To reset the iPhone from your computer, you must install the iTunes program on your computer (if you have not already) that the iPhone management program. iTunes you can download for PC and Mac from the Apple site. If already installed, check that it is the latest version from the menu that appears by clicking the question mark on the top bar.

Alternatively, you can follow the guide to make the backup of the iPhone using iCloud. The backup allows you to save photos, apps, contacts, settings and other data so that you can automatically reset after the reset and return to use the iPhone as before. 2) Reset the iPhone Once the backup is complete, you can click on the gray button to restore the iPhone appearing in the Summary tab in iTunes. Accept and confirm the decision and, if required, accept the software license agreement that will initiate the download of iOS before recovery. 3) Restore Data Once the phone has been reset, turn it on and check that everything is empty, with the only pre-installed applications from Apple, no account and no data in memory. If done correctly, it will meet, at power of the iPhone, the startup wizard, from which you can restore data from a backup or continue as if you had a new phone just came out from the factory or store. Restoring data it can also be done from iTunes by choosing the last backup made. You can also reset an iPhone from the same phone, without using iTunes and a computer.
