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 friends,zenfone 3 bootloder opened the lock.Now I want to close .Relock bootloader.
Ive tried asking this before for my Ze520kl, someone said it isn't possible to relock the bootloader
I would like to know if someone has an update about that...
When I tried to root my phone (ZE552KL Androïd 7.0) I installed an app to unlock the bootloader of my phone (ZE552KL_SIGNED_Android_M_UnlockTool_2016_0715). I used it and ever since, when I turn on my device, I get a warning screen saying "Your device software cannot be checked for corruption. Please lock the bootloader." It sends me to this link for information. The notification disappear after 10 seconds and androïd starts.
I was quite stupid to do that because I do not have to knowledge to properly root my device. So I give up, but I would like to get back my device without that security warning.
I have already flashed it from the recovery menu, with an sd card, wiping data and cache. But it didn't work.
Any advice?

I found this on the bootloader source:
Code:
fastboot oem unlock
fastboot oem unlock-go
fastboot oem lock
fastboot flashing unlock
fastboot flashing lock
fastboot flashing lock_critical
fastboot flashing unlock_critical
fastboot flashing get_unlock_ability
but they're all untested, trying them would make you take the risk of
killing your phone
OR
locking the bootloader
keep in mind that Asus also keeps track of system mounts as read write changes, so if you're trying to fool them, locking the bootloader won't be enough
Commands do not work.

I have a A2017U that I just downgraded to B35 using this guide: https://forum.xda-developers.com/axon-7/how-to/guide-axon-7-universal-unbrick-t3814413
I want to lock the bootloader to stop the annoying boot warning but can't get into fastboot when using AXON7TOOLKIT.
I tried flashing A2017U_FASTBOOT_UNLOCK_EDL (downloaded from https://forum.xda-developers.com/axon-7/how-to/complete-guide-to-unlocking-installing-t3561128) through miFlash but I still can't get into the bootloader.
What can I do?
EDIT: Thanks everyone! I used the toolkit to unlock the bootloader again, then locked it. For some reason I couldn't access the bootloader even though i got the bootloader ulocked warning.

You only want to lock it because of the boot warning? There are flashables to get rid of that... I dom't know which exact files there are for stock B35 or Oreo but there are some going around.
hell you could even go custom and use the splash bootstack if you wanted.
If you want to lock anyways, you have to get an A2017U B19 package and flash it via EDL Tool (or MiFlash). Right after that you'll have fastboot. enable oem unlocking then enter fastboot and issue fastboot oem lock and you're done. But it's way too overkill if you want to just get rid of the 5 sec screen

you need to flash original stock rom for your device trough edl. (rom your device came from factory,marshmallow)
then boot into system,unlock developer options.Allow oem unlock and turn on usb debugging.Now connect phone to laptop and check the dialogue on your phone that ask for usb debug.Unplug phone.
When you did this you want to flash TWRP trough EDL.
Now boot in TWRP and flash UnlockbootloaderPackage from DrakenFX.
Reboot system.
Now turn off your device and boot into fastboot,connect your phone with laptop and open ADB terminal on your laptop or use Axon7toolkit.
In terminal enter fastboot oem lock,or in axon7toolkit choose lock bootloader.
Your bootloader is now locked.
PS: you dont need locked bootloader to recieve ota's,and make sure you are on the firmware your device came shipped with!!
You need a locked bootloader to get rid of the warning message ( dont flash any mod package that claims it delete the warning page)
i am on pie 073 firmware... i want to unlock my bootloader ... all the drivers are installed even my phone is detected both in adb and fastboot mode... but when i run the unlock both normally or running uts as administrator it doesnt work... nor the application of unlockimg boot loader works on my phone
Did you try manually typing the unlock command?
Code:
fastboot oem unlock
I've tried this , but it says
Comman failed
No error...
I also has the same problem

You need to download the Asus Unlock Tool.
If you still have issues, go to their forum ZenTalk and they can help you. They are very fast.
