you should prefer dvb-apps from mercurial, but that is not so important.

First of all I would like to see relevant "dmesg" stuff for the card
and tuner to see if it is still likely the same card, auto detected and
eeprom content unchanged and all chips alive. If you enable i2c_scan=1
you look first for the devices found.

Also we never saw, if your firmware upload is successful and if you use
preferably revision 29 with such a card with Low Noise Amplifier.
If not, download it from LifeView with the script in /Documentation/dvb
and do a cold boot. (recent stuff is in a v4l-dvb mercurial snapshot)

Antenna input for DVB-T is FM/RF input.

Can you point to the initial tuning file you are using or to what you
believe is a valid channels.conf file for you?

It is always worth a try to set all to AUTO in the initial tuning file,
except frequency to tune and bandwidth and then use "scan" to create a

If still not, we install the recent v4l-dvb, remove all old modules and
might try to debug from there.
