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 those steps:
Step 1: Download the latest beta version of TinyUmbrella for Windows, Mac or Linux.
Step 2: Make sure you are running iTunes > 9.0. iTunes 9.2 is recommended.
Step 3: Start the program and plug in any ONE of the supported iDevices (iPhone/iPad/iPod touch).
Step 4: Click on “Save My SHSH”. TinyUmbrella will now grab the signature for you.
It will be enabled again once a ticket has been generated to save it to saurik’s server.
This is it ! You should be safe now. Make sure you save the signature for your iPhone, iPad and iPod touch on file before Apple releases the next firmware.
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.
