Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Thanks, I read all the thread, and I saw your problems, but I didn't have all those symptoms and reading all the thread scared me to death.

I have a slightly thin SIM card, with a little bent chip (don't want to change it, costs a lot of money to do that on a business subscription sim card). The thing that makes my sim move is a loose SIM door (that little door you close the sim with), so if the SIM would be a little more thick it would be perfect.

I hope my gsm chip won't get loose like the other users. This device is 2 years old...

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Day 2 after I posted, phone functions are completely dead. I did the following:

- Opened up the device, got my soldering iron, heated up the whole zone (didn't open the shield) by overheating the soldering iron ant touching the schield untill everything became verry hot. Got a tip of a pen and blow with all my force to clean out if any dust is under that shield. Now going to the SIM Reader. I heated up all those points that other user said to hit with a hammer.

- Now, I just added some epoxy to the USB port and connected him by epoxy to the nearby shields, for protection.

- Put it all back together and boot it with a Vodafone SIM. SUCCESS!

- Put back my old COSMOTE SIM and... WORKING.

- Apply some good shocks from every side, even doing some drop tests on the carpet and guess what! WORKS LIKE CHARM.

I attached some pics:

Attachment 31856

Attachment 31857

Attachment 31858

Attachment 31859

Attachment 31860

This worked for me. Now I am testing what really caused the problem. I am going to walk for a while in my house with the phone in my pocket and see if I get the same problem. I will edit this post after a while so I can se if it works or not!

*****METHOD CONFIRMED FOR WORKING!!!*****

I'm glad it's working again with minimum effort!

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Yes. This problem is quite common. I've had three N900's all with same problem. Nokia replaced two of them under warranty but my current n900 is well past warranty age now. I have tried all the methods to fix the problem that are documented in this thread, unfortunately to no avail. The two times Nokia replaced them, they told me that they couldn't fix the problem for me, hence the replacement devices. I still live in hope for a fix. It's gutting, because I always take really good care of my devices.

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Ok, I saw people put some spring and destroyed the shield to get to those parts. Try heating up the shields and press down the shield against the parts. Then heat up all the connectors of the SIM Reader. Do this with a soldering iron, and be sure it's hot like hell! BUT WARNING! Don't even go near the plastic parts!

If this is not working, heat up the GSM chips, press them against the MB, but trough the shield, get some epoxy, and inject epoxy on top of the chips. Then until the epoxy dries up (10-15 mins up to 1h) put something heavy to press it on the MB.

I just fixed mine this way, it's working perfect right now, but I'm going to give it some more time before I can say it really works.

P.S. Didn't use the epoxy on the chip method yet.

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

^^Hey wait dont try the epoxy(assuming its the whitesh or transperent thing that when dries up is rock hard) as it will render it unrepairable for future for correct operations like reheating with paste or reballing it.
And how the hell heating with welding iron came to your mind??? That scared me as hell:o
you better try off the spring thing thats way better then yor current ideas.
Removing or ill fitting sheild is no offence:)

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

And how removing the shield didn't scare you? Heating up works because the chips are made of ceramics, ceramics are heat conductors. Touch with a very hot soldering iron the shield and press against the chip, hold it there for 1-2 seconds and then remove the soldering iron head, and press with your finger even more while blowing cold air. The ceramic transmits the heat, and does the trick to fix some imperfect contacts.

Also my epoxy is not solid rock, it's more like hard rubber. You can still remove it pretty easy.

EDIT: I did this even knowing it's risky, but this is how I fixed my faulty cpu on a SPV mobile phone. I dropped it and half of the cpu unit was detached of the motherboard. I took my soldering iron, a temperature sensor that could take up to 180C. I heated up the chip to 100-110 C for about 1-2 seconds, then blow cold air. After about 10 minutes of doing this, the chip was in place, put it back together and it worked like charm, and it worked until my flex cable to the screen broke and got a new phone. I did the same thing here with the N900, but this time i heated up the shiled, and press it against the chip, so the temperature won't be so high, and until now it did the trick. I don't want to edit my first post yet, because I want to give it more time to see if it works!

