Title: Why Downgrading the Firmware on Your HP OfficeJet Pro 8620 Is a Better Move (And How to Do It Safely)

If you own an HP OfficeJet Pro 8620, you’ve probably noticed that recent firmware updates have made life harder – not easier. From sudden “non-HP cartridge” warnings to blocked third-party ink and sluggish performance, HP’s latest updates often feel like they’re designed to restrict, not improve.

That’s why many users (including me) have found that downgrading the firmware is a better solution. Here’s why. hp officejet pro 8620 firmware downgrade better

Step 4: Perform the Downgrade

1. In the printer’s EWS (type the IP into a browser), go to Tools → Firmware Update → Manual Update.
2. Browse to the old .bin file you downloaded.
3. Click Update. The screen will go dark. Do not touch anything for 10 minutes.
4. The printer will reboot twice. You will see a progress bar reach 100%.

C. Removing "Feature Bloat"

Newer firmware sometimes adds intrusive "services" or promotional notifications to the printer's LCD screen, nagging users to sign up for HP Instant Ink or warranty extensions. Older firmware typically offers a cleaner, distraction-free interface.

1. Introduction

Firmware updates are intended to fix bugs and improve security. However, for the HP OfficeJet Pro 8620, updates released after 2018 (e.g., versions 1739A, 1759A, and later) introduced Dynamic Security features that block cartridges using non-HP chips. This paper explores why reverting to firmware version 1638A or earlier is considered "better" by many users and service technicians. Title: Why Downgrading the Firmware on Your HP

Step 5: Block Future Updates (Crucial)

After downgrading, HP will immediately try to update again. Stop it:

1. In the EWS, go to Settings → Security → Administrator Settings.
2. Disable Allow Automatic Firmware Updates.
3. Change the DNS server to a non-routable address (e.g., 0.0.0.0) under Network settings.
4. Block these HP update domains on your router:
   • hpfirmware.hp.com
   • firmware.hp.com
   • hpservice.bc.hp.com

Why Older Firmware Is Better

1. Third-Party Ink Freedom – Newer firmware versions actively block non-HP cartridges. Downgrading restores your ability to use affordable, reliable third-party ink without constant error messages. In the printer’s EWS (type the IP into

2. No More “Cartridge Protection” – HP’s Dynamic Security feature can permanently reject certain cartridges. Older firmware doesn’t enforce this aggressively.

3. Better Performance & Stability – Many users report slower boot times, print failures, and scan issues after updating. Downgrading often brings back the snappy, reliable performance you originally bought.

4. No Forced Updates – Older firmware doesn’t nag you constantly or auto-update without permission.

Step 2: Prepare Your Printer

1. Disable the printer’s internet connection. Unplug Ethernet or turn off WiFi.
2. Connect the printer to your computer via USB. Do not use a network connection for downgrades—it increases failure risk.
3. Ensure the printer has paper loaded and at least some ink (even low ink is fine). The printer may perform a reset cycle.
