Tethering?

Why does my phone think it's being tethered? My Arc S is rooted on .42 Gingerbread firmware, stock UK ROM, deleted a few files/apps, and those are about the only changes I've made.
But recently when I use the 3G on my phone (not wireless, but data) after a while it diverts to my service carrier's page about tethering and how it is not allowed on my plan (which is true).
I phoned up my carrier thinking it must be a problem on their end, the guy told me it to try my simcard in another phone and see if the same thing happens- It didn't, I was able to browse with no problems at all. Put the sim back into my Arc S, and after about 30 seconds of browsing I get diverted again. He told me it may be a problem with my phone and I should factory reset.
Obviously I don't want to do that as I will lose root plus ROM plus all my customisation (Supercharger, Go Launcher etc) so what could be causing the problem? I've been using it fine for a long time and then this happens....

If it was a problem with the firmware wouldnt the problem have appeared straight away, rather than after a few weeks?

[Q] Lost Data Service Overnight (i317, Xylon Rom)

I've been running Xylon Rom for some time without any data/internet issues. This morning I unplug my phone and there is no data service. I can make/receive calls and texts but have no data/internet service.
I spoke with AT&T about my issue but they were unable to resolve it and recommended I get a new sim card.
Any recommendations would be appreciated.
Thanks

Did you check your APN? Maybe try rebooting the phone. It shouldn't just disappear for no reason.

YEP! Thank you! I wonder what caused it to switch like that on its own. Again, thank you!

Glad you got it working
Sent from my SAMSUNG-SGH-I317 using xda app-developers app

Just a trick for future issues...
Go into your APN settings and create a duplicate APN of the one you use in a new location. Then dump the APN's you don't use.
Xylon is clearly a CM variant build, and contains 3-4 extra APN's already yes ?
Dump the ones you don't use, and leave the one you do, then create the duplicate.
That way, the system only has the correct APN to use, and will still function if it reverts to the alternate APN......g

3g/4g Network

Hi, my dad brought the this phone from China (for the second time, the first phone got bricked) and it came rooted with an ics rom. Wifi and the edge network was working,but I could not get 3g or 4g data. (It showed a 'G' on top of my network data bar on the top right). Is there a rom i can download that will allow at least my 3g data to be working. So far I tried cm10 but only the edge network worked and I had no wifi connection. My Baseband is SU640-MDM9200B V10i. I live in Canada and the phone is from China. Who knows what is wrong?

As far as I know the radios are different so that could be the problem.
Sent from my LG-P930 using xda app-developers app

you have to modify build.prop to correct region so your phone uses the proper radio settings for this region.
i'm not an expert but you can get a build.prop editor on play store, change the region to US i think it's ro.product.locale.region is the entry i think that's what it is on my rom atleast

Thanks for the suggestion, i tried your idea but no luck. I changed the value of that line to US and also CA but it was still giving me edge network.

Lol yeah I did this already. I put the correct APN (the same one I use for my lg optimus 2x that receives data connection). Thanks for the suggestion though, it's the simple ones that are usually the solution. Not this time though

Same problem happen to me when I changed the baseband before set the network mode to "GSM/WCDMA preferred".What I do is to rollback "the initial baseband" and make sure is 3G available.

What is your baseband now?Have you ever changed it?If yes, rollback your baseband using " dd if=/sdcard/baseband.img of=/dev/block/mmcblk0p14"(baseband.img is the one you used before,v10i,v10f...or else) ,after finish reboot your phone and set your network mod to "GSM/WCDMA preferred". (not sure it will work,just for your reference)

Haven't done anything to the baseband. It is APQ806/MDM9200. Should I just type that line into a terminal I download from Google play.
Extra info: I'm rooted on the newest jb v30c but can't seem to get into recovery I think because it's a secured/locked boot loader.

Check "network mode"，is it "GSM only" and unchangeable？Otherwise this probably not a baseband problem

Before and after I input the code the network mode says 2 things... Lte preferred and 3g only. Either one I choose gives me the 'E' network above the bars.
Just out of curiosity which country and carrier are you with?

