Re: nokia n9 IMEI random erase
 

Hopefully you never tried to flash 280 version, since if you did then you can never go back to 006, that would explain why mcu sw flashing fails.

Re: nokia n9 IMEI random erase
 

But that's not the case. If That was the scenario I couldn't even flush the rootfs I believe. and was supposed to show 280 instead of Then what can be the problem with mcu sw ? I am not getting any hints :(

Re: nokia n9 IMEI random erase
 

Well there are 2 possibilities, if modem harware is broken, then mcusw flashing fails, or the other possibility, if you have tried to flash any other (ie wrong number) firmware even once, then then its overwritten mcusw with too new mcusw timestamp, and all the subsequental flashes to 006 will fail (because downgrade of mcusw is never allowed).

Re: nokia n9 IMEI random erase
 

How will I confirm which one of these two possibilities have occurred in my case ? as I can boot in Can I send any commands to cellular modem through terminal to check what version its using (though I don't remember I've ever done that. but still good to have a check) ? or if its broken.

and as flasher -i is reporting 006 doesn't it mean that cmt is also using 006 only ?

Re: nokia n9 IMEI random erase
 

What about trying to flash with variant 280 (if it's a suitable variant for you) ?

Re: nokia n9 IMEI random erase
 

checked my .bash_history , there is no reference of 280. I've checked all flasher commands that I've ever invoked. and none of them have 280. also I saw I never downloaded 280.

I have only 3 files in My downloads folder

Re: nokia n9 IMEI random erase
 

So Geeks. No Solution ?

Re: nokia n9 IMEI random erase
 

I have exactly same issue and you can refer to my posts in this thread.
http://talk.maemo.org/showthread.php...28#post1305428

I have made some progress by trying few things which you can see in latest posts in that thread.
I am still trying to find complete solution.
Please check if those posts help you in any way.

Re: nokia n9 IMEI random erase
 

But I don't see any hint to track. Now I've started to think, its a hardware issue. and The problem is there is no way to make sure. where the problem is. as bootloader can pick up my imei correctly. and I can see it in /proc/cmdline.

Re: nokia n9 IMEI random erase
 

I think that at some point, firmware versions have been mismatched on-device.

Using the PR_LEGACY 006 firmware, add "--flash-only=rootfs" to the end of that command line, and on the second run to flash the eMMC, remember to have "--flash-only=emmc".

Don't reboot yet.

Now download the PR1.3 PR_LEGACY 280 rootfs, and "--flash-only=cmt-mcusw".

You should now have a device with PR1.3 006 on the APU, and PR1.3 280 on the MCU (and the MCU's swcert should match with the MCU firmware)

(IIRC mismatching APU and MCU firmware is allowed. In case you get a MALF, flash the PR1.3 Open Mode kernel and follow these instructions)

Re: nokia n9 IMEI random erase
 

As I said I also got exactly same issue but after flashing chinese cmt only my phone shows IMEI and works sometimes (50% of times)
So I don't think issues is with hardware.

Re: nokia n9 IMEI random erase
 

Many Thanks for reply.
Can you please explain "Now download the PR1.3 PR_LEGACY 280 rootfs"

I could not understand what rootfs is? Or is it just typo?
Do you mean to download this file?
Dfl61 Harmattan 40.2012.21-3.280.04.1 Pr Legacy 280 Arm Rm-696 Prd Signed.bin

Is file is from same product code which is mentioned at back of SIM tray?

I got following error

So I used cmt option as specified in fflashing post, but I got following error.
Then I tried chinese cmt and it was finishing at 75% for cmt-mcusw before giving following error.

Re: nokia n9 IMEI random erase
 

That's quite the odd problem.

Your device has PR 003 firmware and has Chinese CMT firmware.

And flasher -i shows all the information properly, yet Harmattan can't seem to talk to the BB5?

At this point I'd be inclined to install the Chinese firmware to match, but the Chinese firmware sucks. (Don't do it yet!)

Perhaps other forum members can get your 003 firmware device talking to your CMT.

Re: nokia n9 IMEI random erase
 

Many Thanks for reply.
After this recent cmt flash , error showed as as shown in log but earlier cmt only flash with chinese fw used to give success. i am not sure if this means anything.
Also I noted very strange thing. When I don't put SIM in tray or put phone in flight mode , it shows IMEI in About->settings
But as soon as i put SIM card it disappears.

Earlier when chinese fw smt flash used to be successful, it used to work 50% of times and then suddenly lose network.

Re: nokia n9 IMEI random erase
 

Have you tried it with another simcard, does the behaviour change?

Re: nokia n9 IMEI random erase
 

Yes, I tried with 3 different SIM cards from 3 operators and still same issue.

Re: nokia n9 IMEI random erase
 

What I am fearing is.flasher -i is reporting I've 006. Now If I flush CMT with 280 and that doesn't work, wouldn't it block downgrading CMT in future ?

So is there any way to know which version cmt is running ? (If cmt and rootfs run two different versions)

Re: nokia n9 IMEI random erase
 

Yes, I would also like to know if there is any way to find these base software details currently being used on phone.

Anyone?

Re: nokia n9 IMEI random erase
 

well what version its using you can find with flasher. But as Some people mentioned above CMT may have a different version. The question is How to know what version CMT is using.Is there a way to raw read cmt or mcusw ?

Re: nokia n9 IMEI random erase
 

I am also talking about same , I meant base software = cmt etc.

Re: nokia n9 IMEI random erase
 

I've tried to flash cmt using 280 version BUt that also failed.
ERROR: SU_GET_UPDATE_STATUS_REQ terminated with error code 1: Unknown error

Su_get_update_status_req
 

What does this mean ? I've searched But never found any defines for this.

