Authentication error 7005

If you are experiencing an authentication error 7005 while trying to erase data on your iPhone 12 Pro, it could be due to several reasons. Here are some troubleshooting steps you can try to resolve the issue:

1. Make sure you are entering the correct password. It's essential to enter the correct passcode or password that you use to unlock your iPhone.
2. If you have any VPN (Virtual Private Network) or Proxy settings enabled on your iPhone, try disabling them temporarily and then attempt to erase the data again.
3. To erase your device, you may need to turn off the "Find My iPhone" feature. Here's how you can do it:
   1. Go to "Settings" on your iPhone.
   2. Tap on your name at the top.
   3. Select "Find My" or "Find My iPhone."
   4. Disable the "Find My iPhone" toggle.
4. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
   1. Restart the device. That's it.
   2. Still not solved --> Force restart iPhone - Apple Support
5. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
   1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
   2. You can return settings to their defaults without erasing your content.
   3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
6. Make sure you have the latest updates installed.
   1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
   2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)

If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.
