Hi guys, I just help my mom upgrade to an iPhone 4s. The guy who sold it to me did not restore it. I want to clean restore, re-jailbreak. However when i try to restore the 5.1.1 in dfu, i get error 16xx. Then I realized that hosts. I then went into my tiny umbrella and uncheck the " set host to cydia" After I get the error "this iphone iPhone is not eligible for the requested build. I checked and double checked that is the right ispw. I also went into cydia, and I do have the shsh 5.1.1 saved in my cydia. I tried everything, but still can't get it to work. Any cluses? Thanks SIDENOTES: - OSX 10.7.4 - itunes 10.7 - Phone on 5.1.1 - my host files already have # marks in front of the apple ones. Thanks in advance!!!
