I took it as a challenge. Also to get a new one would cost me about $400. This was about $70
It went fine. On the reassembly I lost the earpiece Speaker 2.3 mm screw. I was trying to put it and it jumped off the table. I looked for it but no luck. So I just put the 4.0 mm and hope it works. It did. I'm really glad . My phone is working perfectly I haven't try the face time. I'm sure it will work, I don't see why not.
If you get all the tools and good working area it is easy to follow all instructions and most likely you will achieve just about anything you want to repair.
