[Q] Is it possible to downgrade from baseband I9195XXUCOD3 ?

I have recently updated to a 4.4.2 firmware from BTU region with baseband I9195XXUCOD3. I now want to install a firmware from ROM region but the latest baseband available with firmwares for this region is I9195XXUCNK1.

So when I flash the ROM firmware, the baseband does not get downgraded and this breaks the Wi-Fi. I guess the slightly older firmware cannot use the latest baseband version.

So is there any way to downgrade the baseband?

Thanks
