10.3 Debrick via Uboot

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 our video, How to Recover GL.iNet Mini Router by U-Boot

FailSafe.

1. First you have to download firmware to your computer. You can download

the firmware here. For GL-AR300M, GL-AR300M-Ext, GL-AR750S-Ext,

please download the .img firmware file. For GL-B1300, GL-S1300, please

download the .img firmware. Everyone else, download the .bin firmware file.

2. Connect your computer to the Ethernet port (either LAN or WAN) of the

router. You MUST leave the other port unconnected.

3. 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.)
