Here is the deal,
Phone worked pretty well since I bought it. I changed the ROM a couple of times and everything went fine.
But at some point, something changed and when now I switch off the wifi, the data connection doesn't work anymore. Also, as other users complain, it occurs when the phone enters in sleep mode.
Entering in Airplane Mode and exiting seems to solve the issue. Also, switching from 2G to 3G (and viceversa).
Things that might help:
I did some research and it seems strongly related to the Android 2207 Issue (you can google it, I can't post external links yet sorry)
It happens with every ROM that I try: CyanogenMod, MoDaCo and now with MIUI.
Also, it happens with BB 622 & 725 (with respective RILs). With 502 I don't remember having this problem, I would try again.
If someone else has this problem, share it with us. And if anybody knows how to solve it, it would be great
Thanks!
Hi all,
Since about 1 year i'm a happy owner of the Galaxy Note. As the stock rom was quite crappy (eating battery like crazy) I decided to swap it with a CM10.0 flavor (Cookies & Cream).
Well, installing the ROM went fine and the phone worked great, except one thing.
Since the beginning that i'm using custom roms on this phone, i'm randomly having issues with the telephone or 3G signal. As I thought, maybe the ROM is full of bugs, I wiped the phone and installed the official CM10.0 ROM. Unfortunately that solved not my problem. Since a couple weeks ago i updated to CM10.1, and still having this issue.
However, some issues where solved since the last upgrade:
- First ROM (CM10 flavor, Cookies & Cream): randomly dropping the signal, and asking for a SIM pin. Sometimes even a restart was needed
- Second ROM (Official CM10): same as above, but less issues with the SIM, mostly signal related
- Third ROM (Official CM10.1: SIM issue gone, however the phone is sill loosing the data signal + sometimes even the telephone signal (restart needed).
When I loose my signal, something it's just the data connection (3G/H). The strange thing is that most of the time that this happens the data connection or telephone signal restores when I enable/open the screen by using the side/home button. Well, that's very strange as I have no power saving apps or something like that running.
But unfortunately this is not always the solutions. Usually 1x per 2 days I have to reboot the phone in order to bring the signal for telephone + data back alive.
SIM has already been replaced, with no luck. I did install this ROM on another phone (from a friend) as well - which had in the beginning the same issues, however things seems to be become stable (haven't heard him anymore)
I already tried different modems on my phone (XXLSA / XXLSX, currently using XXLSO), but none of them solved this loosing data/telephone signal.
It starts to drive me crazy, as I use this phone for my work too.... being unreachable is quite annoying
Anyone an idea what goes wrong here, or how I can find out why this phone is going nuts?
Nobody that could explain why my phone is having this behavior?

Hi guys.
Since last week I've been having an issue. My phone ramdomly looses signal for like 10 seconds and it generates a folder named "bd-dumps" with 3 archives on it: ramdump_modem_fw.bin, ramdump_modem_sw.bin and ramdump_smem.bin.
I didn't changed anything on the phone when the problem started. I was running LiquidSmooth ROM (Very nice, BTW), and started noticing this issue. In fact, I just noticed because my phone was lacking memory.
Now, I've been searching about this issue, but none of the solutions have worked for me. Some say is a bad SIM Card, others a bad network, but I am pretty sure that the issue is not about that.
Everytime that I turn on Data services, it happens. When data services are off, it doesn't.
Anybody has have this issue or have any idea what is this about? I attached some screenshots. Thanks!
Edit: I already changed ROMS, flashed Stock with RSD and flashed modem, but the problem still the same.
This is old.
http://forum.cyanogenmod.org/topic/79890-modem-crashes-on-102-nightly-28-sept/
Been happening on CM based roms since 10.2 or before, for me it will only crash while on H+, 2G won't crash. Stock rom doesn't crash. Already tried buying a new SIM card too.
Devs are either unaware/not willing to look into it/not capable of reproducing since it only seems to happen to certain unlucky people, probably related to some types of networks, since my crashes only occur while on certain regions of my country.
On the other hand, if anyone capable enough is willing to look into this, i'd glady crash my phone a thousand times to generate logcats, dumps or whatever is needed to debug this ****, after all, this is a dealbraker for CM, this is a phone after all.

In my case, it does crash on Stock too. That's my problem. I flashed with RSD to Stock and still the same.
I have also tried other ROMs but the problem still the same. Any ideas?
Thanks
Modem still crashes for me on anything not based on stock 4.1.1 / 4.1.2 - That said, latest PAC jbbl 20140825 has had the least, but persistent and consistently crashing at the same intervals.
I came from stock 4.1.1 latest ota to 4.1.2MX then PAC jbbl 20140825, only got about 6-7% signal loss. Where as all other roms 4.2 4.3 and 4.4.x have been similar results in the 20-30% signal loss.
In your case, if you've not realized since, your modem might be bad hardware-wise. Since you say it was working and then started suddenly, even on stock. Stock I get 0% signal loss.
Im seeing multiple people saying that they have WiFi calling on Project Fi running a latest AOSP ROM like Chroma or AOSiP, but I cannot get it working. You cannot put phone into airplane mode to force test it, so how are you verifying it is going over WiFi? It is supposed to show the SSID in the call, but I cannot get it to do this, even with poor to no cell service.
EDIT:
It is not working. Either people were lying or dont understand how wifi calling works for Fi, but once asked to perform a screen shot, they changed their answers to, it doesnt work, but everything else does. Which all AOSP ROMs have before.

