to relock the bootloader, the device has to have a 100% stock rom on it, no modifications at all.
ADB isn't used to relock the BL, it has to be done with fastboot.
To get fastboot on the device you have to use qfil and flash the engineering abl and then go directly to fastboot from qfil.
Look in the guides section and you'll find threads how to get the above done.

there are multiple guides in the guides section re this. They may be for unlocking the bootloader, but in your case you follow it and instead of oem unlock, you type oem lock.

[Q] Nexus 6 LOCKED - TWRP installed, and running??

I attempted to flash and unroot my Nexus 6 via Wugfresh's tool, and thought it was a success. I hit 'relock' and now the device is bootloader locked with no OS installed.
However, I can connect via fastboot so far, but I am not very good with it. I think I may also be able to push files, but when I attempted to flash SlimLP the device just reset.
TWRP is still present on the device, but I cannot unlock my bootloader without getting a ROM on there... So I am stuck...
I need to mail this phone back in tomorrow for cracked screen, so I am hoping someone can help me. Thank you.

First check here... http://forum.xda-developers.com/nexus-6/general/how-to-nexus-6-one-beginners-guide-t2948481
Get the sdk tools and once set up, see if you can do adb devices and have the phone show up on the PC, if so, do adb push (name of rom file) then boot to twrp and install. If that doesn't work, check the same page above (since you don't have an OS not sure what would happen) try the unlock instructions for fastboot ( I would wait for someone else to comment before trying this). You might want to message this user http://forum.xda-developers.com/member.php?u=2872010 rootSU and see if he can give guidance, he has lots of experience.
Locked Bootloader
I still can't seem to get past the fact that my bootloader is locked...
Thanks though.

Try this: Reboot to bootloader, select recovery mode, enter TWRP, mount MTP and push/sideload and flash a flashable image from here http://forum.xda-developers.com/nexu...tboot-t3066052.

Hey, thanks for the tip.
The link you sent was dead, and can you help me understand the commands for flashing in ADB with a locked bootloader?

Sorry my bad, here it is http://forum.xda-developers.com/nexus-6/development/fxz-nexus-6-recovery-flashable-fastboot-t3066052.
Follow the instructions as i posted, place the download rom in the /android-sdk/platform-tools/ folder and boot in bootloader and select recovery, select adb sideload there and type in cmd: adb sideload name.zip.
Unlocked Bootloader
The thread says they are for unlocked bootloader only.
I have TWRP installed, but for some reason at one point my bootloader was relocked.
So now I have No OS to 'enable oem unlock' to unlock my bootloader.
This is my issue.

I don't understand, what do you mean it worked for other users? The thread specifically states the bootloader has to be unlocked, and unfortunately I do not have an unlocked bootloader.
So I cannot fix this issue unless I either get a rom to flash with a locked bootloader, or somehow force unlock the bootloader

Huawei p8 lite 2017 bricked after wrong oem flash

(SOLVED) So I wanted to debrand my phone, and I saw this post https://forum.xda-developers.com/p9/development/c432-oeminfo-flash-twrp-t3384903
problem is, the oem I flashed with twrp was for the p9 lite, now my phone doesn't boot inside the os, it only goes to huawei erecovery but the download always fails. I can boot to fastboot mode but everything I try to do it says command not allowed, only fastboot devices work
I hope someone can help me as I really need my phone for work, thanks very much
my original cust was C02
I also have a twrp backup I did, but I just cant get inside twrp because as soon the phone turns on it goes to erecovery
Edit: i finally resolved and I'm going to really help you if you flashed the wrong oem file just like me, just follow these steps:
1. since you installed a new oeminfo, you are gonna need to unlock the bootloader again, (just like you did the first time), but wait! here is what I did wrong, when you request an unlock code, huawei in the unlock page is gonna ask you for your imei and serial number, I was lazy and I got my imei via fastboot instead of checking the one on my phone's box, worst idea ever because when you flash another oem your imei is gonna change so that's why in the site it said sn and imei are mismatching, so take the IMEI on your phone's box and NOT via fastboot. Anyway, let's go to part 2
2. in the unlocking site they are gonna ask for a product id wich you can get by writing *#*#1357946#*#* in the phone's dialpad, but you're probably thinking "how can I do that if my phone does't boot the os?" but don't worry my brudda! just download this https://cloud.mail.ru/public/KGmS/1cEhHg1G6 , open it and chose huawei y300-0100 as product model, then put your IMEI (take the one from your phone's box!!) and it's gonna give you the product id you need in the huawei site.
3. once they give you the unlocking password, power off your huawei and connect it in your pc with your usb while holding the volume down button, you should go in fastboot mode
4. once you are in fastboot mode write in the cmd fastboot oem unlock (9982883838382365) <<(instead of this numbers write the unlocking password they gave you in the huawei unlocking site) aaaand done, you unlocked the bootloader once again.
5. if you previously had twrp (before flashing the wrong oem file) it's gonna pop up when you boot the phone, now you can use fastboot or twrp again to flash the right oem (or stock rom)
I REALLY HOPE I'M GONNA HELP YOU BECAUSE I KNOW HOW BAD IT FEELS WHEN YOU BRICK YOUR DEVICE LIKE I DID!!
Now bye everyone I need to go play soccer and I'm late

