Here is an image file Yaesu_FTM-7250D.img for testing purposes

First, thanks for sending this as a binary patch -- it makes it a lot easier for me :)

However, the file needs to be named very specifically and since you have VARIANT="R" in the driver, this needs an "_R" in the filename before the extension. I've tweaked it locally, but just FYI for next time.
