I used this one https://forum.xda-developers.com/t/rom-official-fajita-12-lineageos-19.4437349/page-7#post-86857977Which .zip did you use, did it fix safetynet and do you need to do the installation every time, when you update to a new build?
Edit: I didn't extracted a fingerprint on OxygenOS. Could I still do it on LineageOS or is there a need, if I just use the PowerShell script?
But u have to execute also this "adb enable-verity" at the end. Without this u will get a bootloop after updating nightlies.
