The initial "cracking" of the case was the hardest part. I found I didn't need any of the parts kit (aside from the battery). My handy Swiss army knife provided the needed leverage and the tip to use a cut up soda can as spacers was spot on. I found it wasn't necessary to disconnect the audio cable at all. Reconnecting the power cable took a few tries, but the case popped back on and locked in without any fuss whatsoever (damage to clips/case was negligible). Happy Hunting!
