I see you are talking to cafebug to.
The latest stable firmware for version 3.x is 3.214 this was based on chaos calmer 15.05 a deprecated version of openwrt
4.x is the newest firmware and GL.iNet User Interface is based on openwrt 21.02 and LuCi 22.03
You will need to use uboot to upgrade past 3.214 to 4.10.0
Also will want to update uboot before
That’s a uboot bug, the fixed version can be downloaded here .
Upgrade uboot by the following steps:
- connect LAN and PC by ethernet, the PC’s ip should be 192.168.1.x
- push the reset button and power it on, about 10 seconds later release the button, until the wifi led stops flashing and the white led turns on.
- access http://192.168.1.1/uboot.html to flash uboot.
