How to recover the LG308 if the firmware crashes
LG308 provides the user with full control on its Linux system, so it is possible that the device will
brick and can’t boot after an improper modification in some boot files. In this case, the user can
recover the whole Linux system by uploading a new firmware via Web Failsafe mode.
Procedure is as below:
●
Use an RJ45 cable to connect the PC to LG308’s LAN port directly.
●
Set the PC to a static IP of 192.168.255.x, Netmask 255.255.255.0
●
Press and hold the toggle button and power on the device.
●
All LEDs of the device will blink, release the toggle button after
four
blinks
●
All LEDs will then blink very fast once, this means that the device has detected a network
connection and will enter into the Web-Failsafe mode. Your PC should be able to ping
192.168.255.1 after device enters this mode.
●
Open 192.168.255.1 in web broswer
●
Select a
type firmware and update firmware.
Note: If you see all LEDs blink very fast in Step 5, this means the network connection is
established. If in this case, the PC is still not able to see the web page, you can debug as follows:
✔
Try different browser.
✔
Check if your PC is set to static IP address of 192.168.255.x
✔
Check if you have connected two RJ45 cables to device. If so, remove the unused one

I configured LG308 for WiFi access and lost its IP. What to do now?
The LG308 has a fall-back IP address on its LAN port. This IP is always enabled so you can use the
fall-back IP to access LG308 no matter what the WiFi IP is. The fall back IP is useful for connecting
and debug the unit.
(
Note:
fallback IP can be disabled in the LAN and DHCP page
)
Steps to connect via fall back IP:
1. Connect PC’s Ethernet port to LG01’s LAN port
2. Configure PC’s Ethernet port has
IP: 172.31.255.253 and
Netmask: 255.255.255.252
