How do I recover missing calendar data, contacts and photos after a re-sync?

[Android Central Question]

Before I did a factory reset on my ZTE N817 phone I sync'd the phone to my google (gmail?) account so my contacts, calendar appts and photos would not be lost. After the reset, I re-sync'd the phone but only got back about 10 % of my contacts and 1/3 of my photos and none of the calendar data. How do I get the missing data, contacts and photos back?

Only Google contacts sync - Phone, Device and SIM contacts don't, so you can't get them back. You'll have to enter them manually, but this time, pull down the top item and set it to your Google account.

Check your calendar at Google Calendar. That's what will sync to your phone.

As far as the photos go, I have no idea why they didn't all sync, but you have what you have - there's no way to get the missing ones back. (maybe this will teach you to keep a backup of anything important on a cloud account and, if you have one, a PC.)
