Preparing your iPhone 12 for a factory reset
Begin by ensuring important data is preserved and accounts are signed out to avoid reactivation issues.
Back up essential data
Use iCloud or connect to a Mac with Finder to create a current backup so that apps, messages, and settings can be restored later if needed.
Sign out of services and remove accessories
Turn off Activation Lock by navigating to Settings, tap your name, then choose Sign Out and deactivate Find My. Remove cases, screen protectors, and SIM cards if required.
