always old k*y d+ again on reborn

[igor39]

as i said i have reborn with firmware 3.12,after d+ change i put new k*ys
but if i turn off reciver or take out cam it goes back to old k*y.
i wondered if the problem was nagra auto swithed on,but when i put nagra auto off,it still goes back to old k*y.
does anyone have a solution for my problem?
thanks
