Next time SEARCH before you post you idiot And a good option for not UPDATING baseband USE sn0wbreeze 2.9.5 and preserve baseband and you will get a firmware in desktop then PWNed DFU mode.... Restore with it.... then youre baseband will be preserved not updated it will be the same as you restore what you have
