i've replaced screen but home button doesn't work

Hi community,

i have an iphone 7 plus with cracked screen; i've changed the screen with nothing problems but when i turn on the device, apple logo appears but it get stuck, then i link on itunes the device and i start with the dfu mode to refresh the os to last one version.

now on the screen i can see "push home button to recover data" (or something like this, i'm italian). But home button doesn't work! it doesn't push.

i've order a new home button and i replaced it but it's the same; then i've replace the old broken screen first time with the new button and second time with the old button but nothing work.

please help me,

ty
