Hola Manuel, que bueno ver alguien que siempre responde. Tengo un Iphone 4. He probado con faith y luego de tener el IPSW Signed, al tratar de cargarlo con el Itune version 12, me arroja el error He revisado el archivo hosts pero no tiene nada de apple. Que puedo hacer? Has probado en otro ordenador, restaurando desde el modo DFU? Lo quise borrar conectando a Itunes, pidio retaurar y de alli quedo colgado en que al pasar la configuracion de idioma y region aparece la imagen de conectar a Itunes.

Investigando consegui que ese error aparentemente es comun luego de la actualizacion a 7. Mas investigacion y me llevo a q lo mejor era 6. Aqui he visto un videotutorial que igual te ayude. Ya me vas contando. Gracias Manuel, pero ese procedimiento ya lo he hecho sin problema. El gran problema, creo yo, es el Itunes, porque cuando voy a esa parte salta el error Hoy voy a tratar en otra computadora a ver.

Agradezco tu ayuda. Normalmente el error se debe a los host. Has probado con otro PC? Hola, Manuel: Te estoy muy agradecido, ya que he podido recuperar mi ipad. Samuel, buenas. Si no das seguido los pasos, lo mejor es que uses un ordenador de otra persona, que no haya usado ni bloqueado los DNS de Apple. Por cierto, ya intente los dos procesos para Mac OS y en ninguno de los dos me aparece gs. Estos errores suelen aparecer cuando tu ordenador no se da comunicado con los servidores de Apple, o bien por tener el archivo Hosts modificado Que no es tu caso o algun programa firewall. Que error te da exactamente?

Crees que puedas ayudarme? Me salvaste la vida!!! Tienes tu dispositivo con Jailbreak? Si no funciona prueba en otro PC. Lo mejor es poner la pantalla rota y ver si das restaurado aunque en ocasiones quefa un brick y no hay nada que hacer. Tengo todo el dia sin telefono porque no queria restaurarlo y no conseguia manera de eliminar ese error, y la solucion que dan en la pagina de apple no funciona.
