Hey guys i´ve a big problem with my iphone 5 concerning the new touchscreen.

I´ve bought a complete touchscreen, with a new home button, camera and so on.

Today i´ve put the new one into my iphone in general it works but there are 2 big problems:

first the new touchscreen doesn´t keep on the iphone means that i´m not able to reassembly the screen at my phone because it´s almost moving and doesn´t i don't know how to say it "click" into the holes.

I think it´s important to know that I've changed the hole back cover but im as good as sure that I've put the parts that hold the screen the right way.

the second problem is about the home button and the two screws on the downer side of the iphone.

The hp doesn't react to anything and the two screws to not leave in the phone they do net become i don't know how to say it english im sorry

i mean so that they do not fall out on their own.

Would be great if you could help me because i really don't know what to do and need my iphone
