Is there any way to Raw Read cmt of an existing workig N9 ? Is cmt accessible through /dev or /proc ?

I can probabbly strip the cmt from downloaded binary image. Then I'll compare with mine.

dd if=/dev/mtd6 of=/home/user/MyDocs/mtd6_content

(assuming that MTD6 is the correct partition, it's labeled "omap2-onenand". Could also be you want MTD2, which is "config")

I read mtd6. I expected there will a string containing exact version name of current software running in cmt. But I didn't find any such name matching the file name. Any hints ?

there is no read access to cmt from kernel and/or userspace, so you will never be able to read it.

Yes, when I thought about this a bit longer I realized there's really no need for that, of course the cmt can be flashed to the modem controller via access bus (GPIO or whatever) and it needs not be visible to the OMAP memory at all

I made mistake thinking that this was about drivers, I did not think you meant the modem SW. Silly me for thinking it should be there on mtd...

BTW, why would you need to know anything about it, it's binary object anyway... I'd like to get the source but that's not going to be available, ever

I saw /dev/cmt is not a file, its a directory, there is cmt_en inside. and I didn't find anything meaningful inside that directory. What I want is to know is where to check which cmt version I am using.

No, you are mistaken now
the /dev/ hierarchy is kernel drivers, absolutely nothing to do with modem firmware

I am also interested to know if there is any way to know cmt version and overwrite original cmt version again. My N9 shows IMEI when I put it in flight mode and as soon as I put SIM in, IMEI number disappears.
