[Q] No 3G connection - Galaxy S I9000 Q&A, Help & Troubleshooting

I recently flashed Darkyy's Gingerbread v8 and I cannot receive a 3G connection.
I have selected and unselected the "use packet data" and "data roaming" options as well as downloaded an app to turn on data connections incase it was needed, however still no luck.
I have WiFi connection, signal for messaging and calls.
Any help appreciated as I cannot find anything anywhere
SGS l9000

I would ask the rom developer .

Thanks, I've already sent a message
Do you know if it's safe to do a factory reset? Will this just take me back to 2.1 eclair?

It will not reset to ur stock firmware it will just delete all apps and settings. Did u check if u have any entries under settings/wireless settings/mobile network/access point names/ ? If not u should go on ur carriers page and resend the mms / internet settings.

did you create the APN entry in Wireless settings?

Shrooms and Allgamer - No I havent got anything under APN.
How do I go about that?
(currently searching google - for some info)
I managed to find from my providers website the details for the "Internet" APN my 3G is working thanks for your help.
My WiFi is broke now though. Im presuming this is something to do with settings as well, if anyone knows why this is happening.
I am connected to the network I just have no data coming through.
Thanks

1. NEVER DO A FACTORY RESET AFTER INSTALLING A CUSTOM ROM! - Doing a factory reset will unroot your phone leaving a ROM/files installed on your phone that would only survive if the phone was rooted sometimes causing major issues.
2. Check to make sure you still have your IMEI. Use SGS toolbox (free) From the market. If you don't then use search on xda as there is a fix
3. It might be a modem issue. Try another modem from here http://forum.xda-developers.com/showpost.php?p=9724862&postcount=14434 *If you are a bell, fido customer* or use a carrier that runs the 850 band then you should try to follow the instructions I have posted here http://forum.xda-developers.com/showpost.php?p=10533852&postcount=2525
Let me know how you go

Sorry I've just fixed it, I remembered I installed and APP called DroidWall and I never selected it to use WiFi...Sorry my fault.
Thaks everyone for your help, learned alot about my phone.

Network Error after 2.1 unbranded flashed

Hi all, well, here is my problem.
I have my stock rom 2.1 eclair from Personal, Argentina, and i flash the phone to put the 2.1 ARO (Unbranded). After the flash, the phone works great for a while, then i lost connection, and i coulnt connect to my network anymore. I couldnt performs calls, sms, or whatever related with communication. I only have wifi.
If i access to Mobile Networks -> Net Operators, the phone keeps searching and never retrieve the list of network operators. My apn list is empty, and i couldnt add new ones, mannually or by APN Restore & Backup software. The network mode is not selected, but if i choose one mode, it doesnt selected it.
I Flashed the phone with Odin, with and without repartition, but it still having errors.
Any one can help me?
Factory reset first .
jje
i've performed a factory reste, but nothing happends...
try to deactivate the mobile data and restarting the phone this worked once for me, if that doesnt work i would suggest trying another rom this also worked once for me. And if all else fails then your gonna have to send it back for repair, i had to do that last time this happened. I put on the 2.2 update from my carrier and told them that the phone messed up after updating.
The endless searching for a carrier is normal, but you should be able to enter apns manually. Search for the code to check IMEI and confirm you have one listed.
If you have a backup of your efs file, you can restore that and see if it solves the problem, or load an Argentinian csc file (they may have one in the ROM Kitchen that you can cook as an update.zip) .

I am on ATT and did not have a single issue on this rom with 3G or any other APN related issues.
I didn't even have to detect network to get it to run.

Same with me after running Nav's Mod file. I will try this and reset settings later to see if it fixes my internet issues.
Seriously? Do you have to post a tutorial for this? Are you that desperate for a thanks? Look around there are at least 3 threads with this same info.

Some people need more hand-holding than others. Making it idiotproof has a niche.
i have flashed this mulitple time. fresh. unlocked. rooted. everything. i cant get it to work on my phone, i get a signal and the one bar thing but no data. its fkn gay/weird. i only get this with 2.3.4. anyone know what i am doing wrong or can help me? i woulkd really appreciate it.
Settings for internet if on 3 Network
Ok at first when i go my phone i couldn't make a calls, and when i did the phone would restart itself. So i flashed the radio to 87.00r and it worked.
Then i had to manually set up the apn in order for my internet to work (Mobile Data)
Menu, Settings, Wireless & Networks,Mobile Networks, Access Point Names, create or edit apn.
Name - 3
APN - three.co.uk
ANP TYPE - default
save settings and restart your phone - and that's it really.
I downloaded APN Manager as you stated. I'm in Minnesota, and I switched the APN to one for T-Mobile and got double the speed. Why is that?

