The first thing you’ll want to do is go into Cydia and install Cydia Impactor, which can be found by searching for it and typing in “Cydia Impactor.” From there, tap to view the tool and then tap on Modify in the top-right corner. Then select Install from the pop-up that appears.

Once you have it installed and are ready to unjailbreak, be sure to back up your iOS device and then turn off Find My iPhone by going into Settings > iCloud > Find My iPhone. You’ll want to backup so that if something goes wrong during the unjailbreaking process, you won’t lose any of your precious data, including any saved settings, as well as photos, music, etc.

Now, fire up the Cydia Impactor app and you’ll be greeted with a handful of things that you should know before you continue on, some of which I already mentioned, but it’s a good idea to give the list a good look-over. After that, simply tap on Delete all data, unjailbreak device to start the process, and then tap Delete All to confirm.

Just sit back and relax as the tool does its thing. It could take up to twenty minutes to complete the process, depending on how much data you had stored on your device (a 128GB full of data will take longer than a 16GB device), so be patient. Once the process is done, you’ll be greeted with the iOS Setup Assistant that you might be familiar with when you first set up your iPhone when you bought it, giving you the infamous Hello greeting.
