Unresponsive Touchscreen after screen replacement

[Jacobbottem]

To give some background of why I replaced my screen the reason is because about two months back I dropped my iPhone 7 Plus and cracked the screen and the phone still worked though. Then about a month and half of dealing with a cracked screen while using it the screen went a shade of black that wasn't quite as black as when the phone is powered off. When I forced restarted it would go to the full black screen and when I recieved calls my phone would still ring and it was functional. I decided to replace the phone on my own as a broke college student and I bought a digitizer + LCD off Amazon. I &&^&@@ up on the replacement in two areas. The first being I ripped the cord on the home button so the home button doesnt respond which isn't my concern at this point. The second thing is on the front sensor I riped off some little peice which is I believe the ambient light sensor if I'm not mistaken. When I replaced my phone and turned it on it took forever at the Apple power on screen and it turns on normally once it finally loads but none of the touch response works at all. I doubt it would be a faulty screen as I messed up in multiple areas. I don't have enough money to bring it in to a shop to repair so I'm wondering where I could have messed up so I can try to reconnect something or whatever it needs. If there is a specific part(s) that could cause this please inform me!

Sounds like you damaged the phone trying to do a repair you obviously didn’t have the skill to perform. At this point, it would of been cheaper if you would of just taken it to a shop to get it repaired. Now you have no choice, unless you want a phone that doesn’t work. Take the experience as a lesson learned. Sometimes trying to save money ends up costing you more

You can get a replacement Front Camera/Sensor flex, they're not that expensive and it would likely solve your ALS and maybe Prox issues. As for the screen, you may have damaged the Touch flex or damaged the connector. Take a closer look, preferably under magnification. All it takes is a tiny tear or even one damaged pin to cause issues. I don't know what repair guide you were using but some of the ones available on Youtube are terrible. Try the ones over at iFixit and always read them before attempting the repair so you can determine if you have the proper skills/tools. Everything looks deceptively easy in videos but the stuff inside the phone is very fragile and can be damaged easily.

Okay I got the screen to work by opening my phone up and trying to disconnect and reconnecting things and it oddly worked. The home button is the only thing that doesnt work and I've done the fix where i have the home button on the screen but is there anyway to solder or reconnect this wire on the home button? Also I'm sure its something to do with the thing I broke off on the camera area because now on my iPhone 7+ I don't get that true tone (Yellowish tint) that I had before would that be a result from whatever I broke?

For the Home Button, are you referring the the thin flex cable? If so, these are very difficult to repair. If your TouchID works but not the click function, then that is easier to repair but still requires that it be done by a professional micro-solderer.
