The simplest way to install FFP-0.7 is to rename the ffp folder and copy the new fun_plug files to Volume_1. The steps to setup are similar to FFP-0.5.
BTW, there are 2 group of packages for 0.7, namely oarm for OABI-based devices like DNS-323 and arm for EABI-based devices like DNS-320. So remember to download the correct built.
