A family member has left me his iPhone 6 (he leave the country), so, because is an used iPhone, Do I need to have any information for restore it? I don't want to have problems with iCloud or nothing else. Please... any advice? Thanks!
This is what your friend needs to do to make iPhone work for you
What to do before selling or giving away your iPhone, iPad, or iPod touch - Apple Support
Once that is completed you can restore as new and start as new but not until it is completed
Restore usually means that you want to restore it with a backup from a previous iPhone. To do that see Transfer content from an iPhone, iPad, or iPod touch to a new device - Apple Support
If you just want to clear it and start as if it were new without installing a prior backup from another iPhone, see What to do before selling or giving away your iPhone, iPad, or iPod touch - Apple Support
What info I will need to restore an Used iPhone?
