Zyxel GS1900-24E: go back to OEM firmware

Hi,

I like to go back to OEM. How can this be done? Tried fw_setsys bootpartition 1 which does not work. Found this in another post. Also flashed OEM via LuCi and not the switch does not seems to come back available…

Cheers
Nils

Ha, I saw in the sys led that something is booting and a reset via the button has to be applied. Not the Zyxel GS1900-24E is back online with OEM firmware. Perhaps this helps somebody...so very easy to revert back...
