N900 Cant access the modem. - maemo.org

Dimand · #1 2011-09-19, 08:07

There are many other threads on this topic. Most of them are under the name of sim card failed etc where the user is experiencing a lack of cellular connectivity and a sim card with a bar through it. Sometimes this is just a problem with the sim card, in this case, the sim card is fine.

Here is some background on the bug:
https://bugs.maemo.org/show_bug.cgi?id=10307

Now i'm here to discuss this and hopefuly find a solution. I am fairly tech savy so lets hope i can easily do anything that people suggest. I am also determined to fix my N900.

This MAY be a hardware problem. It does seem to happen more in warmer situations. however, I have had my phone to pieces and all connections are good and heatsinks are clear and free of fluff. Here is a good quote from the bugtracking thread as to why i believe this is a software issue:

Quote:

Yes, this could be an HW issue but:

1) many ppl are experiencing the very same issue. that's strange. That would mean that a certain amount of N900 have been shiped wot faulty hahdware. Bad.

Here is Maemo Talk thread
http://talk.maemo.org/showthread.php...ight=sim+error

2) the modem is working perfectly while on 2G and once a 3G connection is established error won't happen. If that was a faulty HW issue I'd assume resets would still happen while connected.

3) I already reflashed both with 1.1 and 1.2. Issues are VERY less frequent on 1.2. Again, if that was a HW issue, problems would have been still there.

4) Modem resets are more frequent while on some spefic cell towers. If that was a HW issue, resets shouldn't be related to network location.

Now, I have system logs that show the events that occur.
If i am on a call and start using other applications i get disconnected, however the modem reconnects very soon after.

However, say the phone is in my pocket. sometimes the modem will start cycling disconnects and then disable the modem giving the characteristic, all telephone functions disabled and bard sim card message.

This phone was re flashed only a week ago. made little to no difference. The problem appeared gradually. the symptoms are very similar to others.

I will upload a full log dump when I get home.

Please respond to my cry for help!

Hi. few days bak i faced the same issue.
Seems like nokia care ppl had forgotten to fix one of the screws.
and this screw was from the antenna. So remove the back cover and check if all 6 screws are in place and tightly secured.
If yes then there must me some loose connection or dust between the points on the antenna and the point on the main board.
Also check if all the SIM connection pins in the sim card slot are at the same level.

HTH

Dimand · #3 2011-09-19, 09:42

I bent the pins on the main board up last time I had the cover off to give me a better connection to the GSM antenna module (the one located on the far side from the camera) however the receiving contacts were quite worn. I lack the capabilities to re-plate them with gold but a small lump of lead based solder should let me guarantee that I am getting a good connection to the antenna.

I will let you know how I go. Was this issue giving you similar syslog errors?

I think one of the issues here is that a wide range of problems will give you this very common error. I plan to keep going through them till I find the right one.

Omkar · #4 2011-09-19, 10:14

I never checked the sys log errors.
The SIM was detected at the time of booting. but sometimes i would get an error message "all telephony functions disabled".
If i removed the bak cover and apply some pressure on the antenna at boot time this error would go.

Dimand · #5 2011-09-19, 13:10

Ok, fairly sure this is a case of same symptoms different problem.

I removed the cellular antena and booted the device. NO ERRORS! This is not actually surprising. The phone simply assumed that I had no signal, there is no difference to the modem if it sends a request and either a, there is no one to reply or b the request never made it. Obviously the modem doesn't check radiation impedance to make sure there is an antenna there, that would be mostly useless.

Anyway, I reinsert the antenna with device still powered on. About 5 seconds later i have signal. Here is the syslog of this event:

Now, I removed and reinserted the antenna multiple times, same thing, no issues. just like going in and out of signal. Here is the Syslog event of taking out the antena:

Still looking for as much help as possible and thank you Omkar for the suggestion, but I believe this is not my problem.

Omkar · #6 2011-09-19, 15:43

my usb had come out for the 15th time now

.. so its bak at the repairs. i dont have warranty so gave it to a private technician.
hope it comes bak fit and fine. and hope it doesnt have the antenna problem...
would try the syslogs once i have my phone back.

AW wish u good luck with solving prob with your phone..

Dimand · #7 2011-09-20, 05:59

As a side not, I am currently using the Global firmware. Could this cause an issue. The original location of my phone is not know, my friend brought it in Singapore about 2 years back.

Is it worth flashing other firmware to see if that fixes this issue?

abill_uk · #8 2011-09-20, 06:40

You said you flashed the device but you never said if you flashed BOTH images, if you have checked the hardware for loose whatever and you have flashed BOTH images then you have 2 choices basically.

The global image is fine, it works same for everyone.

If your not prepeared to take this to Nokia care then you will have to use a magnifier as a start and check for any dry joints, cracks or broken components.

If all is ok then you must download the service manuals and you will need the right equipment to do all the tests that are all written in the service briefs.

Dimand · #9 2011-09-20, 11:44

It is good to hear that the global image is fine.

I have flashed both images.

As for nokia care.. How much would that end up costing me in time, shipping and the plain cost of fixing it? More than the cost of a new phone? It would probably get close close. Also, It seems in this case they usually just replace the phone, meaning it is probably not worth fixing...

You seem to think that this must be a hardware problem. I have read both service manuals for this device. I don't have the tools needed to debug the phone such as they use in the higher level service manual. Cracked solder joints are a possibility. I might well give the main board a run over with the heat gun tomorrow, see if that helps.

I'm still looking out for anyone with any insights into this. Help me out here.

Did you solve your problem with the modem?
