Yo guys, hope you are having an awesome day!
So the other day I rooted my phone, installed TWRP and installed Lineage OS 18.1 on my Oneplus 6..
The thing is - Now I realize that the Widevine level has been downgrade from L1 to L3 so apps which are crucial to me stopped working.
I have a couple of questions regarding this:
1. I understand that the mere unlocking of the the bootloader killed my drm keys. If that's so, is there an option to Unbrick my phone back to oOS , copy the drm keys (and everything related to widevine) --> Install custom rom and paste all the keys to their respected location thus having the DRM keys of a "locked" bootloader on my custom ROM?
2. Is there an Oneplus 6 Rom, based on android 11, that somehow has access to DRM keys and would give me both the benefit of Android 11 and Widevine leve L1?
3. Is there any way to fix the L3 level on my current rom? an app/module/anything that can take me back from L3 to L1?

thanks!

That will not happen. Stay on locked bootloader and OOS if L1 is a big deal to you.

You simply can't have Widevine L1 on custom ROM's, you should go back to OOS and lock the bootloader again if it's that important to you.
Mine OP7 Pro stayed on Widevine L1 on Lineage OS18.1.

I had followed below steps but first of I had unlocked the bootloader.

"Steps to go enable Widevine L1 on custom ROMs :-
• Flash OOS 11 stable or any build from OB3 and above.
• Flash Magisk and enable Magisk hide.
• Reboot.
• Verify if you have L1 working using app like DRM info.
• Local upgrade OOS 11 stable or any build from OB3 and above (preferably same build).
• Reboot.
• Verify if you have L1 working using app like DRM info.
• Flash custom ROM and you should have L1 there as well."

Different device, different outcome.
Your method sadly won't work on the OP6/T.
