Confused....

About the so called 1.03 firmware... They told me that if i already have the 1.02 beta, and it did not work. I needed to rma my controller. Because the 1.03 could brick my controller. I'm really confused now. Ive read stories about people who returned their raiju ultimate controller 6 times, and still had the same issues. Why did they even wanted us to test the beta, if we would have to rma it eventually ? I'm so confused right now. What to do ????
