I have appliance 1490 on locally management. After suffering an automatic update of the firmware that caused me problems, I decided to change to manual update.
The appliance had R77.20.80 build 990172392 and was updated to R77.20.81 Build 990172541. When they released R77.20.85 the appliance never detected it, I had to download it and do the manual update. Even though R77.20.85 corrected me some things that were giving me a headache, it brought me a new problem, after a few hours and with the normal network traffic of the client, the firewall no longer allowed traffic to the Internet and no I could manage it, it did not respond to the ping either. I have a ticket raised for this problem, recently released a new build but the problem persists. The point to the original question is that the technical support of checkpoint told me that it is possible that the area responsible for firmware updates has "deactivated" the detection of this firmware for the problems it has presented.
