I'm trying to downgrade my visionPro to visionOS 1.3. I downloaded the visionOS 1.3 ipsw file from the Apple Developer site (on September 25, 2024), but I'm unable to restore the device using this file.
After checking ipsw.me, I noticed that visionOS 1.3 is no longer signed. This makes me wonder if the 1.3 IPSW file, although available on the developer site, might not be usable anymore.
Has anyone else encountered this issue? Is there any official confirmation on whether visionOS 1.3 can still be restored?
Hey @YusukeYamanaka,
Once the software updates are no longer signed you are unable to restore to them. Upgrading to the latest version of visionOS software provides the latest features, security updates, and bug fixes
You can test your application on older software versions using the simulator, or choose to bump the minimum version of your application to the latest.
Are you able to provide more information as to why you trying to restore to visionOS 1.3?
Thanks,
Michael
