With more than 200 million users who already upgraded to iOS 7, Apple’s latest firmware has gained a lot of popularity. However, despite its amazing features and innovative options, the firmware might turn out to be a little too demanding for older devices.
As you already know, iOS 7 is not compatible with older devices such as iPhone 3GS and even iPhone 4. In the case of the latest device, the firmware is compatible, but it does not provide the same features and the same performance.
Much like iOS 6 on the iPhone 3GS, the iPhone 4 tries to offer the smooth, streamlined experience offered by the iOS 7. However, those who are running the 2010 handset, might find things to run a little bit lazy than before. In this case, the proper solution would be to restore to the previous firmware, the one that offered the best user experience.
For this action, users will need to have their SHSH blobs saved in the past in order to start this process. Without it, there is no other alternative than remaining with iOS 7 on iPhone 4.
On the other hand, for these who thought about saving the SHSH blobs while Apple was still signing for the respective firmware, there is some good news. They will still have the possibility to downgrade from iOS 7 to iOS 6.x.x using the following step-by-step guide. The tutorial was intended for Windows users, and it works only for the iPhone 4 running Apple’s latest firmware.
1. As some users already upgraded to iOS 11.1.x, the process required an older version such as 11.0.5. In case you already upgraded to iTunes 11.1, before starting the downgrading process, you need to uninstall iTunes. This is because Apple already stopped signing for iOS from iTunes 11.1. In the same time, services such as Apple Mobile Device or Apple Software Updated need to be uninstalled, as well.
2. Secondly, users will have to install iTunes 11.0.5.
3. For the next step, users will have to download iFaith 1.5.9, as well as to download iOS 6.1.2 or to download iOS 6.1.3. This depends on the firmware users have saved blobs to downgrade to. Fortunately, iFaith helps users locate saved SHSH blobs easily, even if they are stored within Cydia Store.
4. After launching iFaith, click on “Build “*signed* IPSW w / Blobs”. This will start the downgrading process for the desired firmware.
5. Next, locate the SHSH and select the stock iOS firmware downloaded before. At this point, the program will start creating a custom IPSW.
6. Follow the instructions on the screen and put your device in DFU mode, using iFaith’s built-in DFU Pwner. For those who do not know, just hold Power and Home button at the same time for about 10 seconds. Release the Power button while holding the Home button until the screen is black.
7. In the last part, load iTunes, select your iPhone, hold the Shift key and click on Restore iPhone. Browse for the firmware created by iFaith. Now, the iPhone 4 will be running on iOS 6.1.2 or iOS 6.1.3.
