NVRAM issue with my HP Color Laserjet Pro M177fn

[ChC1872]

Hello,

My printer is stuck with the energy star / Hp logo. I cannot push any button, nor print anything. 

It seems to have happened after a software update. How can I restore to factory settings ? I have read all tips on this forum, but no luck... Thanks in advance for your help.

Hi there KrazyToad, 

Thanks for the suggestion, but unfortunately, nothing happened. When pressing both these buttons, then powering on the product, it simply boots, runs the initialization, and finishes with the Eco/HP logo screen and no buttons are responding. It is stuck at this logo screen with no buttons working.

Any other suggestion?

Thanks,
