Why doesn't my home button and cellular reception work?

So... After ordering the iPhone 4 display assembly and the dock connector replacement from here at ifixit, the items got home and I did the repair. But I ran into a few problems (quite serious) as this is my first time. I must say that I followed all the guides relative to the repairs I tried to do.

The situations are the following:

I had trouble connecting the home button cable after replacing the whole dock connector part on the phone... So my home button doesn't seem to work because I don't how how to reconnect the cable.

Furthermore, after replacing the LCD and digitizer and struggling to get those cables properly in place to connect them to the logic board, I reassembled everything back together, turned on the phone and I couldn't even do any emergency calls, so there seems to be a problem from my phone picking up the cellular signal, even though the wi-fi antenna works like a charm!?

And after examining the final product of the repair I noticed that one of the sides of the display assembly is lifted up from the steel frame - I was totally shocked! Probably a cable folded on itself and created additional volume so one of the sides was lifted. I tried to gently click the Display together with the steel frame on the side and no luck... So, we are in a pretty bad situation!

To you hardware wizards that are reading this: do you possibly have a wonderful solution that could at least help me with some of my problems? What did I do wrong? Is it just something that's not properly connected or dust in between the connectors? Any help would be apprciated.

P.S.: I am rebuilding this old iPhone 4 for my mom.

For home button most likely home button flex cable was broken during the installation.

Regarding reception check this picture

make sure antenna is clipped on its place correctly and small circle antenna connector is still on its place,

see also if small blue color coil on its place as well as small brown resistor next to it

any of this 3 will give you a problem with reception if damaged
