I did not see this posted anywhere, nor do I see it on Google's Factory Image website/instructions.
Based on testing... When re-locking the bootloader, "fastboot flashing lock" does NOT seem to lock the critical partition.
After following Google's steps to a T and locking the regular bootloader, It was indeed locked. I even attempted to lock regular bootloader again, and received a message stating it was already locked. Bootloader screen also says everything is locked. All is fine and dandy, right?
For ****s and giggles, I tried performing "fastboot flashing lock_critical". It indeed asked me if I wanted to lock the critical partition. After re-locking critical, I was not able to lock critical again. Safe to say, critical does not get re-locked when re-locking regular bootloader.
Safe to say... to re-lock the bootloader completely, you probably want to perform "fastboot flashing lock_critical" then perform the regular "fastboot flashing lock".

Oh believe me, I agree. I thought it was strange re-locking the critical isn't part of Googles Instructions. Not even sure if it matters, but just an extra security precaution
Thank You very much for the heads up. Saved me a headache
So the process for stock and locked would be to install a factory image to wipe and bring back to stock, fastboot flashing lock_critical, and fastboot flashing lock?

Hmmmm what about if you are worried about theft. You can still wipe the phone and login with another account can't you with the bootloader unlocked? Where as the phone will always be tied to the last google account logged in if the bootloader is locked, making the phone useless to sell even overseas. I could be wrong though.
When re-locking my bootloader on my Pixel 2 XL, I only needed to enter "fastboot flashing lock_critical" first. When I entered "fastboot flashing lock" afterwards, this error was returned:
FAILED (remote: ' Device already : locked!')
Seems you only need one step not both. My device is now 100% stock and bootloader is locked and ready for RMA.

Clean fastboot the factory and let it wipe your device. Then factory reset, then lock the bootloader. You must be 100% stock before you lock it down my friend :good:

So a while ago I rooted my phone but messed it up because I uninstalled a few too many system apps. I just dealt with it for a few months since I could still make calls (but not much else). I finally bit the bullet to look into flashing the stock rom again, but to do so it looked like I had to install a custom recovery, but to do that, unlock the bootloader. So I first unlocked the bootloader using motopocalypse (batch file didn't work but apk did), and got the expected BOOTLOADER UNLOCKED message at bootup, with fastboot saying unlocked, code 3. I then tried flashing CWM recovery via Rom Manager, and it seemed successful, but I was unable to boot to it either from the UI of ROM manager or from holding the buttons during bootup, it would just hang for a few more minutes than normal at the BOOTLOADER UNLOCKED screen, then boot up like normal. So I kept reading, found RSDlite, and was able to flash the stock rom, which I downloaded from the internet and the phone boots up fine, but now fastboot says locked, status code 2, and motopocalypse does not unlock it again (either the batch file or the apk), but I still get the BOOTLOADER UNLOCKED message at bootup. So I'm not sure if my bootloader is unlocked or not and if I can proceed with installing CWM recovery again, so i can make a full backup in case I mess something up again.
So how do I reunlock the bootloader, or verify if it's locked or not?
First, CWM and TWRP aren't official for this phone, so you can't use their apps to flash. You'll need to use fastboot, Flashify, or Rashr. Second, you're still unlocked, we've seen this error come from bad flashes. What is the complete text on your FB screen. You should be able to clear this by re-flashing with RSD. What firmware did you attempt to flash?

I think your boot loader is still LOCKED. Mine is showing UNLOCKED. Status code: 3. You cannot flash a custom recovery on a phone with a locked BL. You need to motocalypse again!
To trace the issue from the ground up, if you're just trying to reinstall stock ROM, you should be relying on RSD instead of trying to mess with custom recoveries and BL unlocking. Just flash .10 (not .15) via RSD, root via Towelroot and you can start fresh.
Unlocking your BL is still highly recommended, though, 'cuz it's now or never.

Yes, that's why I'm asking. So I've got one vote for unlocked, one for locked. As I said though, motopocalypse isn't working a 2nd time.

