Real factory reset iPhone 3g

[KuaKercL]

Hi people, first poster here. I'm having troubles trying to giving sound to my iPhone 3g, I know is not a hardware problem because I put another mainboard and work just fine (i'm just hoping that's not a problem in the mainboard) so I tried to restore from the phone with the "Restore all content & settings" and with the restore from itunes in DFU mode but nothing seems to leave it in the proper "right from the box" state.

Any help will been thankful.

If you did a DFU restore and didnt restore from backup on itunes then theres nothing much you can do.
And congrats on the miners rescue

Thanks guys, but I did that hard reset and the iPhone doesn't have audio still. Any other ideas?

Nothing else you can do, its pretty much a hardware issue IMO.

OMG this is getting worse, when I restore from: "Erase All Content And Settings". Reboots and get the apple logo loop of hell.
