Thank you for the really detailed guide, I followed this through and amazingly did not break the screen! Although it took an hour at least to remove!

All reassembled and appeared to work fine, but now the microphone does not work, making the phone worthless and unsellable realistically. As I’ve glued the screen back on already, is there anything worth attempting or is it time to give up?

I don’t mind trying to take it apart again but it would be pointless if I don’t know how to fix the microphone. A missed connection perhaps? Everything else works and it is not water damaged at all. Any advice appreciated, thank you!
