Open does not mean unlocked. Open means you have root access. Unlock means you can access the recovery partition and flash anything you want with a custom recovery.
https://forum.xda-developers.com/meizu-mx/development/recovery-twrp-bl-unlock-m3-note-t3684052 See the tutorial
With G version (6.3.0.0G), lk does not have fastboot unlock cmd. I had disassembled 6.1.3.3G lk to check and confirmed. Instead, A version does have it because of nougut port (Ie, 6.3.0.2A fw).
I knew it because tried today. I rooted and run global.sh then install A version fw on my G version phone. The drawback is fastboot USB is no longer working. So winxp PC USB connections to m3note fail. Lucky the phone still working.
So if somebody told you G version can unlock bootloader, then you have to pay attention. I assumed you less likely got the A version phone but a G version instead. If you are lucky with A version, you can have a try. FYI the above disassembled A version of lk does have below cmd:
oem p2u
oem reboot-recovery
oem unlock
oem lock
oem key
oem lks
flashing unlock
flashing lock
flashing get_unlock_ability
Many more....
Regards.

I just wanted to report that I successfully re-locked my bootloader (did not find that here).
I have an H850 with GPS problems. To return it I wanted it to be as stock as possible.
I used TWRP to flash LG-H85010E-Flashable.COMPLETE.zip from Codefire. Back to unrooted.
I also tried to flash recovery.img from the same source. This seemed to work (no more TWRP), but did not allow for OTAs (update error 0x1125000).
Then I put the phone in download mode, started LG bridge and did the "Updatefehler korrigieren" thing (German, roughly translates to "correct update errors").
To re-lock the bootloader, I put the phone in USB Debugging mode and entered the following commands:
Code:
adb reboot bootlaoder
fastboot oem lock
fastboot reboot
The phone gets wiped by this, but you need to do the initial dialog again: enable developer mode, then go there an disable OEM unlock. After that do a factory data reset one last time.
You should contact @autoprime and have him add this to his all in one thread.
Thanks for the info!

It's good to see that we have option to turn back to stock, and maybe send phone for warrianty repair. But I have one question... If you had tried to unlock phone once again, would You had to enter LG Unlock Code again?

Obviously. The command to unlock is
Code:
fastboot flash unlock unlock.bin
which means you need to have the unlock.bin file available. You did archive the mail, didn't you?

I've got the same problem - seller deceived me and sold phone after water damage. My microphone stopped work and I should send it back. How to lock the bootloader on RS988 model?
I'm holding off twrp + bootloader unlock because I want to be able to undo in case I need to use my warranty. Is twrp/bootloader unlock reversible? Many thanks
Yes. Flash complete stock everything, boot into bootloader, connect to PC, and "fastboot oem lock".
Is it sure that it works??I have a A2017G and i have open BL and a B29 Custom Rom and i want back to Lock Bootloader

Yup! I've done it plenty of times. You do need to format the data partition though. This could mean that it'll wipe out even your internal storage, so back that up as well!
Im on stock and then i go to edl and then i type fastboot oem lock but nothing happend

Boot into bootloader, not EDL.

and you can unlock it again afterwards?
Never heard of anyone wanting to lock the bootloader so I'd a newb in this kind of thing.

Locking it again is good for when you want to sell the device or send it in for warranty repair.

Yeah, the unlock procedure is the same as before. If you didn't restore the original boot image before the relock, then it's just a matter of booting into fastboot and unlocking the device. Note that this will cause your data to be wiped as well!
If you restore your boot.bin backup file from when your device was locked, does this lock the bootloader? "fastboot oem lock", "fastboot flashing lock" nor "fastboot oem device-info" does nothing for me. Is there any other way to check if your bootloader has been relocked?
Thanks

Hi there,
Were you ever able to re-lock your bootloader on your A2017G?
I just want root for now but understand that I'll need to unlock the bootloader first. Before doing that, I want to make sure I can re-lock the bootloader if needed.
Thanks for letting us know!

Guys/Gals, it is seriously as simple as using the fastboot command in reverse. I've done it a few times already with mine.
If you used the following to unlock....
fastboot devices
fastboot oem unlock
.....then you can use the following commands to relock
fastboot devices
fastboot oem lock
fastboot devices is not necessary, but I do it to make sure the devices is being recognized by ADB/FASTBOOT

Thanks for the answer.
But there are a few files to flash before using that command according to this thread.
Doesn't anything need to be flashed again (e. g. stock files or anything)?
Correct, but you would have already flashed those in order to use the unlock command in the first place.
Are you trying to relock on marshmallow or nougat?

