Converting GL.iNet MT3000 (Beryl AX) from CN to Global

Hardware Questions and Recommendations

I got the CN version from someone selling (without me knowing), unfortunately I had already opened and used it, etc. before I realized. I was able to convert it to the Global version by doing this (in order):

  1. SSH into the router and run the following:
echo "US" | dd of=/dev/mmcblk0p2 conv=notrunc bs=1 seek=136
sync
  1. Download the Common Upgrade (don't need UBOOT version) and drag and upgrade it within the admin console: https://dl.gl-inet.com/router/mt3000/

The above worked for me. I think setting the country to US first allows the firmware to be upgraded using the global version. In any case, if it's still showing CN (it didn't for me) after Step 2, simply run Step 1 again. A reboot may also help.
