Ayone got problem with stuck in loop recovery mode, and even itunes or mac finder could not restore my iphone 12 pro max. I keep getting this fail message when system almost done. (-1)06A6.FFF. I?

The error code "-1)06A6.FFF" indicates an issue during the restore process on your iPhone 12 Pro Max but there are a few steps you can try to resolve the problem:

1. Ensure that you are using the latest version of iTunes on your PC or Finder on your Mac. Outdated software may not support the latest iOS updates.
2. Use the original Apple USB cable that came with your iPhone or a certified third-party cable. Sometimes, faulty cables can cause connection issues.
3. Attempt the restore process on a different computer to rule out any computer-specific issues.
4. Disable any security software (firewall, antivirus) temporarily during the restore process, as they might interfere with the connection.
5. Consider visiting an Apple Authorized Service Provider if the Apple Store was unable to resolve the issue. They may have additional resources and tools to help.
6. Still not solved --> Force restart iPhone - Apple Support

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.
