ok, show adoption log comes up in a higher version
both leds solid means "system booting"
unfortunatelly your ap stucks
software fallback feature is enabled by default, maybe it recovers after longer uptime with the other image
if it still does not come up, the ap stucks in the beginning of the boot process and is not recoverabe by us cause officially there is no console port
if it comes up, maybe it will have the wrong (older) firmware from the other image bank.
therefore i would recommend to disable automatic firmware update on the controller if the ap adopts.
when buying aps on ebay, you do not know the fw version running, so disabling autoupgrade will definitely a good idea
if all fails, the only way is to open a rma case.
the ap650 got limited lifetime waranty, so no contract should be needed.
without contract the only thing is, that the repairing process time is undefinded.
could be some weeks, but it works.
