HP LaserJet Pro M14-M17 Printer series Firmware update stucked the printer

[MPostak]

As reported in other similar issues, I tried to update the Firmware of my HP LaserJet Pro M14-M17 Printer.

The update run through wifi, following the instructions provided by the manual and the update software.

 After restarting the printer, the on/off and cancel button are blinking simultaneously.

The printer can now not be seen anymore, neither if connected through USB cable, nor through WiFi.

I tried to perform the suggested resets (unplugging the power cable and press cancel and power button), but the printer still remains in a non-working status.

I've seen from other posts that you may be able to provide additional information.

I am sincerely disappointed with this issue, since the error occurred after carefully following all instruction and instruments officialy provided by HP.

Hi @MPostak,

Welcome to the HP Support Community

I understand you are facing an issue with your HP Printer. Not to worry I will help you to get a resolution to resolve the issue.

We have to perform an NVRAM Reset to unlock the features of the printer/Reset the password. 

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.

Hi, unfortunately the NVRAM reset does not help...
After a while the "on/off" and "cancel" leds keep blinking simultaneously. 

The printer is not detected in windows (I also checked in the device manager) if connected through USB cable.

For this reason, I can not perfrom the firmware update again using the software provided by HP (since there is no printer to be selected in the menu).
