How to back up iPhone 4S before flashing it

Before reflashing the firmware, please use iFunBox or use iphone folders to connect to your XiaoI. After connecting, you will see all the directories in the phone. The files you want to back up are in the /private/var/mobile directory. In the related directories~~~

Under Library: AddressBook is the address book, SMS is the text message, Notes is the memo, Calendar is the calendar, Mail is the email, Safari is the favorites; [/size][/ color]

Under Media: DCIM refers to photos and screenshots taken by the camera, Photos refers to pictures synchronized from the computer, iTunes_Control refers to music, movies, and ringtone files; the path of call records is: /private/var/ wireless/Library/CallHistory/call_history.db

After backing up the above directories you need to back up on your computer, you can refresh the firmware. After refreshing the new firmware, you only need to back up the ones you just backed up. Just overwrite the existing directory with the directory. Check to see if your address book and text messages are back again, haha.

If you encounter some strange problems with the newly flashed firmware, such as photos that cannot be saved, memos that cannot be saved, etc., most of them are directory permission problems. Go to the corresponding directory above to change the permissions and try directly changing it to 777. One click should be enough.

Personal summary: Through the backup method mentioned above, you do not need to use iTunes to restore after flashing the new firmware. In iTunes, do not choose to restore from the data you backed up before, but choose a new one. equipment, so that you will feel that the system is cleaner.

Another point that needs to be emphasized is that this method can also solve the problem that some friends cannot access the Internet on 3G after flashing the firmware and restoring it with the original backup data.
