Definition - What does iPhone Recovery mean?
Techopedia explains iPhone Recovery
Typically, iPhone recovery requires the user to connect the iPhone to a computer with iTunes installed and a valid account on iTunes. More importantly, it requires that the user has created an iPhone backup onto a computer or iCloud.
Once connected, the user can select and restore the iPhone from available backups.
Recovery problems that are due to hardware defects must be manually corrected by repairing or replacing faulty parts.
