Thank you! But it wasn't that difficult once I compared the firmware
to other m920x's ones ;-)

I'll wait impatiently ;-)
BTW it would be interesting to have another firmware for the same
device, could you please extract it from your capturer using the
tweaked script (if you have the time, of course, and a windows system
near you -- or a backup of the snoopy logs), and post it, or make a
diff and post the results? In any case it's not crucial, I'm just
curious, so don't waste your efforts on it if you don't think it would
deserve it.
Apart from the firmware, remember I changed .demod_addres in struct
zl10353_config to 0x0f, but also be aware that I recently did another
change to function mt2060_tuner_attach. Now it looks like this:
----------------
static int mt2060_tuner_attach(struct dvb_usb_adapter *adap)
{
int if1 = 1220;
return dvb_attach(mt2060_attach,adap->fe, &adap->dev->i2c_adap,
&tvgot02q_mt2060_config, if1) == NULL ? -ENODEV : 0;
}
----------------
where you can see I've changed a 0 to a 1220, based on what other
drivers do, when using a mt2060 tuner. In fact, this seems as some
kind of default value, and then they read something from the eeprom to
adjust it. I'm still understanding it, so take a look if you want to
dib0700_devices.c or af9005-fe.c. Anyway, that change seems to give me
a better signal reception.
Finally, for the record, here are some logs I got. To me, it seems
like the device is completely recognized and is tuning fine, but for
some reason /dev/dvb/adapter0/dvr0 is not serving any data. Please,
tell me your impressions.
Regards,
