this is the name of the file that i downloaded in the website: ftrfb_main_03_65VDFC.ftd, so i will rename it to FTRFB.FTD...

now i will be redoing the firmware, i wii just be powering the vdip by its ground and vcc pins and i dont need to connect anything to the vdip yet right? how do i know if the firmware had already been installed?
