Step 4: Run the Firmware Downgrade

Right-click the firmware executable file (e.g., OJ8620_1738A.exe) and select "Run as Administrator."
The HP Firmware Update Utility will launch. It should automatically detect your printer via USB.
Confirm the model displayed matches "HP OfficeJet Pro 8620."
Click "Update" or "Install." A progress bar will appear.
- First stage: Uploading firmware to printer memory.
- Second stage: Printer screen will go blank, then show "Updating Firmware – Do Not Turn Off."
Wait. The entire process takes 5–10 minutes. The printer may restart once or twice.
Upon completion, the utility will show "Update Successful." The printer will reboot to a ready state.

If the update fails: The utility will show an error like "Firmware older than current version cannot be installed." This means HP has locked the bootloader on your printer – you cannot downgrade. Some advanced users have attempted using a "downgrade package" via the printer's hidden Service Menu, but that is extremely risky and not recommended.

9. Legal and support considerations

Modifying firmware may breach terms of service or support agreements.
If you require official support, disclose any firmware changes when contacting HP support.

Verdict

Recommended for: Tech-savvy users who rely on cheap third-party cartridges and are willing to tinker, accept bricking risk (low but possible), and permanently block HP updates.
Not recommended for: Casual users, businesses under warranty, or anyone needing reliable out-of-the-box functionality.

Pro tip: Before attempting, search for “HP OfficeJet Pro 8620 downgrade firmware 1719AR” in printer forums. Back up settings, and after success, disable Printer Updates in the Embedded Web Server (EWS) and block *.hp.com on your network if possible.

Why HP Pushes Firmware Updates (And Why You Want to Go Back)

HP’s "Dynamic Security" feature is designed to ensure that only new, genuine HP cartridges work in their printers. While HP claims this protects print quality and security, critics argue it is a tactic to lock customers into expensive first-party ink.

When HP releases a new firmware version (e.g., from 1738A to 1743A or 1759A), it often:

Updates the dynamic security database.
Blocks previously working refilled or remanufactured cartridges.
Disables the ability to use older, still-full third-party cartridges.

The result: Your printer may show errors even though the cartridges have ink. The only solution for many is to downgrade to an older firmware version that existed before the latest security patch.

Step 1: Disable Internet & Auto-Update

On your printer’s touchscreen, go to Setup > Network Setup > Advanced Setup.
Turn Off the option for "Allow Automatic Updates" or "Auto Update."
Unplug the Ethernet cable or forget the Wi-Fi network to ensure the printer has no internet access during downgrade.
