I reflashed the clean OpenWRT firmware from <span style=“color: #222222; font-family: source_sans_proregular, ‘Helvetica Neue’, Arial, Helvetica, Geneva, sans-serif; font-size: 14px; line-height: 22px; background-color: #f9f9f9;”>GL.iNet download center;
I made a mistake in the configuration. So I tried to press and hold the reset button to get back to factory condition. No luck.
I then tried to put the device in u-boot, as described Overview - GL.iNet Docs I held the reset button and then added the usb power. The light flashed 5 times, then I saw the different light and released the reset button. But no u-boot interface is available at 192.168.1.1 (after switching my computer to 192.168.1.2, and connecting the computer to the LAN port of the AR-150).
Is entering u-boot different for the AR-150 after flashing the clean openwrt? Does that over-write the u-boot?
Somehow I got it back, so yes, definitely not bricked.
Wondering if by flashing the clean openwrt, we have changed the LED functionality. The 3-light version looks very different than what you posted in the video of the 6414. Perhaps another video can be done?
