Using Uboot to Debrick Your Router¶
You may have bricked your router if you were doing some DIY projects or flashed a wrong firmware. You may not be able to access your router but you can re-install the firmware by using Uboot failsafe.
Please follow the procedures below to access the Uboot Web UI and re-install the firmware.
You can also refer to video tutorial below.
First you have to download firmware to your computer. You can download the firmware here. Some models, such as GL-AR750S-EXT, it is available in two formats of firmware, please use the firmware with the .img extension.
Connect your computer to the Ethernet port (either LAN or WAN) of the router. You MUST leave the other port unconnected.
Press and hold the Reset button firmly first, and then power on your device. (If your device does not have a power button, plugging it in will power it on automatically.)
If you can not find the reset button, please refer to our page, How to Repair and Reset.
Release your finger when you see the LED has flashed:
The Power LED will light up. Then, other LEDs will start flashing.

Set your computer’s IP address to 192.168.1.2. Please check the step-by-step guide for different operating systems below:
Windows 7 / Windows 10

- Right click Local Area Connection -> Properties.
- Click Internet Protocol Version 4 (TCP/IPv4) -> Properties.
- Set the IP adress to 192.168.1.2 manually.
- Go to System Preferences -> Network.

- In Configure IPv4, choose Manually.
- Set the IPv4 Address to 192.168.1.2 manually.
Use Firefox or Chrome to visit http://192.168.1.1.
Click Choose File to find the firmware file. Then click Update firmware.
Wait for around 3 minutes. Don’t power off your device when updating. The router is ready when both power and Wi-Fi LED are on or you can find its SSID on your device.