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Salut Daniel, nu, din pacate ce postam noi pe aici sunt doar rezolvari temporare. Adica sunt mici fix-uri care sa te mai tina de la 1-2 zile pana la cateva luni. Problema este mult mai adanca decat zgarierea simului sau lovirea lamelelor citirorului SIM. Daca tie ti-a facut asta si inca nu te-ai apucat ca mine sa il stresezi cu pistoale de lipit sau mai stiu eu ce metoda, eu iti recomand sa-l duci intr-un centru de reballing/reflowing (cauta pentri zona ta pe google) si la un pret de 200 - 300 de ron iti realiniaza si relipeste cipul de GSM. Asta e cea mai sigura metoda. Restul metodelor pot duce la deteriorarea acestor cipuri si defectarea permanenta a dispozitivului.

------------------------------------------------------

And now for all of you, the only way to fix this problem is to find a local X-Box service or SONY PS service that fixes the red ring of death problems or stuff like that. Those services can and will do reballing/reflowing processes. Take your phone there, explain the problem, pay the price and return home with a working N900 device.

I wish you luck!

Ahhh, un Craiovean, te salut fratioare. Eu tot craiovean sunt, dar eu sunt mai plimbaret :) si am ajuns prin Bucuresti. Cunosc in Craiova un service care rezolva bine de tot probleme, au si vechime si experienta: http://x-land.ro X-Land se numeste firma, si te-as sfatui ca ma intai sa discuti prin e-mail problema cu baiatul, adica ii trimiti un mail la adresa specificata la contact, poti sa-i trimiti inclusiv cateva poze din cele facute de mine si sa-i explici ce si cum sta treaba si sa-ti faca un pret. Pentru tine ti-as recomanda un simplu reflow, mai ieftin dar nu garantat, iar daca baiatul iti recomanda un reball, mergi pe reball.

Uite e-mailul si numarul lui de mobil: adrian(AT)x-land.ro , 0723.222.282 (sa nu uiti sa inlocuiest (AT) cu @).

Eu l-am gasit pe Craiovaforum si am fost incantat de serviciile lui.

Oricum eu am fost foarte dezamagit de acest telefon, in afata de soft, este foarte prost construit si si-a batut joc de tot numele NOKIA... :( cu parere de rau, dupa ce am detinut 2, te sfatuiesc sa te scapi de el!

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Mersi mult nu stiam de acest service ,cat despre tel nici nu am idee mi la lasat fratele meu acasa cand a venit din Italia mi-a zis doar ca numai primeste cartela am fost o zi pe lipscani cu el si au zis ca nu au ce sa-i faca ,o sa incerc sa ajung la baiatul respectiv zilele astea.
Numai bine

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

yup add it whenever you have time as this idea would save many other phones which deserve it not just n900:)

Ok, I did the paper under sim, worked for a while.
Then had to do the 'hammer' trick, again, worked for a while.
Now going to attempt the 'springs' last resort.

I am about to disassemble one of my N900's for the first time ever.
I am looking for the best info on this there is.
1) Disassembling.
2) Identifying the GSM chip. (Where it is on the motherboard.)
3) Applying the 'fix'


Can you help me please?

The person applying this fix:-http://img831.imageshack.us/img831/3...1226155843.jpg

that is too much , my opinion , i have heated only one chip, that spring solution looks like a hack and slash fix

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Last night my third N900 succumbed to this error, so I finally got around to cutting up some old springs I had lying around and trying to do this springs treatment on all of them.

Initially I had good results on N900s 1 and 3, had to re-do N900 2 before it started working. Later today (about 18 hours after doing so), N900 2 against displayed the 'all telephony disabled blah blah' error. And N900 3 is intermittently losing connection to cell network and showing the no-sim-card icon, then having it reappear and getting connection back (I'm also unsure if N900 2 is able to connect to 3G/3.5G or if N900 3 is able to connect to 2G/2.5G).

N900 1 has a different unrelated instability, and currently sits in virtually un-altered, rarely-used, stock-just-reflashed state. I don't regularly carry it with me. Currently N900 2 rides in one of my pockets. N900 3 is my actual phone, and is currently carried in a cellphone holster on the hip.

