HP should offer a "legacy mode" for users who accept reduced security in exchange for third-party ink use.
For mission-critical environments, stay on newer firmware but accept higher ink costs.
Always maintain a backup printer when attempting downgrades.

4. Step-by-Step Downgrade Procedure

Disclaimer: Follow these steps at your own risk. Improper firmware flashing can "brick" (permanently disable) the printer.

Step 1: Note your Current Version Print a Printer Status Report from the printer's control panel (Setup > Reports). Look for the "Firmware Version." Ensure you are downloading a version older than what is currently installed.

Step 2: Prepare the Printer

Turn on the printer and ensure it is idle (not printing or scanning).
Connect the printer to your computer via USB.
Crucial: Remove any network cables (Ethernet) and disconnect the printer from Wi-Fi temporarily if possible, to ensure the computer communicates strictly via USB.

Step 3: Run the Downgrade Utility

Download the older firmware utility file (e.g., OJ8620_R1935A.exe or similar naming convention).
Right-click the file and select "Run as Administrator."

Downgrading the firmware on your HP OfficeJet Pro 8620 is primarily done to bypass Dynamic Security

—a feature HP uses to block non-HP or third-party ink cartridges. While HP offers an official update to disable this security lock for the 8620 series, some users still find a full firmware rollback "better" for ensuring maximum compatibility with affordable, remanufactured ink.

: Newer firmware often triggers "Non-HP Chip Detected" or "Supply Problem" errors. Rolling back allows the printer to recognize third-party microchips again. Cost Savings hp officejet pro 8620 firmware downgrade better

: Using third-party or refilled cartridges can significantly reduce per-page printing costs compared to expensive OEM ink. Bypassing Lockouts

: In some cases, firmware updates can completely lock out a printer if it detects a non-genuine cartridge; a downgrade can restore functionality. CompAndSave Official Solution vs. Manual Downgrade

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

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.

Step 2: Prepare Your Printer

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

Abstract:

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.
