Yes, I do want to flash stock rom, unlock the bootloader in order to install TWRP and Root the system but I also want to lock the bootloader again, if I do this after installing TWRP and Root what will happen? Will I lose both or just the root? Or nothing?
Also, I can use that program available on Play Store to lock the bootloader without losing the settings, this way I wouldn't lose the Root, if I would lose it using the adb command, right?
Thanks in advance.
locking the bootloader does nothing, with or without that program
if you get a OTA and accept it, you will lose your recovery and root, which means you will have to unlock the bootloader and will wipe your device.
Any one knows how to re-lock the bootloader of one plus 3???
And
How to remove that screen on boot up after unlocking one plus three??? :/
If you read the screen properly ull see the instructions on the screen itself do everything the same way you unlock the bootloader just instead of oem bootloader unlock type oem bootloader lock ...but make sure you're on stock rom and recovery

But then My root access will be wiped??
I want root access and dont want than annoying screen
two questions different answer but I would bet if there is a way to remove nag screen a google search would find it. Keep searching threads
there is no reason to re-lock bootloader, its still under warranty through Oneplus even with unlocked bootloader. but if u really want to
1. fastboot flash stock recovery (fastboot flash recovery recovery.img) (make sure u download the file, its somewhere here on the forums
2. reboot and then reboot to fastboot (fastboot oem lock) (i have never re locked a bootloader so i am not sure if it will rewipe ur device again like unlocking it does)
3. boot to OS and get developer options again and uncheck OEM Unlock (do this last)
i would not recommend re locking since it wont void warranty and seemed like a lot people screwed up their devices relocking it, but they also unchecked the oem unlock before flashing stock recovery, also i am not sure if step 2 is needed, i would just make sure u flash stock recovery 1st before doing anything
HELP

What part of be on stock OS is so hard to understand?
If you're not absolutely stock when relocking, you will brick your device.
Then good luck trying to enable OEM Unlocking when not being able to boot.
As someone who messes with their phone, relocking your bootloader is one of the worst possible things you can do.
If not done correctly, it WILL brick your device.
If you want to go back to stock, then surely do, there is absolutely no need to relock your boot loader unless you're selling your device to someone or if you're looking to pass SafetyNet for Android Pay or something.
Also, you cannot have the cake as well as eat it. You need to have an unlocked boot loader for root, exposed, etc. There is no way around this.
Phones previously had to be reverse engineered and exploited to gain root access, now OEMs freely allow unlocking.

I hope you can read this. I'm not a noob and I am looking to relock my bootloader because I am going to sell it. The person wants it fully stock so I need to relock the bootloader in order to regain access to official Ota updates.
I need to be on complete stock (stock recovery and rom) right? Would you please kindly point me to where I need to go to download the stock Rom and recovery. There's some TWRP flashable OTA zips on Oneplus forums that restore stock Rom and recovery but I want to be sure that that is enough and that I don't end up bricking my device for something as stupid as this. Any help would greatly be appreciated!

Fash 3.2.4 FW from here.
Follow all instructions from here (except I would suggest sideloading the StockROM before relocking).

I followed the same guide posted on OnePlus Forum to re-lock my bootloader. Just follow them, it works.
Here is that link from OnePlus forum.
1. I restored my stock rom backup from TWRP
2. Flashed Stock recovery
3. fastboot oem lock
4. Sideload stock ROM
Done.
I unlocked because stock ROM I felt was much stabler and hassle free. Have rooted and played with custom ROMs enough in my Nexus 5 days. Just too much stress and can end up with non-working features. Might root again in future if I find something compelling in custom ROM.

If you unlock bootloader and root device. Do you still get OTA updates if you stay on stock ROM?

If you unlock device, you will still be able to apply OTA. If you rooted by modifying the /system partition, OTA will fail, but if thou rooted using systemless method, you can apply OTA.
Iam on stock OOS 4.0.3 and i was plagued by the same error
--adb sideload the complete rom (with locked bootloader)-- method worked for me.
Previously i had unlocked bootloader and was on freedom OOS 2.3 with TWRP and then i realized that stock updates are better.
So i installed stock recovery and and tried to flash Stock Firmware 4.0.3 through sideload command and it failed.
then i installed TWRP and then installed stock OOS 4.0.3 and it installed fine but with some error.
Then i installed stock recovery
So i rebooted it and after long time it was installed but then i started getting dm_verity error and also i was frustated with unlocked bootloader message.
So i locked my boot loader first from fastboot oem lock and then sideloaded the stock 4.0.3 again and it really worked.
So now i am on stock rom and stock recovery and no more dm_verity error or unlocked bootloader msg to wait for 5 secs...
Now iam really loving my Oneplus 3..
Can i lock my boot loader with a custom rom and no root?
No, you cannot. But unlocking your bootloader does not void your warranty. If you're encrypted, even when accessing a custom recovery like TWRP, you need your decryption key to access system and your data. So it's not like unlocking will hurt security.
So I have small problem. I have to restore device to factory state (flash stock image), but I have TWRP instead stock recovery. If I unlock bootloader while I have TWRP will something bad happened?
Should I flash stock recovery first and then unlock bootloader? Or I can simply do it with TWRP?
It shouldn't matter if you have twrp. But unlocking the bootloader will wipe your device so backup anything you want first. I'm not sure if you mean you want to unlock the bootloader with twrp? That you can't do, use fastboot. But, if you have twrp haven't you already unlocked the bootloader?

Bootloader will lock itself on next boot, but that's different story.
So nothing bad will happen? I need to get rid of "device is corrupt" if I want to send device to LG for screen replacement.

Do you mean the "device is corrupt" screen on boot up. I guess I haven't specificaly tried it on my 5x, but I don't believe that will ever go away once you've unlocked the bootloader the first time. Even if you flash the stock firmware and Mick the bootloader with the device. But it's a Google device so LG still do the screen replacement.
Quick question for the masses if I'm rooted with a locked bootloader with just magisk with the patched boot image and no twrp how do I restore to complete stock? Do I need to unlock bootloader first then flash all.bat MR3 and then relock bootloader?
Thanks
Should be able to flash the stock images with a locked bootloader. Unlocked just allows flashing of custom images to an extent.
Wait you can root this phone without TWRP?

The instructions that are on the site with the factory images says you have to unlock it to flash the factory images.
