As there is no ifixit guide for this at the moment, here is a video on YouTube which demonstrates how this is done: https://youtu.be/U_N55_Tdz2U (Perform at your own risk!) There likely hasn't been a guide created for this as it is out of the question for the average ifixit user due to the requirement of soldering (Although I do know of similar guides that do exist on ifixit so it may just be that nobody has created a guide yet)
