Flashed and then lost all non wifi internet access - Galaxy S II Q&A, Help & Troubleshooting

I have rooted my phone months ago but this was the first time I flashed a new rom. now the internet does not work at all. Does anyone have any ideas? I already tried to reflash different roms, reset apn settings to default, reset to stock and even went to ATT store and got a new sim card. Its an international edition of the phone that used to work perfectley.

Your new rom probably doesn't have your apn so factory reset wont help. Google for them and enter them manually.
Could also be modem related. I have an i9100T from Telstra Australia. Every time I flash a new rom I reflash a T model modem and all is good again.

Hi mate,
first of all to be sure make a full wipe before flashing rom (again):
Go to CWM:
1) wipe data, factory reset
2) wipe cache partition
3) mount & storage > format
a) cache
b) system
c) data
4) advanced > wipe
a) dalvik cache
b) battery stats
Then flash rom and reboot.
If then doesn't connect by itself that isn't a fold from flash.
CHEERS ;-)

He probably just needs to make a new APN with the carrier settings.

Google "APN settings >your_carrier_name<" and you'll most likely be fine. If you already have an APN be sure to enable it by clicking the circle next so it greens out ( may be confusing for people with only one APN )

tried changing the apn manually
I tried changing the APN settings manually but still no success. I will try re flashing now but I suspect the issue is somewhere else.

Try setting the network or what ever it is from GSM to GSM/WCDMA.

But you can make calls and send sms, right?

When making a new APN you should input APN name, proxy, port, and server fields really carefully, check once again if it's correct. If you can make calls , send sms , and use Wi-Fi then i seriously doubt it's a ROM problem

Search market for Tweakker as sets up APN just connect WIFI to get set up.

tried everything except modem change
So i tried to download tweakker it says that its not available on my carrier even though I am using only wifi. The only thing i have not tried yet is to reflash the modem. Can anybody point me in the right direction of us ATT modem. Thanks.

Did you try changing from Auto to GSM/CWDMA like I suggested?
This happened to me also, but I've flashed about a dozen times over the past week. I can't seem to find that exact setting now, but I can tell you that the one time I couldn't get data service, this fixed it for me.

So I know you said you already re-entered your APN settings; what did you enter?
Are you using the "wap.cingular" APN, or the "phone" APN? If you're using the "phone" APN, what data plan are you on? If you are using the "phone" APN, and you are NOT on an unlimited "4G" plan, then you won't get data, and should use the "wap.cingular" APN.

I have tried literally ever apn setting i have found on this site, on other sites and the default ones.

Ok - are you sure you have an I9100, and not an I9100T or G or some other variant? You may have flashed a ROM intended for an I9100 when you don't actually have that model... If you have an I9100T, you may need to just flash a modem appropriate to that model. Unfortunately, I don't know where to get them.

[SOLVED]Most Basebands wont give DATA

I cant seem to get anyone to help me with this many roms for example that are on KI4 simply won't give me DATA. I have tried many different roms like for example
Villain Rom works just fone
other rom with different baseband just wont give me data at all...
Is there any fix for this? The H+ icon is just not showing and i cant acces the net (i checked in access points to make sure my APN is OK , everything is just fine over there.
Thanks guys!
EDIT: Problem Solved! All the roms besides AOSP,Villain were having incorrect APN's for AT&T. I had to manually configure and it worked! however i went back to STOCK rom with no root , that is fine for now as the performance is great on stock rom , until ICS oficcaly comes out.
You don't happen to have a I9100T do you?

I have the International SGS2. Now funny thing is i tried 3 roms and only AOSP rom would let me use data , but samsung roms won't that just makes no sence
Start with a stock rom and the correct modem and CSC for your country .
That fails its service centre .
jje
But now another question how come I flashed the AOSP rom which was using same BASEBAND as the samsung custom roms from here KI4
AOSP - KI4 works
Sammy Custom - KI4 does not.
can anyone link me with a STOCk rom for the international version? i was not sure which one to chose because it had different letter codes i belevie my version is UK i bought it on Newegg and its the international version. Thanks guys!
before u go crazy flashing roms/kernel over and over again please try this with the roms that doesnt work:
after u've flashed the roms check that data is not working but everything else is fine.. then install root explorer or use adb to copy "/data/data/com.android.providers.telephony/databases/nwk_info.db" to somewhere else for backup
and then delete the nwk_info.db and reboot
hope this fixes it

