Back cover broken, and battery and dock connector problems.
In reviewing your step by step instructions before ordering parts. I determined bottom screws needed the recommended replacements. Ordered parts and kit and all arrived in a few days. Sat down used my magnetic pad, previously ordered, and only used tools provided in kits. The instructions were very helpful, and were right on on possible problems I might encounter. In a short time, and day, I had completed tasks, charging and phone back in use.
Reviewing instructions, and using magnetic pad, and tweezers have always been a great help. Do not under estimate your self, you can do it!
