@Mazin_D Let me rephrase. There are some options here.
1. You want to reinstall the box with R77.10. To get SW, you need a valid contract subscription in place. If you have it, you can download software from Check Point User Center. You will not have any support from the vendor for this version.
2. There is another _supported_ version, R77.30. However, it will go out of support in a couple of weeks. Same situation on the legal side, you need a valid contract to download.
Any other currently supported version will not work on IP290.
Honestly, I do not see any good option for you here other than buy new appliances and replace the outdated systems for good.
