Home button dead after battery replacement
Hi, I replaced the battery of my iPhone 7 which worked fine. But now the homebutton is completely dead. No touch id no button functionality. I already disconnected all 3 screen cables and the home button connector on the screen assembly but no luck. Still not working. Hard reset via power and volumen down button also didnt help. No errors from iOS did pop up. It is running iOS 14.4. Any further ideas? Thanks.
Is this a good question?

I "HAD" same problem after replacing the battery in my wife's iPhone 7.)
SOLUTION: Reseat the flex cable connectors into circuit board sockets.
SCENARIO: I knew I had been very careful with the flex cables, so I doubted that I damaged them as was implied above. And the cable connectors "appeared" to be seated okay but the Home button would not work. I discovered that I apparently not FULLY seated the flex cables connectors back to the logic board sockets.
FIX: I removed the metal connector bracket that covers the connectors, carefully lifted the connectors out of their circuit board sockets and very carefully repositioned them slightly (again) and pressed firmly until they "clicked" in place. Yureka! The Home Button began functioning. Saved $70-150 for a new screen!
