[Q] lost data connection

First, I'm not too familiar with how ODIN works, so I'm a n00b to Samsung Galaxy S stuff. I'm used to HTC and LG. This is my fiancee's phone.
She has lost data connection. Rebooting, reregistering, turning airplane mode on/off doesn't make it come back. WIFI turns on and all that good stuff.
Here's what's currently running on her phone:
Firmware version: 2.2.1
Baseband version: T959VUVKB5
Kernel version: 2.6.32.9
Build number: FROYO.VUVKB5
Yes she has root. What would I need to do to get this back? If it involves flashing another ROM (been thinking about getting her on Gingerbread) than that's ok I'll just need pointed to a good guide for Galaxy S n00bs.
Thanks in advance for the help.
I'm also not sure if she has clockwork flashed or not. The phone was purchased used and was already rooted.

First go into settings > wireless and networks >mobile networks > and make sure packet data is on, if it is, go into access point names hit the menu key and click reset to default.
Make sure network mode is set to gsm/wcdma (auto mode) if not try switching between the other two options and see if that helps.
If none of that works:
You can try to Odin different modems.
http://forum.xda-developers.com/showthread.php?t=1192436
Try the KD1 modem first and see if she can connect.

I tried the settings already. No luck with those. I will read up on ODIN and try flashing those modems. Thanks.
Might just take the plunge and flash Gingerbread for her, but she hates restoring apps and stuff. lol

I tried that modem. Same issue. Any other suggestions? I'm open for any other ideas. Nothing has changed on the phone. No new ROM, no weird apps. Same geographic area.
I'm at a loss right now. I've never had this problem on any of my phones so I've never had to troublshoot/repair something like this before.

Sorry about the late reply. The IMEI shows up normal. It worked perfectly for a few months, and has only been acting up for the past week or so.

Are you sure your APN settings are correct? for some odd reason, I had to manually set the APN's for my carrier.
Try disabling wifi, as it won't get data connection otherwise. Then go to settings, wireless and network, mobile networks and then Access Points Names.
See if the carriers APN are all set correctly. Should be t-mobile's unless it's an unlocked phone with another carrier.

are you sure that the imei's fine? or is it a generic imei?
i know this situation all to well, my efs folder got f***** and i had a back up on my sd card but as luck would have it my sd card was wiped. and ever since then i could never get a signal on the phone.
so make sure its not that issue because honeslty if it is theres not a thing that you can do about it.

The IMEI is correct. It matches up perfectly. Sorry for the really late reply.
Sent from my LG-P999 using xda premium

So IMEI is correct and data packets are enable?
Do you have a data plan on the phone? Check my.tmobile.com. If you do call tmobile and *****!

Yeah data packets are enabled.
Gotta check those APN's, though. Been looking for what the settings should be.

APN it was!
Thanks! Problem is solved and her phone works fine.

I "lost" my data connection last week and spent hours on odin... N It turns out that I just forgot to pay my bill... I felt like such an idiot =P

The data problems are on 2.3.4 and 2.3.5

OK since I've gotten this phone I cannot get data to work on ANY rom based on 2.3.4 or 2.3.5. Everyone says do hard reboot and pull similar out and reboot and this and that and data never appears. See I have a unlocked g2x and I'm not with t mobile so I think the problem is with that, as others on this phone that doesn't have t mobile
Yes I'm 1000000% positive everything is, right, APN settings are correct and all that as 2.3.3 roms always work with the same set up. So no idea why buy it is like that. I really want CM7 or MIUI and this sucks

Try manually adding the APN's for your carrier.

I do, I stated that in my post. Its not APN related at all.
Sent from my LG-P999 using XDA App

99% it`s sim card related, get a new sim and try again

Try using an app that backs up and restores APN's.

Its not the sim card. Are yal reading my first post? Everything works 100% correct data wise on 2.3.3 , just not .4 or .5 and I'm not the only one with this problem.

Can you recommended an app like that?
Sent from my LG-P999 using XDA App

you know I been tried to install EB 2.3.5 and you are right 100% the problem does lie in the version of android but I noticed that when I first flash the ROM it workes good but if I power off or reboot I loose data but not phone. I noticed that I lose my apn settings it is a APN related issue but it is also tied into the rom. When I try to input the values myself to what they should be I press save and it just never appears in the list. I finally got it working last night I rebooted my phone and it did the same thing and the apn dissapeared and no data and so on. So I saw in a different thread about data issues to try a hard reboot and finally someone told me how to do as hard reboot. So I tried that and what do ya know it worked. So now I am running EB ver 1.08 based off CM7 and 2.3.5 and I have data and everything works perfectly. The next time you loose data try holding vol up and power until the phone resets. I hope this helps a little bit.

So I got that you dont loose your apn settings I did read your post but did you tryt the hard reboot? It cant hurt just give it a shot. Sorry if you did already. Also FatalityBoyZahy might be onto something xboarder has a apn fix that works as well. Also when you install the rom do you follow the steps I noticed that doniq says to wipe cache, wipe system, wipe dalvik,format/system. The last step I never saw on any of the other posts for other roms. Maybe it doesnt matter but I noticed that it is different and I didnt do it the first time because I didnt read.

