Okay! First of all, the key thing in this process is loads of patience and Gud sorting. Seriously taking ur iPhone apart is tricky and u don't wanna mess up the screws here and dere so be careful.
Followed this guide from step 1 to 31 and back again, and voila my home button was working again...
Just a little tip abt the EMI fingers, they are extremely fragile, I broke one of mine, and had to tape it placing properly fr the proper contact.
Also make sure u have screwed down each bolt properly in place, becoz I wasn't able to close the lid after complete reassembly. Checked the screws and it all fit well finally.
Thnx a lot ifixit and other users for ur invaluable content and stuff.
I really feel like a worthy techie now. :P
