Home and Power buttons not working after replacing back

I replaced the back and chassis on my iPhone 8 today after shattering the rear glass. I got everything refitted and connected up and discovered that the power and home buttons aren’t working. While carrying out the repair when I was tightening the Taptic Engine down to the metal back plate the studs sheared off so I had to attach the Taptic with double sided tape. When I took the phone apart again I discovered that the Taptic ribbon cable was damaged. If the Taptic isn’t working will this stop both the home and power buttons functioning?

everything on the phone is working (sound,camera,flash etc) just the home and power buttons are doing nothing. I didn’t replace the screen, only the back and chassis. Trying to decide whether to just replace the phone or start replacing more parts?

Hello, the iPhone 8 series home button uses a haptic feedback system - where the Taptic Engine mimics the vibration of a click. If the iPhone 8 home button still works, but vibration doesn’t work then yes that is probably due to the broken Taptic Engine. However, if it doesn’t register a touch when clicked it could be a faulty home button connection to the screen, or damaged home button (did you replace the screen?). As for the power button, that is a part of one flex cable, so if the volume buttons, flash, rear microphone and ringer still work, then you most likely tore or damaged the cable in the power button section, or as the power button is mounted using tricky brackets, check to make sure it clicks properly. I don’t see how a broken Taptic Engine would result in the power button not working. Hope this all helps (:

Hmmm... new power and volume button flex cables aren’t that expensive - only around $10 from reputable aftermarket sellers. Maybe give one of those a try. Taptic Engine’s that are of decent quality are also usually around $10 from what I remember.
