Downgrading the firmware for the HP OfficeJet Pro 8620 is a common quest for users wanting to restore compatibility with third-party or refilled ink cartridges. The Conflict: "Dynamic Security"

• Restores third-party/refilled ink cartridge compatibility – Newer HP firmware actively blocks non-HP cartridges via Dynamic Security. Downgrading to a pre-2019 version (e.g., RP1-1719AR or earlier) often re-enables them.
• Bypasses region-locked cartridge errors – Some users report success fixing “cartridge incompatible” messages after downgrading.
• Recovers lost features – Occasionally, newer firmware removes or breaks certain scan-to-network or fax functions; downgrading can restore stability.
