Wait, I'm having this issue. After installing a Magisk module, my phone boot looped and I had to flash the firmware, and now the baseband and IMEI are gone and it randomly boot loops. I'm trying this guide now, but let me know if there's another solution.

Update: This guide fixed the issue. Now my phone works perfectly now :)
