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"
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.
Downgrading the firmware on your HP OfficeJet Pro 8620 is primarily done to bypass "Dynamic Security" or "Ink System Failure" errors that block the use of third-party or refilled ink cartridges. While HP generally states that downgrades are not supported for security and quality reasons, users often seek older versions to restore compatibility with more affordable ink alternatives. Why Downgrade is "Better"
Third-Party Ink Support: Newer firmware updates often include "dynamic security" features designed to block cartridges that do not have an original HP security chip. Downgrading can re-enable the use of these cost-effective alternatives. A sample of 50 HP OfficeJet Pro 8620
Fixing False Error Messages: Updates can sometimes cause printers to incorrectly identify cartridges as "damaged" or "depleted". Reverting to an older version can resolve these software-induced hardware blocks.

Why Downgrading Your HP OfficeJet Pro 8620 Firmware Might Be a Smarter Move
The HP OfficeJet Pro 8620 has long been a workhorse for home offices and small businesses. It’s fast, reliable, and produces high-quality prints. However, many users recently found their printers "locked" or refusing to recognize perfectly good ink cartridges. The culprit? An automatic firmware update.
If you’re frustrated by "Cartridge Problem" messages or "Non-HP Chip" errors, you aren't alone. For many, performing an HP OfficeJet Pro 8620 firmware downgrade is the best way to reclaim control over their hardware. The Problem: HP’s "Dynamic Security"
HP frequently pushes firmware updates that include "Dynamic Security" features. While HP claims these updates protect the quality of the printing experience and prevent piracy, the practical result for users is often the "lockout" of third-party or remanufactured ink cartridges.
If you prefer using more affordable, eco-friendly third-party inks, a recent firmware update can effectively turn your printer into a paperweight until you buy expensive, genuine HP supplies. Why Downgrading is Often "Better"
Freedom of Choice: Downgrading to an older version of the firmware removes the strict DRM (Digital Rights Management) checks. This allows you to use third-party ink cartridges again, potentially saving you 50-70% on printing costs.
Stability: Sometimes, new firmware updates introduce bugs or slow down the printer’s interface. Reverting to a "tried and true" version can restore the snappy performance you’re used to.
End of "Cartridge Rejected" Errors: If your printer was working fine yesterday and stopped today after an overnight update, a downgrade is the most direct fix for those sudden "Supply Problem" alerts. Things to Know Before You Start
Before you attempt a firmware downgrade, keep a few things in mind: Find Previous Firmware Version:
Risks: There is always a small risk when messing with firmware. If the process is interrupted (e.g., a power outage), it could "brick" the printer.
Warranty: If your printer is still under warranty, HP might claim that a manual firmware change voids it.
Connection: It is highly recommended to perform the downgrade via a USB cable rather than Wi-Fi to ensure a stable connection. How to Downgrade Your HP 8620 Firmware (General Steps)
While the specific files change depending on the version you need, the general process involves:
Find the Older Firmware: You will need to source an older version (typically versions from 2014 or 2015 are the most "open"). These are often found on community forums or archival sites since HP doesn't host old versions on their official support page.
Prepare the Printer: Ensure the printer is on and connected directly to your computer via USB.
Run the Installer: Open the firmware file on your computer. It will look for connected printers. Select your OfficeJet Pro 8620.
The Transfer: Follow the on-screen prompts. The printer's screen will usually show a "Programming" or "Updating" message. Do not turn off the printer during this time.
Disable Auto-Updates: Once the downgrade is successful, the most important step is to go into the printer’s settings (on the touch screen) and Turn Off Auto-Updates. If you don't, the printer will simply download the restrictive firmware again within a few days. The Final Verdict
Is an HP OfficeJet Pro 8620 firmware downgrade better for you? If you are a high-volume printer who relies on third-party ink to keep costs down, the answer is likely a resounding yes. By rolling back the clock on your software, you bypass the "Dynamic Security" hurdles and return the printer to its original, more flexible state.
HP will tell you that downgrading violates your end-user license agreement (EULA). They argue that security updates protect against remote exploits.
But here is the counterpoint: You own the hardware. When you bought the HP OfficeJet Pro 8620, you paid for a physical device. HP’s firmware updates after the sale fundamentally change the functionality—specifically, blocking third-party ink that worked at the time of purchase.
In the European Union, consumer protection laws have challenged such practices. In the US, the “Right to Repair” movement supports firmware downgrades as a legitimate repair tool.
If you do not use HP-branded ink, you are not harming HP. You are simply using your printer as you originally intended.
The HP OfficeJet Pro 8620, a widely used all-in-one printer, has experienced progressive firmware updates that prioritize security and supply authentication over user flexibility. Many users report degraded functionality, including rejection of third-party ink cartridges, slower performance, and reduced feature access. This paper investigates the benefits, risks, and procedures of downgrading the printer’s firmware to an earlier version. Empirical evidence from user communities and controlled tests shows that firmware downgrade can restore third-party ink compatibility, improve print speed, and re-enable local control features, enhancing overall user satisfaction.
