[OnePlus 3 Questions & Answers] madm03:
Hi, i now that everyone seems to be able to use magisk under oreo, but i can't get it to work since the first oxygenos oreo beta release.

the funny thing is, it seems to install correctly, but after the reboot there is no magisk manager, and no root functionality.

What i tried:

* Dirty and Clean flashed every beta and stable build.

* Tried the last 4 magisk releases, last version 15.3

* Supersu, wich works every time

* TWRP 3.2.1 blu spark 8.61

I deleted everything except /data/media/0/*

Also, a log file from a magisk install after a clean flash:
