I encountered a problem with unlocking the bootloader. To unlock it, it says in the instructions to enable usb debugging and oem unlock in dev settings but then i could not find any "oem unlock" in the developer settings causing the bootloader unlocker not to work. Does anyone know how to fix this and unlock their bootloader?
my zenfone 3 5.5" is currently updated to the latest update (nougat and everything else that follows)
which guide are you using?
The official way to do it is through the Asus app here. I believe you have to use official way because you are on the latest firmware and the unofficial way only works on pre-nougat.

So i installed the latest marshmallow update on my k3 note(k50a40) and while I was checking its features I found that there is an 'allow oem unlock' option in developer settings. From what I know this option allows us to unlock the bootloader from fastboot. I wanted to root my device but I dont know how to unlock the bootloader on this phone. Can someone help me?
Hi,
I did the OTA update to N and i noticed that in developers options the OEM Unlock option is grayed out but the Bootloader is Unlocked as i can install SuperSU and TWRP.
Anyone have a clue why is grayed out?

Probably because the bootloader is already unlocked.
If your bootloader was NOT unlocked, you would have to toggle that setting before unlocking it. Since it's unlocked already you can't undo that setting.

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
I have read multiple threads on here saying that only the European version of the G6 is unlockable by using LG's bootloader unlock tool. But I just saw a "Enable OEM unlock" setting in the developer options on my G6 (US997).
Can anyone tell my, what this does?
Enabling that setting just allows for the bootloader to be unlocked it doesn't unlock it directly.

You can still unlock your bootloader for what it's worth on the us997. You'll need to have that option enabled in the Developer tools and then go to the official LG website, where you can get a flashable unlock.bin which you just fastboot flash unlock unlock.bin to the phone.
(I would post the link but newbie status)
Hi,
I've tried all the following steps in the video and I got the error "flashing lock is not allowed". I've already flashed stock rom and recovery and wiped the phone so it's as stock as it gets yet I still get the same error when I enter "fastboot oem lock". Please help ASAP!!!! I'm trying to update to Android 8.0 but the update keeps failing because my bootloader is unlocked
Thanks in advanced.

Go to developer settings.. check the oem unlock option. If it's off, bootloader won't relock. You need to turn it on. If it's greyed out & can't be turned on, then you need to root your firmware or flash custom rom & turn it on.
When you have this problem, only magisk will help you turn on allow bootloader unlocked when it's grayed out.
So, you have to flash magisk, turn on allow bootloader to be unlocked in devlopper settings, then flash a clean OOS, make sure there's no modification like custom recovery or root, then relock your bootloader.
Good luck!
use command "fastboot flashing lock" instead of "fastboot oem lock", this will lock your bootloader
hope this tutorial will help you....!!! https://www.youtube.com/watch?v=CQYCSdDUdAU
I had the same problem and solved using magistik, reenable unlock volta loader and After relock.
