would someone mind explaining how I can update my 15.0 device to 15.1 without updating to any later version in lieu of the recent jailbreak, and what blobs are?

you can't update to 15.1 without blobs currently

#

blobs are signing tickets for an ios version that can only be gotten when that version is signed

#

so do I basically need to be jailbroken in order to do that

#

you can save blobs without a jailbreak, i would recommend blobsaver as it can read the required info to save blobs for your device easily

#

you can use them without a jailbreak but it's more complicated

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.
