For other beginners like me, SN of Jlink debugger works fine.

Please close this case.

Hello Hakon,

Thanks for the clarification.

I am trying to program mfw_nrf91x1_2.0.2 to the module using:

nrfutil 91 modem-firmware-upgrade --firmware <PATH> --verify --serial-number <SN>

As for the serial number, neither the one on the chip nor what I receive from +CGSN doesn't work.

Can you advise how to get the valid SN?

Thanks

Hello,

No wonder non-PTI commands are not working, you have the PTI mfw flashed on your board.
