Using TinyUmbrella you can save SHSH blobs for iPhone 4, 3GS, 3G, iPad, iPod Touch 4G, 3G, 2G and AppleTV 2g. In this guide you’ll learn how to save SHSH blobs for iOS 4.x, 3.1.x firmware with TinyUmbrella in both Windows and Mac OS X.
What Is TinyUmbrella?
TinyUmbrella is a unified version of Firmware Umbrella and TinyTSS. For more details,
When you try to restore an older firmware on the devices listed below, Apple won’t let you do that. Once you ‘upgrade’ they don’t let you downgrade. The way they stop you is basically by a simple response that iTunes receives when you try to restore the firmware of your choosing. See, the firmware is now signed for the below devices. It is signed with a unique id (ECID) that only your device has. Apple takes the firmware version files and combines them with your ECID and generates a hash that ONLY APPLE can generate. iTunes packages up this valuable information and sends it to your device. Your device checks the information and verifies the signature (making sure it really came from Apple because it CANNOT be forged as the encryption is very high). If the signature matches then the restore process can continue. If the signature does not match, the device raises an error and the restore process stops. Apple stops signing older firmwares once a new one is out.

What Is An SHSH Blob?
An SHSH is a secure signature hash. Basically its a unique key. (To avoid a lengthy discussion).
Why To Save SHSH Blobs?
Apple only allows you to restore to the firmwares they ‘sign’. This ‘signing’ only lasts for a limited time. Once they stop ‘signing’ the SHSHs for a firmware, there is no way to restore that firmware ever again. The core purpose of saving SHSH blobs is to secure future jailbreak. If you want to downgrade back to and older iOS 4.x, you will need your SHSH blobs saved either on Cydia or in your computer via TinyUmbrella.
Cydia can save SHSH blobs automatically (If you have ever tapped the “Make My Life Easier!”), it is recommended to use TinyUmbrella to ensure that you have SHSH blobs on file both on Cydia and on your Computer.
- TinyUmbrella can save SHSH blobs regardless of jailbreak.
- You can save SHSH blobs for any latest firmware even if you’re on an older.
- It does not matter what firmware version is on the device TinyUmbrella will get the currently signed firmware + all blobs saved at CYDIA Server (if any) by default.
- iPhone 2G and iPod Touch 1G users do NOT need to save SHSH blobs.
- iPhone 3G, and iPod Touch 2G (MC) users need SHSH blobs for iOS 4.x/newer only. SHSH does NOT apply to iOS 3.x for these devices
Follow the Steps mentioned below to save SHSH blobs of iOS 4.x, 3.x firmware for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 3G and iPod Touch 2G (MC).
