Busted back on iPhone 4 so I took it upon myself to get some thing custom. So i had no choice to remove the back cover come to realize the tools i had where no use too big. So then i turned to ifixit where i got the liberation kit and Presto it was all good.
I was as easy as A-B-C although i had trouble with those.
Other than placing 50 different orders for parts. Just do one big order and follow the instructions offered by ifixit and you're good to go.
