Thingy

[Bill.Bracken]

Was going through the process of updating the modem and application on my just purchased Thingy-91.  Initially the programmer reported that the processor and two serial ports were present.  I pressed SW3 when powering on the device.  When I selected update modem (enable MCUBoot was selected) it appear to complete the first step of processing the file but then indicated that the mcu boot wasn't active.  Now I don't even see a device to select and with the usb not plugged in the Thingy doesn't function.

Not sure what I did and am a bit concerned that it was this easy to brick the Thingy.

Thanks,

Hi,

 

Now I don't even see a device to select and with the usb not plugged in the Thingy doesn't function.

 Stupid question, just to be sure: Is the power switch in the ON position?

What HW version of the Thingy:91 do you have? It should say on the sticker, below the PCA number.

If you turn the Thingy on while holding the small white button next to the nRF9160 (SW4), are you able to set the nRF52840 in bootloader mode?

If so, please update the firmware of the nRF52840 to the newest version of the connectivity_bridge application.

If that does not work, you might be able to update the nRF52840 from a Linux computer or VM.

Could you try to follow this guide from a Linux computer or VM? https://devzone.nordicsemi.com/nordic/cellular-iot-guides/b/getting-started-cellular/posts/thingy91_2d00_fw_2d00_update_2d00_mcuboot

Note that the guide forgot to mention that you must also have Git installed for the 'go get' command to work.

Best regards,

Didrik
