Maybe this wiki page can give a guideline for the ISO creation step:
  https://wiki.debian.org/RepackBootableISO
especially with an older Live ISO:

If the old ISO does not have an MBR for booting from USB stick, then one
may dare to use Debian's
  /usr/lib/ISOLINUX/isohdpfx.bin
It might be that the ISOLINUX stuff of the old ISO does not work with the
current MBR, though. Then it would be necessary to to replace the ISOLINUX
bootloader "isolinux.bin" of the ISO by the neighbor of above MBR file
  /usr/lib/ISOLINUX/isolinux.bin


Have a nice day :)
