Use this guide to replace the logic board in your iPad 8 LTE.
Note: this guide is for the LTE version only. For the Wi-Fi version, click here.
Be very careful when you isolate the battery using a battery blocker. The battery contacts are easily damaged, resulting in irreversible damage. If you choose to complete the guide without isolating the battery, avoid using metal tools except when completely necessary (like when removing screws) to prevent shorting the battery and damaging sensitive circuit components.
Some photos in this guide are from a different model and may contain slight visual discrepancies, but they won't affect the guide procedure.
