Feb 21, 2016 5:46 PM in response to deez126by Lawrence Finch,There is a slipstream update to the iPhone that fixes Error 53. It is a later version than 9.2.1, but is still called 9.2.1 (but a different build number). It can only be installed through iTunes, because it changes a security setting for Touch ID, and, as a security measure, the phone cannot update its security settings itself.

- If you'd like to find out if you're running iOS 9.2.1 please check out this support Article from Apple:
- If you need help updating your iOS device, I recommend this support article from Apple as well:
I understand the importance of keeping your iPhone safe from viruses or malware. Rest assured, you don't have to worry about viruses getting onto your iPhone. In fact Apple gives developers "top notch APIs, encryption, app transport security, trusted boot and sandboxing, and kernel address space layout randomization" which are all features that help keep it safe and secure from viruses, or malware.
The safest place to install iTunes is from here: http://www.apple.com/itunes/.
If you're already doing things like adding a passcode to your iPhone, or keeping your iOS version up to date you're already on the path to keeping your iOS device secure. Apple considers "malware" to iPhones as "strangers" because of the many features Apple provides it's developers to keep iOS secure.
I hope this helps you,
John
