Recently there was exactly the same problem as you.
On my Redmi 6 miuipro, after one reboot, it can show that the Magisk is not installed, and after the second reboot everything is fixed - everything is normal - and the module and magisk. Maybe you do the same. I sin on the wrong command to restart, or something with boot / recovery, since there is no separate recovery itself, it is sewn into the boot. img.Post has been editedPalychRv - 19.04.19, 21:34
