Do you have enough free space? If the phone has 8.2, the delta installer measures ~300MB and will need 2-3 that amount to uncompress, verify and install. If the phone has an older version than 8.2, the full installer is needed and that is much bigger, over 1GB, and you should have at least 5GB free to avoid problems. If you update via iTunes on a computer, those space requirements are drastically reduced since the installer is stored, verified and uncompressed in the computer and not the phone.
