App Blocking 3g Access

I currently have something on the phone not allowing 3g access. I can't seem to figure out what it is, but I believe I narrowed it down to an App. I did a wipe and clean rom install and 3g was working fine. I did a titanium backup restore of all apps with data and now 3g isn't working again. Anyone know of an easy way to pinpoint what is blocking my 3g? I tried ending all tasks in advanced task manager, but I'm guessing the phone would need a reboot to bring back 3g?

Have you check you settings-wireless & networks-mobile networks-use only 2g networks?

ya I tried using only 2g network, I even tried researching the network and it finds tmobile in the settings. I even went as far as getting a fresh sim card prior to wiping the phone. Somehow after an app/data restore from titanium back up, tmobile internet no longer works still. It's why I wiped in the first place.

1) Double check your APN settings in settings > networks > mobile networks
2) In dialer, dial *#*#4636#*#* > choose phone info > scroll down > verify that 'set preferred network type' reads WCDMA preferred.
3) Also in settings, make sure you didnt set 'use 2g only'. Same location as #2 above

Thanks for your help. I actually just did a nandrestore from an image I had that was a week old and internet came back, so it has to of been something I done within a weeks time. I just hope I don't end up hitting the app that stopped it, if I think it was one, because thats the only thing that makes sense to me.

I have your same problem could you be so kind as to attach the img you put so I try too? thanks

Then you will have his phone.

you mean....?

i Think i have a similar problem... I turn 3g on and after half an hour i cannot access the internet anymore... The sign in the notification area shows the "sent arrow" blinking but the receive arrow does nothing... I have apndroid to control my 3g usage... I unistalled it, did a reboot but again the problem persists... Do you have anything in mind???
I forgot to mention that the exact same thing happens with 2g network as well

When someone does a nandroid backup, it backs up all the data on the phone. All of it, if you restore it to your phone, you will be logged into google as him, you will have all his contacts, messages, settings etc. If one of you downloads something, it may download on both machines. The only way to fix it would be to wipe both of them.

i have the same problem. two days ago its working fine. i just turn on turn off the wifi and it just works again.

Can also try turning the airplane mode on/off. This problem occurs if you use APNdroid or similar, or toggle mobile connection on the Desire ROM.

tired of trying and try to wipe, reset, several rom, so I decided to send it to HTC in England ... and the problem is which has the bootloader unlock my ...

Loose 3g data when Wifi is enabled with CM6.RC1

There have been a few discussions about this, but I have yet to find a solution that works for me...
I flashed CM6 today and now I'm finding that when I enable wifi, my 3g data connection is lost. Not sure this is really a CM problem, I just want to find a fix.
My setup:
Nexus One - CM6.RC1 - FRF91

what do you mean it's lost.. when you're turning Wifi on, that's the whole point (that you want to use your Wifi connection for data, and not your mobile 3G data.) Maybe I'm not understanding you?

Even with wifi on you still need 3g data to send and receive MMS. I can't replicate this problem, though, so I'm afraid I'm not much help. All I can suggest is trying a full wipe of everything but battery and rotate stats and try to flash it again. See if that helps.

It works fine for me. Are you sure you are confussing not having both icons in the notification bar with 3g being off?
I answered this question a few months ago too.

Your 3g is not lost, it just hides the icon. Go into settings and look what network you are still connected to for yourself, it will still say 3g. If you were to send or receive an mms the 3g icon would briefly pop up, send the message, then disappear. Your phone is working just fine

thanks for the help... @roger, you are correct, i didn't realize that the icon was hidden vs. actually turned off, nor did i think to go check the actual service rather than rely on the icon

i9001 (S plus) won't save APN settings for 3G

I tried enabling mobile data in my Samsung Galaxy S plus, but no 3g indicator poped up. So i checked the apn settings and I see that no settings are there at all.
I tried making a new apn settings or even make my provider send me the apn settings themselves, but the settings won't be saved (the list remains empty!)
Any solutions for that?

That's what i'm saying mate. Although i hit save, the list remains empty...

Hi.
Same situation happened to me on my Samsung Captivate (googling solutions led me to this post!).
I think I was able to get my 3g issues to fix after I toggled airplane mode on and off. After doing that, the 3g label showed up on the menu bar, and I had 3 options available to me in the APN settings. Also, the Data Usage tab began to show stats for Data, and not just wifi.