but when I click on commit after writing all in the huawei unlock site bars it says SN and IMEI are mismatched
I mean you really f***ed up there. I thought that you could restore the device by eRecovery but If you would do that you would brick it completely bc it would Download everything for the p9...
you can't do anything without the unlock Code.
You could otherwise try to force upgrade via dload
---------- Post added at 09:05 PM ---------- Previous post was at 09:02 PM ----------
You could try this Generator https://cloud.mail.ru/public/KGmS/1cEhHg1G6
or DC unlocker (costs money)
You can use Firmware finder for PC and eRecovery DNS method to restore your phone to any firmware you want

If that dosent work you can also follow the below procedure.
Relock your bootloader. Your phone will factory reset and boot. Then head to developer options and you will see oem unlock is not greyed out. Then just enable oem unlocking and unlock the bootloader. When you boot up again you will see that oem is greyed out but it'll be enabled. So you'll have unlocked fastboot and unlocked frp now.

I haven't gone that far. I've unlocked and then relocked.
Everything fine. I believe it's completely safe if you have complete stock firmware installed ie, stock rom, stock recovery, stock Kernal and all that stuff. Otherwise you'll end up in a loop. Guess I forgot that part sorry.
So I know this is someone else's thread but can you tell me if I relocked bootloader will the service center be able to know I'd unlocked before? I don't have the phone unlocked warning at boot. Just curious.

Some if not all bootloaders nowadays are not "locked" by the manufacturer using a code but are usually "locked" by employing a digital signature and/or a CID (carrier Id) hard coded into the OS. When we "unlock" a bootloader with a code we are simply using a routine written into the loader by the manufacturer to now ignore signatures and/or CIDs of the OS and this allows us to flash whatever we wish.
Sometimes upon unlocking using a code the DS/CID is erased/altered and cannot be retrieved, so not a good idea to relock an altered bootloader.
At least, that is my understanding of it.

Unlocking bootloader: definitive bye-bye to automatic updates?

With the Moto Z, after I returned the phone to stock (flashed stock firmware and locked the bootloader), I'd be able to flash stock firmware with the flashing locked.
Not so with the Motorola One Zoom. In other words, flashing stock and re-locking didn't return the phone to its pristine state. Even when flashing stock firmware over stock firmware, I have to unlock the bootloader.
Differences I observed: on the bootloader screen, when re-locked the Z would show "oem_locked" again. On the One Zoom, it shows "flashing_locked" instead. I'm pretty sure it showed "oem_locked" before unlocking.
WIth the Z, every time I wanted to unlock the bootloader, I had to issue "fastboot oem unlock" followed by the unlock code. The code isn't necessary with the re-locked One Zoom.
In other words, maybe it was a one-way trip. It seems that the phone won't return to its original state, it looks it's modified for good. And I'm afraid this means bye-bye to automatic updates.
Am I missing something here?

Question Motorola G50/Blu G50

Im trying to unlock the bootloader on this phone. with no luck. Ive followed various guides on here.
fastboot devices/adb devices both recognize it. I was able to get the token identifier. which i used on motorola's website for the unlock.
it first told me that it was missing a puid... then it told me it couldnt be unlocked. i used adb reboot-bootloader to get the phone into fastboot mode. 95% of the commands come back failed (remote not implement)
I need help please.
Thats lame. I really want to mod this phone

Hello!
If you want to unlock the bootloader of G50 you need special fastboot from Motorola. Im attaching it in reply. Also you need to have bootloader unlock code.
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a/ here you can optain your code. You can ask me if you need more. Also i made a guide how to install GSI on moto G50 if you want.
I hope that i helped.
