Thanks to the release of what Ian Beer calls async_exploit, it is increasingly possible to do things on Apple devices that were previously impossible without a full jailbreak. One last process involves the ability to change the text that appears on different parts of the lock screen.
The availability of exploits released means that developers can create new apps and experiences that allow functionality to be called previously only available to jailbroken device owners.
In this example, the focus is to be able to convert various strings on hard-coded devices into platforms, such as those found on the Lock screen when the device is locked. All you need to do that is a file explorer application created by using injected injections, like FilzaJailed we just told you. After you install FilzaJailed, you can follow the instructions below. Remember, this will only work on iOS 11.0-11.1.2 devices.
Of course, in a situation like this, his advice is always the same. If you do not know what you do or do not feel comfortable modifying these files and be wary of the results, then do not do that. It is not possible to change some string files to cause catastrophic effects but keep in mind that this is not a jailbreak luxury, and therefore, it does not have a Safe Mode Cydia Substrate safety net.
