    I am currently trying to assist my kids school set up 2 C2 3D printers. They have been sitting in the boxes for about 2 years or so now because nobody there attempted to set them up. One unit boots fine. The 2nd unit does not boot. I swapped the SD Micro cards and the one functional units SD Micro card can boot both units. I've attempted 3 reimages per the online instructions and have exhausted all my patience. Is there any config file that needs tweaking or is this an older image file that I need? Thank you in advance for any assistance.

    The C2 came in two flavors -- early ones used GPIO pins to drive the LCD.
    Later ones used an HDMI cable to drive the LCD (both used GPIO for the touchscreen)

    Both images are here on my google drive:


    Try them both... one should work if the machine is working.
    C2-HDMI-RoboOS-2_0.zip ---> HDMI image
    Robo_C2_GPIO_v2.zip ---> GPIO image
