Hello, I just got my kit for a corne 6 column layout. After putting it all together , I tried flashing the firmware, but I could only get the right half to flash. The left haft does nothing when plugged into the computer. I pulled the nice!nano out of the left half and tried plugging it into my computer by itself and notice that none of the LED on the board turn on even for a second and my computer did not recognize anything being connected. Compared to the right half were after flashing the ZMK firmware, the blue and red LED flash for a sec before turning off and my computer detects that a USB device has been connected after I hit the reset button. On the left half, I have tired hitting the reset button twice and manually resetting it by shorting GND and RST, but nothing changes. I have double check my solder joins and confirmed nothing is getting shorted out on the nice!nano. My question, is my left half nice!nano dead or will re-flashing the boot loader fix the issue like seen in the troubleshooting guild here? - https://nicekeyboards.com/docs/nice-nano/troubleshooting/#my-nicenano-seems-to-be-acting-up-and-i-want-to-re-flash-the-bootloader
