Solved Unbrick an ELRS Rx

[Merv]

I updated my ELRS Rx & disconnected it too soon, before the light began blinking after an update. As a result, the Rx was bricked, when you powered it on, the light would immediately go solid, like it was connected to the Tx, except is was not connected. No matter how long you left it, it would not go into Wi-Fi mode. The Rx would not respond. I was able to unbrick it with the instructions in JB's video below. In my case, the particulars were slightly different. First my Rx was as PWM receiver, a Happy Model EP1/EP2 2.4GHz Rx. I used a generic FTDI adapter that I already had on hand. My PC had to update my drivers & reboot before it recognized the adapter. In my case the Ch2 signal pin was the Tx pin & Ch3 Rx, the positive on any positive pin and negative on any negative pin. A bind plug on Ch1 to put the Rx in boot mode. After connecting the FTDI adapter, I was able to flash it using the ExpressLRS configurator, using the Betaflight Passthrough option. Now it's time to fly.

Nice! Bardwell is one of the best on the choobs!

The nice thing about modern hardware is it is MUCH harder to actually brick something to the point it can't be recovered. Newer hardware can be fixed with the RX/TX pads where older hardware required connection directly to the processor on the board. I have a handful of boards where the recovery required soldering directly to the processor pins. Some, small pads on the board, and both required a specialized adapter rather than serial passthrough or an ftdi adapter. Progress is great! But I still fly some seriously old school too! i refuse to let old hardware die! (up to a point)

Cheers!
