Nokia 6151 V4.11 (no Permite Downgrade), ¿Imposible despersonalizar? Opciones

[downloadman]

Buen dia compañeros, al grano... Nokia 6151, de Movistar España, Lo he liberado perfectamente, la versión del firmware es 4.11 (es la más alta y es sólo de Movistar), pero al intentar despersonalizarlo con un downgrade (no queda más que hacerlo con firmware v4.10), el teléfono no arranca, muerto (intenta arrancar, pero no lo consigue). El log de operaciones dá como satisfactorio el término del flasheo, sin embargo no arranca. Lo he intentado con varios flashes unbrand (despersonalizados), con el mismo resultado, sólo funciona con su propio firm original, es decir, lo vuelvo a flashear con v4.11 y todo perfecto. He seguido los pasos como de costumbre, (garantizo que el downgrade está bien hecho y que todo funciona en orden, fbus, adaptador BB5, box, móvil y pines limpios, programa, pc, etc.), lo he hecho otras veces sin ningún problema, es más, en esta ocasión, lo he intentado ya muchas veces con configuraciones diferentes, como desmarcar TX2, sin marcar downgrade, skip al borrado, e incluso reparar con SX4, sin ningún remedio. Lo más extraño es que de este modelo tengo tres idénticos y a todos les pasa igual. Por favor, ¿alguna solución?. Dejo el log de lectura de teléfono, selftest y análisis de seguridad, por si alguien pueda encontrar un error en dicha información, que desde luego yo no encuentro, saludos...
