Hello! I have a turnigy 9xr Pro, which I recently upgraded to Opentx v2.2.2 . I also got a frsky r9m and r9 receiver and need to get about updating their firmware too. I placed the .frk firmware files in the firmware folder of the sd card but when i go to the sd card menu (page 2 of radio setup) and navigate to the firmware file and select it, I only get the options to rename, delete etc and nothing to do with flashing (no flash internal/ extenal / s port device options to select). I did some research but nothing worked. Help would be very apreciated. Thanks!
