Hi Tony, Thank you for the input, I had not seen the first document before, whereas I used a shorter version ( https://support.zyxel.eu/hc/en-us/articles/4403365084818 ) of the second link you sent to find all the modem firmware and module firmware upgrade files that I used. Having looked through the document,…

This kind of "put-it-on-the-store" policy would make sense if they've delegated primary repairs and support to certified vendors as some companies do, and if the vendor was also responsible for doing the setup. If the product in question was a bike with a loose pedal, that had to be fixed by a shop, it would makes sense…

That sounds strange indeed - and I can imagine that it's hard to get through to support about this matter as the support request will start with them asking for a product SN. Effectively a catch-22 paradox, unless you can reach them through some other channel (Facebook / Phone) to try to get some help. If you get through…

Hi Bob, I actually tried doing this, but when I entered the modem SN, I was told that the device had been purchased through a provider (guessing telephone / internet company) and that I should contact them for support. Unfortunately for me, I purchased the modem new (unused) but second-hand, through a website like…

I have now tried to do as you suggested, I downgraded the firmware to ABUV4 (which went perfect), and tried upgrading the module, but got the same error, again and again. I upgraded again to V7 and gave it another try just for good measure, but still no luck. Back to the old drawing board I guess.

You are correct. I found the option there!

Thanks for the suggestion, I will try to downgrade the firmware to update the module firmware. Maybe I should try leaving the sim card in, as it seems to work for you. There seem to be two options in the web interface, a Restart and a Reboot. But pressing the restart button gives a box that allows you "Reboot", whereas…

Unfortunately, this was not the case for me. After a failed upgrade, the modem does indeed seem to reboot, but the module firmware remains the same old version as before (checked by putting the sim-card in and rebooting the device). 

Hi Selberg, Thanks for answering, yes I am certain that I performed a factory reset. I do not think that the Web GUI even has a proper "reset" option, just "reboot", as pressing the "restart" button in the side menu brings up a confirmation window asking if you want to "reboot".. I followed the instructions in the user…
