Hi,
I have a ZyXEL XGS1250-12 switch with latest OpenWrt snapshot version installed. Since then, no LAN port works (blinks) anymore.
I have a serial cable and I am able to connect there. But I dont know how to get latest stable version on the device to trigger a new flash.
Info for this device herehttps://openwrt.org/toh/zyxel/xgs1250-12#installation
latest stable files therehttps://downloads.openwrt.org/releases/23.05.5/targets/realtek/rtl930x/
Maybe you should consider returning to OEM firmware first, in order to have a proper default state. Than you install back OpenWrt.
What is displayed when you connect to the device with serial?
Yeah, I went through all of this already. But how can I restore OEM firmware first, if I cannot access the lan ports?
Via serial it looks like normal openwrt ssh. It even says, it listens on 192.168.1.1, it even shows if I connect via lan but it does not work.
With the serial link, if the interface offers some sort of file transfer. Can you log the console?
Is there a reset button? If so it can activate the failsafe mode, or even reset the settings
Have you tried this?https://openwrt.org/toh/zyxel/xgs1250-12#booting_openwrt_from_ram
@phqzgunsfjror Recovery is documented in the git commit:
committed 03:21PM - 17 Feb 22 UTC
The ZyXEL XGS1250-12 Switch is a 11 + 1 port multi-GBit switch with
8 x 1000Base… T, 3 x 1000/2500/5000/10000BaseT Ethernet ports and
1 SFP+ module slot.
Hardware:
- RTL9302B SoC
- Macronix MX25L12833F (16MB flash)
- Nanja NT5CC64M16GP-1 (128MB DDR3 SDRAM)
- RTL8231 GPIO extender to control the port LEDs
- RTL8218D 8x Gigabit PHY
- Aquantia AQR113c 1/2.5/5/10 Gigabit PHYs
- SFP+ 10GBit slot
Power is supplied via a 12V 2A standard barrel connector. At the
right side behind the grid is UART serial connector. A Serial
header can be connected to from the outside of the switch trough
the airvents with a standard 2.54mm header.
Pins are from top to bottom Vcc(3.3V), TX, RX and GND. Serial
connection is via 115200 baud, 8N1.
A reset button is accessble through a hole in the front panel
At the time of this commit, all ethernet ports work under OpenWRT,
including the various NBaseT modes, however the 10GBit SFP+ slot is not
supported.
Installation
--------------
* Connect serial as per the layout above. Connection parameters: 115200 8N1.
* Navigate to 'Management' in the OEM web interface and click on 'Firmware upgrade'
to the left.
* Upload the OpenWrt initramfs image, and wait till the switch reboots.
* Connect to the device through serial and change the U-boot boot command.
> fw_setenv bootcmd 'rtk network on; boota'
* Reboot, scp the sysupgrade image to /tmp, verify the checksum and flash it:
> sysupgrade /tmp/openwrt-realtek-rtl930x-zyxel_xgs1250-12-squashfs-sysupgrade.bin
* Upon reboot, you have a functional OpenWrt installation. Leave the bootcmd
value as is - without 'rtk network on' the switch will fail to initialise
the network.
Web recovery
------------
The XGS1250-12 has a handy web recovery that will load when U-boot does
not find a bootable kernel. In case you would like to trigger the web
recovery manually, partially overwrite the firmware partition with some
zeroes:
# dd if=/dev/zero of=/dev/mtd5 bs=1M count=2
If you have serial connected you'll see U-boot will start the web recovery
and print it's listening on 192.168.1.1, but by default it seems to be on
the OEM default IP for the switch - 192.168.1.3. The web recovery only
listens on HTTP (80) and *not* on 443 (HTTPS) unlike the web UI.
Return to stock
---------------
You can flash the ZyXEL firmware images to return to stock:
# sysupgrade -F -n XGS1250-12_Firmware_V1.00(ABWE.1)C0.bix

Thank you!!!
There it is mentioned to trigger the recovery with: dd if=/dev/zero of=/dev/mtd5 bs=1M count=2
