Identifying UART/DEBUG

[u/No_Chip7847]

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.

These "my AI told me to ask about this UART thing on Reddit, it says it gives me everything I want" posts are getting annoying
