How do I flash a modem for CyanogenMod / CM10.2? I have already flashed the latest nightly (as of this time) and the corresponding gapps for my Samsung Galaxy S4 via CWM. But when I checked the Phone settings (About Phone), Baseband version is Unknown.

I have already tried flashing I9505XXUEMJ7_MODEM.tar via Odin (as Phone), but the Baseband is still Unknown.

What am I missing here?
I know this doesn't solve your problem of flashing a Modem via Odin, but have you had a look at the Collection of CWM modems, e.g. here

There is this hint:

Use Odin v3.04
Untick Autoreboot
Flash modem
Reboot once again into Download Mode using (Vol Down plus Home button combi)
Flash Modem once more
Once done,unplug then reboot device manually.
If this doesn't work, try repeating the flash process again while rebooting manually and with auto-reboot option turned off.