Everything else does work besides data. So you would suggest i use the root explorer from my current rom? which is AOSP and copy telephony databases? but would it work with sammy roms?
no no no u first flash the roms that doesnt have the working data network and delete the nwk_info.db ( only nwk_info.db ) and reboot. the phone will generate a new one.. i have had same problem as u when flashing some of the custom/official roms and when i do this it fixes it, also have u tried if wifi works?
ps sry for slow reply i was talking with my gf

I will pick a rom and get back at you yes Wi fi works. Thanks man!
your method did not work :/ is there any other solution?
I pretty much want to say its samsung problem.
I used to use sgs and when I was using stock rom data was really bad.
Then I used cm7, the data became real deal.
I think it may be same for sgs2.

Yes APN are correct. I went back to Villain 2.3.5 and H+ works however the rom feels slow.. this is the only rom that works besides AOSP roms
Would this work if.
I flashed new rom from Villain to any other custom sammy rom? without "WIPING". What do you guys think?
Here is what you can do before you get banned for posting in dev section .
Download correct stock rom modem and csc for your network .
download ODIN .
Reboot to recovery
Mounts and storage FORMAT sd card cache data system .
Phone is now empty .
Remove battery then go to download mode after putting battery back
Via ODIN flash stock rom .
Go to network you are using and find APN settings
Set manually and check APN
In power menu etc make sure DATA is activated on.
TEST
FAILS
Reset rom counter to zero with USB jig then return phone to service centre .

Went back to Stock 2.3.6 Rom. With NO ROOT.

[Q] No phone data after update

Hello guys,
Well i am from Netherland first of all and I got a little problem over here i have a black S2 and was running 2.3.5 official firmware I9100XWKJ3 (netherland) downloaded from sammobile and flashed with Odin rooted with CF kernel, and my phone was working great! But now that 4.0.3 came out i downloaded it pda name
I9100XWLP7 also from sammobile and flashed with odin and using cf kernel again for the root. But now i noticed i can't call, send a sms or anything with internet all the other stuff do work at least well with wifi on ofcourse. I looked on forums saw some threads and telling to see if they had an imei so i went and look and found a generic imei starting with 0000049............ I have now no idea how i can use my phone again to call and so on. Is there anyone here who can help me? I don't know if it matters wich carrier i got but it is T-mobile.
Sincerely thanks!

Hi,
Go to APN Settings, in APN type in "internet"
In username, type in "tmobile"
In password, type in "tmobile"
Try these without the inverted commas, I believe these are the APN settings for the Netherlands.

Well its definitely the APN settings then. I have never heard of them never being saved though. Why don't you just try re-flashing the XWLP7 ROM off sammobile.com again?
Don't root it straight after the re-flash, and if it still won't allow you to input APN settings, I suggest you go back to GB Sorry.

Went back to 2.3.5 and it works as normally so now trying 4.0.3 again without root report in a second
Just thinking, root doesn't have anything to do with APN settings, but it is worth trying the XWLP7 ROM without root to see if you can save your APN settings. Before you re-flash the ICS ROM, write down your APN settings to make sure that you enter them correctly this time Makes it easier.

Even with 2.3.5 i dont get anything at apn list but the data works xD
That is very strange. Can you bare with 2.3.5 then? Or try one of the ROM's in the Android Development thread? By the way, most of the ROMs in there are flashed in ClockworkMod Recovery, so you will need to re-root with Chainfire's CF-Root.
If the data doesn't work after flashing one of them, then I'm lost...
Chris.
Well on 4.0.3 without root it doesnt work neither. So now im thinking what if i go to 2.3.5 how can i get the offcial update through kies? maybe if i get it from kieis it does work

Your very welcome. Also, if you are on a stock ROM (your 2.3.5 ROM) and your are connected to Kies and it says you are on the latest version, either:
1. Try uninstalling and reinstalling Kies;
2. The ICS upgrade hasn't been released by T-Mobile NL yet, or in your country, but I believe most European countries have ICS now.
Chris.
P.S. Sorry I couldn't solve your problem, just never heard of APN settings not being saved, or APN settings not being there and your data still working! Confused!

