iPhone 4 > iOS 4.0.1 Release Seems Imminent “Be Ready” Save Your SHSH Blobs Now!

Posted: June 30, 2010 in GSM Info

By now, most of you might have heard rumors about the iOS 4.0.1 firmware update which Apple is preparing to release tomorrow in order to fix the ongoing reception issue on iPhone 4. Even though the issue is most likely related to the hardware, the buzz is that Apple is preparing a software fix in order to avoid (Apple sold 1.5 million iPhone 4s on the first day) what could be the biggest recall in the history of consumer electronics.

How to Save iPhone 4 SHSH Blobs (ECID SHSH) on iOS 4

TinyUmbrella has been updated to support iPhone 4 (running iOS 4). It is important to save SHSH Blobs (ECID SHSH) files of your iPhone 4 now because of all the rumors going around regarding a new firmware update, which could be released as early as next week. If you have your SHSH blobs on file, you can downgrade anytime to iOS 4 from iOS 4.01 should you need to.

Some important notes for iPhone 4 SHSH blobs before you proceed.

If you desire to restore your iPhone 4 to iOS 4, make sure you uninstall Wi-Fi Sync before trying to do so.

In order to obtain your SHSH you MUST have the device attached.

Restores on the iPhone 4 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.

For Mac users: Copy the app OUT OF THE DMG. The reason you are getting the repeating password prompts is because you ran the app from within the DMG. This is bad. Copy it anywhere and you’ll be fine.

From here onwards, you can simply follow the steps that i have posted here for iPhone 3GS
and iPod touch. These steps are essentially the same for iPhone 4 except for some of the notes that I have posted above. Oh and if you want to learn more about what SHSH blobs or ECID SHSH files are, you can do so by reading one of my old article posted here.