Re: nokia n9 IMEI random erase
 

Afaik flasher is asking status of how the update went, and unknown error happens if modem hardware is broken, if you try to downgrade firmware or to change it to different region.

Re: nokia n9 IMEI random erase
 

How to make sure, which one of these three possibilities has happened in my case ?

Re: nokia n9 IMEI random erase
 

there is no way to know, you can roll the dice and decide yourself. Unknown error is unknown. My bet is that hardware is broken.

Re: nokia n9 IMEI random erase
 

Thanks fro the rare clear answer. I've heard that its not possible to desolder/repair the cmt only without changing the complete board. Is that True ? or Nokia Care Lied to me ?

Re: nokia n9 IMEI random erase
 

well one question. if hardware is broken should I get imei in /proc/cmdline ?

Re: nokia n9 IMEI random erase
 

or if i can see IMEI when in flight mode? How do we know for sure it is hardware issue?

Re: nokia n9 IMEI random erase
 

I believe when in flight mode it doesn't communicate with modem hardware at all

Re: nokia n9 IMEI random erase
 

Yes, but how it loses IMEI when not in flight mode?
Something is triggering to check that disable. I hope we could know how and why it is happening.

Re: nokia n9 IMEI random erase
 

Yesterday my phone was working fine however while it was connected to my workstation in office just for charging. (I charge it in office from day one june-2012) However when I unplugged it i started getting the same error as the Suyog & neel.basu is getting.

Is anybody able to find out a way to do so? :(

Re: nokia n9 IMEI random erase
 

1 June 2012. what a date.
solutions exist. but all don't work always.

Re: nokia n9 IMEI random erase
 

my PR number is 299 (Australian variant), as suyog suggested I tried to flash cmt only from chinese variant (16GB Black) but no use.

Just some added information and assumption on the basis of my understanding.

I assume that the issue is due to the mobile is unable to retreive the IMEI number.

Basis: Any Nokia Application is not working correctly which I guess need IMEI number to register. For e.g. Unable to set Nokia account under Accounts & Nokia Store. So I rule out the chances of HW issues related to SIM.

Also, as I m able to see the IMEI number using "cat /proc/cmdline" so I suppose no hardware fault there.

So the whole issue is due to IMEI number not retreived. May be I m wrong but I will be more than happy if someone can enlighten me with the whole issue. Please note that I have read all pages of this thread and Reflashing guide so don't think I am writing without searching and reading.

Also, all this happen when my phone was working and getting charged through my office desktop and suddenly the world standstill. :( :(

Request to all geeks.. please have a look into it... since yesterday I came to know that many people are facing this issue and the number is increasing day by day.

Re: nokia n9 IMEI random erase
 

Well I don't know, rather I am doubtful whether IMEI and comes from CMT hardware or not. If IMEI comes from a different hardware or if bootloader doesn't need to have any communication with CMT to pass the imei. then there still may be a hardware issue. I asked the same in one post.

Re: nokia n9 IMEI random erase
 

@kumary . welcome to unique club :)
Please flash chinese variant cmt or whole as last option.
I am sure you have tried flashing aussie version with zerorize option.
Try to flash again , may be with european fw.

Sometimes I wonder if Nokia(Elop???) put some trojan to break functionality :)

Re: nokia n9 IMEI random erase
 

I flashed the chinese CMT but as usual its not working.

I m really pissed off.. I came to know that changing the motherboard might help all of us. But its not available so easily. :( and its costly too.

But now I am free test anything to everything on my N9.

Hey I got most expensive Ipod ;)

Also, few more details on the issue... Phone getting hot very quickly, like while charging and rebooting as well. Also the phone getting very hot on upper right corner where the Sim card slot is.

I guess its hardware issue now. :(

Re: nokia n9 IMEI random erase
 

kumary,

Why did you flash Chinese CMT? Can you explain what problem you exactly had as well as your previous firmware version numbers? Did you flash Chinese CMT before?

Re: nokia n9 IMEI random erase
 

I always flashed only one firmware

E10C8FCB_DFL61_HARMATTAN_40.2012.21-3.299.1_PR_LEGACY_299_ARM_RM-696_PRD_signed

This is selected basis the model number which is 059L698 from Navifirm. I downloaded it earlier.

As you read in my earlier posts, the phone was working alright and I put it on charging as usual after a call. Later when I removed it from charging I was not able to dial any number and in settings there is no option available under network settings.

While I reboot the phone it shows error that the sim is not working. Also, I tried the above mentioned firmware thrice (its the original firmware with which I get the phone.)

I tried flashing the Chinese CMT without success. I tried it based on the Suyog research and his posts in the N9's comprehensive flashing guide post.

From the above I can confirm my phone uses firmware number 299 (Australian) and I understand I can't flash to lower firmware like 003 for china.

But I am trying all the possibilities. If you have any idea then pls help. Also I have not included other details which I have mentioned in my other posts in this thread.

I am open to all suggestion to make it work. :(

Re: nokia n9 IMEI random erase
 

So you always had Australian firmware and yet flashed Chinese CMT? Why on earth would you do that??

Despite your issues it makes no sense for you to flash Chinese CMT! suyog's "research" is something for his own device...

I'm afraid by flashing chinese cmt you have got yourself into a bigger mess...

Re: nokia n9 IMEI random erase
 

I agree... but its not working either way :(

and chinese CMT failed and unable to flash... so I haven't successfully flashed it. Do I have any hope for the device?
