What's the matter with IOS 11.3.1 failing to downgrade? What's the content updated in IOS 11.3.1
Four seas network: Apple pushed the update of IOS 11.3.1 not long ago. Many users said that they could not be downgraded after the upgrade. What's the matter? What has IOS 11.3.1 updated? Come and have a look.
Today, apple quietly closed the system verification channel of IOS 11.3, only a week after the previous release of IOS 11.3.1, so users upgrading to the latest version should wait for the official version of IOS 11.4 to be updated.
In fact, the main problem of IOS 11.3.1 previously released is that those third-party iPhone 8 screens can't be updated by Apple due to the touch update of the screen, so they can't be used after changing the screen, and this small version update is to solve this problem.
At present, IOS 11.4 has been pushed to the third beta, so from this speed, the official version of IOS 11 should soon meet us, and this should be the last system version that can be updated in IOS 11.
Let's look forward to it.
