Reply to JHON. SHSH They can only leave Apple, you request a restoration with a firmware and Apple has to give you your signature so that you can install it, otherwise the restoration will fail. We can say that it is an electronic signature, to make a comparison it is like a DNI identity document in Spain with the difference that you need a new one for each new firmware that Apple releases.

What do we use SHSH for in the world of jailbreak? We use them to be able to restore to previous versions, as we have said we can only update to the latest version because Apple only signs that version. Sometimes they are used for a type of jailbreak that requires a beta file, for example, for the untethered MONTE jailbreak we need iOS 4.

Whether you have jailbroken or not, there is another way to save them, a program called TinyUmbrella available for Windows, Mac and Linux. What we do is request the signature SHSH from Apple, and save it on a Cydia server, you can also save them on your computer in case there is any catastrophe to be able to send them back to the Cydia server.

When you install a new firmware iTunes connects to an Apple server and requests the SHSH, what we do is modify the host file of our computer the file where our computer tells iTunes where it has to connect to request the SHSH so that instead of asking Apple, ask Cydia for them, this way we can get the signature to restore to older firmwares.

I've read articles like these for months everywhere I'll tell you about my case: I had to restore but it wouldn't let me install the 4. I guess it's because of the SHSH issue. I will try to jailbreak a mac or hackintosh, or macos from vmware with the latest redsnow since there is no windows version. Will I need the TinyUmbrella to put them in the iphone 4 or just running redsnow would be enough????

In your specific case you don't need tinyumbrella because as it is only an iOS 4. I yesterday already desperate for not sharpening my 3Gs new bootrom I tried to put the firm 4.

Good tutorial, but excuse me I still don't understand some things. I have iPhone4 with 4. Now I want to jailbreak unthethered and it asks me for the iOS 4.

In another thread he explained it, people who have received their 4th generation iPad, iPhone or iPod Touch with the firm version 4. This happens because one of the indespensable requirements to do so is to have saved the SHSH of the 4.

It happens that to all those of us who had the iPhone with 4. I hope this helps those who are desperately looking for a way to downgrade a previous firm or simply Jailbreak their device, which came from the factory with firm 4.

Now comes my question, could I jailbreak unthetered to 4. Greetings and sorry for the billet and thank you very much in advance. Fer, indeed, if you had it in version 4. Jose, to restore an external firm NOT ONLY it is necessary to have the SHSH saved, if not it is also necessary to modify the host file of your PC or Mac, if you do not do it, you will not be able to restore to an external firm, in the This article's tutorial is very well explained, that is because if the host is not modified, the signature query is made to Apple and its servers answer negatively and give you an error, on the contrary if the host is modified, the query It is done to the Surik servers and in case of having the SHSH saved on their servers, the answer is affirmative, with which the restoration continues and it is possible to do it, perhaps that has been your problem or the reason that you have not been able to restore even having the SHSH saved.

Jose, if you had the SHSH of 3. Texuas, thanks a million. You do not know the joy that you have given me. Well, I'm not going to look for a tutor, and try to do it. Thanks again. I bought a 4gb Iphone 32 two weeks ago in the second hand from a person who had it stored and unused….

Carlos, effectively, saves you the SHSH of the current version of firms, not the one that the iphone has, that is Well, it's a shame because with version 4. This mismatch of interests means downgrading versions is definitely a big "no-no" for users.

Even if you legitimately have a problem with the latest update, or hate the new changes - you're usually out of luck. Companies like Apple even implement security measures to prevent downgrades. Blob Saver is designed to help make downgrading to older firmwares on iOS and tvOS possible, by saving the digital signatures required by iTunes to restore a device to a particular firmware.

Apple has its own digital signature protocol that dictates whether a user is eligible for a firmware restore. This is why, even if you have the correct official firmware files downloaded to your PC, iTunes will throw an error when you attempt a restore to a firmware older than the latest version. These signatures are problematic because they are device-specific and firmware-specific.

That means, every device has its own unique signature for restoring to a particular firmware. No two devices can share the same signature to restore, and no device can share the same signature to restore to two distinct firmwares. However, signatures are not "consumed" - meaning the same signature is used to restore Device 1 to firmware A everytime. This is nice, because you only need to collect the signature for a version once, and you can always downgrade to that version in the future.

Again, you need to collect the signature for each device you own. Apple has one more trick up its sleeve. These signatures are not handed out forever. In fact, Apple only generates signatures for firmwares when they are the latest version. Once Apple releases a newer version, previous version restores will usually get rejected within a matter of weeks. The period of time Apple allows a version to be restored is known as the signing window , because Apple is "signing" firmware restore requests during that time.

As a normal Apple user you wouldn't be able to. It's important to acknowledge that the jailbreak community has simply found a clever way to trick iTunes into generating the signature for a device when they are not truly requesting for a device restore.

Saving SHSH Blobs for every new version to release means that eventually, when a jailbreak comes out for any of the new firmwares, you can safely restore and jailbreak long after Apple has stopped signing that version. Otherwise, it is a great way to increase the value of your device. Any device that has the ability to downgrade to older versions has more value than a device that can't downgrade.
