Title: Upgrading / replacing / reflashing firmware in ZyXEL VMG1312-B10A modem
Post by: Weaver on June 19, 2022, 05:17:41 AM
When I load new firmware using the ZyXEL web UI of my ZyXEL VMG1312-B10A modem, quite often the upgrade process simply fails. There’s a long delay with a rotating symbol to enjoy, I give it a minute or two and then try to guess what to do next. I can try hitting refresh in the browser, and then I often get back to the modem login page, I log back in and then go back to the firmware upgrade page I was at before, hoping to see the version name string or the bin filename. At that point the modem either shows me the old version name or shows the ‘rebooting - wait’ modal alert box. So basically I have no idea what’s going on and no clue as to whether the flash replacement will simply fail and leave me with the old firmware.

Do you see these same problems? What do you do? Is there a rock-solid, reliable procedure that I should be using to do firmware upgrades that succeed first time?

Is new firmware available?
My b10a will not save username and password in the pppoe field, only lets me set bridge mode.
Suggests that there is a bad batch of ROM chips out there.

I flashed one of mine today with the latest custom Johnson firmware. A very minor UI tweak for me compared with the latest published at the usual johnson website: https://github.com/johnson442/custom-zyxel-firmware/releases but my new release isn’t saved up there yet.

Not to my knowledge.

Is it a pure, vanilla, ZyXEL VMG1312-B10A or is it ISP branded?

Pure vanilla

Hmm . . . Your VMG1312-B10A is behaving in a very strange way.

It's been like that since it was retrieved from a customer's site.
It's got the official charger, so the only thing I can see is some kind of corruption of the flash memory.

@Burakkucat - is it essential to power-cycle the modem, or is there a way of remotely rebooting it? (Since I cannot easily get to the modem without wobbling from my bed to the office across the way.)

My reply, above, detailed a method that has always worked for me. (Could you enlist the help of one of the cats?)

Have you tried a hard reset as per this thread - https://forum.kitz.co.uk/index.php?topic=20731
