Hello, may I ask which interface you used to update the firmware in the link
https://docs.gl-inet.com/router/en/3/tutorials/debrick/,
192.168.1.1 or 192.168.1.1/uboot.html?
In addition, there are two firmware options in the interface 192.168.1.1, and the firmware downloaded from the download site https://dl.gl-inet.com/?model=ar750 ends with bin, so you need to use the firmware in the NOR flash firmware.
192.168.1.1:
192.168.1.1/uboot.html:
