I tried flashing the default, Nokia's:
...using the -M argument, which I supposed should be working fine (correct me, if I'm wrong). I was doing it as part of standard reflashing procedure, after purchasing the device and testing all it components. The only difference is that I've tried, for the first time, to do it all with 0xFFFF instead of closed Nokia's flasher.

I'll fiddle with manually flashing the cmt images (after I find out how to extract them from regular image .bin ), if you're sure that it will help.
