Installing and Using OpenWrt

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...

Hi NilsRo,

Thanks for the hint. I tried without success. I "should" have the same Switch "GS1900-24E (v2)" Revision B1 ?
Can you elaborate in more detail the procedure ?

  1. Should I a) press the reset button before plugging in the switch or b) plug in the switch and wait X seconds before pressing the reset button ?
  2. How long should I press the reset button and would any LED show a reaction after some time of pressing the reset button ?

Thanks a lot in advance ! and
Cheers, Blinton.

Its simply the factory reset. I found i described like this: "Firstly, I recommend isolating your GS1900-24E. To do this, press the restore button on the front panel for 10 seconds. This action will reload the factory default settings on the switch. After this step, please connect your PC directly to the GS1900-24E. You can log in to the GS1900-24E using the default IP address, which is 192.168.1.1."

That worked for me. Perhaps flashing the default firmware does not reset the settings...done it with power connected if I remember correctly but do not know that for sure. Too long in the past...

Is your switch broken also after flashing OEM firmware?
