Can't mount /system rw on magisk 19.4+ #1936

Closed betaxab closed 4 years ago

betaxab commented 4 years ago

I can't mount /system on 19.4+, but 19.3 works well. I tried 19.4, 19.5 20.0, these does not work.

My device: Moto Z2 Force, Stock Android 9.0, PPX29.159-23, I have already removed dm-verity by reinstall magisk zip on magisk manager.

it will show: # mount -o rw,remount /system mount: '/system' not in /proc/mounts cat /proc/mounts

System file can be accessed via:

/sbin/.magisk/mirror/system_root/system

Enable write access like this:

mount -o rw,remount /sbin/.magisk/mirror/system_root

This on a Google Pixel Android 10 and Magisk 20.4 gives me: '/sbin/.magisk/block/system_root' is read-only

Any solutions to that?

same on oneplus, android 10, magisk 20.4:

OnePlus7TPro:/ # mount -o rw,remount /sbin/.magisk/mirror/system_root '/sbin/.magisk/block/system_root' is read-only
