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.

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.
Fully stock, locked bootloader.
Wiped everything and went back to stable builds and locked to get rid of dm-verity.
After kernel sources released and Fransisco updating I'd like to flash it... So unlock bootloader flash boot and re-lock?
I don't want to lose data and I don't want the dm-verity flag to trigger
Thanks in advanced compadres
If you locked the bootloader, there's no way to unlock it again without re-wiping data. Also, don't re-lock the bootloader with any modifications, or you risk bricking your device.
There is no reason whatsoever to re-lock the bootloader on OP3. Ever.
So if you want to go custom again, backup your data, unlock bootloader, flash anything you want, restore data. And don't touch bootloader any more ...
About dm-verity: it took a while for someone to find a good solution, but now we have it: boot to fastboot and type "fastboot oem enable_dm_verity". Simple as that.

don't ever relock BL unless you're on stock ROM & Recovery.
you can disable DM verity flag as said above:
boot to fastboot and type "fastboot oem enable_dm_verity"
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.
So i get this idea i don't even know where. So first step is to get root access. Like kingoroot that can done this on device without bootloader unlock. Than i'd use TWRP app to flash recovery and lastly flash a custom os. I really dont know if it will work but i will definitely try this sometimes
Or just flash factory firmware without needing root or the bootloader unlocked...
Hello
I've installed lineage 17.1, my recovery is TWRP 3.4.0, I also installed Magisk.
Every time I restart my Phone I'll get a warning screen that my bootloader is unlocked.
My question is: is it better to lock the bootloader again or let it unlocked?
If I lock bootloader, can I still update lineage en will I keep root from magisk?
Do I loose data?
You need to have an unlocked bootloader to use Custom ROM like Lineage OS with root by Magisk.

It is dangerous to lock the bootloader while having a custom ROM. You will lose the ability to flash zip files if something goes amiss. In addition, while locking the bootloader, you will lose all data.
If you are on OOS, then you can safely lock the bootloader.
Locking of bootloader will not affect the custom ROM already installed or root.
