Need a bit of help here.
I just dirty flashed Beta 5 on my 7 pro and I got stuck on a bootloop. Firstly, I installed the latest TWRP by mauronofrio. Then I flashed PA, the TWRP installer and magisk on both slots. After rebooting, I got into a bootloop. Back to TWRP, I realized it was
unable to mount data (my phone is decrypted, by the way). I'm not sure what to do now. Anyone got any ideas? Much appreciated
Your problem is that you flashed Magisk twice.
This is how I flash most ROM's and literally never have problems.
Flash rom(from USB)/
Flash TWRP(if not included in rom zip)/
Flash Gapps(if not included in rom zip)/
Reboot to system/
Repeat (with different rom)/
It's this way on my ph-1 essential phone (Mata) It's this way on my OnePlus 6t (Fajita) it's this way on my OnePlus 7pro (Guacamole)
Just do it like that and you'll be good always!
Good luck and I hope this simplifies it for you.
