M277nw error 79 after firmware upload - info to downgrade firmware

[ArthurAshby]

Does any one know how to downgrade the firmware of a printer MFP M277dw to a previous one (i.e. 20201119)?

I  have one M277dw HP printers that after the update of the firmware can not scan to a shared folder (every time I try to scan printer is starting to 79 service error and does a reset).

So I want simpy to downgrade but cant find the old firmware update utility.

On the printer there is an option to "allow downgrading" but there is no way where I can upload the old firmware on the printer. So the only two options it to find the old firmware update utility.

Thank you

Hi @ArthurAshby

Welcome to the HP Support Community. 

I understand that you are getting error 79, I'd like to help!

Follow the steps below. 

One of the following errors is displayed on the printer's control panel:

79 Error Turn off then on

The printer has experienced an internal firmware error.

79 Service error Turn off then on

An incompatible DIMM might be installed.

Solution: 79 Error Turn off then on

Turn the printer power off, wait at least 30 seconds, and then turn the power on and wait for it to initialize.

If you are using a surge protector, remove it and plug the printer directly into the wall socket. Turn the printer power on.

If the message persists, disconnect any network or USB cables and power cycle. If the printer returns to Ready, check the firmware version and update if a newer version is available.

For instructions on updating the firmware, go to HP LaserJet Pro - Update the printer firmware.

NOTE:

The firmware version can be found by printing a Configuration Report from the control panel of your printer. Visit the HP Customer Support Drivers page to find the latest firmware version available.

If the error is intermittent, attempt to isolate the issue to something specific in your environment.

Delete all print jobs from all computers connected to the printer and send a simple test print job.

If the message persists, please contact HP Customer Support.

Thanks for answer but  every time I try to scan to shared folders printer is starting to 79 service error and it does a reset, but this one ONLY AFTER THE UPDATE of firmware.
So I think the problem is the new firmware (before update I usually scan to shared folder)

Hi @ArthurAshby,

Thanks for your reply. Let us do the reset and see how it goes. 

The reset instructions are specific for your printer and performing those steps on a different printer may brick the device.

I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer.

In order to access your private messages, click the private message icon on the upper right corner of your HP Support Community profile, next to your profile Name or simply click on this link.
