The Risks of Downgrading iOS

You aren’t really thinking to downgrade the iOS version of your iDevice back to the previous one, do you? Well in that case, please stop right there! We recommend you to gain some quality information about risks of downgrading iOS prior to performing the downgrade. We don’t want to scare you but it is necessary to be aware of the consequences or mishappening that can take place after downgrading iOS.

#1. Unlike Upgrade where all your data stays intact, downgrading iOS wipes off all your data on your iPhone, i.e. messages, contacts, photos and everything else will be deleted permanently.

#2. Make sure that you already have iPhone backup of your previous iOS version to which you are downgrading your iOS version to. For instance, you upgraded your device to iOS 11 and now downgrading your iOS version back to iOS 10. In that case, you won’t be able to restore an iOS 11 backup to your downgraded iOS 10 version. You must have an iOS 10 backup file with you to enable you to restore data from.

#3. Users who have downgraded iOS version of their iDevice have reported that their iDevice has become unresponsive after downgrading iOS to the previous version.

#4. However, we at our office also attempted to downgrade an iPhone 8 from iOS 11 to iOS 10 and eventually, we were left with nothing but a phone that wouldn’t turn on. Although, this was a very rare occurrence but we must stressfully mention it here to make you aware about every possible risk involved in downgrading your iOS version.
