D380f8 Reparacion De Imei Pero Baja Señal. Opciones

[Piloncillo]

Acabo de reparar serie a uno de estos y todo ok.previamente respalde todo por si acaso.
el caso es que me doy cuenta que este quieda con señal muy baja y variable por lo que le restaure la lectura del QCN previamente hecha.El sw pregunta si quieres poner el imei de la lectura o dejar el que tienes obvio le dije dejar el que ya tiene que es el reparado.

Aun asi la señal se comporta igual.
hay otros que tengan este mismo problema?
