My printer has a hard-bricked. it shows a white screen with an option to install a new firmware to get it back to work. I have contacted the customer services asking them to send the firmware but they refused and they told me to send it to the dealer to repair it. Please if you can get access to Sharp firmware page, download the firmware and upload it on Google drive or Dropbox and the link to my email co4321@gmail.com or PM me.

Thanks in advance
