I've changed those parameters an tried again, but no luck.
Scanning report is similar:

Firmware on this card is in an eeprom, so I think that I cannot update it.
I've tried to put dvb-fe-tda10046.fw file on /lib/firmware/, expecting
that this file could override the eeprom one when system is running,
but tda module loads always the eeprom firmware.

Thanks
