1. Prepare Your Workspace: Ensure your workspace is clean, well-lit, and free of static electricity. Gather all tools from the kit.
2. Power Off Device: Completely power off your Samsung Galaxy S10.
3. Remove SIM Tray: Use the SIM ejector tool to remove the SIM card tray.
4. Heat the Back Cover: Carefully apply heat to the edges of the phone's back cover using a hairdryer or heat gun (not included) to soften the adhesive.
5. Pry Open Back Cover: Use the suction cup and pry tools to carefully separate the back cover from the phone frame. Work slowly and gently to avoid damaging the cover or internal components.
6. Disconnect Components: Once the back cover is removed, disconnect any flex cables that connect it to the main board (e.g., fingerprint sensor cable).
7. Remove Screws and Brackets: Unscrew any screws securing the wireless charging coil, mid-frame, or battery connector bracket. Remove these components.
8. Disconnect Old Battery: Carefully disconnect the old battery's flex cable from the motherboard.
9. Remove Old Battery: Gently pry out the old battery. If it is heavily adhered, apply a small amount of isopropyl alcohol to the adhesive to weaken it. Be extremely careful not to puncture or bend the battery.
10. Clean Adhesive Residue: Clean any remaining adhesive residue from the phone frame using the provided cleaning wipes.

15. Reattach Back Cover: Carefully align and press the back cover onto the phone frame, ensuring all clips engage and the new adhesive creates a secure seal. Apply gentle, even pressure around the edges.
