How to Clone a Qviart Mini.

Hello, I have been testing with this receiver.
I have read the 25Q64FVSIG memory contents with a minipro programmer and then I have programmed a new memory with this dump. I have placed that memory in the receiver but it does not work. Show this error "sw is wrong please download again 2". Why?

Another test I have done has been to swap the chips 25q64 of 2 receivers between them and they do not work. Shows the error "sw is wrong please download again 6".

I do not understand why, can anyone explain it to me?

I have read the datasheet of w25q64fvsig memory and I have seen that each device has a "unique ID" of 64bit. And perhaps this is used as a protection mechanism that prevents it from being cloned.

In addition the microprocessor must also have another ID and does not work when the memories are exchanged in 2 receivers.
