GLAR750s ext Help!

I got this router a couple months ago, and just haven’t been able to get it working, I got it out of the box and tried the default IP to access the web GUI but it just wasn’t working, I then assumed it might need a firmware upgrade so I followed the steps to upgrade the firmware via uboot, I can’t seem to get passed this point, when I upload the .img file and select update it gets stuck on “update in progress” and nothing seems to happen after that, I even left it overnight to update, when I check the router it has all 3 lights solid green but still no way for me to gain access to the web interface, any thoughts?

Three green lights are on to indicate that the router is working properly.
Please connect to the router’s wifi, usually the name is GL-ar750s -XXX or GL-AR750S-XXX-5G.
