Quote from Joe Fleming:
This is a great guide in helping you dismantle the phone and to remove the existing assembly, however the bit that's actually difficult is not covered, which is installing the new one...when a get a few more minutes I'll write a detailed description of how I did this is and the things to watch out for (it took me bloody ages). Any questions in the meantime feel free to message me!
Would love to read your writeup and tips for installing the replacement. Thanks, Bernard
