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.

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.
