Same here. Did you ever get your device working again?

The suction cup worked too well in my case. The display assembly popped right out and a ribbon cable appeared to come completely disconnected from the home button. I proceeded with the rest of the battery replacement and think it all went as it should have, but now my device doesn't indicate that it's receiving a charge when plugged in, and no combination of pushing or holding the home and sleep/wake buttons does anything. My phone was well on its way to brick status, but this one slip-up seemed to secure it.
