GS1200-5 upgrade stuck to upgrade failed

Veijo

..and try again.
Tried, a few times.
First tried the latest 2.00(ABKM.3)C0, then "downgrade" to V2.00(ABKM.2)C0
Downloaded V2.00(ABKM.1)C0, but i have not tried it yet.

I have read all the questions about this problem, tried all the methods (except curl), but no working solution found.

No matter if i reset the switch. It is the same page "upgarede failed" again and again.

Linux OpenSuse Firefox & Chromium with or without addons, security settings on and off.

Hi @Veijo

When you were trying to upgrade the firmware for the switch, did you connect your PC directly to the switch, or was the connection made through a VPN?

Besides, please make sure it is the .bin file that should be downloaded on the product page here.

Best regards

Veijo

Directly, no VPN and the file from the product page.
I'll try upgrade from a windows computer and how it went.

Veijo

.. and it worked 🙂
I renamed the file as firmware.bin as did someone else here when upgrading some version of GS1200.
That maybe pointless, but thought maybe there is some magic in it.

And of course copied the file to the root C:\

Hi @Veijo

I'm glad to know that you solved it.

Please let us know if there is anything else we can help with.

There seems to be a problem with the upgrade procedure under Linux: I recently flashed 2 of them (from Linux + Firefox or Chromium, as well as from Android) which remained in "upgrade failed" mode. Fortunately, Zyxel sent me 2 back as I didn't have any Windows available. So I didn't dare upgrade any more.
Thanks Veijo for the info, I'll try to find a Windows to recover the switches.

xfs, unregistered windows 10 is enough. I have a spare laptop with win10 and used it to upgrade.
