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 ...

Lost my data connection. No Icon or anything. Help!

No longer have any data connection. 3G/E/H etc is gone. No icon at all.
I've tried a couple things:
I tried airplane mode on/off.
I tried the *#*#4846 thing and disabled radio there. I changed the network band. I tried "Enable data connection" there and nothing happened. I made sure it was enabled on boot.
I removed my sim card and put it back in. Started phone with/without it.
Wiped the phone in recovery. Reflashed Cyanogen/gapps.
Reflashed the radio.
Tried Modacos senseui just to give it a shot. Still nada.
NOTHING is working! Anyone got any ideas or any other fixes I can try?
This is really killing me...

ok i had this problem last week and this is what i did and it worked for me.
1.Settings
2.Wireless and Networks
3.Mobile Networks
4.Access Point Names
5.Make sure it says epc.tmobile.com
if it doesnt say that then just add it and when u finish just hit save and wait a couple of minutes and there should be a E/H/G Hope that helped.

sounds like a carrier issue..i have had this happen with tmobile in the past .. just typical network gremlins..

[Q] 3g will no longer connect

I installed CM6 onto my sister's Hero as well as my mom's Hero. My Mom's Hero works fine but my sister's will not connect to the 3g network! I have gone through and turned on/off all of the network settings and can't get it to re-enable the data services. Wifi works, calls/text work, just not the internet connection over the mobile network. I tried flashing Fresh to see if that would work and I get "Data Call Failure - Error Code 67 .Registration failure. Your PCS Vision username and/or password may be incorrect. Please try again." repeatedly. The 'Mobile Network' in the settings menu in Fresh stays stuck on "Turning on...". I don't get that error in CM6, however. I've tried reflashing/wiping as well with no luck. Is the 3g radio separate from the radio that does calls/texts? Is there a way to check it? I don't want to tell her that I broke her internet connection :/

What radio are u using on that phone? And what all have u wiped?
Root-Hack-Mod-Always™

I was using the most recent radio I believe, 2.42.01.04.27, and I tried wiped everything in recovery. I continued searching for an answer and was able to find a thread that solved my problem! http://androidforums.com/sprint-her.../13197-data-call-failure-error-code-67-a.html
I just had to go into system updates in about phone and perform a 'profile update'
When I first setup her phone she couldn't remember her gmail password so we reset it and she was able to log in. I completely forgot but her 3g worked for that day! the NEXT day we noticed it wasn't working and it stayed like that for a few days until I was able to fix it now. She set up her gmail account at the sprint store when she first got her phone, could her gmail password somehow be related to her PCS username/password so that changing it screwed up her ability to login into the sprint PCS service? I'm still confused as to why this happened on her's but not on my Mom's phone, and never on my phone!

I had this happen saturday night,, running dd 2.8.. data would not start for nothing.. I nandroided back.. and all is good!!

[Q] Wifi disconnects data network after gingerbread update (i9000m)

Used Odin to update to gingerbread from froyo on my i9000m the other day. Theres no service here at home unless I put the phone on the bathroom windowsill, so I didn't notice until today when I went to work that I wasn't getting any data network connection. Could make and receive calls fine, wifi works, but no data, so no browsing or facebook or any apps that require it. I called bell and they came to the conclusion that I have to send the phone in for repairs. Thats a absolute last resort, so I tried another factory reset, this time from the recovery menu. The first time, during set up I enabled wifi, this time on a hunch I did not, and it worked. Also note that the first time, the network connected for a split second before disconnecting again. Anyways, I was getting 3g fine, then I tried wifi, and it disconnected again. Turn off wifi, data comes back. Whats up with this?

Did you set your APN? Go
Settings > Wireless and Network > Mobile Network > APN Names
Then hit menu and add a new APN if none are there. If one is there, it's named something like 'browser' (at least that's what mine is called on my Bell i9000m) and I'm wrong. But I had this problem, and this is how I solved it. You can find the APN settings for your network by google-ing "[Provider] APN Settings]", and if you're on bell you can find them here:
http://support.bell.ca/en-on/Mobili..._Nexus_One_for_the_Bell_Mobility_HSPA_network
It says Nexus One but it works for all phones on bell.

settings are exactly as depicted on the bell site, except the apn was called browser instead of bell. changed that, same thing. other suggestions?

Can you tell me the version of gingerbread you're on, where you got the files, any mods to the firmware like pre rooting?
Sent from my GT-I9000M using XDA App

2.3.3, downloaded from here, no mods.

Alright, so totally stock. What's the version code? It should be UGKG3. Have you tried forcing a kies update with a registry hack? Was it one PDA when you flashed it or 3 files?
Sent from my GT-I9000M using XDA App

Yes, its UGKG3. I flashed with the PDA, PHONE and CSC files. I dont really know what you are talking about with regards to forcing a kies update, if you could explain I'd try it out

This has always happened to me, on Eclair, on Froyo, and now on Gingerbread. Whenever my Wifi is active *and* connected to a network, the Data through HSPA is automatically disconnected.
I always thought it was a battery saving feature - if you have Wifi access, and presumably internet access, then you don't need internet through the cell network, right?
So if you're not getting internet access when your wifi is active and connected, then perhaps it's a problem with your wifi router not passing external internet to your phone?

The thing is nothing changed besides the firmware. wifi worked fine here in the house before and no problems connecting to the data network on the go with wifi enabled. I'm really running out of ideas here.

I guess I misunderstood you before. Are you saying you have no data access at all when wifi is enabled, whether or not you are connected to a wifi network? If that is true, something is definitely wrong. That doesn't happen to me with KG3 - just checked.
Have you tried reflashing the modem file? Maybe it got messed up in your flash before?
Sent from my GT-I9000M using XDA App

yes, no data regardless of wifi connected or not, as long as its enabled.
which is the modem file?

just an update, this seems to have mysteriously fixed itself.

no hotspot/tethering

Hi, I'm having problems using my phone as wifi hotspot as my laptop will only pick up the signal for a brief second and then the conection goes. I'm on a tethering plan and used my previous phone no problems thought i upgraded not down graded lol. Has anyone had this problem or know any solutions? Thanks in advance

Same prob
Mine is the same, once I turn in hotspot, laptop takes a while to connect and when it does I get limited connectivity warning and no Internet.
Also, when I restart the phone, playlists on the SD card disappear.

I have only had my z3c for about a week, and just tried the hot spot for the first time. It didn't work, so I fiddled with all the settings that I thought might affect it, to no avail. I then googled, and chased down a couple of pages of suggestions, but still nothing. As a last resort, I rechecked the APN (T-Mobile) ... everything still looked ok, but I decided to reset the APN back to default ... rebooted, and now everything works great!
