Hi Bro
As you've mentioned I tried both Mega & Uno with reduced 50 LED sketches & tried 115200, 460800 & 500000 Buadrates but had no luck so I guess there is nothing left for me to try but to move to APA102 & scrap these LEDs such a shame
Thanks again for all your help really appreciate it
Below are the sketches I used for your info
