I've been having major issues with this new X20RS radio. Received Radio with Ethos 1.6.2 which has now been updated to 1.6.4. When copying Mike Shellim's e-soar maxx template esm211.bin to the SD Card the file does not register to a new model. Does not read from the card. I've also copied the radio.bin file to the card and renamed it firmware.bin with no success. There is nowhere within the 475 page ethos manual that tells us to do that; however many web searches say that it is required for radio to read from the card. Any suggestion's
