iPhone Bricked/Push! Need help from experts!

[AmBull]

Hi There! T.i.a for viewing this!

I have a very uncommon and strange problem with my iPhone 3G.
I have tried almost anything to fix this with no succes

I managed to have my 3G working @ 4.2.1 (custom, hacktivated) with modem 06.15.00 (see history below)
But iTunes still can't see my iPhone and Push is not working i would like to fix these things!
Since i installed openiboot it might messed up my (boot) files..

But the most strange thing i just discovered is that under general->info->
My model number is shown as N/A and my serialnumber is blanc! even google shows no hits on this

History;

I had my 3G on FW 3.1.3 and went to 3.1.2 for openiboot to jailbreak my PS3. (sep/2010)
Somethings went wrong and i couldn't even go into DFU or Recovery mode to set things straight. (maybe i could have but didn't gained the knowledge at that time)
Finally i was fed up with a non working phone and i updated to 4.1 (officially)

Then the trouble begon, i couldn't even restore offically (4.1) iTunes said

We're sorry, the iphone you connected may be damaged and cannot be activated for service. We recommend you visit your nearest Apple store for more information.

I coudn't restore to 4.0/4.0.1 & 4.1 same error.
I only could go back to 3.1.2 but because of my updated baseband i had no network.

I have tried:
Restore to 3.1.2/3.1.3 - 4.0/4.0.1/4.1
on fw 3.x no signal-
on fw 4.x "there's a problem with your iPhone"
at that time i had 05.14.02 BB and 06.04 Bootloader

You should always be able to go into DFU mode. Just use redsn0w like normal.
