Steps:

1. Power down your phone and unplug any cables.
2. Insert a SIM eject tool, bit, or a straightened paper clip into the small hole on the SIM card tray on the upper left edge of the phone.
3. Press firmly to eject the tray.

4. Remove the SIM card tray.
5. When installing either a SIM card or a microSD card, make sure they're in the correct orientation and sitting completely flush with the edges of the tray before reinserting the tray into the phone.

6. The back cover is held in place by plastic clips.
7. Insert an opening pick under the small notch in the SIM card tray slot.

8. Position the opening pick at a steep downward angle between the back cover and the screen assembly.
9. Slide the opening pick down the left edge of the phone to release the plastic clips.

10. Turn the opening pick around the corner and continue to slide it along the bottom edge to release the plastic clips.

11. Slide the opening pick up the right edge to continue releasing the plastic clips.

12. Slide the opening pick along the top edge to release the remaining plastic clips.
13. Don't try to fully remove the back cover just yet, as it's still connected with a cable.

14. With the phone laying screen-side down, carefully lift the right edge of the back cover, opening it like a book.
15. Take care not to strain or tear the attached fingerprint reader cable during this procedure.
16. Lay the back cover next to the phone.

17. Use a Phillips screwdriver to remove the 3.8 mm‑long screw securing the fingerprint reader bracket.

18. Use a pair of tweezers or your fingers to remove the fingerprint reader bracket.
19. Take care not to puncture the battery with sharp tools—a punctured or creased battery may leak dangerous chemicals or cause a fire.
20. During reassembly, make sure to slide the bracket's edge back into its slot under the motherboard cover.

21. Use the pointed end of a spudger to disconnect the fingerprint reader by prying the connector straight up from its socket.
22. To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Don't press down on the middle. If the connector is misaligned, the pins can bend and cause permanent damage.
23. Remove the back cover.

24. A white sticker might cover one of the top screws. Pierce through it with the tip of your screwdriver or use a pair of tweezers to remove it.
25. Use a Phillips screwdriver to remove the ten 3.8 mm-long screws securing the motherboard cover.

26. The motherboard cover is further held in place by plastic clips.
27. Insert an opening pick under the right edge of the motherboard cover.
28. Twist the opening pick to release the plastic clips.
29. During reassembly, clip in the motherboard cover on the top left first.

30. Use a pair of tweezers or your fingers to remove the motherboard cover.

31. Use the flat end of a spudger to disconnect the battery cable by prying the connector straight up from its socket.

32. Be extra careful to not puncture, bend, or deform the battery during the next few steps—a damaged battery may leak dangerous chemicals or cause a fire.
33. Use your fingers to peel the two outer adhesive tabs off of the battery.

34. The battery in the Nokia G42 5G is secured to the frame with adhesive. Pull tabs are provided to separate the adhesive and remove the battery.
35. Use your fingers to peel the center green pull tab off of the battery.
36. Using one hand to hold the phone steady, use your other hand to slowly and steadily lift the center green pull tab up to separate the adhesive securing the battery underneath.
37. If the green pull tab rips, use the outer clear tabs instead.
38. If you have any difficulties with stubborn battery adhesive, you can contact Nokia's phones support.

39. Peel the battery off of the adhesive film and remove it.
40. Don't reinstall a damaged or deformed battery, as doing so is a potential safety hazard. Replace it with a new battery.

41. Grab the bottom right edge of the leftover adhesive film and pull it towards the top of the phone with steady force to remove it.
42. To install a replacement battery:
43. Apply isopropyl alcohol (>90%) to the old adhesive and use the flat end of a spudger to scrape it off.
44. Remove the clear liner on the pre-cut battery adhesive and apply the sticky section to the battery well. Remove the opaque liner before continuing reassembly.
45. Remove the battery adhesive film from its liners and apply it to the battery.
46. Align the bottom edge of the battery (the edge without adhesive) with the bottom edge of the recess.
47. Lower the battery down and press firmly to secure it in place.
