If the issues are significant and nothing else has worked, contacting Apple Support could be a good option to revert my iPhone to older iOS 18.

Instructions: If you want official help to revert your iPhone, you can contact Apple Support directly, or use Apple Diagnostics to run a hardware check before proceeding with any downgrade attempts.

Its advantages include getting professional guidance on how to safely revert my iPhone to older iOS 18, official hardware diagnostics to rule out device issues, and step-by-step advice tailored to your situation.

This allows you to seek verified advice and diagnostics before attempting to roll back your iPhone. It is suitable for users who have tried all self-help methods and want to confirm if there are underlying hardware issues before attempting any system changes.