My phone is only a few days old. I'm debating whether to keep it or not (considering the Mate 9, but the price is not the same - love the form factor and bigger screen though - sound won't be the same and I think I'll miss the MiPop button on the Axon (never thought that would happen )).
I'm on the latest MM (B10 - the A2017G model).
Following the mentioned thread, I got to the point of installing TWRP (the signed version), only to realize that besides making backups, there is not much else I can do with that without unlocking the bootloader. I really just wanted to flash supersu and install adaway fro the time being until development matured for this phone (maybe also play around with viper - had great results on my LG G4).
HI, I get the error "FAILED (remote: unknown command)" in ADB when I enter "fastboot oem lock". Any way to fix this?
Guys, can anyone help me? I really need to lock the bootloader!
How can I fix the error "FAILED (remote: unknown command)" in ADB when I enter "fastboot oem lock"?
I'm on MM B11 Stock.

Hi Guys,
The Axon 7 Model A2017U I just purchased has the bootloader locked and it is running LineageOS 14.1 - 2018032-Nightly-axon7. I need to relock the bootloader and get back to the stock MiFavor rom so that I can send the phone to ZTE for repair. Can you please explain to a newb in some detail how to achieve that.
Thank you.
Hi, few days ago I tried to install a rom stock on my moto g5 plus, but i didn´t unlock the bootloader from the system (debugging usb, oem unlock), now my phone is bricked and only enters on fastboot mode, how can I unlock the bootloader? I tried many commands, including the code sended by motorola to unlock it, but it still locked,

Unfortunately, if you cannot boot into the operating system to enable "OEM Unlocking" in Developer Options, it is not possible to unlock the bootloader. Period... There is no way around it, and since you have been issued an unlock code your warranty is void (it doesn't matter if you actually unlock or not, your warranty is voided by the code being issued successfully).
With the bootloader being locked, downgrading is not possible, and since we don't have the latest factory firmware image your only options are to wait for it to become available and then flash it.
If look at the output of "fastboot getvar all" you should be able to see what version you have installed now. You need a full factory image that is the same or a higher version for the exact same variant you have, otherwise you just have a brick... Moto won't even lock at it, even if you pay for it.
I wanted to relock the bootloader of my Moto G4 Plus as now I'm in no need of root now. And even want to remove the logo which says my bootloader is unlocked.. I used the code but it is not working still pls help me out
i think you are in the wrong section but nvm. for removing the annoying boot logo you can flash the logo bin
Code:
fastboot flash logo logo.bin
in fastboot mode where "logo.bin" is the filename.bin. you can find the logos at this link
https://forum.xda-developers.com/moto-g4-plus/themes/customized-logo-t3451349
or if you want some more cooler ones just search around.
Now comes to relocking bootloader, you must give more info(what phone you are using) and from where you got the link and what commands you pressed. you can follow this link which uses dec update or (if you check last messages even the feb update though i would recommend dec)
https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
and then use the commands given in the code OR the
Code:
OEM Lock file

Hi to all members,
I want to relock my G4 plus bootloader, I tried the guides to relock however seems there was a problem locking the bootloader after april 2018 securuty patch ( stock android 7 )
Any way to lock this bootloader ?
Many thanks
When you're relocking your bootloader, what errors are you encountering?
Make sure that OEM unlocking is enabled in Settings>Developers options, and also what device do you have? If your bootloader version is B1:07 you can use the April 2018 firmware. However, if your bootloader version is B1:09 you must use the Oreo firmware to relock - you cannot lock your bootloader with firmware older than the bootloader and you cannot downgrade the bootloader.

Alright, what commands are you using to lock your device? Are you using the OEM lock script or do your commands list include the three OEM lock commands?
Can you also confirm that your OEM unlocking toggle is on (in settings>developer options)?

Ok many thanks, my oem unlocking is greyed out ( says Bootloader is already unlocked )
I am using minimal adb and fastboot ( watched a Youtube video saying put the unzipped firmware ( Oreo 8 TWRP-athene-8.1.0-OPJ28.111-22 ) into the adbfolder and open a cmd but there is no oem lock script there !
Thanks

Mind if I ask which Youtube video you used?
That firmware zip you mentioned does not seem suitable for locking the bootloader (if it's a TWRP flashable zip as implied in the name, you cannot lock your bootloader with that). I would recommend getting the stock Oreo firmware from here https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 In addition, you could either download the OEM lock script as mentioned in that thread (it's separate to the firmware usually) or use the listed commands in the thread's procedure to lock your bootloader. I've used this firmware and those commands to re-lock my XT1642 (on the retgb software channel).
Whilst you're downloading the above firmware, also you may wish to root your device with magisk (you will have to temporarily boot into TWRP and flash magisk), which might also activate your OEM unlocking toggle. Ensure you're also signed into your Google account on your device. That should hopefully enable your OEM unlocking toggle and then permit your device's bootloader to be lockable again.
