Photon Corrupted Bootloader

Thanks. I found that page, unfortunately I am a software guy, not hardware. I found this post (Electron Wont boot up) which specified which pins to connect to. I looked at an st-link v2 and they come with manufactured cables to plug into a board. since the particle doesn’t have that kind of interface, do I need to build my own with an st-link compatible plug on one end and wires to plug in the bread board on the other? If so do, I use the SWIM connection?

I’m willing to do the leg-work on this but I’m trying to figure out where to start.
