  1. I have downloaded EC152 modem dongle firmware trying to follow your instruction but getting error message
    The data card can’t be found. Error code:3
    One of the following reasons may cause the error:
    a. The Data card is not properly connected to pc
    b. other program is using the data card.
    c. you do not have the authority of the administrator

    I have also tried EC150 firmware for this one but showing the same error message. I am not using this photon from last one year.