Same issue but fortunately i was able to fix mine by pressing reset to default on the APN menu then enable disable enable again Airplane mode. Using EB 2.3.5 base cm7 source. Hopefully it works for you.

I had the same thing. It worked for a day or two, but then data stopped. Did the hard reboot and it would fix it for a couple hours at best. I finally couldn't take it anymore and went back to 2.3.3. Like you, I tried everything everyone suggested and nothing worked. There were enough people with the problem that it clearly is a real issue, but everything people suggested were just band-aids, not solutions.

cm7 rom w/ odd roaming???

Hi,
I just flashed the stable build of CM7 to my inspire. Been very happy with it thus far. I came to work this morning (the coverage here is not as good as my home) and I get a notification that I left my home network and I am international data roaming and have no data. My workplace may not be on the beaten path, but is still in the US...lol. Is this a rom/settings issue or does this sound like a att network issue?
Cell reception at my work has been somewhat of an issue in the past, but just seems odd I'd get a message like that.
Thanks!

I had the very same issue. All I did, was redownload, and reflash. Make sure you do all your wipes, though. Sucky, but it worked for me. :/

Rooted, now now data service

I am using simple mobile, I'm not sure if rooting will cause an issue with this...but now I don't have internet access even with the correct APN set up.

What ROM? I also have SM, but have never encountered any problems with data on any ROM. Make sure it's actually on and the APN is case-sensitive.

I remember my data refusing to work once in a while on CM7. Rebooting the phone always fixed the problem. Try that first.

Maybe. I guess you should flash a different kernel - faux123 does wonders. I'm currently running the MIUI/faux combo and it works great.

Ok i've seen that kernel floating around. I just reinstalled CM7 Nightly and no changes, i did a hard reboot so the APN's would populate...but nothing is working. At least with WIFI i can install all the google apks and get the phone set up correctly. I CAN make phone calls without the wifi present, so at least there is that, haha.

So can i get simple mobile to work on my phone with CM7? None of the fixes for the APN are working. I've tried multiple ROMS from different developers.
This one by Faux123, its the 2.3.4 AOSP or something like that, right? I tried to download, but the host website isn't responding.
Is there a way to download the STOCK 2.3.3 kernel for the G2X?

This is why they say to back up first before flashing.
Most of the files linked around here were on megaupload which is now defunct.
Ill work on upping a new one, but someone may beat me to it.
or...just search....http://forum.xda-developers.com/showthread.php?t=1278910

Did your data work with the stock rom and then stop when you rooted and flashed a different one?

SM uses t-mobiles network, and in my area, t-mobile's data network has gone to hell. Most of my friends using t-mobile smartphones have had data issues in the past few days. Quite possibly the same thing might be happening to you?

Simply rename tmo apn name to simplemo, then apn to Simple, mms apn should add smpl.mms, have fun.
Sent via G2X-SINGH-UI

Alright, this is weird. I noticed after a hard reboot that the APN's populating are the T-mobile, and one called SIMPLE, the SIMPLE APN has the same MMS settings and all that stuff but has a proxy server attached, along with some other fields.
This one works, for right now anyway, last night it wasnt. The APN setup provided on the G2X section of Simple Mobile's website isnt working for me anymore for whatever reason.
I'm not too worried about it, i guess. everything seems to be working, i even switched to the T-mobile APN then back to SIMPLE just to test it out.
Either way, I need to get off Simple Mobile.

Need help

I was on Liquidsmooth ROM. Every thing was working fine until I crossed the border to Canada that is when I tried to make a call n I noticed that I had no signal no data. Went into wireless settings and under network mode it was on -home only- tried to change it but it wouldn't stick. Since then I flashed a couple other ROMs no change then I ODINed back to stock factory but still no change. When I'm in USA everything works fine when I cross into Canada I loose signal n data. I think I'm stuck in -home only- mode cause my phone is not switching into roaming. When in mobile networks settings under Roaming it says Not roaming. In Phone Status under Mobile network type it says unknown Service state -out of service-.
I have my phone #
My ERI Verizon is 5
My. IMEI is fine ( the usual #s)

Can anyone help please . I cross the border 2-3 Times a week for a day or 2 n I need it to work in Canada for business n personal use. So please Help

I also tried reflashing the radios but that didn't help either. I upgraded through OTA after Odin to stock factory still no change. Everything works fine when I'm in USA but no data and no cel signal in Canada.
And yes I'm talking about my S3. The Charge is my backup phone.

To clarify, Everything was working fine until you flashed LiquidSmooth?
And then when you flashed other ROMs, and back to the stock ROM, you couldn't get services back to normal, which you had prior to flashing other than your stock ROM?
If the above is accurate, after you experienced your issues, did you flash back to the Nandroid you made prior to installing LiquidSmooth?
Or did you Always have issues when going into Canada?
I found this for now:

The only thing I can think of is try repro visioning your phone with the dialer code. I can't remember it right now, but you can find it with Google. It may not help at ask, but it's worth a shot. I've heard it does reset your phone so have a backup of any data you want to keep.
