Save iPhone 4 SHSH Blobs for iOS 4 with TinyUmbrella 4.00.49

by iPhoneHeat on Jul 2, 2010

TinyUmbrella goes 4.00.49 and can now save SHSH blobs for iPhone 4 running iOS 4.0. Saving iPhone 4 SHSH blobs for iOS 4.0 is important because when an new iOS firmware for iPhone 4 is out, you won’t be able to downgrade to 4.0 unless you have SHSH blobs for iOS 4.

Once you’ve saved SHSH blobs for iPhone 4 firmware 4.0, you’ll be able to downgrade from any newer firmware to 4.0 whenever you like.

You can also save shsh blobs via Cydia by hitting the Make My Life Easier. But for that your device must be jailbroken and there’s no tool to jailbreak iPhone 4 available yet. In such situations the TinyUmbrella is most useful.

IMPORTANT

Apple stops signing firmware SHSH once a new firmware is out. Once Apple has stopped signing firmware SHSH requests for a firmware version there is no way to get your SHSH for that particular version.
Device does NOT need to be Jailbroken in order to save SHSH blobs with TinyUmbrella.
Your iPhone 4 MUST be connected to the computer to save shsh blobs. For other devices, you can also save SHSH blobs without connecting the device simply by providing ECID.
If you desire to restore your iPhone 4 to iOS 4, make sure you uninstall Wi-Fi Sync before trying to do so. I’ve apparently had the same issue a few other folks had.
So far restores on the iPhone4 are not perfect. They error out locally but the restore does complete – it just needs to be helped along. (Much like downgrades where the baseband update fails). I’ll try to put the functionality in TinyUmbrella to fix this.
