After receiving my Nano and reading about BenF’s efforts here, of course I want to upgrade.
I followed all the steps in the manual (upgrading both the APP and LIB files) and note that after transferring, the verify was successful.
But when I cycle the power, I see I still have the old firmware. During the transfer I did get the error:
"Your device was plugged in DFU mode.
So it is impossible to make sure the file is correct for this device.
and clicked “Yes”.
I’m using Win2K, if that’s an issue.
