Dear all.
I am aware I am going to créate a new issue really difficult to solve.
From the beginning, my F C B doesn't save the changes I edit. When I switch OFF / ON the device, all the edited parameters are missing and they've backed to the default factory values.
I was working with original EPROM V2.2 but I replaced it for EPROM UnO_4_KEMPER (V1.2, the last one) and the problem keeps.
Can anybody help me? perhaps changing any electronic component.... I don't know.
