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.

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.

same for my devices, anyone know how to flash rom with locked bootloader?
Hi friends
Please give me suggestion or guide how to solve problem about handset booting after mistakenly handset OEM locked through fastboot
It enter to fastboot mode but not going to recovery mode or restart in system mode
Is there any solution
If yes then please help me
fastboot oem unlock ?
Actually ive unlocked OEM and install twrp recovery and installed freedom os
Then while checking OEM status ive enter command fastboot OEM lock
It ask me I've pressed yes after that the massage is came after restart as your device is corrupt it can't be trusted and will not boot
After that it enter to fastboot but not going to recovery mode or system
While type command in fastboot OEM unlock massege come failed
This happens because your bootloader has been unlocked at one time. There is no going back, even if you use "fastboot oem lock" later.
Edit: Just noticed the part about your device will not boot. You need to find the system image and flash it. I read somewhere today that OnePlus just released the system image for 4.7.4.
Can you unlock again?
@op, IMHO the best possible solution will be to flash stock rom image and stock recovery if required but I think when you flash stock image it will also flash stock recovery.
When you turn off the phone and boot it with VOLUME UP plus POWER, this should send you straight away to Fastboot. Try if you can unlock again, otherwise... bad luck - you'll need a restore session with 1+.

Not to be unrespectful, but you're wrong, it is absolutely possible to relock bootloader without problems.
IMHO, trouble happened because he had a custom rom onboard... and a locked bootloader does exactly its purpose... to not boot insecure firmware!

After looking into it further, I agree with you. That's what I get for having a bootloader-locked Samsung device for two years. I must be getting rusty!
Yes, the bootloader can be re-locked. There may still be a tamper flag as with previous OnePlus devices. But having a locked bootloader with non-OEM software would likely cause the problem he is describing. So, he needs to flash the factory image from bootloader.
I've requested to 1+support for restore remote session
Support send me file link and l2 will assist me in within 2 days
DO NOT RELOCK BOOTLOADER UNLESS U READ UP FIRST!!!!!, its worth just waiting the few seconds after reboot, then to go and try to relock the bootloader

Did you by any chance re-lock the bootloader with a custom recovery and custom ROM flashed?
It's because of custom recovery.
Just flash stock recovery image before locking the bootloader.
This fixed for me.

You unlocked bootloader, flashed rom (custom) and relocked bootloader? Never lock your bootloader on a custom rom! Just enter fastboot again flash twrp (manual/force reboot recovery), copy internal storage to pc then wipe/format everything. Format data. Factory reset then flash latest official rom and reboot

Make sure to enable USB debug in developer options again.
And did you turn on OEM unlock in developer options again also.

I know you probably enabled the options when you first unlocked. But did you enable them again after your device was wipe from the unlocking process?
Can you boot the current rom on your device?
If the rom is not booting, you may need to try and flash stock fastboot rom in EDL Mode (If that is still an option for this device).
Edit: - As you locked the bootloader with fastboot command, have you tried the fastboot unlock command
Code:
fastboot oem unlock
What response are you getting from "fastboot devices" while in fastboot.
also what is "fastboot oem device-info" reporting?
Hi,
Like the title says, my Pixel XL is bootlooping.
The only thing that works is getting to bootloader, I can't even get to recovery without it booting again. The biggest problem is that it's OEM locked and obviously I can't unlock it via developer options.
Is there any way to unlock it without booting to the OS?

OEM unlock must be toggled before unlocking bootloader or CMD won't work, Can't you flash stock OTA in the recovery? https://developers.google.com/android/ota You can sideload the zip and should flash it to save your device once you get into the OS unlock your bootloader and avoid a situation like this again

Hey, if you can get into the bootloader, there's a high chance you can use fastboot. Using a computer to install adb/fastboot and then using the command line to run
`fastboot reboot recovery` (without the ticks)
Worth a shot, but if you can't get into recovery, I'm afraid the recovery might be failing as well.

I've tried that as well with no success, it simply starts boot looping again.
I read somewhere about EDL mode, does something that like actually work for the Pixel?

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.

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
