Is it possible to extract the compiled binary file from Teensy 3.5 board?

[Veronika Parfentyeva]

I have a Teensy 3.5 board which was used before by other developer. However, the previous source code is lost and I want to, at least, get the old compiled binary file (.hex) from the board before uploading a new one.
Is that possible by, for example, using Teensy loader of Teensyduino?

Hi,

no, that is not possible.
I'd just use a new board and keep the old one.
