I have tried this method, but it can't be worked,it said can't connected to the device after multistage loaded 。

Pin FFFFFFFF indicates a hardware fault. I do not believe you can fix it.

I have never heard of anyone recovering from the FFFFFFFF PIN

Hardware has gone bad

I had the same thing along with a error that said type S,T,A,R,T, to reset.

That did nothing.

I also got the FFFFFF thing.

Its totally dead now.
