Have you unlocked the bootloader first?

yes it is already unlocked previously. i just did a new clean wipe for the phone and flashed the mtc19x factory image

Try this:
fastboot oem device-info
It will confirm if it is unlocked...
Also try to boot twrp by:
fastboot boot recovery_name.img
Both commands will confirm the same.

Is it possible to relock the bootloader?

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.

Flash Recovery -> FAILED (remote: Command not allowed)

Hello Guys,
After serveral month with TWRP & other stuff I've flashed stock B161 today.

And got the alert:

Yes, Bootloader is unlocked.

it's some kind of bug i think, it says it's unlocked, but it isn't, try unlocking again. it's only unlocked if you get a warning everytime you boot up the phone

try unlocking again, it should work after that
when you flash a stock rom, the bootloader gets locked again, but for some reason it still says unlocked in fastboot mode. it's probably to prevent you from restoring warranty after unlocking your device

Thank you!
You are right, the warning-message isn't there anymore.
I will try to unlock it again tomorrow, I hope that it work without problems.

Rescuing data, defective touch, no: debugging, twrp, bl unlock ...

Recurring data defective touch.
So touch has died on my friends n4 and he’s coming over the next days asking me if I could help.
Of course stock android locked, bootloader, no twrp, no usb debugging.
If I recall right the n4 does not need an OEM Unlocking flag or something, also it shouldn’t be encrypted, right?
Do you think I can just simply oem unlock it, flash twrp and use it to backup the data?

Nice thanks, wasn't sure if this phone got some protection at some point.
Or if unlocking comes with a force wipe.

Yes, unlocking the bootloader will wipe everything that is on the phone... Use with caution.

I can't manually install any ota update after locking the bootloader on 12.0.9

I don't want to unlock the bootloader again and i don't like this update because it doesn't have google discover.. what can i do?

You can just stay on current version.
Or just install via fastboot and fastboot ROM

Without unlocking the bootloader? How?

Ok, so you stated that bootloader is locked, I thought you are considering locking it again.
In that case you have no option, but unlocking bootloader to flash different miui ROM
