"Did this work on your 8620? Tell me the last 4 digits of your old firmware in the comments. If you see 'Update blocked by admin,' you need to perform a factory reset before starting Step 3."

I love my OfficeJet Pro 8620: fast color printing, decent scan quality, and a touchscreen that — mostly — behaves. But after a recent firmware update it started acting… different. Slow wake-from-sleep, flaky AirPrint, and a new setting buried in menus that I hadn’t asked for. I tried every standard fix (reset, reinstall drivers, factory restore) before doing something a little risky: I downgraded the printer’s firmware. Here’s the story, why I did it, how I did it, and the trade-offs so you can decide if it’s worth trying.

    Alternatives to downgrading

    Final thoughts Downgrading firmware isn’t for everyone — it’s a last-resort tool when a recent update harms your daily experience and other fixes fail. It restored my OfficeJet Pro 8620’s previous snappiness and fixed the AirPrint flakiness, but it also required patience and care. If you go down this path: document every step, keep backups of settings, and be prepared to restore to the latest firmware if you hit unexpected issues.

    Downgrading the HP OfficeJet Pro 8620 firmware is a common method to bypass "Dynamic Security" locks that prevent the use of third-party ink cartridges.

    A key "new" feature for the HP Officejet Pro 8620 firmware downgrade is the Automatic Update Lockout

    . This feature allows you to permanently disable the "Check for Updates" function after successfully rolling back to an older firmware version (like FDP1CN1416AR

    By locking out these updates, you prevent the printer from automatically re-applying "Dynamic Security" patches that block the use of non-HP or refilled ink cartridges. Key Benefits of the Downgrade Feature Cartridge Freedom

    Disable "Cartridge Protection": Go to Setup > Tools > Restore Factory Defaults to reset protection settings.

    Turn off Automatic Updates: Navigate to Settings > Printer Maintenance > Update Printer and set it to Manual.

    Stable Connection: Use a USB cable instead of Wi-Fi for the downgrade to prevent bricking. 🛠️ Downgrade Methods Method 1: Windows Downgrade Tool

    Source the File: Find an older .exe firmware file from reputable third-party archives or community backups (e.g., CompAndSave or YB Toner).

    "Not Applicable" Fix: If the tool says the update is "Not Applicable," right-click the .exe, extract it with 7-Zip, open EnterpriseDU.ini, and change VerifyDownloadID from 1 to 0.

    Run & Send: Open the modified tool, select your printer, and click Update. Method 2: USB Drive (Alternative) Format a USB drive to FAT32. Save the older .ful firmware file to the root of the drive. Insert the drive into the printer's front USB port. If the printer asks "Upgrade detected?", select Yes. Method 3: Factory Restore (Limited Success) Go to Setup > Tools > Restore Factory Defaults.

    This does not always roll back the firmware version but can clear "Protected Cartridge" blocks that prevent third-party ink from working. ⚠️ Important Risks

    Bricking: Interruption during the process can make the printer inoperable. Security: Older firmware lacks the latest security patches.

    💡 Pro Tip: After a successful downgrade, go back into settings and triple-check that "Check Automatically" is turned OFF so the printer doesn't re-update itself. If you're stuck, let me know: What firmware version do you currently have? Are you on Windows or Mac? Is the printer connected via USB or network?
