FrSky X4R-sb no bind devo10 cc2500

Hello
I have a "Devo10" Radio Module with me "CC2500" it works well with the other receiver FrSky but with my "FrSky X4R-sb" I can not have the Binder.
I press the button FS I plug my battery LED green and red lights, but no moment it flashes
I watch the video for the bind I think that this is a problem of manupulation but has a firmware problem.
what firmware should install it for this evening compatible with the CC2500 module?
it is possible to flash my "FrSky X4R-sb" with FTDI? and how to thank you for your help

You need the FrskyX protocol for that receiver. It's available in the nightly builds.

The receiver must also have the non-EU firmware. Not sure how to flash these receivers.

ok thank you for the information using the protocol FrSkyX
I already tried like this may be it is already non-EU firmware because I bought that on Greabest Chinese.