I routinely parkour when moving around places (my username actually is partially a reference to parkour) on foot, so the devices probably bounce around a bit more than they would for more 'average' people, I guess. I also do a thing where if I have to text behind the wheel, I have the phone placed against the wheel of the car (that way my hands are still on the wheel, thumbs on N900 keyboard, and since I can touch-type on the N900 eyes can stay focused on the road; about as safe as texting while driving can be, I think). The vibration from the wheel might also contribute to damaging the telephony chips' attachments to the motherboard. All three of my N900s developed these issues after about 1-1.5 year(s) of use, so I suspect the above use patterns do contribute to this problem in a fairly consistent though gradual way.

Anyway, I just wanted to make this post to report my luck with the method. If nothing else, it works are triage, it seems. With more force on the chips N900 3 may even go back to being as reliable as it was before the issue, for all I know. I would love it if this works for me indefinitely. Perhaps, if I end up getting yet another N900 (if I am unable to reliably use either of my N900s as a phone until the Neo900 becomes a thing I can get), I will insert springs in as a preventative measure, which may help avoid the issue developing in my case in the first place. Worth investigating, methinks.

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

So the day after I posted this, I went and put in even more springs into N900 #3, and it has been working completely as normal since then. No random SIM card losses or disconnects in areas of known good signal.

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

I am happy to announce that I also fixed one of N900s with this problem. After testing it, I will fix the second one as they both failed almost simultaneously:

http://imgur.com/a/S3txs

The disassembly was easy if you are a bit experienced, although removing the chip cover was tricky.

EDIT: Has anyone had success with baking the PCB in an oven?

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

I wanted to log further developments with my three N900s and this issue. The case study of N900 #2 is, I think, most useful/informative.

#2 continued to have the issue after I last mentioned it, but something had clearly gone very wrong internally - instead of just having the telephony-disabled error, it began to noticeably overheat and (seemingly) drain battery very quickly. I did not have time to fix it so I eventually left it turned off until I did. Two days ago I finally opened it up: turns out, the springs I put in put too much pressure on the EM shield. The EM shield got partially popped off inside there on one edge. Using my limited physics and electronics knowledge, I conjecture that the exposed chips were getting bathed in the EM emissions from one or more of the antennas, which in turn excited the electrons in the circuitry inside, which in turn generated heat galore. It's also possible the process caused some sort of feedback loop - the electric current generated in the chips causing connected hardware to recieve signals that mapped to instructions to do something, like maybe broadcast more **** out of the antenna(s). Another possibility, one of the springs somehow managed to slip into a position where it closed a circuit between spots that weren't meant to be connected, and the heat came from the resultant 'undefined behavior'. Frak knows.

Moral of the story: clearly, there is some 'runtime' risk to these fixes, if you mess them up. After having corrected the problem yesterday N900 #2 seemed able to use telephony again, but (given my very limited knowledge) it's perfectly conceivable that permanent damage to the circuitry thus affected could have occurred.

#3 held (after the addition of extra springs) for about two weeks. It then returned to having the telephony problems. I stuck a piece of paper at the top of the simcard (inside the sim holder itself). Worked for another one day or so. I stuck some more paper (two layers) on top of the sim card slot, held in placed by the battery. Worked for another one-or-two-or-so days. Replaced the outer paper with a folded piece of thick paper (torn off the outer packaging of a bubble gum pack). Worked another day or so. I tripped the layers of the thick paper - the back cover bulged even. But it worked again. Reduced the layers to just twice the first amount instead of thrice within a day, to get rid of the bulge on back cover. Has been working for a couple of days now without issue.

I document this so that people know - sometimes you need more springs, sometimes you need more paper, sometimes you need both, and gradually more and more of it. I also want there to be a proper chain of documentation on these 'hackish' fixes to this issue. I suspect many people fix their N900s this way, post a confirmation, then it breaks again later and they don't bother to inform the community of that part. So far, my assessment remains: these fixes are good for triage, but a routinely used N900 may fail again given enough time with just these fixes. Or it may not, if you're lucky, but currently there's insufficient evidence to determine with any real certainty one way or another.

I REALLY want this stuff to hold my N900s over until I can get a Neo900. But I also hate false hope (or lack thereof), thus incessantly logging the repeated failures and re-fixes here.

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Almost same here :(

Last few days my browser began to stutter if I had opened some more windows and sometimes it felt like battery drains very fast/getting warm without any usage/visible programs running.

