I've recently flashed an AR300M with the latest 4.3.18 (from 4.3.17) - Common Upgrade, the router rebooted and I accessed the WebUI, then I put away the router. Upon the next boot, today, I saw all 3 LED flicked once shortly then dead afterwards. I checked 2 power bricks and 2 micro-USB cables with my USB tester, and as soon as I plug in the router - the USB tester turns off (a short, I guess). I think, the router is dead...
EDIT: could a power brick kill it?
Has anyone else experienced it after flashing 4.3.18 on AR300M? Is there ANYTHING I can do to recover it?
