I posted recently on here about trying to update firmware on a Sharp MX-5141n. I thought I could build a new SD card from the file on a USB stick. I have been told that this method will not work and that I have to get a Sharp SD card with the files already on it or find an SD card that has been cloned. I am not a Sharp tech - I work on HP machines mostly. Does anyone have an SD card or access to the files needed for cloning? Don't mind paying - just trying to get this machine fixed for a customer and move on... Thank you for any help.
