Hey mates. I've updated my phone to the Russian KitKat firmware today. First it opened perfectly fine. Then I wanted to switch off to do the wipe cache and wipe data thing. I've pressed the combination volume up + home + power and the screen lighten up but after approximately 5 seconds, the phone switched off. Then I pressed off and it stucked on the Samsung screen. I couldn't switch it off and pulled out the battery. Tried to go into Odin mode, but same thing happened. Then I recharged it to full, but still the same. I can't format the phone, nor open it. Can anybody help me? Thank you very much.
