4 1/2 Ways to Unbrick Your (Gl.inet) Router!

This tutorial might help.

Enable TFTP in:
- Control Panel > Programs > Programs and Features > Turn Windows Features on or off
It may be necessary to:
- Disconnect from the internet and temporarily disable your firewall or permit TFTP operation.
Rename your firmware to firmware.bin.
Run Command Prompt as administrator.
- Command Prompt Commands:
- cd C:\[path]\[to]\[your]\firmware.bin
Insert the ethernet cable into the LAN port.
While holding the reset button down, plug in the power cable.
- Command Prompt Commands:
- tftp -i 192.168.1.1 put firmware.bin
Wait for the router LEDs to stop blinking.
WebUI should now be available at 192.168.1.1 or maybe 192.168.8.1. (This isn’t an exact science!)

(Useful for when Pineapple installation hangs)

Attach GND, RX, and TX lines to the header.
- Note: Slate routers may require soldering the header on. RX goes to TX and vice-versa.
PuTTY Parameters:
- COM port is unique to your system (port info is available in Device Manager).
- Baud rate: 115200.
Plug a USB stick into the router with the 19.07.7 firmware renamed to [yourModel]OpenWrt.bin.
- Commands in PuTTY:
- firstboot
- mount /dev/sda1 /mnt
- cp /mnt/[yourModel]OpenWrt.bin /tmp
- sysupgrade /tmp/[yourModel]OpenWrt.bin
Get back in via PuTTY:
- Open and edit network settings with:
- vi /etc/config/network
- Change any 172.x.x.x IPs to 192.168.8.1.
- Learn how to save and exit in vim and be amazed.
WebUI should now be available at 192.168.8.1!

In each instance, it may be necessary to set a static IP of 192.168.1.2.
If there’s a hang-up, try re-leasing your PC’s IP dynamically using DHCP.
If you have a gateway router already at 192.168.1.1, you’ll need to disconnect from it before connecting to any GL.iNet routers in recovery mode.
