Fiat 334 VP2 ECE not work-only logo

[Hack01]

Hi,

You have a Fiat 334 VP2 ECE radio here. It won't turn on on the table until after a while and only the logo will appear.
Can anyone advise where to look for a solution? does anyone have functional flash content?

SW-Version 08.05.08.00

I have reprogrammed the contents of the NOR Flasch 29W256 with content from the functional radio of the same designation and still only the logo and nothing more is displayed.
Advise where to look for a mistake?

The radio requires CAN frames to turn on.

Yes, but it has to write on the display. But this faulty radio will only show the logo and nothing more.