Tonight I was online, never saw that before, at one time my N900 completely rebooted without any press on powerbutton etc., and after that restart my telephone-function does not work anymore - it does not find my provider anymore!

Whatever I to, connect to provider isn´t possible anymore, already removed battery and restarted again, without change. If I want to select provider manually, it shows my provider, but I am not able to connect to (normal 2G)!

Is it a virus probably? Do I need to reflash anything or is there any way to find out what is going on inside my software?

What can I do now?

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

the best way is reflashing...

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

I've had this problem on and off for about a year or so.

Until now I've 'fixed' it by reflashing, but I really didn't feel like going through the bother this time (and it's pretty obvious by now that it's not a software issue).

Instead, I cut a piece of a wide elastic band to roughly the same length as the sim card and put in between the sim and the battery. I figured the elastic would be less likely to shift when the phone gets jostled than paper would.

Seems to be working nicely so far. I'll be sure to report back if/when this fix stops working.

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

It hit me too (after three years of absolute perfection) :(
But I was able to solve it with some layers of paper between SIM and battery. AND some more layers between battery and cover.

Without the latter it did not work reliably. With paper towel between batt and cover it is stable since a few days.
We will see ...

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Really crazy...a paper-strip between battery and SIM doesn´t change anything here - I also couldn´t imagine that my prob is Simcard-contact-related cause it was not falling down or anything as it happened and never had contact-probs before. Furthermore there is no sim-failure-message or something like that.

Ive done a backup-reflash (root+optfs) minutes ago through boot-menu without change, telephony is dead/no connection to my provider! Crazy, now I am going to try a complete reflash....hope it does help.


Edit: ha, phone works again - don´t now why, when I remember right my backup was made with setting 2G - now I had a look into options and saw my phone was set on 3G - what I have tried last night after failure/I wasn´t able to connect to provider anymore.

Whatever it was, now I see my provider back again after I set back to 2G, it works. But I still want to do a complete reflash cause backup was made not long time ago and the risk that there is something ´mysterious´ program on is too high for me. But thanks anyway, keep up your good work here!

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Alright, my 3rd N900 redeveloped this issue on me finally again. I did a roll (think parkour roll after a landing), and my entire weight went over the case it was in. Killed the telephony that was by then holding up fine with all of the kluge fixes here mentioned. Though I guess I never tried to also put paper between battery and cover. I may try that but I'm not hopeful. So now my life is basically over... as soon as I can I am dropping money on the Neo900 and waiting for that. meanwhile I'm using an N9 as my phone. This is my first post with it. I find it okay but nothing like an N900.Course, I already knew that it wasn't comparable.Still, best thing I got for now, and I'm done buying more N900s. three is enough I think. might as well wait it out for the Neo900.

noteworthy is that the third N900 experienced that same overheating as my second, after my attempt to fix it again. I don't think the em shield was lifted up this time, so maybe the springs are somehow otherwise causing it. *shrug*

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

@Mentalist
Thaf is really a pity and you have my full compassion.
Your alternate is a nice toy for me (see ubiboot),
but cannot really replace the N900!

And guess what:
it HIT me too a few days ago. :(:(:(
On boot:
'Could not establish network connection. Contact service.'
That's it. No cellular function anymore. :(
--and I do not parcours, but kept it like my beloved and treated it like a raw egg (usb is still fine after more than 3 years daily usage)--

Grabbed my replacement out of the wardrobe, flashed, installed backupmenu, copied everything, ran recovery, let mutiboot flash the right kernel on first boot and I am up again with my No. 1.
The other got a reflash (eMMC clashed at 32768kB, but cleaned/partitioned) and installed CSSU thumb. Installed also AIFS with cellular modem disabled to get rid of that boot-blocking message.
Waiting to be used as tablet, mail/browsing station at home (wife/kids)...

--
Waiting also for Neo900!
joerg,dos1,nicolaus and all other involved, please hurry up. Our N900 are starving...

