So I was gifted a Gs2 that needed a little work to get up and running, and as part of that I tried to upgrade it to Marlin. I used the SD software from this forum to remove the existong firmware, all went well. However, when I try to flash new firmware (again from this forum) the printer doesn't change after I turn it on.
As I said, it's a single extruder G2s using a GTMS2 pro mainboard.
I used the instructions here:

And the firmware from Number 11 on this page:

Any help is appreciated
