Hi, I have a problem rooting my OnePlus 9 pro with Bliss Rom 15.7. I've followed the guide using the C61 version (because this is the firmware version that I used to flash the rom), but after "fastboot boot magisk_boot.img" my phone turned black and then stuck on Android logo. I've solved this problem flashing again the boot.img from the bliss rom but I obviously don't have root. Does anyone know how to solve? Thanks in advance.
