this really doesnt work.. I can tell you what happens step by step..

I watched your video and somehow your itunes verifies your firmware (yes I have edited the hosts file in \system32\drivers\etc) mine doesnt!!

Lets carry on, i did step 1 twice and got the same message both times "not eligible..." then continued with your steps and nothing happened still on 3.1.3.. if you want a more detailed description or if you can help me more, MSN: yigitcan_guler@hotmail.com , MAIL: yigitcanguler@gmail.com

Thank you

Then you're doing something wrong. I tried a couple of times adding the apple IP thing in notepad and at last it worked. But I dont get error 1015 I get error 14. And RedSn0w won't recognize the 3.1.2 firmware. Så it doesn't work for me either

I have tried and tried and can't get this to work. when running notepad as admin and pasting the extra and click save it doesnt automatically save it goes to save as instead. so just keep getting not eligable when tring to restore with the 3.1.2 firmware. there must be some way round about this if u seem to be able to do it

downloaded all the programmes done word for word but unable to downgrade the firmware ( not eligable) does this only work for 3gs phones that had 3.1.2 frimware on it previously, does it work with new un-jailbroken phones????

You must have broken your iPhone earlier, so you need to have your SHSH files on Saurik's server.

I tried to restore the 3.1.2 firmware as instructed, but it just kept saying 'isn't eligible'. I am sure /etc/hosts already got updated. Mine is a brand new 3GS (MC model)...does this procedure actually work for the new 3GS?
