there were a lot of posts (including one of mine) where people complained that when data network mode was activated and they tried to answer / make a call, they couldn't. and if they did try to, it wouldn't answer and the network bars would become grey (that is, no bars) and it would take a couple of minutes for network to come back (or until you restart, whichever comes first).
anyway, i had some issues with my phone and i gave to the service center. i told them of it and they flashed the stock ROM + kernel. i had some other issues as well, so they said they'll keep the phone for two days.
so i'm getting my phone back tomorrow. now i want to know if flashing the stock firmware did in fact solve anyone's issues. if it did, i'll continue with the stock rom / kernel (please tell me which was causing you the problems). if not, i'll flash a custom ROM / kernel again. please let me know.
also, does anyone know why this happens? is some app causing these problems? because after flashing a new custom ROM (without any user apps installed) i can call / receive properly without deactivating the data network mode.
but, no user apps (and no google account sync either) = no internet traffic.
i'd request the expert devs (ROM makers, kernel developers, testers etc) to please leave their opinion as i'm not the only one who faces this issue. a few of us do and this is one of the few unsolved issues on this forum.
thank you.

ur last custom rom??? wer u using 3g turbocharger??
frankly i don't know what 3g turbocharger is :/
i was using kyrillos' ROM 8.0 (updated to 8.1) and i did run the supercharger script, but i don't think that's what you're talking about. i wasn't using the 3g network.
i've been facing this issue for a LONG time now. i've changed a few ROMs but same effect in all of them. maybe it's something to do with the european firmware (i live in mumbai, india) or something, i'm not sure. are you on vodafone? where in india do you stay?
Well even i am facing this strange network problem but only indoors!!
Outdoors the range is full!!
Since we all flash custom roms that are based on european base, i thought that the problem is related to the modem.bin AKA baseband!!
So i was thinking of just flashing the modem.bin again from any asian firmware.
But before doing that i flashed the old ddjg6 (eclair) rom just to see if baseband flashing is worth it.
Well the network problem was still there!! so the conclusion was that baseband/modem.bin flashing wont affect anything!!
stay happy!!
I cant remember if kyr8 had 3g turbocharger tweaks on build.prop.. But yes with 3g turbocharger on , I hav sum issues with data connection...

Btw did u get phone.apk force close while happenin this??
-tapatalked by RnB
phone.apk force closed often. but never because of the weird data connection. i think it just generally force closed.
and i have been facing this problem since kyrillos' 6.0 or 7.0. one of the two. can't remember. also, please look for my "a request for a custom lock screen?" thread in galaxy 3 general and let me know if you can help. thanks!
also, people who are facing such issues please leave your name and "symptoms" here.
yes i also face the same problem of network,no solutions found yet.but i am not sure whether this prob happens to all the network or just VODAFONE,as i am using VODAFONE only.
okay please visit this thread :
http://forum.xda-developers.com/showthread.php?t=1229423&highlight=data+network+mode&page=2
also, here's a bit of my network story if it helps anyone understand this issue :
i bought the phone when it was running Eclair. it worked fine for a few days then i started to face the issue. when i tried sliding the green answering thing to the right, it just wouldn't answer. it would go back in it's place. when people called me, it said it was unavailable. my network used to restart, and calls would randomly get cut and i couldn't call back immediately. i had to wait for 10-15 seconds before i could make / receive any call again. within this time, the calls would dial, but not connect.
so i upgraded to froyo (JP2) from the samsung gallery. my phone worked PERFECTLY for two months or so. no call drops, no nothing. then all of the above started happening again.
i tried flashing different ROMs, kernels etc but nothing helps.
and neo, i face this problem everywhere. indoors and outdoors.
okay so i'm getting my phone back tomorrow. does anyone have any tips for me? something that i should or should not do? like flash a european ROM or just the kernel or not to install a specific app or something?
i do have the same situation. it worked very good by me, till marcellusbe released his cm7 alpha4 i think. i installed it, and since then i have got that network problem, during calls f. example i lose the communication. i dont hear amything, it freezes, and turns back to menu after a few seconds. then i notice that its in the flight mode automatically. and this just happens me when i have got the data connections on. if i deactivate it i dont face any problems like that. i also noticed since i once installed cm7 alpha4 , i have got a strange battery drain. i charg the phone till its fully cjarged, after 3 hours i do not have any battery any more.. help me in that ... PLEASE
i really become frustated the whole time when this happens to me, pls find a solution!! ....

Well if flashing customs roms and kernels is not helping, you need to try only flashing the stock modem.bin!! I really dont know how to do that safely but people do it!! If you can update the OP like "Please help in flashing just modem.bin" then maybe someone makes and give you an update.zip or a tar containing just modem.bin.
If that too fails to solve your problem, then you must demand a replacement of the handset from samsung! Thats all i can say man!!
Well, the same is happening with me. Even i have vodafone and i live in pune, india. I didnt use eclair for alot of of time so I don't know whether it is a froyo-eclair prob.
The problem that happens with me is that, when i go to my classes (which are in a damn closed area) i dont get any signal. Even though the network bars are zero i still get messeages and phone calls. but when i call someone or message it does not reach. It only happens in some places like my classes and school, but not at my house.
I found a way (not quite conventional but works). I have found that when i flash a rom; irrespective of whether stock or custom; the signal catching is quite stong. But after a month or two it is becomes laggy again. So i flash another rom and again it's good. I dont know whether it is a correct method but works for me.

