I have a question, the screen doesn't work. It appears like it doesn't. I looked at the display and it's not damaged at all. I recently downgraded my Samsung from 4.1.2. to 4.0.4. I request Vincom to answer as I have fallen into deeply desperation because my s2 is not working. It's only a week old and I've downgraded it to 4.0.4. because the old owner told me it used to work better with that version. I think he "trolled me" (like you people say this days...). Any way to make it respond again? Forgive me if it's hard to understand what I am trying to say. As you can see, I am from Germany (a part used to be known as Barmen, Kingdom of Prussia.)
