AC58U rebooting after flashing (bricked)

Hi followed method 2 below and now have a rebooting router.

First upload this one below and then flashed it... It said finished ok and said reboot manually.

Look at the router and saw it was just repeatedly power cycling every 30 secs or so. Tried a reset, still the same state.

Bricked? or A way out?

try rescue, see example
