I never upgrade my phone before. But today I decided to upgrade firmware through the Kies but its end awfully. Kies succesfully downloaded update but when it starts to download the new firmware to the phone its stood on 1%. On the screen of the device I saw Android logo and under it "Do not turn off target". But after waiting 2 hours it was still on 1%. Then I canceled the download and disconected device from CPU. And now I can't turn on my device, its keeps showing "Device and computer picture with attention icon in the middle of them". I removed battery and put it back, but when I am turning on device it shows the same picture of "Device-----Attention icon-----Computer". The phone in 1 year warranty and I give it to the service centre already, but I am still worry. What do you think can the guys from the service centre repair the phone or not?
