Hi guys, good news!
I managed to find a firmware that overcomes the barriers of what HP has introduced for the signature. You can upload lj4700fw_46_130_5 and then the latest firmware.

My first step was the installation of
1 - lj4700fw_46_130_5, followed by error BAD LUCID XX, which I do not know what it meant. After switching off and on again to display the banner RESEND UPGRADE.
2 - I've already uploaded version lj4700fw_180.xx (I think it was unnecessary).
3 - latest firmware. Each firmware lasted about 15 minutes, you have to be patient :).
All through the FTP protocol. Sorry for my english
