Just go to the Gcam thread and there is a manual way to install gcam. One of the steps in the end is Bootloader lock. It is a simple ADB command.

What do you mean? The physical SIM/sad card slots?
You could either insert 2 SIM cards or an SD card.

While this is a bit off topic, I'll try to ELY5.
Basically, Slot_A and Slot_B are two separate partitions on our devices typically used for realtime OTA Updates. It shouldn't affect bootloader unlocking as far as I know.
Here's the more technical answer:

OEM Unlock can't be enable in fastboot / ADB, you'll have to reboot into normal mode, follow steps described in the link I've provided, and reboot into fastboot mode. Be aware too that that OEM Unlocking your phone will wipe your data (App, Pictures, etc).
Oh yeah, please, SEARCH next time, PLEASE, PLEASE, PLEASE!!!!!!

First off whats FRP? and if the phone is locked at this point and you cant boot it you will not be able to unlock it sorry but on the other hand you dont need an unlock bootloader to flash a stock rom but once again if the phone is locked even after you flash the stock rom it will be locked still. Sounds like you found someone phone maybe you should return it
I am in same situation. Can't boot rom adb not enabled, bootloader locked.
I cannot flash anything via fastboot, if only I could enable adb some how
Do you have USB Debugging enabled?
If you are stuck at factory reset protection you should probably enter into it using the Google credentials or your pattern.. If you don't remember them its fine. But if it's not your phone, please return back.
@ewalk4866 frp is factory reset protection that is introduced in intention of avoiding data stealing... If you reset your phone when it is locked, you have to input your old password or pattern to get pass through lockscreen pattern.

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.

You can't lock it by developer options. What you need to do is do fastboot oem lock for windows or fastboot flashing lock on Linux. Just do the fastboot command you did to unlock your bootloader but instead of unlock type lock. Then select yes on your phone and the bootloader will lock.
Thanks for your reply, I got the bootloader relocked using adb after previously not working for me, I had to update adb fastboot files
Hi could I ask because i lock my bootloader on Mi A1 but unfortunately the device didn't boot up.
Now, I am trying to unlock bootloader to fix my device and it won't unlock FAILED (remote: oem unlock is not allowed).
I am on May latest security patch build. Please help me.
Did you try reflashing ROM with Mi Flash tool? Use "Save user data" option there.

I think you tried to lock your phone after rooting your device. You'll have to try to switch to fastboot mode by volume down + power after vibration. Then use flash using Mi flash tool
I cannot do that, the bootloader is locked and I am on May security patched. Those fastbook oem unlock and fastboot flashing unlock methods won't work. I believe only testpoint is the solution to my problem.
Stuck with the exact same problem....did u find the solution

Reboot to fastboot power+volume down then reboot to edl mode by typing "fastboot oem edl" in your adb your phone will turn black. Open miflash and click "refresh" if you see "com#X" it means its connected then flash the fasboot file you downloaded in mi forums after finish press and hold power until it restarts.

make the developer settings available, within it you will have oem bootloader authorization, you need to turn it on and theoretically ready

this is a very good question! if I remember well, I read in another forum that you don't need Miunlock to just open the open bootloader in the developer settings, and then you can root it, and you just need to flash the ROM from the TWRP. to do this I think I need an OTG cable and a flash drive that you can flash, because you don't have a memory card slot
I have the same issue with the global version. I tried both "fastboot flashing unlock" and "fastboot oem unlock". I even tried Mi Unlock tool without any success. Also, they don't answer support tickets regarding unlocking the bootloader at blackshark site.
Any ideas?
