Useless when Apple won't activate them anymore.

Can’t you have the blobs that would let you go back? I think only iOS 14 won’t let you go back. Not sure if you already need to be jail broken or not to allow this.

  you mean shsh blobs? Didn't they turn obsolete years ago when they patched the firmware to require random nonces?

    Ah okay. The procedure now is to give your device info and get the shsh blob during the signing period. Perhaps that’s the way to get the random nonce you’re referring to? So that’s pretty limiting. Regardless, there was some talk of iOS 14 Not allowing downgrading. Not sure if that’s when jailbroken or in any way. ——- I still jailbreak myself. But don’t pay much attention to the scene. I think iPhone 5 is when the peak of jail breaking ended. That’s all the way back in 2012. And kept decreasing in popularity I install the same sort of tweaks for my own reasons I find very important and not much else. Important enough I’m going to go to stores this week and look for an iPhone 11 [Pro or whatever] that has 13.5 on it, so I can jailbreak again and keep my same iPhone 8 set up.

      Yeah, you used to be able to cache these shsh blobs and reuse them to install the same iOS image in the future again because they didn't change. Since quite a few years the iPhone generates a new random nonce during each restore though and requires that nonce to be signed by Apple to proceed. This makes caching the response useless for downgrading. https://www.theiphonewiki.com/wiki/Nonce https://www.theiphonewiki.com/wiki/Nonce

        I’ve downgraded without issue twice in recent years. Must be a jailbreak thing then. Every one is always saying to save your shsh blobs so I don’t know. I don’t think that wiki or most sites are that up to date with jailbreaking stuff since the peak of jailbreaking was so long ago.
