There is good news if you have a PC, the iPhone 4 and you saved the SHSH blobs from iOS 6.1.3 or earlier, as you can go back to iOS 6.
However there is bad news if you have a different version of the iPhone and you have iOS 7 as you are stuck with it. This means that if you have the iPhone 5, iPhone 4S or iPad then you cannot go back.
It isn’t going to be easy going back if you have the iPhone 4 but it may be worthwhile if you cannot stand iOS 7. So if you want to go back just follow the guide outlined below.
You need to use iTunes 11.0.5 or lower for this to work. If you already have iTunes 11.1 or above, then you’ll have to completely uninstall it. You can download iTunes 11.0.5 from Old Apps.
Download iFaith from GitHub and unzip it.
Connect your iPhone 4 to your computer.
If you know where your “SHSH blob” is and you have it saved locally then you’re ready and you can skip to the next section, if not you can use iFaith to locate it. Double click the iFaith application and select OK then choose Show Available SHSH Caches on Server. Click Yes and then choose Show list of available SHSH blobs on TSS server(s). You’ll get a list of available blobs and you can download the one you want. When you’ve got it you can exit iFaith.
Using iFaith to downgrade to iOS 6
You should have your iPhone 4 still connected to your computer. Fire up iFaith again and this time select Build *signed* IPSW w/ blobs then Browse for SHSH blobs and select the one you want from wherever you saved it earlier.
You’ll need the iOS firmware file next, but you can just select Download it for me. Once it’s ready you can continue and choose Build IPSW. This will take a while, so grab a coffee.
When it’s done make sure to note the name of the IPSW file it has created and then click OK to continue.
You now need to put your iPhone into DFU mode. Hold the Sleep/Wake button on your iPhone and Slide to power off. Click Start on iFaith and follow the onscreen instructions to press and hold the Sleep/Wake key and the Home key for 10 seconds, then release the Sleep/Wake key and keep holding the Home key for 30 seconds.
You should see a message in iFaith telling you that your iPhone 4 is in DFU mode and you can click OK and then exit iFaith.
Restore from iTunes
It’s time to launch iTunes 11.0.5. It should detect your iPhone 4 in recovery mode. Click OK.
Hold down the Shift key and click the Restore iPhone … button in the Summary pane then browse to the IPSW file you created with iFaith and select it.
The restore will probably take a while, so just leave it alone until it is done.
You can now follow the instructions on screen to set up your iPhone 4 which should now have iOS 6 installed.
