HP Officejet pro 7740 don´t start after 2020 July firmware update

[lsimoes]

Hi,

Yesterday printer, network cpnnected trough wireless, asked to download and update formware. I said yes.

I gave lots of time for the process to finish, some hours.

But the printer remained stucked in the HP logo and unresponsive.

I followed several suggestions in online HP support, mainly regarding the power initiation, unplug, discharge and plug again, connected the printer using a usb cable and trying the hp firmware update to find the printer, but all with no result.

The HP logo appears as soon as power cord is connected, no need to press the power button. Also is not possible to power off the printer using the power button. There is no reaction to power button.

I can´t find any more suggestions in HP support nor in HP virtual agent.

I think something went wrong during the firmware update process, I don´t know what and there is no error message.

And I can't find a way to perform a firmware update in the current status of the printer. There is only a HP logo in the screen.

Any suggestions?

Thanks,

Leonel
