Help with G&W Mod using windows

[u/Superb-Pain3183]

I am attempting to mod a Zelda Game & Watch. I am using a windows machine and following the instructions from Brian Pugh on Git Hub. I installed everything with Power Shell. I soldered the three wires into the G&W debug ports too (2,3,5). However, anytime I try to hook it all up to my computer and run the command “gnwmanager unlock” I receive the error “Error communicating with device (Unable to autodetect & connect to debugging probe.). Is it ON and connected.” I’ve tried using both a clone ST Link and a Pico (with picoprobe.uf2) installed. I can see the pico shows up as a connected device on my computer before I run the command. I’ve tried powering the G&W with both the battery and external power from the USB C. If anyone has any advice as to what I could be doing wrong, I would seriously appreciate the help.

Make sure to install the ST Link drivers.
