How to adapt ios6 and ios7

Now I will introduce the whole process of backing up, upgrading to iOS7 and restoring data. I hope it will be a reference for friends who want to upgrade. Since my mobile phone is iOS6.1.2, I will take this system as an example first. Jailbroken iOS5 and 6 can also refer to the following tutorials to upgrade to iOS7

Preparations for upgrading to iOS7 from jailbroken iPhone 4s :

1. Upgrade to iTunes version 11.1.

2. Connect the iPhone to the computer and open iTunes. In the Backup section, select "This PC" and then click the "Back up now" button. The system will automatically back up the photos, contacts, applications and other data in the iPhone to the computer. Then perform the "synchronization" work of the application. However, only genuine APPs can be backed up here. Cracked APPs installed during jailbreak will not be backed up and restored.

3. Download the official version of Ios7. (Click to download the firmware), please choose the version suitable for your device, don’t choose the wrong one!

Tutorial for upgrading jailbroken iphone4s to ios7:

1. Enter the iPhone into DUF mode. Because DFU mode is a recovery mode before the iPhone firmware is booted, this upgrade method is relatively clean and safe. Before, there was a method on the Internet to flash the iPhone to a non-jailbroken version and then upgrade to ios7. This method has certain risks and requires one more step.

Operation method:

a. Turn off the iPhone;

b. Press and hold the Home button and the Power button (power button) at the same time;

c. At this time, the white Apple LOGO will appear. Do not release the two buttons. Wait for about 10 seconds and the iPhone screen will go black;

d. At this time, continue to hold the Home button and release it. Power key until a dialog box appears on the computer screen saying "iTunes has detected an iPhone in recovery mode. You must first restore this iPhone from a backup before using it with iTunes."

e. Click the "OK" button;

2. Start upgrading the ios7 firmware. Press and hold the Option key (Shift key under Windows) on your computer and click the "Restore iPhone..." button with your mouse. Then select the downloaded iOS firmware file (suffix name is .ipsw).

3. iTunes will pop up a dialog box "iTunes will erase the iPhone and restore it to iOS 7.0, and will also verify this restore with Apple.", click the "Restore" button to continue.

4. Upgrading... There is basically no need to do anything at this time, all you have to do is wait.

5. When you wait to see the welcome interface of iOS7, it means that the work is basically done! Multiple language versions of the "Hello Slide to Settings" switching interface will appear on the iPhone interface. Swipe to enter the settings interface, step by step, don't go too fast.

6. When you get to the "Set up iPhone" interface, remember to select "Restore from iTunes Backup"! At this time, the iPhone will connect to iTunes on the computer and restore the content just backed up to the iPhone (mainly call records, address books, and text messages).

7. Recovery comes later, that is, waiting and waiting. After the upgrade is successful, the system will pop up the "Software Update" dialog box, prompting that you can upgrade to iOS 7.0.2. It is strongly recommended to upgrade! Then just do it step by step.

How about it? It’s easy and safe to follow these steps to upgrade an iPhone 4s that has jailbroken iOS 6.1.2 to IOS 7, right?
