Need Help

I am trying to load firmware on the TTDS card. I went to the website suggested to me previously (http://www.linfoxdomain.com/nintendo/ds/) but have been unsuccessful. I downloaded the first firmware link: DSTTi_v1.4_firmware.rar 6.49 MB, then extracted it and copied it to the TTDS. But it did not work. So I downloaded the next link: DSTT_Menu_v1.17_English.zip 1.19 MB, then extracted it and copied it to the TTDS. But it still did not work.
Am I possibly downloading the wrong thing? Am I doing something wrong?
Please help!

The v1.4 firmware is the DSi 1.4 firmware bypass upgrade for the TTDS.1.17 should work just fine, make sure you take the files and folders out of the "English" or "Eng" or "en" folder. They have to be on the root of your card, if they are in a folder (which they are in when you extract them) you have to take them out of the folder.1.17a12 is a better firmware though.
