Failed to flash thingy91: Error when fetching device versions:

Hello,

Somehow my thingy91 is no longer working so I decided to flash it from the beginning.

I put it in MCUboot mode ( holding SW4 and turning on the device)

in Programmer v3.0.3 I see the Thing91 and connect to it and then get the following error

Error when fetching device versions: readFwInfo error (Origin: "Error when starting nrfdl_fw_read_info")

Then the Programmer tool doesn't give me the right to write.

How could I fix this issue ?

I have nrf9160 dk that is working OK, and would use it to flash the thingy if needed but I can't find a full guide for that.

Please advice

  • Hi,

    Could you please enable "Verbose logging" and send us verbose log?
    You can enable verbose logging by opening Programmer Application, select "Verbose Logging" and "Restart with verbose logging".
