Firewall Checkpoint L50 won't start

[danieledebernar]

I reset the firewall to factory settings but it won't boot up properly and it doesn't show up in network resources or even its IP address. How can I solve this?

That makes sense.

This was bought 30-Sep-2013 as i can see ! Solution is available in sk123499:

As a workaround, run the following commands in Maintenance Mode:

• # date -s "010101012018"
• # hwclock -w --localtime
• # reboot

For a permanent fix (if the appliance is reset to a factory image lower than R77.20.15, the issue will occur again), do a fresh/clean install to R77.20.15 or higher

This is bad, as without valid support contract you are not entitled to download R77.20.80 firmware...

I asked sales support about the cost of the license

You've encountered the exact bug I was referring to.
@G_W_Albrecht has the correct workaround for this.
