Does anyone knows where I can get OpenTX 2.2.1 or 2.2.2 firmware bin. I can’t get my iRange plux on my Taranis QX7 to bind with any of my FlySky receivers. I upgraded my Taranis to 2.2.3 to add the multi protocol but I didn’t backup the bin files. I’ve try every single sub-option under flysky protocol but none will bind, just get red blinking light. I have disabled the internal protocol and only enable the external. The dial is on “0” all I get is blinking red light.
Any guidance will be appreciated.
