I have very same problem with 3gs. NOT POWERING AND NO CONNECT TO COMPUTER.
I have changed the battery but that wasn’t helpful, then I put original battery back and phone back to life. After that I have switched off and phone wont torn on again.
The iPhone doesn’t do to DFU mode.

For me, I measured the battery level and it have the same level with the good one. So decided not to replace this battery.

The phone is hanging now. When connect to USB to PC, it will not detect. You cannot go in to DFU mode.

For solution, easiest way is to wait for battery to go Flat COMPLETELY.
Otherwise, remove battery and resolder back.
Plug USB cable into phone and it will go into Recovery mode. PC will be able to detect the phone again.

Hey, friend! Why you have wait or do like that?

Good Solution is :

Press Home button & Power button until it turn off and then start again.
