Current version is 2.5.1
Using ExpressLRS configurator in betaflight passthrough model
Error Wrong target selected your RX is 'HAPPYMODEL_EP_2400_RX', trying to flash 'UNIFIED_ESP8285_2400_RX'
But this target name not in pulldown menu
Have been using HappyModel EP1/2 2.4GHz RX which is the only obvious fit to my Rx

PS Looks like ExpressLRS configurator is loading the wrong file. I can't find the right file on HappyModel website or Github. I'm a complete novice with Github I'd welcome any tips on getting the right file which I think I can use to flash the EP1 using my 'phone.

Just flash that unified target with the latest configurator. Works fine here.

Hit flash anyway.

I was having this same issue, try flashing trough WiFi instead of doing the betaflight passtrough. It worked for me that way last night.

Hi Seeker - I would use the WiFi method except that I can't find the right file. I downloaded a file from the Happymodel website but that was just a few kB - unrealistically small and the 'phone app said it was incompatible. Perhaps the right file is on Github somewhere but I couldn't find it there either. Bas I might try flashing with the wrong file - I hope it doesn't brick it.

How big in size is the firmware file that you generated yourself in the ELRS Configurator?
