Hey, I just decided to jailbreak for the 84729382th time. So I create the .ipsw, connect my phone to iTunes, and do the option-Restore thing and choose the right thing. Then, iTunes says it's "Preparing iPhone for restore." So I'm browsing MR while that's happening. Suddenly, my iTunes icon starts bouncing in the dock. Then, I read the message: "The iPhone "iPhone" could not be restored. An unknown error occurred (1604)." So I click the More Information button, and it opens a page in Safari that gives some tips. I then updated iTunes to 8.2.1 and tried again. Nope. Restarted and tried again. Nope. So, anyone know why this is happening? Long story short, my phone won't restore to a jailbreak .ipsw and gives error 1604. Thanks a lot in advance for any help!
