Downgrading iLO 4 firmware is a common task for users looking to restore specific features—like , which was removed in later versions—or to resolve stability issues. While the process is generally straightforward, security updates in later versions (specifically v2.80 and above) can block downgrades to versions below v2.54 to protect against critical vulnerabilities like CVE-2017-12542 .

The ILO 4 Firmware Downgrade Conundrum
- Your server is internet-facing. Older firmware has known vulnerabilities (including the infamous CVE-2021-44228 - Log4j). If your iLO is exposed to the public internet, you must stay on v2.90+ (or better yet, disconnect it from the WAN).
- Your compliance team demands CVEs. If you are in finance, healthcare, or defense, downgrading is a violation of security policy.
- You have a specific hardware revision. Some late-production Gen9 servers may refuse to boot with firmware < 2.80 due to CPU microcode dependencies.
