How To Backup SHSH Blobs (ECID SHSH) Using Firmware Umbrella [Windows]

ECID SHSH or SHSH blob backup

SHSH blobs or ECID SHSH is a unique digital signature that Apple assigns to each iPhoneiPod Touch and iPad.

Whenever you connect your iPhone 3GS or iPod Touch 2G/3G or iPad to iTunes to restore or update iPhone OS firmware, the ECID is sent to Apple servers for authentication and iTunes will proceed to restore the device only if the ECID authentication is complete. 

However, when a user installs the new iPhone OS firmware, the digital signature associated with the earlier firmware is erased. This makes it difficult to restore the iDevice to its earlier firmware. 

Saurik, the creator of Cydia has setup a server, which basically mimics Appleā€™s verification server so that you can downgrade or restore back to the older firmware by making use of the SHSH blobs.

If you have jailbroken your iPhone 3GS, iPod Touch 2G/3G or iPad then this is important because you might want to restore your iPhone to an older firmware if the newer version includes patches that plug the loopholes used to jailbreak the iPhone OS. As you might know, it took the iPhone hacking community, more than two months to release the software tools to jailbreak iPhone OS 3.1.3. So MuscleNerd of the iPhone Dev Team has strongly recommended users to take a backup SHSH blob to future proof it for jailbreaking. 

This tutorial will take you through the step by step instructions to backup your ECID SHSH or SHSH blobs of your iPhone 3GS, iPod Touch 2G/3G and iPad. Please note that this can be a time consuming process if you don't know your ECID.

Please note that this guide is for Windows users only. If you are a Mac user, you can checkout our step-by-step guide for Mac users.

Step 9: You will now be prompted to input your device ECID, version and to select a SHSH repository

a. If you do not know your device ECID, download the USBview application by clicking here. You need to then put your iPhone in recovery mode (you can check this tutorial) and launch USBview.exe. If you are putting your iPhone in recovery mode, please do not forget to take a backup of the contents on your iPhone. You may refer to this article for a helpful guide on backing up your device.  

Select Options -> Config Descriptors and then press the F5 key to refresh. From the USBview left pane, click on 'Apple Recovery (iBoot)'and copy the ECID key from the right side pane.

  • TimW

    Can't you get your ECID by connecting to iTunes then clicking on 'Serial No' on the summary page??

  • http://www.harevan.am vahan

    You dont need to do this for 3g. you can restore 3g without all this hassle

  • TimW

    Or use 'EmailECID' free on Cydia

  • dan

    Do I do this whole process and backup my SHSH blobs BEFORE I jailbreak my 3GS for the first time, or AFTER I have jailbroken it?

  • John

    Thx worked Fine

  • johnny

    i've done the backup, but i don't know how to use it. could anyone give me some link to the guide of how to use the shsh blobs.

  • somasdkjo

    Is there any other way to do the backup without using Firmware Umbrella and JAVA ?

  • Akaiceman81

    So should we upgrade to the 4.0.1 before doing the shsh backup?…

  • Johnny

    I don't see any mention of iPhone 4. Do iPhone 4 users have to do this also? And if so, is the procedure shown above the same?

  • Robert

    the instructions are totally outdated.
    the new program available is called Tiny umbrella – semaphore v4.01.03
    once you launch it, it does everything automatically after you click on Save my SHSH.
    so please change this posting.

  • chris

    Yes PLEASE update this page. I was totally confused until I realized that this web site doesn't care to check if the tutorial they are linking to on a brand new article is up to date or not.

  • chintan vaghani

    Its very simple dear.Activate your phone first using the at&t sim so that it dosent stay on itunes logo.Download spirit from http://www.spiritjb.com and connect your phone to your pc and run spirit.Simple.You get jailbreak thus.Now go to cydia and add source repo666.ultrasnow.com and download ultrasnow to unlock it for any carrier.You are done

  • Joy

  • ahsan

  • DrunkMunki

  • Sergio
