This naming trick fools the printer’s updated security checks.
On your printer’s touchscreen:
If it’s FDP32B, FDP32C, or any version above FDP32A, you are a candidate for downgrade.
Before we dive into the downgrade process, let’s understand the battlefield.
HP employs a security system called Dynamic Security. It’s designed to ensure only cartridges with new HP chips work. Every few months, HP releases a new firmware update that “improves security” – a euphemism for breaking compatibility with non-HP cartridges.
If you’ve recently updated your OfficeJet Pro 8620 (whether intentionally or via an automatic update), you’ve likely encountered: hp officejet pro 8620 firmware downgrade new
The only way to reverse this is a firmware downgrade. HP doesn’t advertise this, but the pre-Dynamic Security firmware versions still exist – and they work perfectly.
Most practical advice: If you need cheap ink, sell your updated 8620 and buy an older printer (e.g., Brother) that never uses dynamic security.
To downgrade the firmware on an HP OfficeJet Pro 8620, you generally need to manually run an older .exe or .dmg firmware installer from a computer connected to the printer via USB or network. Important Warning
Downgrading firmware is not officially supported by HP. It can lead to the following risks:
Bricking the device: The printer may become permanently unusable if the process is interrupted.
Security risks: Older firmware often lacks critical security patches found in newer versions. HP USB Recovery Tool (Optional but recommended)
Voided warranty: Unauthorized firmware changes can void your manufacturer warranty. Typical Downgrade Steps
Locate the Firmware File: You must find a specific older version (e.g., version 1400 series or earlier) from a trusted third-party archive or community forum, as the Official HP Support Site typically only provides the most recent version.
Disable "Printer Update": Before attempting a downgrade, ensure the printer won't immediately re-update. On the printer control panel, go to Setup > Printer Maintenance > Update the Printer > Printer Update Options and select Do Not Check.
Run the Installer: Connect your printer to your PC via USB. Run the downloaded firmware utility on your computer. If the utility finds the printer, it may allow you to "Update" even if the version is older.
Confirm on Printer: Watch the printer's display for a progress bar. Do not turn off the printer until it restarts completely. Alternative: Factory Reset
If you are trying to resolve a software glitch without the risks of a manual downgrade, a Factory Reset may help: Do not use the “HP Easy Firmware Update”
On the printer display, go to Setup > Tools > Restore Factory Defaults and confirm by selecting Yes. Managing Future Updates
If your goal is to prevent the printer from blocking third-party ink cartridges (often the reason for downgrading), you can disable automatic updates using the HP Smart App by navigating to Printer Update > Auto Update > Off.
