Update iPhone 3G to 4.0

[Impulse29]

Here's the situation: I have an iPhone 3G that is jailbroken at 3.1.2 and I would like to get it to 4.0. The iPhone's power button is broken, so I'm unable to get it into DFU mode. I've made a custom ipsw file to get it to 4.0 using pwnagetool (because the dev team say that it can be used in recovery OR DFU mode). But when I put it in recovery mode and update with iTunes, it gives me a 1604 error.

Any suggestions? I haven't tried using 4.0.1 yet...

Oh, and I'm using os x 10.6.4 w/ iTunes 9.2 ...

Time to get a new phone or get it repaired (likely more expensive than new/used 3GS)

You will never be able to put it in DFU mode without the use of the power button.
Have it repaired or replaced.

You can put it in and take it out of recovery mode using RecBoot.

According to OP, he can get into recovery, it's DFU that is the problem.
