My phone was ZiPhoned or completly screwed. I did not hear a concrete solution to fix the iPhone. Not even iLiberty or Pwnage could fix it.

I read that if you replace the com board, it will fix the problem. I bought the board and now I am ready to replace it but before doing anything, what is next?
After replacing the board, in what state the phone will be?

What software should I use to bring it back and unlocked?

Did anyone replaced this board yet?

The board was bought from: www.ifixit.com

Just change the commboard,

recover to 1.1.4

unlock it with the method of your choice. (iplus, pwnage,....)

enjoy your working phone.

PS. take extra care when unpluging the RF cables (white ones) from old comm board.

"just change the commboard" is very vague...

Ow, and you're gonna have to unsolder the battery, watch out, if the red cable touches one of the others or the phone the battery might explode.

White cables are ok, the worst is replugging the four connectors under the main board when you have the battery connected, so solder the battery once evth is connected, then white ones.

Thank you guys, I hope I will manage to replace the board, I have the tools and desire for the fine work, so I'm OK with that.
The guide is here: http://www.ifixit.com/Guide/iPhone/C...s-Board/105/8/

I am more interested in what software or procedure to use after replacing the board to not screw it again. Thanks crackn! Hopefully it will work.

I said that because if you dont know exactly how to do that, its better to not try.

seems that DigitALL knows how to do it, his doubt is about software as I understand.

PS. dont need to remove the system board.

1. remove the back cover.
2. remove the white cables with care (RF)
3. remove the 2 screws.
4. remove the commboard with battery.
5. unsolder the battery starting from the red wire, white wire and last black wire.
6. solder the battery on the new commboard starting from black wire, white wire and last red wire. (reverse order)
7. fit the battery in place and connect the commboard back. (dont worry, you can connect the commboard with battery already soldered.) if you aren't secure about your solder skills, let the phone discharge complete before do that.
8. put back the 2 screws.
9. put back the RF cables.
10. put back the back cover.
11. follow the procedures i told before to restore to 1.1.4 and unlock.

12. enjoy


I hope now its clearer to understand how to do that.

cheers,

the software part is easy. just recover to 1.1.4 and unlock with prefered method.

ok i understand but the offer is there if you want it

I think you should do the red one first, cause once it's soldered if the other ones touch the phone it's not gonna cause any shortcut, in the worst case it might boot the phone. But i never tried messing with them so maybe different people have different versions...

Guys, I don't understand something...
I still did not open the phone yet. I need to be relaxed and find time to do it.
Looking in the pictures from the guide I provided in my previous link and based on the operations enumerated by crackn, I wish to ask, why do have to remove the battery and the logic board? It appears the com board could extracted by removing the two white coax cables, two screws and then pull the board out.
On the bottom it has one black connector but it comes out by extracting it.

Why do you need to remove the battery and take the whole thing apart from the display?
------------------------------------------

Yes, my big wonder is about software and what procedure to use to ensure it will go smooth.

I changed the board... Man! It took me about four hours but I worked very carefully and I was successful. You need very good and fine tools and lots of patience.
I haven't closed the phone yet, to make sure it works. I have plugged it in, restored with with iTunes to their 1.1.4 and now I have the screen:
"Welcome to your New iPhone"
"Activate you iPhone with AT&T"
"Register with iTunes... bla bla"

What do I do next? Is it ready to unlock it? What application is best to use? (pls do not say ZiPhone...)
Is iPlus good?
Or is it better to use a Stealth SIM hack? I am kind of afraid now to use software hack since all this trouble started with ZiPhone.
Please help me out. I will come back with details.
