[Q] 3G connection gone after froyo update - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi....(I am new here)
So what happened was I factory reset my phone before upgrading it to froyo. Now everything seems to be working in order, making calls, receiving texts, wifi all good. But no data internet (3G or 2G). The phone was rooted before and installed a lagfix (OCLF ryanza).
I have tried settings>wireless and networks>mobile networks and tried all options there and rebooting phone several times but nothing worked. Please help. thank you.

Take a look at your APN settings, mine disappeared. Press menu then restore if it's blank and they should come back!

it worked.
totally missed that one.
thank you.

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] Captivate lost ability to use 3g data

I do have 200mb of data on my plan, running Mosaic 8, and up until recently everything was fine
I primarily use wifi, but the day after Christmas I saw my data stopped working...
If anyone has any suggestions to get it working again, I would appreciate it
Try: Settings, wireless and network,mobile network settings, access point names. Then hit menu Button and reset to default.
May wanna try flashing a modem, or a few.
Thank you very much! I figured from reading around it might be something with my APN, but I knew little about that subject. Plus, I forget to try pressing the menu button on the settings menu
But thank you for your help, the "default" and a reboot fixed the issue!

[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
1 flash darkyrom 10.2 re
2 alliancerom jw4
3 then jw8
