home button not working after back housing change

Hello, this is my first question. I have an iphone 3g with problem on home button.

I wanted to change the back housing and i ordered from ebay (model A1303, yes it is for 3gs but i didn't knew it then).

I started the process but i made one mistake, i put the dock under the bezel and the case had gap between it and the bezel. I opened iphone and the home button didn't work.

I didn't noticed my mistake with the dock and tried to solder the home button with wires to the dock. No success , only a thick layer of solder left at the dock.

After this, i understood my mistake with dock-bezel and fixed it. The home button didn't worked and i thougth it was damaged so i ordered a new one from ebay. I changed it (digitizer come off) and home button still not working.

I "touched" the dock's two metalic sockets (where home button supposed to connect to) with a wire and iphone acted like home button pushed, so dock is ok.

I put two pieces of foil between home button and dock and nothing happened...

So, where is my problem ? Home button is faulty ? or the back housing case is different from 3g and it doesn't allow, with some way, home button to reach the dock's sockets ? I tried to lift the two metalic pieces at the back of home button.

the rear case are the same it should not be the source of the problem... if you put a 3g and a 3gs side by side there is no visible clue until you check camera/video and model no. on settings...

Your home button ribbon is damaged. Replace that and it should be good to go. Kind of tricky though, since you have to separate the glass from the midframe to get to it.
