Introduction
Use this guide to replace the USB-C charging port and daughterboard on your Samsung Galaxy S20 Ultra.
Before you begin, refer to the Samsung Self-Repair document for safety information.
Note: Retaining water resistance after the repair will depend on how well you reapply the adhesive, but your device will lose its IP (Ingress Protection) rating.

After you've completed the repair, download the Samsung Members App from the Galaxy Store or the Play Store, and follow the Samsung Self-Repair document (beginning page 9) to make sure your device is fully functional.

All of these guides mention the reapplication of adhesive at the beginning of the guide, but none of them discuss how to reapply and the kits don't include adhesive. Seems like a pretty important oversight!
This guide is written very well. I followed it exactly, took my time and had no problems except reapplying the adhesive to the back cover and putting it back on straight was a challenge. I was successful but it was a stressful moment. Lol. As for the comment above about the fact that they did not include the adhesive, the "kit" that I ordered had the new charging port with tools, new screws, and the adhesive needed to replace the back cover. I tried to order just the part only but they said it was not available so I HAD TO order the kit. Maybe that is why they only sell the kit now? Anyway, my phone works like new again. Thank You IFIXIT!!
