firmware update version 6.3.5s017

Good morning guys!
I have a Balance 305 with firmware version 6.3.5s017 build 3643, but I can’t update it, it keeps giving me an image error.
Can anyone give me a suggestion on how to solve this problem?

Hi.
Look at the Hardware Revision of your device…
Can it support up to date firmware version?
also… . first you need to upgrade your device to 7.1.2 software version.
Regards…

Thanks for the suggestion, but I’ve tried several versions and none of them work.

hello…
Look at status page… look at hardware revision… Is your box a hardware 1 ?
So… there no update version for it… You cannot update it to 7.x.x or 8.x.x
Got this from the support page:

  • Balance 305 HW1 6.3.4 ;;; sorry… end of road for your device.
    The 6.3.5s017 I am not sure… but 6.3.5s020 was made for EDNS compliance.

What a shame

Thank you for your help, Marcelo Barros.
