Cannot open /data folder in a rooted Android device

Question

My HTC Sensation is rooted (I can see the SuperUser app; I can su using the Terminal Emulator app; I was able to install Android Stock ROM Cyanogenmod).

I'm not able to open the /data folder using either ADT or adb shell su (permission denied) or File Expert app.

What can I do to open the folder?

Answer 1

I found the answer and solution:

1. As for access the adb shell, I need to enable "Root access" for ADB in "Developer options" (this apply for stock Android 4.0.4 by Cyanogenmod but the same option could be present somewhere else in your phone)
2. As for File Expert, the "Root Explorer" functionality is only available in their paid version
   • I'm going to use ES File Explorer and the likes
3. I haven't found a solution for access through ADT's Device Manager yet but I'm happy having 2 options above

Answer 2

If you have installed supersu like apk. When you do 'su' in the shell, there might be a notification on screen asking that if you agree the program to run 'su'.

You have to grant the permission.

Answer 3

Nothing if your mobile is root then u can't access anything without the SU permission just take the permission by @kiNGUSER (app) then u can give access to your file manager
