Downgrading iOS 26 on iPad Pro

Apple invite submission of constructive comments and feature requests via its Product Feedback portal. If you would like Apple to reconsider recent changes, this would be the most appropriate and effective path to having your voice heard:

Feedback - iPad - Apple

While you are unlikely to receive a personal reply, it is our understanding that all feedback is logged and forwarded to the appropriate development team(s) for consideration.

Rolling-back to an earlier version of iOS/iPadOS is not possible. All System Updates are digitally signed by Apple - and can only be installed whilst the digital signatures remain valid. After release of a new iOS/iPadOS version, the immediately preceding version continues to be digitally signed by Apple - however, usually within a few days, Apple will revoke the digital certificate with which the earlier version is signed.

Perhaps consider that iOS/iPadOS updates include both functional and essential security updates. Restoring an earlier version of the OS would, by removing essential security updates, undermine the security of your device and your personal data. 

No. Downgrading is not supported.

I’ve never been so bothered by an update. I hate it and just want the option to have my phone display and work the way I want. With all the technology out there, why am I limited in customizing how the thing I use daily looks?
