read only filesystem

mtkeasysulog.txt LG Q7 android 8.1 Badly need root access to change some system prefs and remove bloatware. No other install root options for that device. Pls help if you can. Thanks.

[Sergei-Alekseev]

Still the same in latest version.

type these commands in sequence in your terminal, to mount the /system as rw

su -c killall system_server #hot restart, to bypass the verification that prevents remount the /system
su -c mount -o rw,remount /system #mount /system as read write

[Sergei-Alekseev]

What? "su -c"? Its impossible because no root on the phone.

[Sergei-Alekseev]

ok. what to do now?
