Our iPad's port likely got some water damage, and was completely corroded. The symptom here was the iPad would no longer charge.

I apologize for the lack of pictures. I didn't intend to create a guide, but after performing this repair I thought it would be valuable to at least record my process.

You'll need some tools: 00 phillips bit, thin razor blade, thin metal spudger, guitar picks or popsickle sticks, and a way to heat up your iPad. I purchased the replacement USB-C port and pre-cut replacement adhesive stips.

It took me two hours. I've replaced iPhone screens and batteries before. If you are patient, careful, and have some experience fixing things, then you can do this.

This isn't a novice repair, but it isn't technically difficult. You need to be comfortable working with small screws and have reasonable dexterity to control your cutting tools well.
