iPhone Error 9
It is noted that the iTunes 9 error is less common and as common as other errors such as 3149, 4013, 4014, 3600, etc. The problem, however, is that when he hits, he hits hard enough. The time he "hits" is mainly the update or restore of your iOS device. When this happens, all your progress is lost and your iOS device (iPhone X, iPhone8 / 7/6/5, iPad, iPod) will actually be stuck in one of two options.
Here are some of the symptoms and prompts you may have encountered.
- The iPhone or iOS device has expired when synchronizing with iTunes.
- A pop-up window indicating that an unknown error occurred during the synchronization process appears.
- You have clearly received the iTunes 9 error or also an error with the numbers 2001-2011 during updates or restorations.
- You will notice that your iOS device can not operate at full capacity because it requires more power.
- You will also notice that your iOS device actually works faster when you switch to a higher level USB port, such as 2.0 to 3.0.
The usual causes of error on most devices are related to software problems. The problem is that the hardware, regardless of its strength, also contributes to the loss of functionality of your iOS device. Here are the common causes of this error.
- Your iOS device is jailbroken.
- Security software on your computer causes communication hangs between you and the Apple update servers.
- Your firewall on Windows or Mac blocks communication between you and Apple servers.
- There was a misconfiguration of the network or it was corrupted in one way or another.
- In conjunction with 4th cause - It is known that your own computer has hacked or jailbroken another iOS device, which caused confusion in the recognition of the device.
- The USB cable has caused an interruption in the update or restore process.
Method 1: Check the USB port and connector
The iTunes 9 error may appear if there is an accidental disconnection between the device and the computer during the data transfer process. Follow the steps below to check your USB connection in the following ways:
1. Use the USB cable that came with your device. If you do not have it, try another Apple USB cable.
2. Switch to another USB port on your computer. Do not connect your keyboard.
3. Try to connect to another computer.
Method 2: Check Anti-Virus and Firewall
When you try to upgrade your iPhone / iPad, iTunes connects to Apple, checks for hashes, security keys, and more. If, during the attempt, iTunes can not connect to the Apple servers, it generates an error such as the iTunes 9 error.
Ensure that all virtualization applications such as Parallels or VMWare are closed, as they may interrupt the ability of the computer to communicate over USB, especially if they are not configured correctly or are out of date.
Method 3: Hard Reset Your iPhone/iPad
The iTunes 9 error related to a software problem such as a software crash can be resolved by this method. The steps are slightly different between the iPhone models.
- On iPhone 8 / X / XR / XS: Press and release the volume up and down button. Then press and hold the side button until the Apple logo appears.
- On an iPhone 7 or iPhone 7 Plus: Press and hold the Side and Volume Down buttons for at least 10 seconds until the Apple logo appears.
- On an iPhone 6s and earlier, an iPad or iPod touch: Press and hold the Home and Power / Standby buttons for at least 10 seconds until the Apple logo appears.
Method 4: Update iTunes to the latest version
Check if the latest version of iTunes is installed on the Mac or another computer. Otherwise, update iTunes with the latest version.
