Hi,
I received a Thingy91 from a colleague who orderd it shortly after hitting the virtual stores but didn't do a lot with it.
I got it on my table and started to work on it, connecting power but not a single sign of life. No led activity anywhere.
Connecting it to USB shows two USB ports in Windows 10 but again no life, not in nRF connect with AT commands, nothing.
Got hold of a J-link Base and connected to the thingy and got some respons of it but now I need to know how to restore everyhting. I suspect it is completely empty and would like to know how to restore the Thingy 91 fully so i can get started with the asset tracking example. For this I have installed SEGGER according to the instructions.
I am pretty new to this enviroment and the j-link so be kind ;).
