If I relock the bootloader, do I lose my warranty?
You do not lose your warranty with unlocking bootloader. It has been made clear from the Xiaomi CEO. Doesn't mean that if you unlock bootloader and toast the cpu because of wild OC and weak thermal that your warranty will work os: I'm sending rooted and u locked device since years to service without any issues whatsoever

That's what the Xiaomi CEO said in it's last intervention. You can check it. It actually will depend on your reseller and his sell terms with Xiaomi.

Hello Guys
I have a question how to look bootloader?
Because maybe if i want to sell this phone or send to service i must have locked bootloader because they are checking if the bootloader is locked or not...
i think you need a locking code, have to ask huawei for that
then use the adb command to lock bootloader
+1
if find please post!
i found something
type this "fastboot oem relock YOUR CODE"
where YOUR CODE its the unlocking code provided by huawei
try and comment
anyways, the phone will say "relocked" not "locked" as factory locked.
Confusion?

Assuming you already have your code...
adb reboot bootloader
then when it's at the bootloader and it mentions "phone unlocked"
fastboot oem lock
The lock and relock confusion ... was this ever tested with the relock command? Is there a difference?
I tried to lock back the phone with the following command:
Code:
fastboot oem lock
Phone got restarted into bootloader directly, without locking it. I read about this around the net, and found that the system may have to be unrooted in order to get the above command working.
I think, when you unlock your bootloader you never can how back.
once unlocked, always unlocked.
that is why they say you lose all warranty when you unlock your phone.
By the way, I tried to do the relocking with the TWRP Recovery installed. Maybe after reflashing a stock ROM, and flashing the stock recovery back, it'll work.
Does this work for anyone? Really need to lock my bootloader again and it's not working.

I think if you install a update.app of your stock firmware the bootloader will be locked..This may be work though I didn't check it yet.

Sadly not. Then bootloader is still unlocked.
As far as I know there's no way to relock the bootloader after unlocking it. By default it should allow such an operation, but looks like our fastboot framework was modified in this way.
works
http://huaweip8lite.blogspot.hu/2016/01/tutorial-how-to-lockrelock-bootloader.html
For unlock your bootloader
The command is :
"Fastboot oem unlock *********"
For relock it
The command is
"fastboot oem relock **********"
The stars was your unlock/lock code from Huawei.
It's the only way, other's command was wrong.
Install update don't relock your bootloader and you can update with your bootloader unlock.
It's only necessary to relock it in case of warranty.
Having his bootloader unlock is a great help when you have bad trouble like brick or softbrick.
Also you have to know exactly what you are making on your device's. And you are the only one to blame for the modifications you make on your device's
Lock the bootloader with DCUnlocker... it'll lock the bootloader without the 'relocked' on the screen.

No...Not Will Be Locked
For relock it, you have to use your unlock code too.
In fastboot type
fastboot oem relock ************
(the stars is your unlock code)
And now your bootloader become green and locked.
Sent from my ALE-L21 using XDA-Developers mobile app
And now your bootloader (maybe, i don't know for sure) become green and RE-locked.
If you use DC-unlocker it only reads "locked"

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

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.

Hi.
I´ve unlocked the bootloader on my P10 plus.
But now, the toggle to unlock OEM on the developer settings is greyed and I can´t perform any fastboot commands.
Any help?
Thanks
I believe the option becomes disabled when you've unlocked the bootloader, as you'd have to use the relock command instead of the toggle to relock it.
I assume you're familiar with accessing and using fastboot if you've unlocked your bootloader... so for the fastboot commands, does the device show up when plugged in and you run "fastboot devices"?

Maybe try re-unlocking and flashing stock rom, kernel, system, and boot. (Or you can try the method I used to update manually). Requires to be able to acces external sd card.
Hmu if you want to know how.

use reflash tutorial from this site:
HTML:
https://xiaomifirmware.com/roms/download-official-roms-xiaomi-mi-a1/
. Just download tool, extract, then exctract downloaded rom in this tool folder. Conect A1 in fastboot and start flash_all_lock.bat file in folder with room (I used flash_all.bat). This is how I fixed my bootlops...
You need to reflash. There's no other way.
Did you have the original stock Oreo with January security patch?
I would also like to re-lock the bootloader but now I have read your post I am unsure if its safe.

Maybe
I didn't try it but it may brick your phone
Developers should make clear that Re-locking the bootloader is not as easy as the unlock process and there is a high risk you will brick your phone.
