Hi, 

I cannot reproduce the issue. Maybe the download package is not downloaded completely or for other reasons, but good to know you fixed the issue by installing via the Internet.

Hi,

I did it all over again to be safe, I inserted a USB stick (E:), downloaded “nrfutil.exe” ( link ) I went to the download folder and typed the command “nrfutil prepare-offline E:/nrfutil-offline”, this is the result

Could you try another USB stick?

Your version is a bit old. You can upgrade the nrfutil by this command: nrfutil self-upgrade

Then upgrade the installed commands: nrfutil upgrade

I did another test, if I bring the 'nrfutil-offline' subfolder to the USB stick and try to install on the machine without connection (Windows 10) with 'nrfutil install device --from-offline E:/nrfutil-offline', I get:

Error: Failed to bootstrap core functionality before executing command.

When do you download the package? Could you try this zip file nrfutil-offline.7z? Unzip it to your USB stick.

HI
I tried with at least 4 USB sticks, always the same.
I re-downloaded “nrfutil.exe” (again), put it in the USB stick where I unzipped your compressed file and attempted to install it on a physical Win10 machine, even with internet access this is the result:

Then again on this machine I recreated my 'offline' package and tried to install it from a USB stick, this is what I got:

I'll try to update the version on my PC and redo the package, but at this point I have little hope, I'll let you know then, but I'm afraid we're missing something...

Hi, 

Your nrfutil version is quite out of date. Please try running nrfutil self-upgrade and then running it again (for various reasons it is required to do it twice at this particular transtion point but it should be needed to do it twice in fufure.)

If it doesn't recognised self-upgrade as a subcommand then please re-download nrfutil from the Nordic website https://www.nordicsemi.com/Products/Development-tools/nRF-Util

Once you've done either of those then please try the prepare-offline command again.

Hello

I finally understood the mystery, is the twice upgrade ... now have the lastest version and all works, but I'm afraid I can't solve my problem, from what I understand so far I should do the 'nrfutil self-upgrade' command twice which requires internet connection on a machine that doesn't have it... I saw that it depends from the '.nrfuit' folder in the user directory, I have to do some tests then I'll let you know

Hi

I think I have solved my problem, in practice I copy the .nrfutil folder into the Windows user folder (taken from a PC where the tools I need are already installed and functioning) and from the tests I have done this avoids the need to upgrade and installations with active internet connection.

But is there an implementation, C or C++ or other languages, of nrfutil to include in your own executable?

Unfortunately, there are no such resources and currently no plans to provide that.
