Great guide. Be careful that the silence button is workable before reassembling everything. It is easy to think the switch is in place when it really isn’t. Also, be careful when adhering the new cable to the housing as accurate alignment is essential for the cable to not have a significant kink in it when trying to align it with the logic board. I found that following the markings on the back housing were pretty close when adhering the cable and deciding where to put it. I got sick of messing with battery adhesives and tried to use none and the battery is totally stable once the phone is reassembled and doesn’t rattle around at all.
