bricked Thingy91 unable to put DFU mode nrf9160

user115969

Hi there,
i have a thingy91 for the electromaker contest. 
I've flashed the nrf51 bridge firmware using MCUboot. All went well.
However, when i try to put in DFU mode the nrf9160 nothing happens and no com port is detected in MCUboot.
Why does that happens ? and how can i flash the firmware into nrf9160 ?

thank you

    Hello, 

    What version of the Thingy:91 are you using? This is visible on the sticker inside located on the PCB.

    I've flashed the nrf51 bridge firmware using MCUboot

    What firmware are you referring to? How did you program this? 

    However, when i try to put in DFU mode the nrf9160 nothing happens and no com port is detected in MCUboot.

    How are you doing this? 


    Please provide more information for us to reproduce this issue.

    Thanks.

    Kind regards,
    Øyvind
