m15w attention and ready lights blinking after firmware update

[bkleiber]

I just set up the printer and unwisely updated the firmware.  Now the printer is unusable as both attention and ready lights are blinking.  I saw this exact question answered in 2019 here:  https://h30434.www3.hp.com/t5/LaserJet-Printing/M15w-blinking-attention-and-power-lights/td-p/698622...

Please let me know what to do next.

Thank you.

Thank you for offering a suggestion.  I tried this several times without any effect.  The printer appears to be bricked.