TRy deleting or replacing the "apns-conf.xml" file found in System/etc.

wow... this solved the issue. After I deactivated Airplane mode, the settings came back. Many thanks m8! (really weird that it did tbh, but meh )

I would do that also just to be sure, but i haven't rooted the phone yet and I hope I don't have to (although I will sooner or later )

I would not know why it is like that, maybe someone more technologically-savvy could figure that out. haha
Just make sure to toggle airplane mode everytime you reboot your phone, because this "fix" is not permanent

will have that in mind fermata_. Thanks again

[Q] CM10 and no connection to internet

Hello all,
I flashed CM10.0 a few weeks ago and everything was working fine up until 2 days ago, now my I9000 won't connect to the internet at all. I was using Easy Battery Saver which cancels the data signal everytime the phone is idle, but this stopped turning the connection on. I uninstalled it hoping the phone would revert back to normal but can't get connected. I restored the app hoping it would pick up the settings again but still no joy.
I have wiped everything including user data and the caches, done a factory reset and reflashed the rom. The signal did return for about 30 minutes after the flash but the connection has since died again. I've tried switching on the roaming and national roaming, also no luck.
Does anyone have any idea what might be causing this or even how to fix it?
Thanks in advance

I am just guessing, but as from what I understand you uninstalled the application when you were not having the internet connection working. Right? The correct settings have possibly remained overwritten (some applications block the outgoing data traffic by changing the connection settings). Give APNDroid a try and if unsuccessful try going to your phone operator webpages and find the correct connection settings.
I am using CM10 with APNDroid which works fine. However sometimes I cannot connect to 3G as well. Switching the APNDroid on/off couple of times or rebooting solves the issue.

Thanks for the response mate. You guessed right, APNDroid hasn't fixed it and I haven't been able to find APN settings other than the one that is already in my phone. Might reverting to stock solve the issue? My contract is up at the end of the month so I could handle living with GB until then .

Hi again, reverting back will definitely not solve the issue. From what you had said I understand that the internet settings are somewhat messed up.
These settings are bound to your SIM card. By up/downgrading ROM these remain.
Could you check if your APN settings are correct (I assume you need to check with your provider).
Good luck and keep us informed.

Just found the APN settings online. Reset my APN and it looks to be working. I'll keep an eye on it just in case but I think either the ROM or the App messed up the user/password on the APN.
Hopefully it's all fixed. Thanks for all the help.

first try apn tweaker from market then if no luck what worked for me

[Q] Droid 4 + JB = Phone or Data - pick one?

I have a Droid 4 with stock 4.0.4 that works perfectly with Polish Orange operator (GSM). I tried to install some JB rom, but when I go to 4.1 or 4.2 I don't have any data connection. At first I thought it was a problem in some particular ROM, so I tried almost all 4.1/4.2 builds I could find on the internet. They all have different options, more or less, but I didn't get data connection on any of them.
The second try was to modify 'something' in build.prop. I had no idea how to start so I checked some tutorials and xda topics and I looked at any options that could be related to data connection. After many tries I started to think that it's just impossible, but then I got the setup with working data , unfortunately the phone application started to hang or FC on all phone connections.
The next thing I could do was to narrow it down. I tried some combinations of build.prop, apns-conf, restarts and wiping and I've found a single setting that changes everything - "telephony.lteOnCdmaDevice". It seems to work this way:
1. Just after the installation of any ROM the option is set to 1. You can make and receive calls and SMS's. Wifi, GPS, etc. works. But regardless of what network options I use, if it's LTE or just 2G GSM, what APNs I set, if I reboot or use airplane mode - there are no data at all.
2. When I change this setting to 0 and reboot I immediatelly get the data connection. I don't even need to set-up APN (In fact it works even with VZW default APN, and I'm on Orange PL). It works on 2G and 3G, on GSM and LTE, I get all networks from Edge to HSDPA. So the phone is able to get data connection. But when I try to make a call the phone app hangs, and when I receive one it FCs.
For both of those cases I tried many different configuration options, with reboots, wipes and so on, to make sure that connection depends on build.prop setting and not on anything else.
So at this point I know that the phone is able to do both connection types, but how to get them at the same time?
BTW: I know about using Google, forum search and so on, I tried to find any clue about resolving this on my own but now I'm just stuck. However I've found something that I didn't find anywhere else, so maybe with your help we'll find some solution .

Ok LTE only works with verizon and apn depends on your network
I'am use a mod I flash thet after rom install and this mod patch the build.prob an add a larg apn list
So only flash the mod an have fun

Thanks for saving my phone @NighPlayer32 . I still got some random shutdown so I need to test it more, before I use it as daily device, but now I see light in this tunnel. The phone and data works, even without any touch in settings.
I'm going to check this mod in more details and understand what it does, so I may get back with some more questions .

Thanks
