User level: Level 1 (4 points)Hello Apple Support,
I have an iPhone 13. It originally had iOS 18, but I updated it to iOS 26 and later to iOS 27.
I really want to return to iOS 18.
Is it possible to request a device-specific SHSH2 signing ticket or receive special authorization to restore iOS 18?
I understand that iOS 18 is currently unsigned, but I would appreciate any official assistance or alternative solution.
Thank you.

If a second answer will help: NO, Apple will not help you downgrade iOS on your device. Apple has never supported downgrading to begin with. And just so you know, this is a user to user only forum, not Apple Support. But even if ask Apple, the answer will be an emphatic NO.

No. Downgrading would reintroduce patched security holes.
For reference, the people on these boards are mostly other customers, not Apple employees.
