Follow this guide to replace the front camera on your iPad Pro 11" 2nd-1st gen.
This guide is written with an ***A2228*** (Wi-Fi only) model iPad Pro. If your iPad is a different model, there will be some minor visual discrepancies and extra steps.
Since the battery can't be disconnected directly after removing the display, ***completely discharge the battery*** until the iPad shuts itself off before attempting this repair.
