Hi there,

Could you go through step-by-step the Getting started with the Thingy:91 guide here. More specifically the steps preparing for setup and updating the Thingy:91 firmware steps.

regards

Jared

maybe it isnt the requested file?
it thought i did download the right file but it is possible im wrong. can you send me the right link to download.

in addition, now i notice that when i connect the thingy91 using a USB it and press the SW4 button. the port is recognized for a few seconds only and then disappear.

That's how to build and flash it! When you go to program it, you'll want to make sure the programming switch is set to NRF52 (rather than NRF91). That switch controls which CPU can be programmed and which ones logs you can see with the debugger interface (e.g. JLink RTT Viewer).
