Is your Widevine L1, out of curiosity?Can't believe how smooth it went, it took me like 3 hrs because i had to do back ups and update OOS and then restore my VoLTE settings before jumping to the rom .
But im so glad i did, this is impressive, i was indeed able to close the bootloader and then just sideloaded magisk and its fully working.
Now i was hoping for the warning screen on boot to dissapear but at least it changed to somthing else xd
I used OOS 18.104.22.168 as base on both slots
Rom even comes with dolby port , thats a plus for me.
