Bootloader Relock Issue? - OnePlus 2 Q&A, Help & Troubleshooting

Hi I've read some people have problem in the Bootloader Relock procedure. Some people said that when they relock their booloader (Maybe for re-selling purposes) after relock the device won't boot or bricked. Is this true for all units? Because here I found someone who relocks his bootloader and looks fine:

Can someone confirm? I also want to try to relock my bootloader but I'm worried about the issue.

There is no way of doing it at the moment, not sure there ever will be.

If it's still locked, do you mind keeping it that way for just a little bit? It's possible we can figure out how to re-lock if we can get a bootloader dump. It's also possible that unlocking your bootloader will report to ASUS that it's been unlocked and it will void the warranty even if we can figure out how to lock it back up.
Maybe try this tool: https://play.google.com/store/apps/details?id=ma.wanam.partitions
And then report to this thread: http://forum.xda-developers.com/zenfone-2-laser/general/ze600kl-official-bootloader-unlock-t3273263

Bootloader unlocked warning?

Anyone found a method to remove bootloader unlocked warning?
That's annoying me too!
Can you lock the bootloader again after Root?

You can, but it will cause a bootloop. Before relocking your bootloader, you should unroot first.
Good to know. I'll just live with the black warning I guess

And if you re-unlock after bootloop it will work again?

Magisk don't work after you lock the bootloader. I tried it and it ends in a boot loop everytime I did it. So stop speaking nonsense.
I did something like this
but I can't remember if it was exactly this one. At least i removed the floodlight at startup xD

Don't relock bootloader with MM ROM.
(if you already have N firmware, right now)
After flashing MM, you will receive OTA for N, and it will brick your device.
Do it with latest N september patch (available in guide section)

You can, but you need to remember that "don't take OTA in future, never tap update notification"
Also if you sell or give your phone to someone else, give them latest N.

Yes, fastboot commands are same.
hi! i know this is something irrelevant but since this is related to bootloader unlocking,i wanted to question that if i wanted to relock my bootloader which was on the sept 01 patch when unlocked;would i have to flash the same build from the fastboot again to relock it?and will it be safe to install ota updates after relocking the bootloader and reverting to the stock rom?

Only for taking OTA, locked bootloader is not necessary, you can take OTA with unlocked bootloader too.
things to take care of,
don't flash older firmwares than you have at the moment,
As you have september patch, flash september (while relocking too), don't downgrade.
If you downgrade, then don't take OTA. Warned..

My bad!
GPT and bootloader won't get flashed if you downgrade, it will fail, you can't flash older versions.
I don't know if it's possible to lock without flashing them, You can try flashing without GPT and Bootloader.
Just a suggestion! You don't need to flash the firmware again, if you are already on it. For eg, If you are already on Sept patch and want to relock, you don't need to flash the ROM again to relock it. Just use the fastboot commands.
I would recommend to leave it unlocked, because if anything went wrong with your device, atleast you will be able to save the data of internal memory atleast!
