@fanoush The answer was: I fried something. I reflashed original FW and UICR and can see the HR lights activate to verify it's running (the screen was damaged while opening), but still no signal on nrfConnect.
Update: I have a 2nd one.. just flashed that with the Espruino build, and it's perfect. So, issue resolved.
