Cannot downgrade iphone 3.1.2 to 1.1.4
I have been trying to downgrade my 1st generation iphone from 3.1.2 to 1.1.4 (wireless not working issues). However, when i put the iphone in the dfu mode and connect to itunes 7.2.6 or 8.0 or 8.2 i keep getting the error "the ipod software update server could not be contacted"
I have tried all the suggestions posted on the internet including modifying hosts file but it seems apple has blocked the old versions of itunes from contacting its server when it discovers an iphone in dfu mode. When i connect the iphone in dfu mode to a new version of itunes it recognizes the phone in dfu mode.
Any help in bypassing this issue to be able to restore iphone to 1.1.4 would be greatly appreciated.
