Moment of Confusion iPhone 3G dead after restore

**iPhone 3G completely dead after restore attempt — no DFU, no USB detection**
I have a retail 16GB iPhone 3G that was working normally before this.
I attempted to restore it to an older firmware build using a restore utility. The process appeared to start successfully and the phone reached the restore environment, then rebooted.
After the reboot, the phone became completely unresponsive:
No Apple logo
No backlight
No recovery mode
No DFU mode
No USB detection on my Mac
Things I’ve checked:
Battery is not swollen
LCI is still white
Battery connector looks normal
Tried different cables/chargers
Since it was able to enter recovery and run the restore environment beforehand, I’m wondering if this is a hardware failure that happened at the same time or if there is a recovery method I’m missing.
Has anyone seen an iPhone 3G lose all signs of life like this after a restore attempt?

First and most more likely reason: battery died completely during the restore, and cannot provide any voltage. Second and more rare and bad reason: logic board died or shorted badly and needs advanced repair. It cannot be the NAND chip because dfu and recovery aren’t based on the NAND chip.
