VMG5313-B10B - Upgrade to Lastest Firmware

Exelcius

Hello everyone!
Some issues occur when I try to upgrade the firmware of my modem (model VMG5313-B10B).
Currently, the firmware V5.11(ABBV.0)b13_20160525 is installed in my system and I'd like to upgrade it to 
the lastest firmware published on your site (5.11(AAYY.3)C0.bin or 5.13(AAYY.3)C0.bin).

When I try to upgrade with one of these versions (5.11(AAYY.3)C0.bin or 5.13(AAYY.3)C0.bin) an error occurs, saying that these are illegal images.
I try to upload from Chrome and Firefox but nothing has changed.

Someone can help me?
I search into the log file but there are no posts/information related to the upgrades attemps.

Some other information that can be usefull.
I'm writing from Italy and I have Wind/Infostrada as ISP.
I have a VDSL2 connection and my ISP gives me the modem.
When I asked to my ISP how to upgrade the modem, they told me to ask you.

Thanks a lot.

@Exelcius,

The firmware version is different.....
v5.11(AAYY.3)C0 is standard firmware of VMG5313-B10B,
and your firmware version is V5.11(ABBV.0),
maybe your version is customized for ISP,
you can check it first.

Thanks for your reply Rory.
I also think that my modem is customized for my ISP and I see that the version are different, but when I asked my ISP information on how to upgrade my modem, they answered me to contact directly the manufacturer to ask the right procedure to upgrade (so, I suppose that I can also upgrade to the lastest firmware). Maybe my modem is not upgradable due to the ISP customization but, maybe, exists a firmware version compatible with my modem.

@Exelcius,

As I know,
the upgrade feature of customized firmware almost be controlled by ISP,
they use remote management technology for management purpose,
such as software/firmware image management, status/performance managements and diagnostics.
Therefore I suggest to check with your ISP again.

Hi Exelcius,
You might be able to find how to upgrade the firmware from below user guide I found.
ftp://ftp.zyxel.com/VMG5313-B10B/user_guide/VMG5313-B10B_V5.11.pdf

However, I can't find the firmware ID you mentioned.
Maybe you could ask your service provide (Wind Italy) to provide the latest firmware version to you.
