How to get iOS 18.7.7 since it already updated to 26.4
My phone auto updated to 26.4. I just received a news update from Malwarebytes not to install 26.4 but to install 18.7.7 due to Apple expanding a patch for DarlSword. How can I get the 18.7.7 so I can get the expanded patch?
Thank you
iPhone 16e, iOS 26
