CTOnews.com, November 15 (Xinhua)-- after Apple closed the iOS 17.0.2,17.0.3 signature verification channel this month, Apple closed the iOS 17.1 authentication channel today, meaning that upgraded users can no longer downgrade or revert to the firmware version.

Apple launched iOS 17.1 firmware on October 26 this year. This update mainly brings "AirDrop Internet transfer" and "improved Apple Music" functions, enhances "standby display" for iPhone, updates Apple Pencil (USB-C) support for iPad, and improves radiation problems in iPhone 12.
