3DR radio V1 Fails to Connect/Update

Hello.

I’m trying to update the firmware on the air module. I’ve connected it to an FTDI cable (see pictures), but when I try to connect with Mission Planner, I get a failed message.

I suspect I’m missing something on the connection(s). Can someone confirm the connections are correct, or if I’m missing one. The solder pads on the back of the module do not match exactly to the FTDI inputs.

Thanks!

Try to switch Rx and Tx.

Yep, I’ve already tried that. No change. I’ve seen some videos that suggest I need another connection. Just not sure what to connect.
