Restore Portenta to factory firmware

I have a Portenta H7 ABX00042 installed into the breakout board ASX00031.
I connected a USB C cable to the Portenta for power. The Portenta has a orange LED that is solid and blinks once every 15 seconds. Pressing the reset button - double tapping the reset and power off and on has no effect. I have connected an STLINK-V2 to the JTAG connector on the breakout board. I am unable to connect using the STM32CubeProgrammer - No STM32 target found!
