Mine is totally stock and it was also bricked last night. I tried everything to fix it but it is completely dead. I tried the update last night and didn't interrupt it at all. The progress bar made it to 50%, stalled for a minute and then gave a message that the update failed. It tried to restart and it went completely dead. I've tried using Odin, but nothing happens. sin
I also called AT&T and was initially less than pleased after I was told to call Samsung for a possible fix. I told CS that I didn't buy the phone from Samsung and that I wasn't calling them, since it was an AT&T problem. I finally got someone to authorize a return and my new one should be here in a couple of days, but the fact that this thing was totally bricked so easily because of an official update is ridiculous.