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Indeed. It's better than the feature phone I've been using as my alternative, in between the various N900 deaths, but it lacks in the biggest area that matters to me so much - being able to comfortably touch type. I've written entire paragraphs on the N900 while driving without ever taking my hands off the wheel or my eyes off the road, because I'm so used to thumb-typing on that keyboard, and the ability to change the xkb symbol map made the shortage of keys a non-issue once I figured out how to do the remapping in the first year of owning one. Having to switch to a touchscreen-only device reminds me just how dangerous 'normal' texting while driving is because it demands so much more of your attention. Swype makes it a little less agonizing, but only a little. And no arrow keys, or page up/down, home, or end keys (which on the N900 I had thanks to aforementioned keyboard remap)... It's funny, xkb remapping was such a barely-power-user thing I got into before I ever programmed, but when it comes to daily usage, that's the biggest wall I hit in every other phone/tablet I've fiddled with. There's other niggling deficiencies of course, but a lot of them could be accepted with time, just as the N900's niggling deficiencies are accepted, and none of them dig so deeply into everything you do on the device. But that keyboard freedom/power, it feels like having your wings clipped when it's gone.

I feel your pain sir, I do.

Small nitpick: parkour and parcours are actually two different things, although the former term comes from warping the latter. Parcours is a formal competitive sport, parkour is more generally the art of efficient movement - they're closely related, though.

Anyway...

Yeah, I have to think of a use for my now-formerly-main N900. Thus far for me the N900s' fate has been that the previously main one becomes the programming device (where I do the majority of my coding and testing of apps and any on-device app building), and the one that formerly used to be the programming device becomes a blank slate for even more 'clean' testing - in case I ever needed a factory-flashed fresh device to test on, this one I could have no attachments to and the like. But now that my 3rd N900 has fallen in the line of phone-duty, I'm not sure what exactly it should be for, for now. Besides maybe my primary email/chat/IRC device, given that it's got alpine, all of my Conversations accounts, and almost all of my irssi logs on it already.

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

@Mentalist
Re parcours/parkour:
I did not know that! (so can be seen like 'freeriding' of mountainbiking?)

Re vkb:
here is your badly desired solution.
Get it from there. Or grab my attachment (incl. my vkbs), extract to /home/user/.config/meego-keyboard/layouts/, reboot and select in settings the new layout(s). Of course you may tinker with them and update in that thread...

I really hope you get your hands on a used/new N(eo)900 soon [as even above does not satisfy hw keyboarder]. But until then enjoy the N9, it is worth it.
--edit
it is worth it, but ...
... imagine why I needed to add that .txt (uploading from N9 :()

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Probably, I've not paid any attention to biking-related culture, just looking at the name, the answer is "probably".

But there is also a difference between "parkour" and "freerunning" (many practitioners would disagree, but I think there are two similar but distinct arts, one with a focus about efficiency and the other about expressive freedom, and there is overlap for many people but I think it matters that we have semantic difference to express the actual difference, in which case parkour is the former and freerunning is the latter). Off the top of my head, "freeriding" is probably more like freerunning than like parkour, since the purist definition of parkour is that it's all about efficiency of movement.

Thanks for the pointer. The funny thing is, I've been so removed from this culture we have here the last year or two that I've been almost unable to focus any time on actually researching what you can do on the N9 as opposed to the N900. I intend to fix that, but it'll probably only be once I have finished university classes that I am able to have the spare time.

Yeah, I'm just holding off on getting another N900 - decided I'll ride life out for a little while without one as a phone. Though depending on the Neo900 time-table I may very well just cave again. I've been able to manage so far, but I am already starting to feel the pain of not being able to check my emails using alpine or jump on IRC using irssi over mobile internet. (I suspect there's probably ports of both to the N9, but I also suspect it also just wouldn't be an equivalent/better experience.)

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

i've had my N900 for 5 years now and only had this problem 5 days ago when i changed telco and the new simcard they gave me.

i used 2 layers of sticky tape on the back of my simcard, reinsert it to its cozy home and voila! my precious N900 lives again!

woohooo!!

thank god i dont have to resort to taking it apart or solder it or hammer it!

i am glad.

Re: all telephony functions ... are disabled due to a communication error - anyone else experiencing this?
 

Today I applied the, I think, more permanent fix to my n900 telephony problems. But, after reading the whole post I'm still not sure how this will help? Is it due the fact of low pressure on the glued points? We will see :)
