Sos!! rootear mi star b92m

hola a todos los foreros...
a ver si me podéis ayudar con mi dual sim b92m, de 1gb y con 4.1.2 de android, he intentado rootearlo, pero me es imposible.
Pongo el movil en depuración usb , y la opción de permitir instalación de aplicaciones de origen desconocido.
El ordenador me lo pilla, y al iniciar el root, sigue todos los pasos, se reinicia dos veces pero me pone este mensaje.. a ver si alguno de vosotros me podéis ayudar.. muchas gracias:
Device type:
1) New Standard-Root (thx Ariel Berkman)
2) New Xperia Root by Goroh_kun (Xperia Z, Xperia V [JellyBean] ...)
3) Old
4) Old-Special (for example: Sony Tablet S, Medion Lifetab)
G) Google Glass Mode (thx Saurik for the ab file)

x) Unroot
