Nvidia nx operating system flash error

I’m having a problem with flashing with micro usb on the PC, I’m constantly encountering ihat in the terminal, I’m leaving the attachment of the error.

I noticed an ASCII byte error mentioned. This is probably wrong, but what is your output from:
echo $LANG
(use the same user you ran the command as; if this used sudo, then also use sudo)

If the output is not this:

$ echo $LANG
en_US.UTF-8

…then momentarily try this to run your command (I am using “sampleCommand”, but use the actual command which created the error:
LANG=en_US.UTF-8 sampleCommand

Assuming this was not your original “$LANG”, you could set the alternate LANG for your entire session via:
export LANG=en_US.UTF-8
(and then running your command)

I’m just hoping it is something simple to do with character set. Easy to test.
