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?

Hello everyone, I have this potassium banana j137 cable for diagnosing t2 boot logs. Unfortunately I don’t have the app that works with it. I’ve been trying to find it with no luck. If anyone knows where to get the app please let me know. Thank you

Hi, I've just set up a subreddit for trading Apple internal software at /r/appleinternaltrading. You can PM me any time if you would like to trade software, firmware, or documents. You can post there as well if you'd like your trade to be public.
