I have not seen this problem anywhere on the forums. I'm trying to root my g3 that I've had about a week...phone is seemingly flawless with everything else, but for some reason when I try to get into download mode, it will just boot up normally. I press Vol Down, Home, and Power simultaneously and get the Warning screen...it stays there for a second when i release the buttons, then proceeds to boot. At the end of the boot cycle, I see a message that says "Unable to download", otherwise looks normal. I've tried pressing the Vol Up key quickly while the Warning message is displayed, no dice. What gives here? Thanks for any help... By the way, I've also tried a battery pull, and trying to releas the buttons in different combinations...no dice. It just boots.
