How to lock OEM on OnePlus 6T McLaren

[KomodoPlus]

Hello Team,

I have rooted my phone (OP 6T McLaren) and wants to re-lock the OEM.

How did I root it?

Tools used to root the phone - TWRP (twrp-3.2.3-2-fajita), Magisk (v20.1) and fastboot

Current Details
Oxygen OS Version - 9.0.17

So the question is - Can I lock OEM with TWRP and Magisk on the phone? If not, how and would much appreciate if someone can put me in the right direction please?

Reflash your rom through local upgrade to get rid of twrp & root..
And then proceed to relock the bootloader via fastboot
Relocking the bootloader will wipe everything on your phone..

Locking your bootloader with TWRP and Magisk will result as a brick i thing, it's not adviced to do so. Only relock when everything is stock
