Samsung Galaxy S3 won't turn on.
Hi. I was reading the thread about the phone staying on the "Samsung" icon because after having activated my phone with Sprint, I had an update made and and it wouldn't go past that screen. I did the reboot where you press the power,home and volume up buttons and it went back to the same thing. After reading this, I did the download mode and took off the battery so I could do the Kies thing, but after that, it just doesn't even turn on anymor, it just vibrates. I would really appreciate any help with this matter.
