My problem seems very similar to the one discussed here:

I've already tried everything suggested in that thread, and none of it helped.
As of two days ago, my phone will not start, and I am unable to restore the firmware. The phone is a 3G running pwned 2.1 firmware.
The phone got very hot, and the battery quickly drained. At about 50%, I restarted it, but it didn't help. At 20%, I plugged it in. The battery started draining slower, but it was still draining. Now the battery is completely dead as far as I can tell; the phone only 'works' while connected to USB.
I booted it into recovery mode, and iTunes detected it. When I tried to restore the firmware (I tried vanilla and pwned 2.1, 2.2, and 2.2.1), the phone would shut off while iTunes said 'preparing iphone for restore', and then about 2 or 3 minutes after the phone shut off, iTunes would give me a 1604 error.
I then tried it from DFU mode. When I started a restore, the phone screen would light up white (from the off that is DFU mode). If I tried any firmware other than 2.1, the screen would stay white and I would get an error 23. With 2.1, the same thing that happened in recovery mode would happen.
I have also downloaded iRecovery, though I don't really understand what it does. I've been unable to find instructions for it anywhere. It detects my phone (though only in recovery mode, not DFU). I can change the background color, and I can load files into memory. I'm not sure how to use it to do anything useful.
Ideally, I would like to get my phone working again. However, if I can't, I want to somehow get the default boot logo and recovery image onto the phone so that I can return it.
I'm not sure if it will help, but here is the output from printenv in iRecovery:
