Hmm...
So create a file of 512 bytes of zeros (or as few as one) as that name.
The dumb software will 'continue' to append the OTA file to it.
Which of course will fail to install because the signed checksum will fail.

That will leave you with a nice copy of the OTA file (which you will probably have to un-delete from USB storage) once you trim your dummy header off of it.
