How to Downgrade iOS 27 Beta to iOS 26

A comprehensive step-by-step guide to safely downgrade from iOS 27 Beta to the stable iOS 26 release. Learn the proper procedures, requirements, and precautions to ensure a smooth transition.

Important Warning
Downgrading iOS can result in data loss and may void your warranty. This process will completely erase your device and restore it to iOS 26. Make sure to create a complete backup before proceeding. Apple may stop signing iOS 26 at any time, making this process impossible.

Why Downgrade from iOS 27 Beta?

While iOS 27 Beta brings exciting new features and improvements, beta software can sometimes cause issues that affect daily usage. Common reasons for downgrading include:

  • Battery drain issues and performance problems
  • App compatibility issues with third-party applications
  • Stability problems and frequent crashes
  • Missing features that were available in iOS 26
  • Need for a stable system for work or important tasks

Requirements Before Starting

Before beginning the downgrade process, ensure you have all the necessary requirements:

Computer
Mac or PC with latest iTunes/Finder
USB Cable
Original Lightning/USB-C cable
iOS 26 IPSW
Downloaded from Apple's servers
Battery Level
At least 50% charge
Backup

Time
1-2 hours for complete process

Step-by-Step Downgrade Process

Create a Complete Backup

Before proceeding, create a comprehensive backup of your device:

  • Tap "Back Up Now" and wait for completion
  • Alternatively, create an iTunes/Finder backup on your computer

  • Ensure the file is completely downloaded and not corrupted
Example: iPhone15,2_16.7.2_20H115_Restore.ipsw

Put Device in Recovery Mode

Enter Recovery Mode to prepare for the downgrade:

  • Connect your iPhone to your computer with a USB cable

  • Stable internet: Ensure you have a reliable internet connection throughout the process
  • Be patient: The restore process can take up to an hour, don't disconnect your device

Common Issues and Solutions
