futurerestore VS cicuta_virosa

Blobs are a .shsh2 file that is used to submit a request to Apple to restore/update to an iOS or iPadOS version. It’s basically Apple’s signature for iTunes or idevicerestore (a library for restoring Apple devices) to go ahead and install an update to your device. Normally this is just a thing that happens when your device is in recovery mode. This process can be faked and taken over, however. A computer program called futurerestore (https://github.com/marijuanARM/futurerestore) can use those .shsh2 blobs to fake that in ways that I can’t personally explain, but it does. You can also save these blobs if you’re a jailbroken user, which makes it possible to restore or upgrade to certain iOS/iPadOS versions after Apple has stopped giving those signatures itself. For example, if you have saved blobs for iOS 14.3 and you’re on iOS 13.7, you can update or restore to 14.3 today, even though the versions that are signed at the moment are iOS 14.4.2 and 14.5.

That was the old version of future restore. Use https://github.com/marijuanARM/futurerestore and if you want a GUI use https://github.com/CoocooFroggy/FutureRestore-GUI

Your iPhone needs blobs to restore/update/boot(?). Apple only gives (signs) blobs for the firmwares they want you to be on (the latest versions). When you save a blob, you can use a 3rd party program, like FutureRestore, to use them blobs as opposed to having apple give you the blobs, they are saved locally, instead of being generated by apple's TSS server.

There isn’t any problem using latest sep and baseband on futurerestore v194. I, and many others on r/jb discord have used it and it’s restored just fine

that's the irecovery issue, see https://github.com/marijuanARM/futurerestore#restoring-on-windows-10

Okay, I was using marijuanARM's version from this, but I'll using opa334's build. Thanks again!

I can almost guarantee so many exploits wouldn't be sold to companies like Cellebrite or to foreign governments, or even given out for free, if Apple paid market rate for them. They won't though, because they prefer to reflect and obscure, pretending that the problem doesn't exist.

Okay, I KNOW I'm going to sound like an ETA kid, but let me assure you, I'm on iPadOS 14.6 anyways, so I'm going to be sticking to checkra1n for a while now. I heard there was some news for iOS 14.4-14.4.2 and possibly 14.5, hinted here, but not as likely. I've heard that they need a kernel exploit before anything can be declared finished, which makes sense. Then one got released. So then I was told to wait until all the iOS firmware that were affected were unsigned. Strange, but iOS 14.5 was signed at the time, so I went along with it. Then iOS 14.5 got unsigned. So why isn't unc0ver updated? I mean, it is a bit hasty, considering some of us are still blown away by the fact that the unc0ver team even came back, but what about the info I was heard?

Modernpwner, the team that found the iOS 14.3 and below exploits for jailbreaks (unc0ver and Taurine) has hinted at a possible bypass that could lead to a jailbreak for 14.5 (PAC bypass section of https://github.com/ModernPwner/cicuta_virosa). You could theoretically update to either one of these versions right now since they’re being signed, but given the time it takes for jailbreaks to become a thing, these versions might not be signed by Apple if or when a full jailbreak is released for them. You’d have to play the waiting game for a good while if you update now, and none of these exploits are guaranteed to be stable enough for a full fledged jailbreak anyways. That’s why blob saving is so powerful!

With the release of iOS/iPadOS 14.5 and the public disclosure of security content for 14.5 (https://support.apple.com/en-us/HT212317), as well as the potential for another exploit for 14.5 from Modernpwner (PAC bypass section of https://github.com/ModernPwner/cicuta_virosa), updating looks enticing right now. However, you don’t have to lose your jailbreak and play the waiting game.

If you remember how we got our 14.3 jailbreak, ModernPwner released an exploit named "cicuta_virosa" that worked up to 14.3. On the bottom of the README, he mentioned the following:
