Good Morning,  
I am attempting to update my notecard firmware via notehub dfu from version 2.2.1.2013856 to 4.1.1.4015681.

The firmware downloads but I get an Error (modem: readbinary: busy)

I did retry and got the same error again.

Has anyone seen this issue that could tell me what I am doing wrong?

Matt

I tried with an earlier version of firmware and got the same error.  
Here is the last event in notehub

@Pechan is your notecard in continuous mode? If so try to temporarily turn that off. In theory not required, but I found it to resolve upgrade issues, in particular when in borderline cellular coverage.
