Just tried updating the firmware. Lights blink on my UART board however it said failed.

Connected GP23 to GND like I did originally to update the firmware.
Rather odd as I took precautions to make sure I used only the 3v3 UART however like explained It was just plugged in normally when it stopped working. Odd!
I'll return it to the retailer and request a replacement as I was rather enjoying it.
