I am getting the same error too, when trying to restore with iTunes; I tried it 2X, Version: 3.1.2, Modem Firmware: 04.26.08, iTunes 10 tried to see if there is way around this not much luck & I don't know if iTunes 10 is the reason its not working, but I would like to update to 4.0.1

1) you guys need to add a part where you edit c:\windows\system32\drivers\etc\hosts to add the line "". This way the check of the firmware goes to a cydia site and thus won't fail. 2) it's possible to downgrade from 4.0.2 to 4.0.1 and jailbrake with Redsn0w and unlock via Ultrasn0w.

So Yesterday I attempted to jailbreak my 3G 3.1.3 05.12.01 Using this Tutorial and it didn't work when i tried using the 4.0.1 (3G): iPhone1,2_4.0.1_8A306_Restore.ipsw (after trying to check with Apples server it gave me an error, something that this update cannot be used .. or something)...Then i tried the other 4.0 ispw.. and the whole procedure went thru .. DFU moed and all but when iPhone rebooted it was just the same as it was earlier .. same version etc) Can u guys plz help me... How do I upgrade to the iOS4 and also have it jailbroken ..

If u can guide me to a tutorial or sumthing that wud be great :) I have upgraded to the latest iTunes 10 Thanks in advance for any help.

Apple doesn't accept anything less than 4.1 right now... which can only remain your iPhone dumb for some time before the jailbreak comes out. So, what you have to do is to wait and constantly check the iPhone Tutorial on this site. Very soon it will be released. Hope this helps!

Thanks for yr response... OK What I have done is Updated to 4.1 than using the Beta Release of Redsnow for Mac .. I did the jailbreak .. But I dont like how many things crash and also it gone a bit slow... So I want to go back to 3.1.3 or 3.1.2 Basically anything other than 4... Can u guys plz help? Thanks!

Sorry, don't think you can even do that (downgrading) except if you previously saved your SHSH Blobs on saurik server before upgrading to iOS 4.1 which I am pretty sure you DID NOT!
K - September 30, 2010 at 9:46pm
Hi.. Yes I think I have saved them.. Coz I remember.. Once when I opened Cydia it showed a msg saying something like "yes make my life easier.." and I did select it.. So I believe I have done that.. So how do I go about it.. Emmanuel I appreciate u following up on this :-) Thanks!
K - October 1, 2010 at 2:38pm
Thanks Emmanuel... Is there any way I can confirm if the SHSH blobs were successfully saved? Using Cydia? or sum other method?
Emmanuel - October 1, 2010 at 7:43pm
I don't think there is any other way to figure that out right now since you have already upgraded to 4.1. So, just follow the instructions on the links, maybe Cydia successfully saved them for you. Good luck :-) !
