Hello guys,
I was working these days with nRF9160-DK board without any problem. Was able to update the firmware on it, to use it as a programmer for Thingy:91 etc...
I don't know what exactly I did this morning but the board is suddenly invisible for my PC! It seems that the issue is with onboard bootloader. Is there any way to recover onboard bootloader on nRF9160-DK? I know something similar is possible to do with nRF52840-DK, for example (link).
Thanks for your time and efforts.
Sincerely,
Bojan.
