How to Relock Bootloader of OnePlus 7t

[Lossyx]

Got my HD1905, unlocked bootloader (no root etc. Only to be able to use TWRP, just in case) and installed my apps. Then I noticed the Netflix problem with unlocked bootloader. If I do a 'fastboot oem lock' now, I'm pretty sure it will do a factory reset, correct?

Thx, W

You need to flash stock again, including recovery, then lock the boootloader.
(And twrp is not functional right now)

Thanks lot, but I thinks it's a misunderstanding. I only unlocked bootloader and installed 'standard' apps, no TWRP, root, magsik,...
Then I don't need to reinstall stock ROM before 'oem lock', right? But I assume, that the phone will be reset to factory when I execute the 'oem lock'..?

Should be able to, assuming you haven't done any modifications, yes.
Relocking the boootloader just wipes internal storage, and does not reset the software to stock, which is why it's important to be 100% stock before locking it.
