I recently saw that OEM unlocking toggle is working. I unlocked my bootloader long ago. I'm on stock Oreo right now and I didn't "RELOCK THE BOOTLOADER" but it shows to me as if it was relocked. Is it possible? I already have magisk installed. Dunno what to do. Any suggestions?
The OEM unlock toggle in Developer Settings means nothing once you have unlocked the bootloader. Make sure it is enabled and check the bootloader manually... To my knowledge it is impossible to relock the bootloader without a signed image.

I have never really seen this asked, and I am not just asking about the 6p but any Nexus or near stock phone with an unlockable bootloader (Motorola).
I have seen some claim they could not reflash their Nexus at all due to "allow OEM unlock" disabled in GUI. Others say if it is same stock ROM as currently installed, you can reflash the same stock ROM over what is there with bootloader locked.
If true, what if security patches are installed? I know flashing 6.0.1 over 6.0 requires unlocked bootloader. I am not talking about a rooted or modified phone in any way.
Just can the same image 6.0 for example be flashed on phone with 6.0 if bootloader is locked? What if unlocked, but gui has allow OEM unlock disabled?
Thanks.

On Nexus 5X and 6P, if the bootloader is locked and OEM Unlock is disabled, one can either update via OTA or ADB sideload the update.zip via stock recovery...if using the stock rom.
I cannot speak on any phone aside from 5X and 6P.
Edit: I have not tried it (no reason to) but if bootloader is unlocked, with OEM Unlock setting later turned off, you should still be able to flash stock images via fastboot. The way I see it, the bootloader is still unlocked, which allows for factory images to be flashed in fastboot. You can still OTA or ADB sideload.

If the bootloader is unlocked you can flash with fastboot, the "allow OEM unlocking" toggle has nothing to do with the ability to flash, it only controls whether the bootloader can be unlocked or not. If the bootloader is locked you can't flash anything at all, regardless of whether it's the same build or not, it's undeniably impossible to flash anything with a locked bootloader.
Updating to 6.0.1 from 6.0 doesn't require an unlocked bootloader, you can use the built-in update system to take the OTA update.
To answer your last question (and repeat myself), no you can't flash anything with a locked bootloader. If you''re unlocked but the GUI toggle is set to disallow OEM unlocking you can still flash because the bootloader is unlocked.
Some advice:
Leave the GUI toggle set to allow OEM unlocking. Leave the bootloader unlocked. Sometimes updates fail and the phone ends up in a boot loop, if your bootloader is locked and the toggle set to disallow unlocking you'd essentially have yourself a brick.
To clarify, I am not talking about ota or sideload of ota. I want to know about flashing 6.0 full over 6.0 full if bootloader locked. Let's say something is corrupted and phone isn't booting to GUI.
Is it possible to reflash same full image if bootloader locked. Forget the OEM toggle in GUI.
Surely someone knows for sure, or is curious.
Sorry, I see you answers and confirmed what I thought. Flashing anything but OTA is impossible. Missed that scrolling to fast on mobile.
several questions in no particular order:
Does the "OEM Unlocking" toggle do anything on the XT1572?
If I issue the fastboot OEM LOCK command after having sucessfully unlocked the device before, do I need to go through the full data wipe+send oem data+flash unlock code process again?
Lastly, I was able to flash the MM firmware for my Single SIM AISA model XT1572 despite having the bootloader locked (I think).
Is that normal that I can flash the official moto firmware using just fastboot without having to tweak with anything else?
I presume that since the digital signatures are correct the bootloader has no issue accepting the MM files.
Not quite the end of the world if I have to wipe everything and start over (it's only been a day) but I regret not knowing earlier. Nor did I expect to get this far with a relocked boot loader. Was trying to add SuperSU and found that while I can overwrite flash the stock recovery I cannot flash TWRP.

As far as I am concerned relocking the bootloader wont wipe your data and yes about the question regarding the stock firmware
PS: Dont relock your bootloader once you unlock it the warranty doesnt come back even if you lock it again
So I unlocked the bootloader through Moto's site. Now I want to relock the bootloader. I went through Moto's instructions and flashed the files for the X1625, however when I go to fastboot oem lock, it just says flash valid android system. It will boot up and run correctly, but it still gives the warning message and will not go back to "locked" status.
Thanks for any help
I have Moto g4 xt1624, my device is unlocked
And I tried so many time to lock and unlock and it's worked every time it's lock bootloader because I have signed stock image which is nought.
But now I have unlocked bootloader and I am trying to lock bootloader and when I run command to lock bootloader it's showing " bootloader image State invalid" so now what to do ? I don't understand please help me
Hi, few days ago I tried to install a rom stock on my moto g5 plus, but i didn´t unlock the bootloader from the system (debugging usb, oem unlock), now my phone is bricked and only enters on fastboot mode, how can I unlock the bootloader? I tried many commands, including the code sended by motorola to unlock it, but it still locked,

Unfortunately, if you cannot boot into the operating system to enable "OEM Unlocking" in Developer Options, it is not possible to unlock the bootloader. Period... There is no way around it, and since you have been issued an unlock code your warranty is void (it doesn't matter if you actually unlock or not, your warranty is voided by the code being issued successfully).
With the bootloader being locked, downgrading is not possible, and since we don't have the latest factory firmware image your only options are to wait for it to become available and then flash it.
If look at the output of "fastboot getvar all" you should be able to see what version you have installed now. You need a full factory image that is the same or a higher version for the exact same variant you have, otherwise you just have a brick... Moto won't even lock at it, even if you pay for it.
