Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand your HP LaserJet Pro MFP M28w printer is stuck in a state where it’s defined as “hp rbx boot” after a firmware update, it might be in a recovery mode due to a firmware issue. 

Here are steps you can try to recover your printer:
 

1. Power Cycle the Printer

• Turn off the printer using the power button.
• Unplug the printer from the power source.
• Wait for about 30 seconds.
• Plug the printer back in and turn it on.

2. Perform a Hard Reset

• Turn off the printer.
• Hold down the Power button.
• While holding the power button, unplug the printer.
• Wait for about 10 seconds.
• Plug the printer back in while continuing to hold the power button.
• Release the power button once the printer starts to boot.

3. Try Reinstalling the Firmware Update the firmware on an HP printer

• Ensure that you have the latest version of the firmware for your model.
• Download the firmware update file from HP's official site to ensure it’s not corrupted.
• Follow the instructions provided by HP for installing firmware. Typically, this involves running the update file on your computer while the printer is connected.

4. Use HP Smart or HP Support Assistant

• Open HP Smart on your computer.
• Select your printer and go to Printer Maintenance or Settings.
• Look for an option to update the firmware or restore factory settings.
