Re-lock Bootloader Help - OnePlus 7 Pro Questions & Answers

Hi,
I haven't done anything in the way of rooting or custom recovery or anything. I did unlock the bootloader first thing due to the wipe that occurs as part of the process.
How do I relock the bootloader? I did some research and all that I've found so far is people cautioning for past OP devices about the standard relock procedure so I just wanted to ask the question to make sure I don't break anything.
I am on Stock everything so can I just fastboot oem lock?

Yep, that should be it as long as you didn't root.

Awesome thanks. Yea no root yet for me, all I did was unlock the BL so I didn't have to wipe my phone later.
Thanks!

You do know that any time you unlock or relock your bootloader it will wipe your phone?

Yup that's why the first thing I did was unlock it. Now I am relocking it since I don't intend to keep it.
Thanks!

Maybe I'm confused but why did you unlock it in the first place if you were just going to relock it?
Edit: I think I follow now, you unlock the bootloader when you first got the phone and now you're not keeping the phone so you're relocking the bootloader?

I got the phone, unlocked it so I wouldn't have to wipe later, used it for a week, decided it's not for me, and am relocking it.

Yes, make sure to backup your TA first, otherwise you can't relock it again.

Does rooting your phone void your warranty?

I want to root my honor 8 L04 but I was wondering if it will void my warranty.
Thanks,

Yes it does and the current method for rooting is kinda sketchy at this time. I'm waiting untill the lineage ROM is done and hopefully by then we will have a better rooting method.

Yes you can relock the bootloader, however it will say relocked bootloader and not locked bootloader like it originally said so you can still see that the bootloader had been unlocked at some point.

To get the status "locked" back you have to downgrade to emui 4.1

I have one question, if I had unlocked bootloader, installed TWRP and rooted my phone, then unrooted it, reverted to stock recovery and relocked bootloader, can I still receive OTA updates?

You don't. You know the saying.... Once you go bootloader unlocked, you never go back. :laugh:
There's a DRM fix which brings back camera and other functionalities that are usually lost on unlock. So use that.