[Q] I messed up with Titanium Backup and now it says 4g, but data doesn't work

So I had to get a replacement Note 2 from T-mobile because my first one had messed up sensors or something. When I got the new one I wanted to backup and restore all my apps from the original.I used Odin to flash CF auto root and do a app and system backup. Then I rooted to the new one the same way and did a restore. I apparently didn't read enough about Titanium backup and restored everything including the system stuff.*Now my data doesn't work most of the time. Specifically when my phone says 4g, no matter how many bars, nothing has network access. I can make and receive calls and text messages although calls have been very spotty with reception. However if I have 4g LTE signal then everything works great. Can anyone suggest a fix? I flashed the stock rom again and reset APN settings to default, nothing is different. Side note, I was able to reset flash, unroot and return the old phone to T-mobile. Any help is greatly appreciated

Have you tried a factory reset?

I did do a factory reset after flashing the stock ROM. Both through the settings menu and by booting into recovery. No change.

Am I really the only one that has had this problem with titanium backup? I read a lot before rooting, but apparently not quite enough. Please, if anyone has any ideas or has had this problem, a little help would be greatly appreciated. I would hate to have to send back another phone espevially one that is otherwise perfect. Everything is great when im on wifi or LTE, but 4g gets me nothing. Thanks

I don't think that this video is related to my problem. I can make and receive calls and texts with 4g or lte. However I have no mobile data connection whenever I am connected with 4g. All apps report no connection. When I have lte signal all apps work with no problem. Also my imei number is not gone, it is in there correctly.

Just an idea here. ...
Do you have an Add Block app of any kind? If you do, try to turn it off and see if that is the problem.
I had one that blocked my data, but only on Wi Fi. It took me several days until I found the problem.
Good luck.
Hit my "THANKS" button! Come on, you can do it!

i had similar problem
my settings were set to LTE only in factory menu.
so i would get internet only if LTE signal was available.

Have never had an adblock app of any kind. I know for sure that the problem was caused by me restoring all system apps from titanium backup.

Have you tried flashing the radio?
You would have to flash a custom recovery (recommend TWRP)
I also had that problem on my Nexus 5 for a few days, I upgraded my ROM but forgot to flash the Radio again, and after flashing radio in custom recovery all was fixed, was strange because SuperSU carried over and it was just a delta (65mb) update, must of screwed the radio I guess. All is working now though.

#cjp420 did u find solution, i have same problem

I did not, but I never tried flashing the radio like the previous commenter said. That actually was an idea I had, but didn't try because I asked and people were adamant that I shouldn't do that.
Believe it or not I am still using the same phone still with the same problem. It's not a big deal because I set it to only connect to lte or gsm so it never connects to the regular 4g. Everywhere in and around austin that I tend to go has good lte reception so I don't really miss it. The only part the kind of sucks is that ot switches to E whenever make or receive a call because there is no voice over lte apparently.

Galaxy nexus network issue! strange behaviour

I got a nexus from ebay the seller was from HK, i recieved the phone and everything works except for calls/texts. The phone just doesnt get the signal on the notification bar it always has a small x showing no service. Few strange things happened when i tried experimenting. I checked out all the forums and all possible solutions with no help.
When i insert a sim card and enter a APN there is still no network but i get internet from the sim card( i am sure im not connected to wifi). I get my whatsapp msgs but as i get my msgs the signal bar still shows there is no coverage.
Also when i put phone on airplane mode, in the lockscreen it says my networks name(airtel) and when i check my status it shows that there is some signal strength but im unable to make calls or texts or use stable internet.
I tried changing the baseband, tried all the global basebands with no luck.i flashed to 4.0.4 from googles official site too.
When i search for networks manually it shows my network along with a bunch of others but when i try connecting it fails.
Im attaching few screenshots of what i explained above, please help me out.
Thanks you.

I am also having the same issue all of a sudden. For me only Vodafone sim is not working here in mumbai. Airtel is working in my gnex. So the only option for me is to port my number to airtel. You can also try using sim cards of different network provider. Also try to use cwm recovery 6.0.3.5. Because the latest cwm recovery also causes some problem with the network( thats what i read in some forum).
If you get any solution kindly share with us.

Try other sim cards of different network providers and check which one works for you. If you find a working one the only option you will have will be to port your number to that provider or buy a new Sim. I am also planning to do the same
