the problem often lies within the user's end, but still most Apple fans get an iPhone for the hassle free experience which is less common on Android; and such errors do really hurt the Apple reputation. However, iTunes error 21 often shows up while an iPhone or iPad iOS update is attempted using iTunes. The problems don't have any specific one-button fix, thus users will have to take the hit & miss path to test each and every possible solutions to succeed. Here are seven easy fixes which are most likely going to work and fix iTunes error 21. How to Fix iTunes Unknown Error 21 Below are posted the top 7 methods to fix iTunes error 21 when you restore or update your iPhone: 1. Restart iTunes iTunes isn't very perfect even till yet, it often tends to act very buggy. iTunes error 21 could be a result of a faulty session. There could be other reasons like a disrupted connection between the iPhone and iTunes in midst of the update which resulted into a temporary corruption of update files, potentially leading into unknown error 21. Other similar sort of issues might just arise in a matter of moments. Restarting iTunes is the best possible solution in such cases; as it resets some values and bits underneath to bring things back to normal. 2. Update iTunes Is your iTunes the latest version from Apple? With update in iOS and every other software, iTunes needs to be updated as well. Especially if your iPhone is running the latest iOS and your iTunes is few generations older - many errors like error 21 are very likely to appear every now and then. There are probably a lot of conflicts happening underneath triggering errors. 3. Disable Antivirus for a While Updates require internet access. Though it's very unlikely to happen, yet your security program could list iTunes as a malicious program and block all incoming and outgoing data traffic through this app. As a result, updating iPhone via iTunes will be interrupted. Check your antivirus block list for such case, or simply disable it for a while. 4. Check Host File Check if the .hosts file doesn't block the Apple's servers. To do that you need to open your hosts file. Check this guide if you are a Mac user & check this guide if you are a Windows user. 5. Unplug USB Devices you Don't Need Unplug every USB device from your computer that you don't need, especially other smartphones or storage drives. Those devices could create conflict and make iTunes unable to detect an iPhone. There could be issues like difficulty in voltage management in older computers with very old motherboards. Unplugging USB devices might speed up things a little bit. 6. Sensor Cable Modific
