I found an old ep2 in my stash and hooked it up to my goku f411 fc. I was able to update successfully via wifi to 3.2.0. Would not bind to my TX troubleshooting ensues. So, when plugged in, the ep2 immediately starts fast blinking like its in wifi mode but the ssid does not appear on my pc. Seems it's stuck on fast blinking. I soldered the boot pads and the light stays solid green but I cannot flash anything to it. I removed the solder on the boot pads and still blinking fast. Any ideas? TIA

Reflash via Passthrough or 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

When I try to build and flash via passthrough I get " could not open COM8, the port does not exist". Betaflight is connected on this port should I disconnect or close BF?

#

Boot pads soldered, when doing this?

Yes, BF must be disconnected

#

Two programs can't use the same com port at the same time

FIXED! Thank you V-22... I was caught by the part where "PLUG IN THE LIPO" when passthough done appears.