How did u flash 2.3.4 and U have your APN set up right and select HSPA and restart. U can check if trying to connect, Go to Settings, to About phone, to Status And Its under Mobile network state!
FOR THOSE ON AT&T
If you are on the AT&T Network and you upgraded to GB from Froyo and didn't delete your APNs or carried them over using Titanium Backup, you should be fine.
For those of you who didn't or installed Navalynt's Mod/reset your data/whatever else you did to lose your APNs, you don't need to download APN Manager in order to get it back.
It seems the problem with the defaulted APN for AT&T in this particular build is that it is missing the password. If you put back in the password, it works perfectly fine. The password is 'CINGULAR1'. So for anyone having problems with their APNs, try defaulting it or just adding the password in first.
Let me know how that goes for you guys
P.S. Can we get someone to mod the default APN to include the password? Or even better, to replace the defaults and add in the defaults from Froyo build? If someone can (or i can try to look into it) that'd be amazing

I screwed up (I think)

Hi All,
Need some help - I've been working more on CDMA phones b/c of sprint, and just flashed my friends captivate (att), but after the flash, have no data or cell service. (I flashed cwm recovery with odin, and then was able to get miui 2.8.3 onto the phone.)
Not sure how to get the cell signal to work, or what needs to be done to get things back to good ...
I see things about flashing back to stock, and then restarting - and i'm lost with the modem files, nothing of them are working so far, but I feel good about it....
--Adrian
Apn settings need to be reset to default... Go to Settings/ Wireless and network/ Mobile networks/ Access Point Names then hit capacitve menu button then "Reset to default".
And if that doesn't work, u probably need to flash an appropriate modem.

Also you can try entering the APN yourself. Just Google the name of your network, and apn. You should find the info you need to create a new apn.

Maybe your APN is wrong.

To check APN
To check APN's you go to settings and goto wireless and networks then mobile networks and then access point names and your carrier should be setup in there if its not go here to find the settings http://ausdroid.net/apns/
A little help from a noob
Well, I've gotta start somewhere. Maybe someone can help push this out from here so more can see it, but I may have a fix that could help. I've have an Evo 4g Supersonic on CM7.2 that somehow lost its 3g data connectivity. Searching searching for APN settings, numerous calls and chats to Sprint (no help), it was finally a call to HTC that helped.
From CM7, I couldn't find a way to update my PRL and Profile. Essentially, those options are "Sense" and not on CM7, so I had to find a way to get to those settings.
Basically, I flashed a Stock ROM (5.07.651.1_Supersonic_Stock_Rooted_CPTB_v2.3-DEODEXED), updated PRL and Profile, then flashed back to my CM7 I backed up before I started this journey.
Works. All is well now. Hope this helps. I'll check back to answer questions if I can be of any more help.
Now, a disclaimer, I'm newish and/or limited in my understanding of how to toy with the Android system, so...as I've noted on many forums across the net, some people will push a "duh, why didn't you know that, noob" kind of approach. Well, go for it, but realize it's rare someone will get on a bike and know how to ride it. We all started somewhere. With that, please feel free to abbreviate, fix, and repost what I have here so this info gets out to the world. This is my FIRST post, so it's likely rife with mistakes. The intention is good.

well .... this is the same scenario with my GT-S5570i ...
Mobile data connection on my GT-S5570i with GB2.3.6 is working fine ...
but after upgraded to Jellyblast then MDC is not working ....
what I did was the change the CSC code ...
To change CSC code on your mobile ...
check your IMEI number by dial *#06# and write it down ...
(u can also check by go to setting > About phone > Status > IMEI )
after that dial *#272*YourIMEINumber# and you will see the multi CSC screen ... (if your ROM support multi CSC)
choose your country CSC and tap on install ....
phone will install and reboot itself ....
after that try your MDC again ....
hope that it should work ....

[Q] 3G won't turn on ...?

I rooted my phone yesterday and when my phone wouldn't boot up the rom I installed, I tried to reinstall the backup I had.
After that didn't work, I used odin to flash a stock ROMI downloaded on the internet and it is working now.
The stock rom I downloaded upgraded my phone from android 2.3.3 to 2.3.6. I don't know if that would make a difference.
So after this was all done, I realised I can't connect to 3g or any mobile network.
Why is this?
How can I fix it?
I live in Ireland so maybe it has something to do with the Stock ROM being from a different country?
Sorry, I am a noob at this kind of thing.
If anyone could help me, I would really appreciate it.
Thanks in advance.

Hey,
The CSC (what country the rom is from) doesn't matter, I'm running a stock 2.3.6 rom from the UK even though I'm in New Zealand
Try first going into
Settings -> About Phone -> Status.
Scroll until you see IMEI. If this is odd (maybe XXs in the number code or its different), then that explains why your phone can't connect to any network. Maybe from a bad flash- there a tutorials on these forums on how to recover your IMEI.
Also in this menu check your signal status- whether it says "Connected" or "Disconnected" in Network Status or whatever.
Alternatively, go to
Settings -> Wireless and Network -> Mobile Networks -> Access Point Names.
In here are your APNs- the network "gateways" that your phone connects to for 3G and so on. Make sure these are configured correctly- if not, your provider's website should tell you how to set these up nicely.
Hope I helped
