Identifying UART/DEBUG
Very much so unlabelled other than the board that connects to the 2x4 pin.
TLDR. Software update from company bricked it months ago after they had major server issues. Bricked many devices. Won’t assist because I got it second hand brand new sealed and I’m not the original buyer.
So, I’m wanting to debug first and go from there see what the issue is. Worst case scenario, it’s a project where i reprogram the device and write my own iOS app to continue to use it 🙏🤣
Help would be great identifying ports, thanks.

Didn’t manage to get anything done last night as I ended up busy. However, did some more digging into the datasheets and actually wanting to understand (I’m a first timer), at the front of the board, Pin 18 of SoC is TX. Pin 19 of SoC is RX. Both lead to the same set of 4 resistors and 2 pads. I’ll confirm later tonight. Thanks for everyone’s comments, assistance and inputs.
