So recently I broke my galaxy s4, the screen is broken pretty badly all the way from the glass to the actual display, and is unusable. I really want my s4 back, I was lucky enough to get an early one so I have loki with a custom rom, and I have a whole bunch of files on the internal storage that I want back. So, because the motherboard is still working, I am planning on getting another s4 and swapping the motherboard out. My only concern with this is that there might be different motherboard revisions. So, are there? Are all verizon s4 motherboards compatible in all verizon s4 phones?
