I forgot my password and my phone is disabled so I tried using an iMac updated to the latest gen to restore and update it and it didn’t work showing me “The iPhone “iPhone” could not be restored. An unknown error occurred (2015).” Also used a windows laptop. FYI, My battery level last checked was at 88% and it may be lower, does this change anything?
Hi bogbog, From what I have found, you can try, Updating iTunes to the newest versionMaking sure the iPhone is plugged directly into the computer and not through a hub or keyboardRestarting both your computer and your iPhoneChecking security software by updating, changing, or removing it.Retry the update or restore the iPhoneUsing a different device that has iTunes or is a Mac Source: Apple Discussions - Apple Support Thanks, Derek Thomas
Try putting the phone into dfu mode rather than restore mode.