Well the ics has been released in Netherland cuz i got it from sammobile.com and i got kies now and get the error that my phone isnt compatible with software updates through kies. While i am on stock 2.3.5 it doesnt let me update through there.
i do experiences this problem when trying up ICS rom, however not with samsung official release. I get this problem that no data and cant save APN setting when i try Cynogenmod 9 nightly build.

Mobile Data Not working on new ROMs

Hi,
I've flashed my SGS2 successfully to Cyanogenmod 7.1. Then I wanted to upgrade but whichever new ROM I put (Resurection Remix 3.0.x or Cyanogenmod 9.1) the Mobile Data network will not work.
I have found Samsung stock version 4.0.4 and there Mobile Data works OK. Baseband version is I9100DDLPA. But this stock version drains the battery so fast that I really want to change to something else.
Then I copied all the APN settings from there and put them manually to both RR and Cyanogenmod but it did NOT help, no Mobile Data.
I have found DDLPA modem file and flashed both RR and Cyanogenmod and no luck!
On this site I found the instructions how to extract modem.bin from ROM but I'm not sure if that's the right path to take. I don't want to brick my phone and I flashed it back and forth dozens of times already (almost there to give up).
The phone is bought and used in Dominican Republic with Claro as provider.
Other data from About: Build number IMM76D.XWLPT
Can anybody help?
You said you put the APN settings in manually? Chances are good there's a typo. Like a comma instead of a period, spaces where there should be none, or a password that is lower case that should be capitalized, etc. Double check the settings.

Thank you for your reply, but I think I put those APNs more that 10 times and at least 3 times checked if I read them correctly from the source.
I am having the exact same issue. My mobile data is not working at all once I flash a new ROM, Tried a host of CM9 Nightlies and CM10, and a few other roms too.
I have also tried to enter my APN details manually and nothing happens. After I hit the save button it returns to the APN menu and displays NOTHING.
Flashing a modem does not help either
Not sure what to do??
I'm having same issue on pa cm10 and cm10 unofficial. Just started 2 days ago for me. New modem did nothing APN is correct. Haven't tried stock ROM Odin yet but I don't have a computer

i understand you guys cannot use mobile data, after flashing CM9/CM10 even though your APN settings are set manually and correctly.
Please provide answers to the following questions:
1. Is your problem only related to CM9/CM10 ROMs only?
2. Do you have EDGE + 3G + H, but you cannot just browse because you can't get H+?
3. Did your mobile
mobile data ever worked when you flash a non-stock based custom ROM? If there is any please name them
4. Have you ever faced similar problems after flashing a stock firmware / stock based Rom?
Guys, we'll be doing a lot of troubleshooting, and hopefully, this problem will get solved.

First, try using the reset to default option in the APN menu, this can sometimes takes a while to set so be patient.
If that doesnt work, enter your APN manually but dont hit `save`, when you are done use the `back` button then `home`. Then reboot.
Both of these work for me.

Possible, but highly unlikely... especially if the issue is solved by flashing a modem, kernel, or firmware/ROM. If any solution found here involves flashing one of these things, for your sake, DEFINITELY DO NOT DO IT. You will make your situation worse.
Agreed I wouldn't flash anything unless it was from t 989 or the skyrocket. IM just running out of options and was hoping I would get lucky and the fix would have to do with a certain way of wiping caches or something to that matter sorry to cluster up this thread.

1. Your problem is caused by mismatched Ril and baseband Download Getril: https://play.google.com/store/apps/details?id=com.sibbor.getril&hl=en
2. When you run the app, it will first tell you the recommended modem for your Ril.
- I'll advise to download the recommended modem here: forum.xda-developers.com/showthread.php?t=1277593, then flash this modem via CWM recovery. Your APN settings will stick after a single restart.
- If you are unable to find the recommended modem for your Ril, then you can then download the recommended Ril for your baseband/mourn. Reboot your phone once. Your APN should stick now.
Problem solved
Personally, I prefer the first solution

2. Once the Wi-Fi is off, no icon appears for Mobile data.
3. I had Mobile data working fine with CheckROM REVO HD6 if I'm not mistaken, (it was some time ago and I tried so many ROMs after that)
4. I never had problems with stock ROM.
Thank you for your help.

