For the , "firmware downgrade" is usually pursued as a cost-saving feature to bypass Dynamic Security measures that block third-party ink . Key Feature: Restoring Third-Party Ink Compatibility
In Jetadmin, go to the "Firmware" section, then "Repository", and select "Upgrade Firmware". Choose your printer, and when prompted, select the older firmware version you want to install. The software will then push the older firmware to your printer.
For many owners of the HP OfficeJet Pro 8620 downgrading firmware is a strategic move to restore functionality for third-party ink cartridges that have been blocked by HP's Dynamic Security
The most severe version of this problem was observed with version FDP1CN2022AR . A request for help sent to HP Support in May 2025 illustrates the nightmare: the user reported that after the update, the printer began rejecting genuine HP 950 and 951 cartridges that worked perfectly before the update. The printer would display errors when all four cartridges were installed, but would only work if three were inserted. This is not just about blocking cheap ink; it was breaking the core functionality of the device.
HP OfficeJet Pro 8620 Firmware Downgrade Better? A Complete Guide to Bypassing Third-Party Ink Blocks Downgrading your HP OfficeJet Pro 8620
Rolling back to a stable legacy firmware version like bypasses this gatekeeper completely. It allows you to reclaim ownership of your physical hardware and drastically reduce operational printing costs. Why a Firmware Downgrade is Better 1. Bypasses Dynamic Security Restrictions
Furthermore, modern operating systems (Windows 11, macOS Sonoma) and mobile devices rely on specific driver protocols. As HP updates its "Smart" apps and driver architecture, compatibility with firmware versions that are five or more years old may degrade. Users who downgrade may find themselves unable to scan to email via modern OAuth 2.0 security protocols or unable to use mobile printing features that were introduced or patched in later updates.
If you successfully downgrade your firmware—or if your printer is currently working fine with third-party ink—you must take steps to keep it that way.
: Reverting to an older version sometimes restores the printer's ability to display ink levels for compatible cartridges. Important "Better" Alternatives
When HP locks out a third-party cartridge, consumers are forced to throw away perfectly good, full ink tanks. Downgrading allows you to use every last drop of ink in your current tanks, reducing electronic and chemical waste. 4. Preservation of Local Network Functions
