Locking you bootloader while TWRP and Magisk are installed will give you a guaranteed brick. Use a Fastboot Rom to return to stock, then you can lock it
If you want to keep TWRP and root, do not lock the bootloader. As the user mentioned above, you'll brick your device.
if i flash stock rom, than is that ok to lock the bootloader ? and how to lock it ?

If you flash a full stock rom then yes. All you do is use the fastboot rom we talked about earlier, let the phone boot up (don't bother completing the setup process, just let the phone boot up), restart to bootloader, and use the following command from the command prompt on your pc:
Fastboot oem lock
It will give you a menu on your pone asking if you want to lock the bootloader. Tell it yes. It will then lock the bootloader, factory reset the phone, and then boot up normally with the bootloader locked. It's that easy.
ok thanks.one question. is that important to flash the stock rom using fastboot only ? or can i flash it using twrp ?

I did it through twrp, worked just fine. Make sure to wipe beforehand though, don't want to risk bricking your phone

Doing it with a Fastboot Rom will guarantee that things needing wiped will get wiped. When returning to full stock I will always recommend the Fastboot Rom just because of how it completely handles everything it does flawlessly. I imagine flashing a full rom in TWRP will work but I have never tried to return to stock this way
i did try stock using twrp and it was perfect
I have unlocked bootloader but in the end NOT installed TWRP or root (just wanted to test if i can live without it and still be able to install without wiping everything)
Now I just want to lock bootloader again for selling device.
Can I do so with simple fastboot command "fastboot oem lock" without bricking phone?

Use msm download tool to be sure. It will however wipe all.

You can, but if you are selling the phone I would still use a fastboot rom just to be sure everything is wiped and no data sensitive to you is being sold along with the phone.
Thanks a lot for the shared info here. This is just what I need and had been asking myself for quite some time now.??
So never lock bootloader with twrp and magisk installed.

Okay so, first things first:
I can boot into both Recovery AND Fastboot
ADB Sideload does NOT work in my TWRP
Tampering bit is true and bootloader unlocked is false
My problem now is;
I need to unlock my bootloader because right now, my phone has no OS. I can't unlock it though because neither fastboot oem unlock works nor through the OPO Toolbox/Toolkit.
I can't flash anything to it right now and I need to find a way to unlock my bootloader, whenever I try to unlock it, it reboots to TWRP.
Please help. <3
adb push yourrom.zip /sdcard
Then just pick the ROM you just copied onto your phone storage using the above command in TWRP and you should be fine.
If that doesn't do the job then you can always use the brick recovery download tool.

Did you try flashing the OPO factory image and then start from scratch?
I was installed with Twrp and had rooted my oneplus 3.
I unticked root access in supersu.
Booted to bootloader and typed on my pc in command prompt ,"Fastboot oem lock"
This gave a confirmation on my device,I confirmed locking.
And after that my device did not booted up.I managed to get in bootloader again as I was not even able to open the recovery and unlocked the bootloader once again by this my device booted up.
I flashed stock recovery and repeated the relocking process,this time I was able to open recovery also but no able to boot up.
I again unlocked the bootloader and installed twrp back turned my device up.
Then I unchecked oem unlocking under developer options.
Relocked the bootloader once again.
And now I am stuck at bootloader,not able to unlock it even this time as I turned off oem unlocking.
Now I can only open bootloader.
Please help!

OEM locking a bootloader on a phone that was rooted is a big mistake.
You'll need to flash stock recovery, then flash the stock ROM via adb sideload.
Can be done with this tool http://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
Thanks for reply

Hello guys, I dont know whats happening with my Nexus 5 right now. Its stuck on Google logo which appears during restarting of the phone.

Please help been stuck on this since past 72hours. Any help to resolve this issue is appreciated. Thanks :crying::crying::crying:
If the bootloader is unlocked, relock the bootloader and reboot into fastboot mode. If the bootloader unlocks itself, the internal memory is probably damaged. If the bootloader remains locked, unlock it and flash 4.4 using fastboot commands.

OEM can be locked and unlocked. But the only problem now is i cannot override the previous partitions as there is an error "failed to write" i dont understand why is this happening this is also the reason i cannot get into my recovery as when i enter recovery it gets stuck for some reason.

Let's start with the bootloader.
Boot into fastboot mode, lock the bootloader, reboot into fastboot mode. Does the bootloader stay "locked" or does it go back to say "unlocked"?

I tried the 1st step by overwriting twrp with cwm dint work. Also ADB isnt connected. I tried to but just fastboot works.
I recommend flashing stock 4.4 using fastboot commands.

I tried flashing new roms it says failure to write to cache,boot,recovery everything fails!
There is no way to erase partitions as it fails!
I would say the internal memory is damaged and will require a motherboard change.
Hey what's up.
Having issues and want to start from scratch but the MSM download tool isn't working for me due to driver issues I can't seem to resolve.
I'm unlocked and rooted with a custom kernel but otherwise totally stock.
Would I be able to just fastboot flash the stock boot.img and relock the bootloader for a total data wipe? Would that be enough to start fresh?
Go into magisk. Click uninstall. Click restore images. Your images should have been backup by the app. Reboot and reset from reset option in phone. No need to relock.
Thanks. Is that as good as the MSM tool as data wipes go? Want to get as fresh as I possibly can without MSM...

Boot to fastboot,

what is the best way to relock the bootloader from Rooted( Magisk) and unlocked bootloader ? I did fastboot lock last time, I guess it locked successfully but refused to boot. Had to use msm to unbrick. Could you suggest best practice for Locking the bootloader again from rooted stock ?

You can't lock the bootloader while rooted. Your patched boot fails startup checks. The only phone i remember that you could root and relock was the oneplus one. There was a software hack to do a soft bootloader lock/unlock without wiping the data.
To expand on that, if you modified any locked partitions and try to relock the bootloader, you'll essentially soft brick. The only thing you can modify is I believe is userdata. If you are unsure, why take the chance, especially since your MSM isn't working.
Just do a factory reset from recovery lol or use fastboot
