how to back original ESN of phone?

[youmax]

Hola, Lamentablemente he sobreescribido un 5165, con un ESN de otro, la verdad no se como volverlo al original, si alguien sabe, por favor avisenme!!!!!! (NO TENGO BACKUP DE LA EEPROM VIEJA)
Es raro, con el soft NOKIASOC2 figura un ESN y cuando entro con la programación #0#*SEND me aparece el ESN original del telefono!!!!!!!!
ALGUIEN SABE EN QUE LUGAR DEL ARCHIVO BIN de 16kb de la EEPROM esta el ESN o como CAMBIARLO????????, tambien me gustaria saber hasta donde se puede sobreescribir la EEPROM (en lineas) sin cambiar el ESN........... ESPERO QUE TENGA SOLUCION!!!
Gracias.

change it in the box that says esn. Use the esn from the back of the phone. The hex of the esn is also in the eeprom. Use a hex editor and search for it.
