This wasn't that difficult of a repair.

Meu Problema

Realised the plug wasn't working when I had to fiddle with the cord to make contact in charging port.

Minha Solução

Easy. The only thing that went wrong was it seemed the phillips head screwdriver was too small as it stripped the heads of 1 of the screws way too easily.

Meu Conselho

The only thing I think I would suggest is to keep the screws in order so you know where they go when you reassemble the parts. I also replaced the battery (and highly recommend doing so) at the same time as the phone is already taken apart and the battery is a pretty inexpensive part. I don't know if I'd go as far as to say the difficulty level is 3 out of 3. maybe a 2+. Thanks!
