Hi all,
Yesterday I tried upgrading my iPhone, which was jailbroken and unlocked, running 1.1.2, to 2.2. To do this, I used Pwnage on my mac, created the modified ipsw, and tried to load it on the phone via iTunes. This didn't work completely, since in the end it hung while it was doing something with the bootloader (instructions said it was supposed to take 5 minutes, I let it stand for about an hour before disconnecting it, sigh). Now if I put it in DFU mode, iTunes sees that there's an iPhone, but if I try to load any firmware on it, it gives an unknown error. I've tried a million things, iLiberty can't find the phone, i downgraded iTunes to 7.5 and tried loading 1.1.4. Nothing, I just keep get the russian Steve Jobs after the pineapple loads up, and iTunes still can't load any ipsw on the phone.
Suggestions?
Thanks,
F.

DO NOT use iLiberty - that is only for fw <= 1.1.4

the Steve image you are seeing on your iphone means that your phone has been pwned and you chose to replace the original apple logo with Steve.

The bootloader process part that hung up on your iphone is Bootneuter in action. It was trying to neuter your baseband bootloader and proceed to the unlock. Since you interrupted that critical part, I hope your baseband BL is OK otherwise you may have a HUGE problem at hand.

What I would do at this point is to put the phone in DFU MODE and do a shift restore using iphone 2G 2.2 firmware. That should wipe everything out.

Once you have done that, you can try pwnagetool again.

I believe you are new at this, therefore my suggestion is to use QuickPwn for Mac. It's easier to use for you. Just make sure you follow the instruction on the screen.

If you want to play it safe, when you are using either pwnagetool or quickpwn, do not select the unlock option. Just select jailbreak/activate the phone. After that, you can manually download bootneuter via Cydia and use it to unlock.

Good luck.
Do not hesitate to ask if you are not sure.

Hi dtube, and thanks for your quick answer.
You're absolutely right on everything, which makes me think that I'm in the "Huge problem at hand" category, since I've been trying to restore it to 2.2, 2.1, even downgraded to iTunes 7.5 to try to restore to 1.1.4, but almost immediately after extracting the ipsw's, iTunes craps out saying that the iPhone can't be restored (23) (in DFU mode it actually says Preparing iPhone for restore, before crapping out, after less than a minute). What alternatives are there?

Restore it using the iphone restore restore mode, not dfu mode... that should work. Just turn on the iphone, and when you see the logo( not before ) keep the home button pressed... After that you should see the itunes with a usb logo.

Then do the restore.

Bummer, same result, hadn't tried that yet though... I tried uploading 2.2, both regular restore and custom (pwnaged).
Other thoughts?

Maybe you are trying to do restore to 1.1.4 firmware and this is not working because you alredy upgraded to 2.2 (i know its not working but it upgraded)...its like doing a downgrade thats why itunes give you the error.

Restore your iphone in restore-mode(not dfu) using the 2.2 firmware(the original from apple).. Use itunes 8.0.2, you still will be able to do jailbreaking, dont worry.
Then use quickpwn to jailbreak.

Nope, I tried uploading 2.2, had tested 1.1.4 two days ago, as one of things to see if it could be done. After that, I realized that I can't revert back to anything below 2.

Humm....
Your are sure you have the phone in DFU mode right ?
When you restore using the original apple firmware (NOT custom firmware ok), what exactly is the error that itunes gave you.

You must use itunes 8.

Yes, I have iTunes 8 installed, and I use a clock to time the 10+10 s to ensure that I'm in DFU.

After extracting, it gives either error 23 or 1600:
The iPhone iPhone could not be restored (23).

When in DFU mode, the iphone screen should be completely black/dark.

- connect iphone to computer
- let itunes detect the phone
- hold power until slider to turn off shows up and keep holding power
- phone will reboot. As soon as it reboots, hold the home button down (now you have both buttons held down)
- count approximately 1 to 6
- let go of power and continue holding home.
- itunes will detect the phone (in DFU mode)

now you can proceed with shift-restore and pick the firmware file
