This happens with normal application file upgrades. Having processed the upgrade script file, the software determines that the name of the boot file in the phone is the correct version. It next determines that the name of the application file does not match that stored in the phone.
The phone displays the required file name as it downloads the file from the TFTP server. It also displays the number of kilobytes downloaded.
Saving to flash is displayed. The phone also displays the percentage of file stored and the number of seconds that have elapsed. This will usually take longer than it took to download the file.
The phone is reset so that the new system-specific application file can be executed.
