CP5525 - Error 99.05.56

Hello,

I've got a Laserjet CP5525n (P/N :CE707A), whith the error 99.05.56.

I update the firmware with EWS. The printer receive the file, but when I click to reboot the printer freeze, with the message the printer is rebooting.

I was changing the formatter and the 8GB drive solid state but the problem persists.

I find nothing on this error.

Can someone help me please ?

Thank you
