We don’t wish it, but sometimes there comes a time where you have to take drastic measures. When something goes wrong with your iPhone there’s usually a fix, but if nothing works, you can always enter Recovery Mode on iPhone 11 or iPhone 11 Pro and fresh install iOS which can fix several issues. If you’re unfamiliar with the technique, we have devised some steps which will allow you to enter and exit Recovery Mode on your device.

If you’re a beta tester, public or a developer, you might already have come across the technique on the latest iPhone models. Beta builds aren’t stable and come jam-packed with bugs that hinder the normal working of an iPhone. Hence, Recovery Mode is used to recover your device from these scenarios.
