Internal storage is damaged, I don't know what to do?

"hi

you must change internal storage(Hard)."

"Service centers of Huawei do not give service to mobiles, they just offer replacement boards at a high price almost the half of the price of a new mobile plus replacement work !

It seems that the integrated circuit called ¨power management module¨¨ that manage power and battery charge fails.

Try particular technical service, they do what huawei service centers do not."
