Remounting /system fails because it's missing in /proc/mounts about dwarf HOT 7 CLOSED

pls try
in adb.py line 197

if '/system_root' in res:
    self._syspart_name = '/system_root'
    if '/sbin/.magisk/mirror/system_root' in res:
        self._syspart_name = '/sbin/.magisk/mirror/system'
        #self._syspart_name = '/sbin/.magisk/mirror/system_root/system'

or uncomment the 'system_root/system'

from dwarf.

I don't think this will help either, since this is still not my actual system partition I think.

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

from dwarf.

su -c mount

think sysdir should be
'/sbin/.magisk/mirror/system_root/system'

test with latest commit

There has sneaked in an extra / in line 201. I've updated it to

if '/sbin/.magisk/block/system_root' in res:

to actually use the intended path.

But as stated above, manually mounting said path does not work due to the message you see on the screen. See the "#" in front of the command. I was trying to point out I was doing this as root already ;)

Same problem when installing Frida from Dwarf
Nexus 6 - Android 5.0
Console:

failed to mount /system on device

adb.py line 196

res = self._do_adb_command('shell mount | grep system')

Return:

/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,seclabel,relatime,data=ordered 0 0
/sbin/.magisk/block/system /sbin/.magisk/mirror/system ext4 ro,seclabel,relatime,data=ordered 0 0

Next command: (not working)

shell su -c mount -o ro,remount /sbin/.magisk/mirror/system

rm / mv etc... - Read-only file system

from dwarf.

This method works for me on Nexus 5X and Nexus 6

Notebook-home:~ paul$ adb shell

mount -o ro,.. < readonly

working on a fallback

@sn0opy can u try the syspart_fallback branch
set frida path in adb.py line 48 self._frida_path = ''

adding some find / -name frida-server + path via prefs later
