Same issue here on both Roms and I have the same phone. Currently on Crdroid 7.6 since the Sim works. Hopefully it will be fixed soon.
Woah woah woah. I wasn't trying to seem ungrateful or anything. Out of all the OnePlus 8 roms, I like this one the most. I absolutely appreciate all the effort your putting in to figure out our issues. I apologize if it came off in any other way.
It can't decrypt. You are correct on that, but this ROM on this phone comes decrypted out of the box so TWRP does work. And there is a separate recovery partition so you don't have to worry about magisk being deleted by TWRP when you flash it. If you want to be double sure, flash DFE zip after magisk and TWRPYeah, but I have read that TWRP doesn't work with Android 12 yet. So coming from OOS11, installing TWRP, installing derpfest and booting initially up to derpfest doesn't remove TWRP I once installed? Will I be able to boot into TWRP again after first initi Boot in order to install magisk?
