What is the latest SM-J400G firmware?
J400GDXS9CVE1, released August 2, 2022 with Android 10. It is a security update on bootloader binary 9. The archive holds 20 official builds across 10 regions (CSC). Each one is the full stock ROM (flash file) for Odin, not an OTA patch.
Is the Samsung SM-J400G still getting updates?

Can I downgrade the SM-J400G firmware?
Only to builds with the same bootloader binary (the Bit column) or higher. All decodable builds in the archive share binary 9:
