Updated Marlin Firmware not working

New to the 3d Printing world, and now having problem with my firmware update.  Had several problems with the firmware that came installed on printer so I decided to upgrade.  Now the printer does not respond to any commands.  Any help appreciated.

    Can you connect with protorface? Send a M502, M500, M503 command and send us what the output is.

    I'm assuming you selected the correct board in the Arduino IDE before the flash correct?

    Printer is now online.

    Ok, so there is something wrong with the temperature measurements. Are the nozzle or bed hot when you turn the printer on? Or perhaps is a thermistor cable loose for the bed or the nozzle?

    It does appear that the therminster is the problem.  Thanks for the help.
