I have a happymodel ep1 receiver and when I boot it it is just a solid green light, I have tried a different uart and also tried to switch the rx and tx port, and I tried to put a 1k ohm resistor on the rx pad. But this all doesn't work.

Has it worked previously? What happens if you only connect power?

You'll likely need to do a recovery flash:

Follow these steps to recover a bricked RX:

- Move the 5v wire going to the receiver to a 5V pad that only powers on when a LiPo is connected 
- Disable Telemetry in Betaflight
- Save and Reboot
- Close Betaflight Configurator and unplug USB and LiPo
- Bridge the boot pads or hold down the boot button on the receiver
- Plug in USB
- Click "Build and Flash" in the ExpressLRS Configurator, selecting via Betaflight Passthrough method
- Wait for the line PASSTHROUGH DONE to appear
- Plug in LiPo (with boot button held down/bridged)
- Wait for the process to finish (with success hopefully)
- Unplug everything, unbridge the boot pads, then power on to confirm the LED blinks, and then goes into WiFi mode
