Hello, we're going to look at how to save our SHSH blobs using a tool called Tiny Umbrella. Saving our SHSH blogs periodically is a must if you want to guarantee your device is eligible to run a firmware which is not the latest. This comes in handy if and when you are required to restore your device (for whatever reason) and the latest firmware is not jailbreakable. Using the following method, you will be able to guarantee you can always restore to a firmware where a jailbreak does exist.

What is an SHSH blob?

Put simply, an SHSH blob is a handshake or signature from apple that allows you to install their firmware on your device. When a new firmware is released apple will stop singing the previous release, not allowing you to install that firmware. What Tiny Umbrella does is make a copy of the "handshake" and saves it for use later, allowing us to install any firmware at any time (providing we have the correct "handshake" or SHSH blob).

So lets begin.

Step one - Getting Tiny umbrella.

The first thing we need to do is download the latest version of Tiny Umbrella. i have supplied a link to the most current versions below...

OS X
Windows

Once downloaded, proceed as you normally would installing any software.

Continue and accept your way though the setup process until you have Tiny Umbrella installed.

Step Two - Getting ready

Now we have successfully installed Tiny Umbrella we can start it up. By now we have connected our device to our computer using apples supplied 30 pin USB transfer cable. Upon first launch you will get a dialog box explaining that Cydia is currently saving SHSH blobs.

I suggest you take their advice and disable "Request SHSH From Cydia" under the "Advanced" tab, in the middle of the app window.

Step Three - Lets save some SHSH blobs.

Now that's all sorted we can proceed to save our SHSH blobs. On the left hand side of the application you will notice a column that displays any devices connected to the computer. Select your device and hit the "Save SHSH" button towards the top right hand corner of the application window.

This will quickly pull any and all SHSH blobs from your device and save them to the directory selected under the "Advanced" tab.

Congratulations! You have now successfully saved all available SHSH blobs for your device. Tiny Umbrella will list all available blobs under "General" when your device is selected in the left hand column.

Check out my other Tiny Umbrella tutorial HERE (under construction) for instructions on how to downgrade your firmware using the Blobs we pulled in this tutorial.

I thought iOS 5.0+ blobs could not be saved :\

[brutal truth]

That ability resumed with 5.0.1. I you have Cydia you'll see they are saved there too.

Done. The images were too large that's why you were having trouble. I cropped a few tighter to take up less room.

I just read this and should clarify that A5 owners (iPad 2 and iPhone 4S) currently cannot use blobs to restore. This is from the iPhone Dev-Team blog.

...A5 owners, who currently have no way of restoring to 5.0.1 once the 5.0.1 SHSH blob signing window is closed.

[Chris230291]

If the tablet runs windows or OS X and has a USB port it can.

[Rik]

Dont know well but i think its android , it can be use?

[Chris230291]

Sorry If it's android you cant do it. It needs to be something with windows or OS X for the software to work.

Today i save my shsh blobs on mac but when i try many times to save after disable " request shsh from cydia" i cannot able to have shsh blobs but when i try after enable it , i save the blobs even it is ok or not, becouse now i want to update my iphone to 5.0.1. Is it ok or not?

[Rik]

After enable "request shsh from cydia"i save my shsh blobs even if i update my iphone 4 on 4.0.1 to 5.0.1 without updating baseband is possible, please let me know how to do?

[Chris230291]

To check you have the blobs saved, look for the ".SHSH" folder on your computer. It's usually under *Username*/.SHSH. Then make sure you see the blob for your device and the firmware you want to restore to.

I believe you can update to 5.0.1, but i think you need to use iFaith to do so (same goes for any 5.x.x firmware).

Take a look at the iFaith tutorial here...
