Home Button Not Working (Restore Loop?)

Hi, I just got my screen, back plate, and front camera to replace my iphone 6, however after I put it in, I realized that my iphone 6’s home button was not functioning. I tried replugging in all the flex cables, however that did not fix my cause. So, I decided to put my iphone into recovery mode and when I did that it said that there was a problem and my phone may need to be updated or restored. I tried updating, but after the process my iphone went back to the support.apple/support/restore. I then tried to restore however that did not work and it still went back to the support apple restore screen. Whenever I unplug my phone from my pc and turn it on it goes to the Hello apple screen however my home button still does not work. Is this a software problem or is a home button problem? I don’t think its a home button problem because I can use the homebutton to get to dfu and recovery mode. I’ve tried multiple restores and updates however nothing works. Thank you for anyone that contributes!
