and many more but nothing works for me

I am getting below error - None of below commands are working.

For

$adb remount remount of / failed: Permission denied remount failed 

So then I tried with different commands like

$ adb shell mount -o rw,remount /system mount: '/system' not in /proc/mounts  $ adb shell mount -o rw,remount / '/dev/root' is read-only   $ adb shell  mount -o rw,remount -t /dev/block/stl12 system mount: 'system' not in /proc/mounts  $ adb shell "su 0 mount -o rw,remount /system" mount: '/system' not in /proc/mounts  $ adb shell $ su # mount -o rw,remount /system   mount: '/system' not in /proc/mounts 

Answer 1

I had the same issue.The solution is to mount the root (/). After this you can write to /system.

mount -o rw,remount / 

Don't forget to reset the state to 'ro'.

mount -o ro,remount /
