The HP OfficeJet Pro 8620 is a popular all-in-one printer, but many users find that recent firmware updates have restricted its functionality, particularly regarding the use of third-party ink cartridges. Downgrading the firmware to an earlier version is often considered a "better" option for users seeking cost-effective printing and greater control over their hardware. The Case for Downgrading: Why It’s "Better"
For many users, the primary motivation for downgrading is to bypass HP's Dynamic Security feature. This feature is designed to ensure the printer only works with cartridges containing original HP chips. While HP frames this as a security and quality measure, it effectively blocks more affordable third-party or remanufactured alternatives.
Cost Savings: Downgrading allows for the use of compatible ink, which can be significantly cheaper than genuine HP cartridges.
Restored Functionality: Users often report that recent updates cause "Non-HP Chip Detected" or "Cartridge Problem" errors that prevent printing entirely. An older firmware version (such as FDP1CN1416AR) often resolves these lockout issues.
Freedom of Choice: It restores the user's ability to choose their preferred ink supplier without being locked into the HP ecosystem. Risks and Trade-offs
While downgrading offers clear financial benefits, it is not without risks. HP generally discourages the practice for several reasons: hp officejet pro 8620 firmware downgrade better

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
. While HP officially states that downgrading is not possible or recommended due to security risks, many users find it necessary to bypass "Non-HP Chip Detected" or "Cartridge Problem" errors. Why Downgrading is Often "Better" Bypass Cartridge Lockouts
: Recent firmware versions actively block non-HP cartridges. Reverting to an older version allows the printer to recognize and use affordable, third-party, or remanufactured ink again. Cost Savings
: Using generic ink can significantly reduce printing costs compared to expensive OEM HP 950/951 cartridges. Reliability for Legacy Supplies
: If you have a stock of older generic cartridges, they may only work with the firmware version they were originally designed for. Risks to Consider
The HP OfficeJet Pro 8620 is a workhorse, but HP’s "Dynamic Security" firmware updates often block perfectly good third-party ink cartridges. If your printer recently stopped recognizing your non-HP ink, downgrading the firmware is usually the only way to regain control.
Here is a comprehensive guide on why downgrading is better and how to do it safely. Why Downgrade Your HP 8620 Firmware? After downgrading, HP will immediately try to update again
HP frequently pushes updates that serve one primary purpose: ensuring you only buy original HP supplies. By reverting to an older version, you unlock several benefits.
Third-Party Ink Support: Use affordable remanufactured or compatible cartridges without the "Cartridge Problem" error.
Cost Savings: Non-HP ink can be up to 70% cheaper than OEM options.
Reduced Errors: Newer firmware often includes aggressive "Supply Problem" triggers that can disable the printer even with genuine ink. Full Control: You decide when to update, not HP. Preparation Before You Start
Downgrading firmware carries a small risk. Follow these steps to ensure a smooth transition:
Check Current Version: Go to the printer’s control panel, select Setup > Service > Firmware Revision.
Disable Auto-Updates: Before downgrading, navigate to Settings > Printer Maintenance > Update Printer and turn off "Auto-Update."
Use a USB Connection: Firmware transfers are much more stable via a USB cable than over Wi-Fi. Step-by-Step Downgrade Process 1. Source the Correct Firmware
You need a firmware version released prior to the 2016/2017 "Time Bomb" updates. Look for version PNP1CN1545AR or similar. Since HP removes these from their official site, you may need to source them from reputable third-party printer technician forums or ink suppliers. 2. Enter Service Mode
If the printer is "locked" by an error, you might need to initiate the update through the OOBE (Out of Box Experience) or Service Mode. Turn the printer off.
Press the "Back" arrow button four times (even if it's not lit) to enter the Support Menu. 3. Run the Firmware Updater Connect the printer to your PC via USB.
Run the .exe (Windows) or .dmg (Mac) firmware file you downloaded. Select your HP 8620 from the list of devices.
Click Update and wait. Do not turn off the printer during this process. 💡 Pro Tip: Disable "Cartridge Protection" Firmware updates often introduce new bugs that HP
Even with older firmware, HP has a feature called "Cartridge Protection" that locks ink chips to one specific printer. To prevent future headaches, go to the printer’s web interface (type its IP address into a browser), navigate to the Settings tab, and disable HP Cartridge Protection. Troubleshooting Common Issues
Printer Not Found: Ensure you are using a high-quality USB cable and that no other print jobs are in the queue.
Update Failed: If the update stalls, restart both the computer and the printer, then try a different USB port.
Still Not Recognizing Ink: After downgrading, you may need to perform a "Hard Reset" by pulling the power cord for 60 seconds while the printer is on.

Risks: Downgrading is not officially supported by HP and carries a risk of "bricking" (permanently disabling) the printer.
Alternative: HP sometimes releases "remedy" updates that officially allow third-party chips without needing a full downgrade. Check the HP Support site first for any optional "remedy" firmware.

is a common tactic for users looking to bypass "Dynamic Security" updates that block non-HP or refilled ink cartridges. While HP officially states that downgrading is not possible or supported, many users find it "better" because it restores the ability to use more affordable third-party supplies. Why Downgrade?
Third-Party Ink Support: Recent firmware versions (like FDP1CN2022AR) are designed to recognize and block cartridges with non-HP chips. Reverting to an older version (such as 1910A or 1416) typically removes these restrictions.
Cost Savings: Using compatible or remanufactured cartridges can significantly lower printing costs compared to genuine HP ink.
Fixing "Damaged Cartridge" Errors: Firmware updates can sometimes trigger false "damaged" or "problem" cartridge messages on perfectly functional third-party units. How to Downgrade (General Steps)
