You have 2 options, future restore (down to 14 but requires blobs) or iTunes downgrade (down to 15.6rc)

#

im on ios 16 so i think only 15.6rc would work

storm stirrup
#

Well if you have blobs, you can go lower

#

If you don’t

#

Lowest you can go is 15.6rc

gilded merlin
#

storm stirrup
#

Ok

#

Well only option is 15.6 rc

Hey @gilded merlin, have a look at this!

blobsfaq

What's a blob?
It is a file containing a special key specifically for that one device to allow downgrading to a specific firmware.
They're like golden tickets, but instead a digital signature made by Apple that was saved at the time when the signing window was open. If you possess one (or many), keep them safe.

How do they work?
They can be used in a program called futurerestore to restore to a firmware in which the SEP/Baseband is compatible. To check SEP/Baseband compatibility, check /tag sepbb.

Make sure to not use misleading sites.

Regardless of SEP/Baseband compatibility, any/all blobs should be saved for future downgrading abilities.

Can I save them now?
Of course. Blobs can be saved at any time, but it is crucial to save them when Apple releases new firmware, because they can only be saved for versions that are currently signed.There is one exception to this: if you are jailbroken and Apple has unsigned the version you're currently on, you may save onboard blobs for that version.
