Utter and complete failure. Followed the directions to a 'T' to replace my home button. Home button works now. Digitizer and screen now only work periodically. Degreased the connections with windex and it only made it worse.
Job complete. Took me 2 hours and everything is working as good as new. Excellent guide. The only thing I didn't use was Windex but everything worked fine without it.
I followed this guide slowly and carefully and it worked perfectly, just used tissue instead of windex and everything is fine, saved me £139 that apple wanted to charge me :)
