Hello there! I am having problems to update the FrOs that came with my Horus X10s. I have tried everything that is out there in order to tell me how is done? With not much luck at all. The transmitter will not read the SD card with the firmware update. I can see on the radio screen the SD card but it doesn't seem to be doing anything else. I haven't been able to use this beautiful transmitter just because of this issue. My intention is to move up to Open TX but before of that I want to update the Os that came with the radio to the last version and safe the file for back up. I don't know if I am doing something wrong or if this is a warranty issue. Please any input will be totally appreciate. Thanks.
