How to recover the LG01 if firmware crash 

LG01 provide user a full control on its Linux system, it is possible that the device will brick and 

can’t boot after improper modification in some booting files.   

 

In this case, user can recover the whole Linux system by uploading a new firmware via Web 

Failsafe mode.   

 

Procedure is as below: 

 

Use a RJ45 cable to connect the PC to LG01’s port directly. 

 

Set the PC to ip 192.168.255.x, netmask 255.255.255.0 

 

Pressing 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 device detect a network connection and 

enter into the web-failsafe mode. Your PC should be able to ping 192.168.255.1 after device 

enter this mode. 

 

Open 192.168.255.1 in web broswer 

 

Select a squashfs-sysupgrade type firmware and update firmware.
