SuperUser doesn't give/prompt root access I was trying to move GoogleMaps on SD-Cards using Link2SD.
When I tried to do so I got a message stating


  Link2SD could not obtain root access.
  if you have root access make sure you respond 'Allow' or 'Grant' to the superuser request


Then I opened SuperUser to check the application list. I was surprised to see that there were no apps there! The last time I have checked there were some apps there(Link2SD, BatteryDoctor, TerminalEmulator).

Searching through the net I read that if an app needs root access, it will ask for it. The next step was to see, SuperUser's settings/preferences.


The Automatic Response is set to Prompt
Notifications are ticked
Notification Type is set to Status Bar
Use Advanced Prompt isn't checked


Navigating through Link2SD, I've noticed that Link2SD was updated. The next thing to do was to uninstall it and install it again. The first time I run it, it never prompted me to give it root access.

What may be wrong? Is there a way to give apps root access(by "brutal force")?
Download Root Checker and see if phone is still rooted. If it isn't rooted anymore, re-root your phone.
