So basically, I tried root my phone and it didn't work. My phone just feezes on the first Samsung screen when I turn it on. I decided to Google it and found some stuff telling me to reflash my phone with this software and that software and I've tried most things. The best thing I get it an exclamation mark next to another phone after flashing with different firmware. I'm getting pretty desperate now. ;[ Anyone any ideas on what might fix this?
