Yes, see how to do it below.
Step 1: Back up your data.
Before you start, if you have backed up before upgrading to iOS 9, or if you don't have important data on your phone, you don't need to back it up. If there is some important information on the phone, such as contacts, text messages, **, and there is no backup, it is recommended to back it up first.
In general, it is recommended to use the iTunes software on the computer to make a backup, which is more comprehensive, and the iTunes software will also be used when flashing the computer for a while, so if there is no one on the computer, please go to Apple's official website first**Install.
End the second step, go back to the iOS 8 system.
Next we need to go to the latest ios8 version on the Internet, the latest version is the current version, as shown in the picture. There are a lot of **iOS firmware provided** on the Internet, and I am here to take Weifeng.com as an example. In addition, when it comes to firmware, you also need the version corresponding to the iPhone, otherwise it won't work.
Once the firmware is ready, it's time to start downgrading iOS 9. First, connect your iPhone to your computer and open the iTunes software.
Then press and hold the power button on your iPhone, and when the shutdown option appears, slide to power off.
Then please follow the steps below to let the phone enter recovery mode: 1. Please press and hold the power button to turn on the phone, then the Apple logo will appear on the screen, do not release the power button; 2. Then press and hold the home button on the home screen until the screen goes black. 2. When the screen is black, please release the power button, and do not release the home button on the home screen until iTunes on the computer side appears and detects an iPhone in recovery mode.
Next, please click the "Restore iPhone" button in the window.
You'll then be prompted if you want to continue doing this, and if you do, all data on your iPhone will be erased. Click on the "Restore & Update" button and you're ready to go.
Then please be patient and wait for iTunes to extract the firmware and restore the iOS 8 system to your iPhone. When the downgrade is successful, you can activate the phone significantly.
