		Para confirmar lo que dicen los colegas..
no hay necesidad de degradar en mi caso lo hice con frp tool de octoplus.
mi version 7.1.2 1 de junio del 2018.
Solo poner en modo download y selccionan el modelo mp260.
La primera vez me aparecio como no soportado.
en el segundo intento funciono bien. si no les funciona al segundo intento solo desconectan y quitan la bateria despues lo vuelven a intentar.