I would like to flash custom ROMs later down the road, but for now I just want to get the stock stuff going.
On a side note, the version of the image I downloaded was 183.x.x, but my mother, who has the same phone, purchased at the same time, and has never rooted it or anything, has version 182.something, and that is also the version I had before I started messing with the bootloader/recovery stuff. The two versions were released at the same time, but I don't know what determines which version you got if you just did OTA updates, or if it even matters. Speaking of OTA updates, the version I downloaded is prompting me to do an OTA update now to another 183.x.x version. I wonder if I'd be able to grab the 182.x.x ROM from my mom's phone without rooting it via fastboot or something.
The 182/183 does not matter regarding root/boot loader unlock its the .10/.15 that matters do not take the .15 without unlocking your boot loader....
We cannot teach people anything; we can only help them discover it within themselves.
So no other thoughts? What would happen if I flashed a custom rom/recovery with a locked bootloader? I tried flashing the ROM again and fb still says locked, code 2, and motopocalypse still doesn't do anything like it did the first time.

It won't let you flash a custom recovery. This is the difference between locked and unlocked.

If your bootloader is relocked for some reasons, try unlocking it again with

fastboot oem unlock

I guess what I'm asking is, will it let me flash it but then the phone won't work or will give an error on boot, or perhaps brick my phone? Or will it just not flash in the first place? Because if it's the latter, then I can just try to flash a custom ROM/recovery and if it works then I know it's unlocked.

Still locked code 2 though. Looks like it wants an unlock code from Motorola's website, I tried following the steps to get the code but it says I'm not eligible for bootloader unlock. So unless there's another way to get the unlock code...

A "Code 0" locked device would refuse flashing an unofficial or older recovery. I have no idea about Code 2 though.
From what I was able to locate status code 2 indicates that the bootloader has been unlocked and relocked like by doing the whole "fastboot oem unlock unlock code" then the "fastboot oem lock" ... I'll look more into it but from what little I read it looks like it can not be unlocked again with out the Motorola unlock code...

Same here, I can see what it means but cannot find any way to get back to code 3 other than using the unlock code from Motorola, which I am unable to obtain because it says I am not eligible. Surprising that someone hasn't cracked the unlock code yet or made a keygen, people are so eager to do it with pirated computer software before the software is even released.
I've read of someone getting locked status code 2 b4 from flashing an older gpt with rsd (if I remember correctly) I think all that was required to fix it and get unlocked again was to flash the latest gpt. Very important..... Are you sure when you were unlocked you didn't ota update to .15? Because flashing .10 gpt while on .15 may be what caused your false relock
Nope, no OTA update to .15. The ZIP I have of the rom does include the gpt.bin file with the same timestamp as all the other files. I suppose I could try reflashing the whole rom once again later...
Hmm strange, I went to find the old thread I read about the gpt relock issue but it's not exactly the same as your situation.
http://forum.xda-developers.com/showthread.php?p=51436123
Until now I didn't think relock was possible due to the way unlocking works. It's a physical change, a qfuse was blown when the motopocalypse apk was run the first time. It can't be unblown lol. Wish I knew what went wrong here.
Is there any way I can unroot my G4 and re-lock the bootloader (fully, removing the message), after doing it I realise I might not get OTA updates and the reason I rooted in the first place is no longer needed. Thanks

Reflash stock firmware via fastboot, then issue command "fastboot oem lock", although it'll change the bootloader state to "relocked" instead of the factory "locked".
I was at work when i entered a bootloop. I was doing nothing special maybe using the camera. I was bootloader unlocked rooted on latest twrp and on the latest official dirty unicorn I think 10.4 and everything was fine.
After the bootloop started I tried entering recovery in which it only boot loops. I can only access the bootloader screen. I Can see my device in fastboot devices.
I think my next step is to flash some Google factory images in fastboot. But I was wondering if my device be encrypted with fingerprints and a pin will affect it because I've ran into a problem last year when flashing a new version of TWRP it asked for passcode when one was not set.
I'd love to be able to recover some of my data but I guess if it's Encrypted that is not a chance, so I guess I will fastboot Flash the original images.
Is there going to be any problems when I try to flash Nexus images while it is encrypted with a passcode, Any suggestions?
Yeah, standard answer here is to flash the fastboot images. It'll be wiping/overwriting system and vendor so you shouldn't have any issues with the previous fingerprints. It'd be a good idea to wipe data once you get into TWRP afterwards but I wouldn't worry about wiping/formatting userdata.

It's worth trying the latest (MTC20F) images first. And if that doesn't work I'd try formatting userdata too.

Hopefully Huawei or Google won't care if my bootloader is unlocked although i did Flash the factory images and unrooted it

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!

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?

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

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"?

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.
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?
