Hi, I accidentally upgraded my test device (iPhone 13 mini) to iOS 26. I really need to downgrade it to 18.7.X again. It seems this isn't possible since Apple doesn't sign the .ipsw anymore.
Is there really no way for a paying developer to downgrade her test devices?
(Please don't tell me to use the support forums, this is a concerning a developer test device)

That’s correct.
The only exception to this rule is if the new iOS version is a beta seed, in which case you can roll back to the previous public release. For advice on how to do that, see Apple Beta > FAQ > Support > How do I leave the Apple Beta Software Programme?

This answer is the same for both developers and users.
