Sorry for the late reply, I was quite busy.
Unfortunately I'm not the author of this project, nor have I built it. So I probably can't offer you much help.
According to the comments on the project page that resistor between pin 1 and ground doesn't need to be installed. Just leave the empty pads (DO NOT SHORT THEM!).
Compare your and original schematic once again, also check the PCB with the magnifying glass for short circuits between the tracks. Check the voltages.
Which firmware have you used?
You should try to reprogram MCU and verify flash first with latest firmware , and then with the older versions.

Regards
