I just created a custom ipsw with pwnage tool, let pwnage tool walk me through how to enter dfu mode. I think I had to turn off/on the phone bc it didnt actually tell me to connect to itunes until then.

So itunes saw it in dfu mode, i was then able to select the custom ipsw in itunes and it successfully restored and activated in itunes.

basically, just try to restore with a custom, pwned ipsw

maybe this will help others

PLEASE PAY ATTENTION TO EASY DOWNGRADE FROM 3.0 TO 2.2.1

on a Windows Computer

1) open itunes
2) get iphone in DFU mode
3) select restore iphone (using the original 2.2.1 firmware, not the custom one)
4) let iphone do the restart process until you get ERROR 1013
5) close itunes
6) open quickpwn. you will get a message saying to hold power and home for 15 seconds. do it exactly like that hold the power and home for 15 secs.
7) turn on iphone by holding power button for 2 secs
8) open itunes and BINGO iphone is recognize and activated

there you go...

PS: iphone works fine on FW 2.2.1 and the newer baseband 04.20.01

I believe tools like quickpwn are not supposed to be run in virtualized environment like VMWare fusion and Parallel.

I had tons of problem getting Quickpwn on my Mac to recognize my iPhone as well, after upgrading to 3.0 beta and then downgrading to 2.2.1. In order to re-activate my iPhone, i had to run Quickpwn on my windows-Xp notebook.

So if you are having problem getting quickpwn to see your iphone in Mac OSX, try doing that on a windows-based PC.

I think I love you. It worked on my 3G. The first time I tried it didn't work, I got a 6XXX error (don't remember it exactly) when trying to restore to 2.2.1. QuickPWN then got it booting, but it went back to the 3.0 'you're not a dev' screen. So it never actually installed 2.2.1, the error came up early in the restore process.

So I put the phone into DFU and restored to 3.0 again, then started again with your instructions and it worked. So I guess my tip is if it doesn't work, restore to 3.0 again so you can start the above steps with a fresh 3.0 install.

I'm so happy to have my week old 3G working again. Now the old 2G can go back into storage. I think I'll remain patient and wait for 3.0 to be released. There isn't all that much in it that interests me except for tethering for a holiday I'm going on next month. Oh well...

Tommis

you dont have signal because your phone is not activated.

try my guide from step 6 again.

hope you fix the phone....

PS: i was like that until i did in my guide....trust me it will work!

I am desperate ... Is there a solution that works on mac? because i don't have a PC
I try to do the 6 steps on a mac but it doesn't work... quickpwn don't detect my iphone.
Must I Buy the SDK ?

I have registered my iphone ($99) after bricking it and works now
I can still register another 99 devices If anyone interested I can do that for $9 and we can share the account
