[Q] Changing Modem only to LRK from 412

For me in UK Virgin Mobile the Modem in LSZ 412 is awful..

Is it possible to change the Modem in LSZ (412) back to XXLRK Modem from XXLRQ 404 in PC ODIN.. Is it available as a seperate download.

When I was using the S2, I just put the Modem (in this case LRK) into PDA of PC ODIN and flashed > Rebooted and it was fine.. No wipe, Is that still the case on the note.

Thanks
