I tried flashing that MP on my phone with RSD Lite. It came to a point where it said to manually turn off the phone and just got stuck there. So I disconnected the phone and now it doesn't even turn on, its just black and when I connect it to the PC, RSD Lite does not detect it and my PC says: USB Device not Recognized.
I tried that force boot thing, I took the battery out and pressed * + # and put the battery in. But it still doesn't boot.
