I have been trying to downgrade my ipod touch 3g (32 gig) from 3.1.3 to 3.1.2. I know that apple stopped signing 3.1.2 I was previously jailbroken on 3.1.2 and I did click the red "make my life easier" button on cydia. I also saw the green message that said my device has that shsh thing. I edited that host file so that apple checks with saurik's servers. I entered dfu mode (yes, the real dfu mode, not restore mode) I shift-clicked the restore button and browsed for the 3.1.2 file. I'm still getting the "device not eligible for requested build" error. What am I doing wrong?
