Lenovo S6000h does not allow firmware update

Question

Has anyone had the same problem? When you go into settings and select system update the tablet tries to open the screen but all you get is 'Unknown Error' message. I tried to repeat the steps multiple tiimes and always with the same results. The system has not been rooted, so that cannot be the case. I am trying to solve my original problem which is that video calls with Skype or with Hangouts are not working at all and was hoping that a FW update would do the trick.

Found the answer..here is what is needed to do
SwingUtilities has a method invokeLater() which takes a Runnable object as a parameter.
What this will do is immidiately returns when an action is triggered hence creating another thread for the method you want to start separately so that you can update your GUI while the other mehtod is being processed.
Below is the code snippet
Runnable tRunnable = new Runnable(){
                public void run(){
                    methodThatNeedsAdelayedRun();
           SwingUtilities.invokeLater(tRunnable);Hope it helps yo all who need it..:-)
