are there any component which are “married” with the mainboard other then the home button?
Be very careful when disconnecting the battery. The most common technician related damage on the 8 series is knocking off battery gas gauge. When that happens the phone will restart every so often and will only report like 1% battery regardless of how long you charge it. On the bright side, it can be fixed by someone who is skilled in microsoldering. Also when you replace the screen you will lose TrueTone unless you’ve got a special programmer which you can pick up for like $50 from Mobile Sentrix. Just keep yourself organized and take your time. It may be worth while to have a replacement battery on hand. I know when I’ve done some charge ports and even just battery replacement in general I have a tendency to bend the battery and that’s not something I would feel confident in reusing. One last bit, make sure you put the right screws back in the right place. If you don’t you run the risk of causing long screw damage. Best of luck!
