Raw read N9
 

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")

Re: Raw read N9
 

where can I get a list ? which device points to what ?

Re: Raw read N9
 

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 ?

Re: Raw read N9
 

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

Re: Raw read N9
 

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 :D

Re: Raw read N9
 

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.

Re: Raw read N9
 

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

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.

Re: Raw read N9
 

There is no way to overwrite as downgrade is protected. Your sim slot might also be broken as that part breaks quite easily too. Your only option is Nokia care (even care cannot downgrade, they need to replace the phone with a new one).

Re: Raw read N9
 

Yes, that is last option now for me :( But I was just wondering that how it worked for few days and then stopped now. Because of this I feel it is software issue.(I may be wrong).
Also as I said, phone shows IMEI in flight mode/without sim but as soon as sim is put it disappears.

Re: Raw read N9
 

i'm sure you can reflash cmt from firmware for other country.

Re: Raw read N9
 

hey coderus, thanks for reply. I have tried almost 12 different fw for cmt flash and only chinese cmt were able to flash earlier which now give error.
My phone is of poland, central europe origin.

Re: Raw read N9
 

once you have flashed chinese cmt, you can _never_ go back to european.

People should not blindly try flashing different firmwares, as it just leads to bricks.

Re: Raw read N9
 

People are not doing it blindly. It was reported in these forums as well as meego forum that many have resolved sim error issues with chinese fw(even when they had other original fw). Even I was abe to get it working(somewhat) and now at least I can use it for everything else apart from cellular.
The issue is for many people this SIm error appeared randomly, after restart or update or such reasons.

And AFAIK there is still no way to know which CMT is on so we have to try and find fw till we get any success.

Please don't assume people just flash for fun :)
Just my 2 cents.

Re: Raw read N9
 

I have really hard time believing that you could resolve your simcard errors using one or other country variant :D

It's a placebo, I belive it has been just the action of flashing it that cured the device, rather than what was flashed...

Re: Raw read N9
 

Yes its just enough to know whats your firmware and reflashing with exact same version. You never need to know your version of CMT.

If you have flashed any wrong version like chinense CMT then its just your own fault that you made your device never to accept european CMT firmware. (you can ofcourse just flash everything but CMT and that in most cases gives you a working device).

I would still say that people are doing it blindly, and some 'resolved fixed' suggestions in this forum are just stupid. So if someone suggest that you jump off the cliff, and you blindly follow, then it's just darwinism in action.

And ofcourse there is a way to know which CMT device has, but there is no way in world that I would tell how to.

Re: Raw read N9
 

I guess you have not read what I have written.
I have tried to flash original fw and it didn't resolve issue with SIM error. That is exactly reason why I have tried other fw including chinese ones.
ONLY chinese one appear to have fixed it first. Initially my phone worked for few days. Now also it is working without cellular functions, much better than SIM error and phone being unusable.


There are many people like me who faced exactly same issue. For some they had flashed other regions fw but for some this error has appeared without any reason. Like after updating sw via sw update on phone or one fine day they restarted phone and this error showed up.

Hence do not think that you know everything and other's are blind followers. People will try to find resolution by trying what has worked for others after they have exhausted all other logical options.
