IWR6843ISK: How do I flash the demo ("Initial response from the device was not received")

I'm sure this will turn out to be some basic error - but I've been trying for a few hours and can't figure out how to flash the demo software to my IWR6843ISK device. Here's what I've done:

  1. Installed the mmwave SDK and UniFlash
  2. Connected the IWR6843ISK to the MMWAVEICBOOST board
  3. Ensured there are jumpers on the SOP0 and SOP2 pins (the board also came with jumpers across some other pins - I've left them as-is)
  4. Connected the USB micro-B port on the IWR6843ISK to my computer
  5. After that, I've tried connecting another USB micro-B cord from my computer to the "FTDI-USB" port on the MMWAVEICBOOST and just connecting the 2.1mm power jack without connecting the MMWAVEICBOOST to my computer
  6. I pull up the device manager on Windows, but instead of seeing a port labelled "XDS110 Class Application/User UART", I see "Silicon Labs Dual CP2105 USB to UART Bridge: Enhanced COM Port (COM4)".
  7. Open UniFlash, go to "Settings and Utilities", enter "COM4" as my port.
  8. Go back into "Program" in UniFlash, and for Meta Image 1, select <sdk folder>\packages\ti\demo\xwr68xx\mmw\xwr68xx_mmw_demo.bin
  9. Hit "Load Image"

The result is that it hangs for a minute on "Opening COM port COM4", then tells me "Image Loading Failed: Unable to Connect to Serial Port". In the log, it says "Initial response from the device was not received. Please power cycle device before re-flashing". So I've tried unplugging/re-plugging, hitting the SW2/RESET switch on the MMWAVEICBOOST at various times during this process - same outcome. Can anyone tell me where I'm going wrong?
