I did this repair the other week; it was pretty miserable, and wouldn't recommend it.
However, I made it even worse for myself and didn't pay attention to where the wires that you have to remove re-attach. I've got the three of them put on where I think they go, but now my LTE data connection doesn't work, even though it sees the signal. Anyone have pictures of a Verizon 8X opened up so I can put these things in the correct orientation?
