I have a G3 that I have replaced the Digitizer. It worked great for about 2 days then it wouldn't boot. I was getting a grey battery icon that changes to a green charging icon. It wont boot unless its on the charger. I was able to boot in recovery mode and clear the cache, but that didnt work. Then I booted in recovery mode and reset to factory settings, that still didnt work. So I downloaded Kies and went through the Firmware Upgrade and Initialisation, but it still wont boot up. At one point it would get to the Start Select Language screen but as soon as you touched the screen it went back to the grey battery icon then on to the green. Not sure what else to do, any help would be great!
