Hello! After a complete reset, the device (L-71) stopped booting. I attach part of the log.

If you have a firmware image for it, you’ll need to copy it to a USB drive and boot the unit with the drive installed.
This will completely reformat the unit which should hopefully resolve the issue.
I believe what you have is a 1400 series.
Firmware can be downloaded from https://usercenter.checkpoint.com if you have a valid support agreement.

The firmware used is the latest R77.20.87 (990173005). I tried to update via USB, but unfortunately there is no result. Downloading the firmware via tftp also does not give a positive result. Maybe there are some other ideas?

USB Update:

- you connected the USB drive and the USB LED came up

- you rebooted the unit

- what did the console show at startup when trying to read from USB ?

I would record the console output during startup and contact TAC ! Maybe this is an RMA case...
