The full story:
One of my offsprings used a Galaxy II with Android 2.x and for a reason eluding me the OTA update to Android 4 didn't work. So we brought it to Samsung's customer service centre at Plaza Singapura. Despite the fact that I bought the unit in a shop in Singapore they claimed it to be a 'export unit' and only agreed to attempt an upgrade if I sign that they won't be responsible if they screw it. (So much for global warranty) And they did screw it. The unit powers on but the touch screen is unresponsive. They quoted S$400 to fix it.
I think that the OS upgrade just went wrong and the unit might be salvageable. What can I do?"