These ROM's don't let you put it Airplane mode so the toggle isn't there or doesn't work?
Will update 1st post.

The latest Pure Nexus ROM worked for me. I noticed there was a third file posted along with it called a "Google dialer.". Required to work with project Fi. I did a clean install (wiped everything) since I had wiped my phone clean anyway, and installed the stock ROM (after being used to Chroma).
Turning on airplane mode on my phone, then Re-enabled my WiFi connection. Made a call as usual, and it went through. On both the stock rom and Pure Nexus.
How can I know for certain that I am getting WiFi calling, other than knowing I had disabled my cellular radio? I would be more than happy to install software and take a screenshot to help. I'd been using Chroma as my goto ROM on my nexus 5, so I did the same after the small nuisances in Stock 5.1.1, like pocket dialing. I really would prefer an led notification over a whole screen one. But that's just me. I hope I helped some.
Hello guys,
For the past year or so I am having intermittent problems with my 3g connection. It just loses the connection with the mobile internet without any error messages and the only way to fix this is rebooting the phone. At first it happened every couple months but the intervals between connection losses seems to get shorter. The last few months it was every 10-14 days, now it's every 5 days. Since a reboot seems to fix this I don't think there is a physical defect on my 3g chip but the shortening intervals are somewhat worrying. I checked my APN settings multiple times and I've called my carrier's tech support several times but they too can't seem to find anything wrong with my APN settings. I'm currently using a custom ROM (OmniROM based on Android 4.4.4 with the Stagefright patch included) but this problem existed even in the original ROM so I doubt it's a kernel/driver issue. Is there anyone knowledgeable enough to pinpoint the problem or at least help me in the right direction because it's becoming a bit annoying and I dislike not being able to figure out WHY something happens. ^^"
The issue you have mentioned applied also to my phone, but it appeared for the first time after installing Omni from golden-guy. I haven't observed it on my stock rom. At the very beginning, I was able to mitigate the issue by turning airplane mode on and off. As you mentioned, the issue's frequency was increasing over time, leading to more than one signal lost per day. Airplane mode solution stopped working. I have also tried to kill (and got restarted) rild, as well as radiod - with no luck. Logs (I haven't checked kmesg) revealed nothing. I'm not sure the details of your issue, but I was loosing the whole GSM/WCDMA signal, not only the Internet access. Meanwhile, the system seemd to be looking for a network, draining my battery.
I still hope that the solution was to replace my SIM card with a new one from the operator. After that, about a month ago, the issue happened only once, and airplane mode on and off solved it. It's worth to notice, that turning airplane mode on took quite long time, about 30 seconds.
I'm having GT-I8190, Omni version 4.4.4-20151108, baseband I8190XXAMG (I'm not sure if it is distributed along with the rom, or maybe resides on different partition, and is not updated with the omni rom releases).

Did you check logcat? If you didn't then logcat might show what the problem is. And your problem sounds more severe than mine. I only lose 3g but I can still call and send text messages. A problem with the simcard might be possible but it could also be a physical problem with the simcard slot though I can't say why rebooting or turning airplane mode off and back on would fix that.

I just wanted to confirm that I have similllar issue with 3g data connection. S3 mini with I8190XXAMG4 baseband. Stock ROM used for last few years (without any significant issues with 3g data connections), upgraded to latest CM11 20151017 from maclaw/novafusion. I noticed that there are some glitches with 3g data connections. Sometimes I need to tap few times before connection finally is being established. Funny thing is that I have second s3 mini with the same CM11 20151017 and all is OK.
I tried a lot of another ROMs; fifferent version of CM11, OmniROM (4.4.4 and 5.1.1), CM12.1 - problem remains - issues with 3g data connection. Is there any solution to get rid of this 3g data issue?

Yes, logcat (main, radio, events) revealed nothing but just signal drop to 0%. At that time, I didn't know about kmsg and system logcat buffer, so I haven't checked them.

Just tried this, and it helped. Usually, when something is not working, people try to turn it off and on again.
I always had rare glitches with mobile data connectivity, and turning mobile data off and on again always solved the problem. I think our problems my be hardware related. I suppose my old SIM card could have buggy software, i.e. advertising to support some newer protocol, but actually didn't. After upgrading, the phone tried to use the new advertised protocol, and got confused, or made the SIM confused.
I also know about cases, when SIM card simply died without any reason.
I used Note 2 about two years, flashed different roms and never had troubles, but then my friend used it about 3 months on 5.0.2 custom and got troubles with gsm/wcdma. My next samsung phone become our beloved i8190. Flashed it from stock to 5.0.2 CM, than 5.1.1, after month got first Cellular bugs. Tried another LP and some KK roms, my troubles with baseband became more and more frequently every day, flashed different modems, changed much settings in system.. So I was desided that it's all HW problems, and hated Samsung for such failure. But one day just tried to install Project Noble, and all this troubles gone forever. So it's just drivers, which not optimised for new Android versions. 4.1.2 mixed with old TouchWiz after fresh and clean Lollypop feels horrible, but we can do nothing with it.

But if it's hardware related, wouldn't you think that rebooting our phone or turning airplane mode on and off wouldn't fix it? And did you see in the logcat log if something happened before the signal drop? Sometimes events prior to the signal drop can also tell something about the cause.

Hardware could also have its state, which may get corrupted and reset on reboot.