1. Your problem is caused by mismatched Ril and baseband Download Getril: https://play.google.com/store/apps/details?id=com.sibbor.getril&hl=en
2. When you run the app, it will first tell you the recommended modem for your Ril.
- I'll advise to download the recommended modem here: forum.xda-developers.com/showthread.php?t=1277593, then flash this modem via CWM recovery. Your APN settings will stick after a single restart.
- If you are unable to find the recommended modem for your Ril, then you can then download the recommended Ril for your baseband/mourn. Reboot your phone once. Your APN should stick now.
Problem solved
Personally, I prefer the first solution
Ps: I had already posted this solution for you earlier, but it seems you didn't notice it.

I did a wipe and clean install of ResurectionRemix. GetRIL detected mismatch but the URL you gave us does not have my modem. So I used the download button and he installed the proper modem but still Mobile Data is not working.
I have to add that I can always put APN settings manually and it always stays there after I reboot the phone but no mobile data.
Any other idea?

This flashing stock, did you do it through CWM or ODIN? If you have not tried ODIN yet I would go that route, could just be you need a stock modem.

i am such a tard.. i havent backed up the efs... i did so now after the mess ... i believe there must be someone with tips and a small hope, btw restoring efs make no difference at all, as dont have correct files.
The EFS is fine if you have IMEI, if you have only flashed each ROM once through ODIN you have hope. Try an ODIN flash again. Can you get to recovery to do full wipe first?
Try EFS Pro Here and download to your PC then run it. You will probably need to use your own wireless to get Busybox (free on Play Store) and run it on your phone - if the phone will not go to wireless, DL the files to your PC then copy BB over to the phone in Windows Explorer and run it on the phone.
Then run EFS Pro on your PC (with phone connected by USB, but it will prompt you) and there are a couple of options there to try to see if you can recover things. (NV Recovery and Repair NV Data) - I think the NV Recovery uses info on the phone (.bak file) while repair tries to rebuild the info.
Good luck. Maybe read through the thread first or contact the thread OP if you have questions about EFS Pro processes...

I don't think this will help with the Serial issue, but maybe for the service all you need is the APN/Service info from Vodaphone? Go to [Settings] [More Settings] [Mobile Networks] and check both Access Point Names and Network Operators.
I flashed a ROM and found I had problems so I went to a Telstra page, entered my phone number and it sent me a text with a security code - when I entered that it sent me an install that connected all my services again. Maybe Voda has similar? Or even just a page with APN info?

guys help me out... i am stucked ... any tips? i am willing to try "almost" everything to make it work.
Beyond what I know so far, sorry. If it was me I'd be making sure I have back-ups of everything I can think of (Data, System, Nandroid, EFS) then I would start from clean phone - wipe everything in recovery, factory reset etc. then load as close as possible to the original Stock for the phone. If that doesn't do it, with official stock and counters etc. I'd go to vendor and ask what gives. I'd start with the service provider and if they can't help, phone vendor, then failing that, Samsung.
Maybe some of the more experienced here can assist otherwise...

[Q] Galaxy S III mobile network problem

I firstly flashed Supernexus ROM on my device, tried to turn on "mobile data" to access the internet, the "H" in the upper bar is not existing, I installed firmware 4.1.2 back again, still the same problem, help anyone. :/

That simply means that the HSDPA is weak or not present in your area. Alternatively you can check if your network mode is configured to GSM/WCDMA (Auto mode) or just GSM. If it's just GSM only you won't receive any HSDPA signal.

It has GSM/WCDMA marked.
My mobile is GT 19300 > JZO54K I9300XELLA, before flashing any ROMs, Mobile Network/Paket Data was working perfectly, but I really don't know what happened. :/

Like I said the HSDPA signal maybe weak in your area. If you think that this is a problem with your phone then try doing a factory reset. You can also try contacting your network provider. If all else fails then try flashing a newer ROM as the XELLA builds are quite old.

I've tried Supernexus ROM, it couldn't work, and that was the first ROM I've installed other than the official firmware one, but network data stopped working as soon as Supernexus is installed. I don't think I need to call my network provider as it worked previously. I need firmware ROM, I can't install one on my phone instead of XELLA, can I?

The stock official firmware thread by faryaab contains the latest firmware for our phone so you can look into that. You can also try searching the forums if there is a similar issue with a solution. I'm sorry if I couldn't be of more help as I'm out of ideas too.

Now I'm stuck on Welcome Screen "Galaxy S III" because of several ROM flashes, though I can access to Recovery/Download modes, I tried full phone wipe/factory reset, still stuck. I'm out of tricks.
Return to stock. Send for repair
