After upgrade from 7.13 to 7.14beta3 my cAP AC bricked

I upgraded 7.13 to 7.14beta3 and my cAP AC and actually my cAP AC is brick. The diodes are active but after few minutes cAP restarted. I think that it is in looping boot or something like that :confused:
What could I do ?

Netinstall

Tried many times but didn`t appear in netinstall router/drives window :confused:

wifi distabled
eset disabled
network lan configured to 192.168.88.2
netinstall run as administrator
netbooting client address configured as 192.168.88.3
netboot server enabled

Try reset cAP AC with 15 seconds reset button pressed when POE ethernet on. Tried 20 seconds and more, without success :confused:

Try a dumb switch in between device and computer.
Try keeping reset pressed until it appears.

Personally I have a lot more success using a Linux laptop for netinstall.
