Firmware FVS318N_v4.3.5-3.img invalid or corrupted

Trying to update my router to this firmware (FVS318N_v4.3.5-3.img) and both the web gui and the telnet interface keep complaining that the file is invalid or corrupted. Does anyone know how to solve this problem?

Thanks!

    Hi lumandryk,

     

    Welcome to the community! :) 

     

    As far as I know, there are no issues about upgrading the firmware of the FVS318N to v4.3.5-3.  Kindly answer the questions below:

     

    a. Is the PC/laptop you are using directly connected to the LAN port of the FVS318N? 

    b. What browser are you using to access the web-GUI of the FVS318N? 

    c. Have you tried using other browsers like Firefox or Safari to upgrade the firmware of the FVS318N via its web-GUI?

    d. Have you tried using other PC/laptop to upgrade the firmware of the FVS318N either via its web-GUI or via telnet? 

    e. Have you tried downloading the firmware v4.3.5-3 again then tried to proceed with the firmware upgrade either via web-GUI or telnet? 

    f. Have you tried to reboot the FVS318N then try again to upgrade the firmware to v4.3.5-3?

    g. What is the current firmware version of your FVS318N? 

     

     

    Regards,

      lumandryk,

       

      Thanks for the feedback.  I suggest you to try to clear the cache of the browser(s) you are using as well as try using other browsers like Firefox in upgrading the firmware via the web-GUI of the FVS318N. 

       

       

      Regards,

        Just tried upgrading the firmware via web-gui in firefox (freshly installed) and as expected it didn't work, said that the firmware was invalid or corrupted. FWIW I also tried installing previous versions, from the very same files that worked in the past, all failed in the same way. I also tried the telnet route, unsuccessfully as well.

        Any other suggestions? Is there a way to force installation and bypass all validation?

        Thanks!
