Is there some test-mode that we can boot into for the W4500NEX? I tried using what i found on the forum, even on my older 4201NEX, and I was unsuccessful. If I can boot in a test-mode and can make a backup image, it would probably be ideal

I have a working W4500NEX SDcard. How can we go about test booting the W4500NEX unit to make a good a backup copy that can be applied to a higher quality SD card?

I have two W4500NEX headunits. the SD card failed on one of them. How do I backup the other one on the unit that is still working? I easily removed the SD card, but I cannot read it in Windows to backup up or make an image. I merely want to make a block level copy so I can use a reputable SD Card brand to mitigate this issue.
