I can't do that. Even entering adb shell is returning an error.Make sure you run the line that goes
mount -orw,remount /system
That should remount /system as read/write.
Code:
[email protected]:~/adt-bundle-linux-x86-20130522/sdk/platform-tools$ ./adb shell
/system/bin/sh: /system/etc/mkshrc[8]: id: not found
[user=1901967]@androi[/user]d:/ $ su
sh: /system/etc/mkshrc[8]: id: not found
[user=1901967]@androi[/user]d:/ # mount -orw,remount /system
sh: mount: not found
127 [user=1901967]@androi[/user]d:/ #
[CODE @android:/ $ su
sh: /system/etc/mkshrc[8]: id: not found[/CODE]
The weirdest thing is at the time the line above appear in the terminal, I have a message on the TV screen saying "Superuser granted to shell", which is confirmed by the Superuser app log.
