Due to recent changes, i.e. OTA loader into the FW ToH HoT.
The developers of the tool - nostromo and CrazySat - made a little modification to the rdd file to let the program recognise the OTA module as known.
In a few words just copy and paste the default.rdd file into the folder of HDFSmart.
In this way if you open the latest ToH/HoT FW, with database updated you will see that all modules are flagged with a green "very good" sign. So completely original.
Thank a lot to CrazySat, nostromo, humax-zone.net and ToH HoT Team.
Thanks to our friend Carnage for the clear explantion.
