AR750 upgrade from 2.272 > 3.0 CLEAN TO WEBGUI

I tried to upgrade firmware on AR750 from 2.272 to 3.0 CLEAN but after upgrade it goes to
Www. console only.

I also tried www.

Is the file corrupt or I would need to do something else.

The"clean" firmware version doesn’t have the gli interface built into it, only luci. If you want the gli ui you should install the non clean version.
