How can I update version R75.20 (983003552)

[yagel]

Hi,
I have an L50 with an old version R75.20 (983003552) firmware for 600/1100 Appliances And I want to update her

Both HW and SW are discontinued long ago.

If you have a valid support contract to download the files you would likely need to perform a multi-step upgrade to R77.20.8X

Please refer: sk120512 - Firmware upgrade paths for 600/700/900/1100/1400/1200R appliances

sk97766 - Small and Medium Business Appliances - Releases R77.20.X

As End of Support for these models was June 2022 and End of Engineering Support was June 2020, R77.20.80 is the last official firmware release for 6x0/11x0 appliances, see https://community.checkpoint.com/t5/SMB-Gateways-Spark/SMB-Appliances-R77-20-81-firmware/m-p/40760. But to upgrade would need valid support on 600/1100 units and maybe you have to cope with https://support.checkpoint.com/results/sk/sk111332

As the main thing is TP - it would not make much sense to use 600/1100 units without TP blades anyway.
