1. Force Restart Your iPhone

A force restart is often the first and simplest solution to try. It can resolve minor software glitches.

  • iPhone 7 and 7 Plus: Press and hold both the Side button and the Volume Down button until you see the Apple logo.

2. Check Your Network Connection

Ensure your iPhone has a stable internet connection, as activation and updates require it.

  • Cellular Data: If using cellular data, verify that it is enabled and that you have sufficient data allowance.
  • Airplane Mode: Toggle Airplane Mode on and off to refresh your network connection.

3. Verify Apple System Status

Apple’s servers may occasionally experience downtime, affecting activation and other services. Check the Apple System Status page:

  • Visit the Apple System Status page (search on Google for “Apple System Status”) to see if any services are currently unavailable. If there are issues reported, wait until they are resolved before proceeding.

4. Update iOS via iTunes/Finder

If you can access a computer, updating your iPhone through iTunes (or Finder on macOS Catalina and later) can bypass issues that prevent over-the-air updates.

  • Connect to Computer: Connect your iPhone to your computer using a USB cable.
  • Open iTunes/Finder: Open iTunes (or Finder on macOS Catalina and later).
  • Select Your iPhone: Select your iPhone in iTunes/Finder.
  • Check for Update: Click on “Check for Update.” If an update is available, download and install it.

5. Restore Your iPhone in Recovery Mode

DFU mode is a deeper restore that bypasses the operating system, which can resolve more severe software issues. Like Recovery Mode, this will erase all data.

  • Enter DFU Mode: The steps vary slightly depending on your iPhone model. Search online for “DFU mode [your iPhone model]” for specific instructions.
  • Restore via iTunes/Finder: In iTunes/Finder, you will see a prompt to Restore. Choose “Restore” to erase your iPhone and install the latest iOS version.

  • Liquid Damage: Check for signs of liquid damage (e.g., corrosion, water marks).
  • Physical Damage: Look for cracks, dents, or other physical damage that might be affecting the device’s functionality.

If you suspect a hardware issue, contact Apple Support or an authorized service provider.

8. Contact Apple Support

If none of the above steps resolve Error X99 Stan, contacting Apple Support is the best course of action.
