I think originally that DLL was packaged with the Python module but that may have changed recently. I know other people in the community are having similar problems.

jaredwolff no joy, the same thing occurs
jaredwolff Hmm, I wonder if I can go to a really old version
cchoi22915 looks like you’re using power shell. Can you try from cmd.exe instead?
jaredwolff Ran the same command in cmd.exe with admin rights and the same issue occurs
What version of python do you have installed?
jaredwolff 3.10.4
What type of system are you running on cchoi22915 ? (OS and Architecture)
jaredwolff I am running Windows 11 ×64
Hmmmmm. I have a feeling it may have something to do with the Python install. Hard to say. There’s nothing on the repo that states you can’t use the latest/3.10.

Have you tried downgrading and using something like Python 3.7?
That is one thing I have not tried downgrading yet. I am currently creating an Ubuntu VM to see if it is an OS related issue. I will try to downgrade python and also try Linux to see how this fairs.
cchoi22915 sounds good. Sorry this is a pain.
jaredwolff no worries, thank you for helping. I will update on how it goes
jaredwolff Whoops, forgot to update this thread, but the issue continued to occur when I tried this in Linux. I was, however, able to follow the steps in LINK TO FORUM PAGE and successfully update the modem firmware.
That’s awesome! Thanks for letting me know cchoi22915
I ran into the same. On mac, the process to resolve was a bit different.
Here is the steps I used to resolve:
cp /Applications/Nordic\ Semiconductor/lib/libnrfdfu.dylib <PATH TO YOUR PYTHON SITE-PACKAGES>/pynrfjprog/lib_x64/
