HP OfficeJet Pro 8620 — Firmware Downgrade (New)

Warning: Downgrading printer firmware can brick the device, remove features, or void warranties. Proceed only if you understand the risks.

💡 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? hp officejet pro 8620 firmware downgrade new

HP has learned from the 8620. They have patched most downgrade exploits. While the "Rename Trick" and USB methods work for some units manufactured before 2020, newer 8620s (late production runs) have soldered ROMs that reject the rollback permanently.
