I found solution my problem.

Default value for parameter static.auto_provision.attempt_expired_time is 5 seconds. But on 100 Mbps ethernet phone can download 7565456 bytes, but size of new rom is 7565584 bytes and phone can't correct download new rom file for normal update. If increase static.auto_provision.attempt_expired_time to 6 or more seconds you can updating done.
