1. Try to reflash only the rom. Also delete the Android folder in internal storage (sometimes can cause bootloops idk why). I have the FN variant and the rom is working just fine.

2. Check if you are using the latest magisk

3. Check if you are using the arm gapps for Android 9 (use pico or aroma to choice what you want from gapps)

Hey

First of all thank you for this awesome rom. It's literally perfect for me. There's just one thing that I can't seemto figure out. How do you use the SD card as internal? I have this 124gb sd card. And I've searched for hours and I cant seem to convert it to adoptable storage. I have tons of apps i wnna transfer. So any tips? again Thank you.