Same place!! Pune!! But i get the problem only in some areas!!!
okay so i've been using the stock firmware for two-three days now. and i've been facing absolutely no network problem as such.
when i press *#1234# here are my results :
PDA : i5801DDJP2
phone : i5801DDJP2
CSC : i5801DDJP2
build info : 2011, 04
now can someone interpret this for me? i mean tell me what exactly this means. which of those is my ROM build, my kernel build, or baseband or whatever.
tell me if there are any custom ROMs / kernels built on these builds (or updated ones, but still indian updates) so that i can test if those work for me?
thanks.

There is no custom rom build on this build as this build is lot buggy than the other european firmwares.
And that phone is the baseband responsible for the network and all!!
Some people face network problems some dont!!
Here is the phone of i5801ddjp3 firmware
http://www.mediafire.com/?34yrw4b7fe63tri
If you unzip this file, you get the modem.bin
Now there has to be a way to flash this modem.bin over custom firmwares!!
here is the sgs version of it!! This thread contains of all modem.bin of stock firmware to be flashed over custom rom to get better baseband for samsung galaxy s!
Even I used to face similar problem but only on custom rom's not on stock ones.. but using the stock rom's is too boring so now I have flashed with purungrit's rom v.1.0, kernel G3 mod 2.0, and its working fine, no network issues. The theme is good with extended power menu and 5 lockscreen.. u can try this. we can flash custom rom's based on Indian firmwares and face no network problems, problem is only with European or other countries firmwares..

But the problem is that indian firmwares are a bit inferior as compared to european firmwares.. If you compare any indian firmware with jpq or jpu you will feel the difference..
I really want someone to try that modem.bin method
Tapatalked from my awesome G3 aka apollo
Ask some of the devs that whether this method can be used n is it safe.. than we can go for it.

Hello I'm new here
I have sasmung galaxy s plus GTI9001 device with it's official stock samsung android rom v2.3.3 and from a while I wanted to update my device to Android Jelly Bean 4.2.2 so I tried 4 or 5 stable and good roms like Cynageonmod 10.1 and MIUI and Jelly Beer and TigerJB Rom..........etc but they all have this WiFi issue with my device although as I saw it in the comments and screenshots of these roms the Wifi works on them with no problems
the problem is that after I flashed my device with these roms and followed there installation steps correctly everything worked just right with no problems at all but when I turn on WiFi it just keep searching for wifi networks with no result I left my phone for a full hour searching for my wifi network at home but there was no result and when I returned to the official stock samsung android rom everything worked just right even the wifi but on other roms I have this WiFi problem that I told you about so can any on help me ?
I really want to have Jelly Bean running on my device but I can't make use of it without Wifi working correctly to browse the Internet with it :crying:
and I'm sorry for my bad English
When you install a ROM, is your WiFi Mac address listed under About Tablet > Status?

Under Settings (in your custom ROM), go to "About Tablet" then tap on "Status". Check to see if your Mac Address is listed and doesn't say "Unknown". If it is listed, then you need to check your router settings and make sure it is configured to allow communication with your device. If it is not listed, then there may be a problem with the ROM. It can usually be fixed, but you'll need to do some searching first. Just search XDA for "missing WiFi mac address" and you'll find tons of usable information.
I just recently brought myself a moto g LTE coming from a nexus 4 device.
I would like some help or advice anything to sort this little problem out I have.
I unlocked the bootloader flashed a few custom ROMs but what I noticed is the device is connected to the WiFi but no data is being transfered. I try using chrome or play store but I get nothing loaded. I have to reboot the phone a few times then it works and then it stops working again after a while.
I don't seem to have problem with any of my other devices I've even changed the channel on the router but I get nothing.
Using data on the phone is fine, but nothing for WiFi.
I hope somebody out there can help with this.
Thank you

If this happens in all the roms you flashed, try 1.) another router (to check if that is the problem) or 2.) flash a different radio.
If this happens on just this rom, 1.) make sure the rom is suitable for your model or 2.) ask in the designated rom thread and ALWAYS mention your model, rom and rom release version. Search XDA on how to logcat and make a proper bug report.
Good luck
Hey ppl, whenever I change my OPO in 2g only Mode, it does losses is connection totally, like no signal at all, but as soon as I change my network preferences to either 3g or LTE, I do get back my signal... I'm currently running CM12S version YNG1TAS213, rooted, bootloader unlocked... I'm having this problem since last week, as a result of too many flashing... I'm really thankful if someone could help me out... I tried multiple flashing, I called up OPO customer care, they told me to use oxygen os to have this issue sorted,but still the problem persists... Kindly do help me out ppl... (sorry for my ebullient, as is not my first language)

Suddenly the wifi in my samsung galaxy grand duos i9802 is unable to detect my home network. It keeps showing it as "out of range". It is not even able to identify any other wifi (tried to tether from another mobile but did not identify it). But surprisingly all other devices in my house are able to detect the same wifi without any issues. So obviously something is wrong with my phone and i cannot understand what. When i tried a factory reset the problem got solved temporarily so for the first time it detected the wifi but again after some time it went back to the same problem as earlier by itself. And since then again it keeps showing as out of range.
I would prefer to solve this issue without installing any custom ROM if possible. Is there someone who has faced a similar problem and could solve it without flashing any custom ROM?
Personally i am not in favour of any custom ROM because most of them have some or the other known issue like radio not working, dual sim always enabled, google maps not working or something like that, but with the stock ROM i do not see any such issue, so i would prefer if it could be solved by simply updating some driver of wifi or any other simpler solution. Would like to avoid rooting as well if it can be solved without rooting.
Can somebody help me with some knowledge here?
Hi, thank you for using XDA Assist. Better than a factory re-set, I'd try flashing the stock firmware with Odin. If there's stilla problem it could be hardware. For additional help see your device's specific forum here, http://forum.xda-developers.com/galaxy-grand-duos
