Hello All,


I tried to restore my 3g from 3.0 to 2.2 last weekend and i was told by a Apple rep that it cannot be done. So loged on EIC today and i see that there is a way. But I can't get my 3g into restore mode. I was wondering if someone would allow me to call them to get some real tech help. Or call me?


Please I am in crisis.


Eric

Holding down power button plus home button for 10-15 seconds, then releasing power button and continuing to hold home button has worked through every generation of iPhone I can think of.

Might save yourself some phone time by giving that a good few tries, if you haven't done already ...

You have to select the .ipsw file to install. If you downloaded the 2.2 FW .ipsw file, you have to tell iTunes to use that file to restore.

Exactly - and to do that ...

On a Mac, hold down the Option key while clicking Restore, and then select the .ipsw file

On Windows, hold down the Shift key while clicking Restore etc.

Oh, and in that Gizmodo downgrade guide post there were links for .ipsw files for both the V1 iPhone and the iPhone 3G - make sure you downloaded the right one for your phone ...

Your screen should be black when in DFU mode. You shouldn't see any graphic on the screen at all.

There are several suggested fixes for Error 1604 in this thread.

Easiest - so worth trying first - are things like try putting the iPhone on a different USB port or try just double-clicking the .ipsw file with iPhone attached to the PC - but there are quite a few others in that thread as well ...

Why are you restoring to 2.0? Restore to 2.2.1, you will not be able to unlock even after you restore, cause you will keep the 3.0 baseband. No way around it, so...

1 - Open iTunes
2 - Get your iPhone in DFU mode
3 - Select restore iPhone (using the original 2.2.1 firmware, not a custom one), you should not need to do anything but hit the restore button, if you never installed 2.2.1 prior to upgrading to 3.0 it may update first.
4 - Let your 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.
7 - Turn on your iPhone by holding power button for 2 seconds, close quickpwn
8 - Open iTunes and your iPhone is recognized and activated
9 - You can now continue to jailbreak, if you would like.

3.0 is a beta version, did you purchase this phone from someone in the last week? 2.2.1 is the latest version of the software you can get through iTunes.

You're doing fine on all of that - that's all as prescribed for the downgrade from 3.0.

Baseband shouldn't be a worry for you in terms of resolving this issue and getting 2.2.1 running.

Baseband refers to the phone's modem version and the 3.0 upgrade also updated that and that process is not currently reversible - not hugely relevant to you right at this moment unless you need to 'unlock' your phone - meaning make it usable on a non-authorized cellular network (i.e someone other than AT&T in the US). If you don't need to do that, don't worry about that piece for now ...
