my device and recently reset it.

NEVER lock a phone with custom firmware installed. This usually leads to bootloops.

What are the steps you took before relocking the bootloader?
In my experience, relocking the bootloader should be the last thing you do, after you've got a working/bootable stock ROM.

So, after i installed the latest stock rom, the device worked normally, but after waiting a while for the oem lock option appear in development options, it din´t show up. so i just gave up and installed lineage 19.1 but if i can i want to lock the bootloader again.
Raphael, I think you might have quoted my post twice, but didn't add an actual answer. Or maybe I'm super blind and I can't see it.

So, the OEM lock/unlock thing comes with a pretty big caveat, and you need to be aware of it: loss of data.
Every time you lock or unlock your bootloader, a wipe data is triggered.
Now, for as far as I know, to lock the bootloader, you need two things:
1. Stock ROM. Don't do this on a custom ROM!
2. following command, in Terminal/Cmd Prompt
fastboot oem lock
Of course, you need to be in fastboot mode, so if you're not, and if you're booted and connected via USB (USB debugging needs to be ON and RSA fingerprinting accepted), do:
adb devices
It should display your device here. This is just to make sure ADB is working properly.
adb reboot bootloader
At this point, the phone should reboot into bootloader, so now you can do the lock command
fastboot oem lock
Data should be erased and, in case it doesn't automatically boot up, you can reboot the phone.
Don't worry about the OEM unlocking option in Developer Options. You just make sure the stock ROM is functional before attempting to relock the bootloader.

I tried that, and it din´t work, this method is the same that was in a help thread in xda forum of my device, this command works fine in my nexus 6, but on my moto one action it does not, i unlocked my bootloader via the normal method using motorola´s website, not using another method.

no, i run the command and it asks for changing the oem lock setting in developer options, i reboot the phone and run through the setup process. Then when i enable developer options and check the oem lock option, it is greyed out.
Is it greyed out in the on or off position? Can you attach a screenshot? I don't remember the operations sequence... But I think the option was automatically switched back to the original position (off) when you lock the bootloader. I could be wrong though. So...when you run the "fastboot oem lock" command, it asks you to....what?
Set the option to on or off? Some screenshots from both the PC, with the message, and the developer options might help to clarify this.

A screenshot would be really useful. But don't worry about it. When you're back to stock rom and ready to lock your bootloader, we can resume this then. I think either we're missing something, or it's everything ok, and you just need to switch that option off. Though, I remember I didn't have to do it manually. But I could be wrong though.
So, don't worry. Enjoy LineageOS and we can resume this when you're back to stock ROM and ready to lock.

so after running the fastboot oem lock command, it asked this in the cmd
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem lock
...
(bootloader) Check 'Allow OEM Unlock' in Android Settings > Developer
(bootloader) Options
OKAY [ 0.080s]
finished. total time: 0.080s
when i rebooted the phone, it showed the screen saying that the bootloader was unlocked. also i had to re run the command because it was going to erase my phone but that din´t happend, after going to developer options the option was still greyed out.
The last 3 days i've tried some roms from here.first i've unlocked the bootloader in developer menu,then from fastboot with the unlock key provided by motorola website,i've tried different rom,didnt like that i cannot use bank apps.so i went for locking.full reset,adb enable,reboot bootloader,full flash stock rom (last one from Motorola),reboot to check,adb enable, reboot bootloader,run command " fastboot oem lock " once ,it asked for confirmation due to data loss,then run command " fastboot oem lock " once more,then reboot to os.everything went ok,device dont show that was unlocked
