Why is the 1st Gen iPad being shown in a 5th Gen tear down? Is it exactly the same minus the Touch ID home button?

I saw the sleeves on these.. and when looking at the replacement display saw they matched exactly and took the chance it was intentional. The only thing that got me.. was the bottom panel screws.. didn't know there were 3 types.. (should have known though, I mean right?! LOL Apple (rolls eyes) They could do like Samsung and use one screw for everything.. but oh no.. there is some OCD engineer that just likes SCREWING with people!

I replaced the screen assembly on my Verizon LGG5 with a digitizer & frame assembly & now the Cellular signal has dropped dramatically, any idea's what I might have done? I'm not seeing anything jump out at me. Thanks for your input in advance.
