Wrong. Sane models have will attempt to boot off TFTP for a few seconds every boot. Even if you brick it, you can install a new image via TFTP. This is how I do *all* installs, because it's less aggravating than dealing with some "upload new firmware" page of the vendor OS.
This works as long as it's hard to overwrite or corrupt the code executed on boot that performs the tftp. A good design would isolate that from the flash which holds the OS.
