I give up. Tried everything but change from 3.3v to 5v VDD. I am so tired of this board. I would love to see a video of it working, cause I hardly believe this is working anywhere but Italy dude. Have been 3 nights and nothing. Could at least, If you don't mind, upload a video or photo? I mean, It will be useful to check the busy led and the behavior.
Just to be clear, you changed from 3.3v to 5v, and you are NOT using any resistor for pin rst, dta or clk right? It is the only thing that remains to change in my configuration to give up definitely. It is so frustrating.
