Laserjet pro mfp m428dw firmware downgrade

mixibixi · ‎10-25-2022

Please help downgrade laserjet pro mfp m428dw firmware to a firmware before 2208A. Printer got this update and stopped sending emails. We tried to reconfigure it however, it does not work. Another printer with an older firmware works fine. No we cannot use another email service.

HP only has links to a broken newest firmware versions.

You may have to extract the .ful file from the utility using a program like 7Zip and then installing via a USB stick as the utilities themselves typically will not run if the firmware on the device is newer. Make sure you have auto updates disabled or the printer will resort to the newer firmware after a short amount of time.

Thanks. I cannot believe I have to collect printer firmwares now 🙂 I don't seem to have an option to mark your reply as solution but I marked as a helpful answer. Thank you again.
