Hi, it has two difficulties. In the first, for placing, the MB must have the same size and shape (for frames). In the second, the connections on the PCB (the board) have to be the same in the same places (for conduct the electricity between components, including a battery or a loudspeaker).
Usually, the PCB is compatible if one has two sim slots instead one on another board (different models but one the motherboard). You can meet it at Nokia or Samsung for LeEco I don't know, better to say I have doubts.
I've got one with bad GSM performance. My guess was that the antenna is not connected properly, so... thanks but I think I'll use it as an ebook reader or something :-D
