    Use this guide to replace the USB-C charging port and daughterboard on your Samsung Galaxy S21 Ultra.
    Before you begin, refer to the ++[document|28390|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.
      ***To reassemble your device, follow the instructions in reverse order*** and perform the opposite actions, e.g., "reattach" instead of "removing." Skip steps that use heating and prying, and pay close attention to the 📌 bullets as you work through the steps.
      After you've completed the repair, download the Samsung Members App from the Galaxy Store or the Play Store, and ++[document|28390|follow the Samsung Self-Repair document]++ (beginning page 10) to make sure your device is fully functional.
      ***To reassemble your device, follow these instructions in reverse order.***
      Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]].
