copy tftp: <tftpserveripaddress> <filename> system partition 1 <filename>

you will need to copy it onto the partition which is not the current boot partition - either 1 or 0. The device will automatically boot from the partition you just copied it onto with the new OS.

Show boot command will tell you which is the current boot partition.
