Hello to everyone who is reading this thread. I am trying to update my old iPhone 2g with 3g 4.0 fw. I used 7-zip to edit the "SupportedProductTypes" key in restore.plist. I changed it from "iPhone1,2" to "iPhone1,1" and now at least I don't get the "not compatible fw" error. But I still get error 3002 after the "apple activation server" process. Any suggestions on how to bypass this process or error?
