HAP AC bootloop after upgrade

I upgraded my HAP AC to ver 6.39.2 via WebFig.
The router keeps beeping in few seconds after powering up. I suspect it is a bootloop.
I had tried the pressing RESET button for 5 more seconds but it still back to bootloop

Anyone has experienced this? I am looking for help.

me too

the identical situation has arisen and at me, it does not get to use netinstall, does not help also reset all, if a variant with com port?

I have a hAP ac that is in a boot loop after a failed update, and it won’t connect to netinstall. The reset button starts an extended sequence of blinking lights–but once that has finished, rather than connect to netinstall, it just reboots.

As far as I know, it didn’t have protected-boot enabled. I guess I could systematically try releasing the reset button at various intervals in the hope of stumbling upon the right one, but for all I know the ethernet port could be damaged and no attempt will ever work. Any suggestions/insights?

Hap ac lite boot loop, I try reset, not responding.
