The instructions on desoldering the port should not be followed in this guide, as you can clearly see in the pictures they damaged the motherboard. There are more than 4 connections that need to be desoldered. The four connections shown are only anchor points, and there’s several pads (i believe six, aside from the four anchor points) joined to the port that actually transmit the signal. If you do not desolder these points before removing the port, you WILL damage the motherboard significantly and it will require fairly complicated repair, or the replacement of the motherboard entirely, which is the most expensive component of the phone and holds all of the user information. Awful guide.

Removing the battery is 100% unnecessary for replacing the lightning port. Considering how difficult it can be to remove one of these batteries, I’m really scratching my head over why you would have included it in this tutorial. Seems its gonna cause people a lot of extra grief, and might prevent some capable people from undertaking this procedure on the basis of not having proper tools specifically for removing the battery.
