[Q] Can't connect to mobile network - Galaxy S III Q&A, Help & Troubleshooting

Ok I need some help my buddy bought the S3 I9300 in India when he was there and it came unlocked and rooted, he asked me to throw a custom rom on it cause I'm pretty good with that stuff, so I got into recovery mode and did a nandroid and then wiped the cache did a system and wiped devalchick cache. Flashed the rom and it was successful and booted up everything worked fine but It would not connect to the AT&t network he cant make calls or send texts tried messing with his network setting and nothing would work, so I restored his phone back to original state and he still cant make calls or send texts anyone know what could be wrong check his IMIE number and everything is there and good everything works good just not the network....thanks

[Q] No data connection after new rom flashed

Hi all,
I've flashed quite a few times before I settled with my current Insanity rom. But then I decided to try out some new ones since I have time during the holidays.
I tried flashing Omega and Delv with cwm (Whatever version they currently have now), both at the startup didn't allow me to bypass by pressing the 4 corners. i thought nothing of it and just continued on and restored my stuff using titanium backup. before my sms, gmail accounts and call logs will get restored but it didn't for both. so i decided to restart my phone to see if it'll come up. it did not. in fact, the data connection goes missing. (i did get data connection when i first loaded up the phone right after the flash using cwm) i only have full bar of signal, but no data.
I thought it was just a rom thing or a bad download, that's why I tried flashing another rom, but once I restart my phone, the data connection goes.
I got so frustrated that I just restored my old (current) rom from cwm.
If anyone can help me on finding out what may be the problem, that'll be great. I really do want to start flashing different roms again because I'm getting bored with my current one.
thanks in advance!

I'm sorry my English award is not very good I am a Chinese.
can you make sure that you have wipe your phone 2 times?
wipe data factory reset and wipe cache partition? before you flash a new rom?
and the problem may be your kernel don't work well . you can flash another new kernel or flash a new cwm
wipe your phone is very important
if these mind can not make your data well you should flash your phone
by odin . use this software to make your phone well
thank you for your reply.
I have wiped my phone very thoroughly: wipe cache, factory reset and even dalvik.
aren't the kernels automatically installed when i install through CWM?
i'm not too sure about this kernel thing as the many times I flashed before, I never had to install kernels on its own through odin. i just flash the zip file of the rom through CWM and it's all good.
so you're saying i should use odin to flash instead of cwm? is there a major difference? i'm much more comfortable with cwm though.
Try flashing a new modem .
Check IMEI is correct .

Have you set your APN settings correctly according to your phone carrier's settings?
Also try your carrier's CSC on your phone.
Set your APN manually, I had this before as well...
Other options is to get the Tweaker App from the Market and when connected via Wifi then it sets your APN as well.

Thanks for the suggestions.
The APN one sounds easier to do. That option's under wireless and networks correct?
Currently, I only have one selected. I'll check it out when I flash the new rom.
What's this csc though??

[Q] ParanoidAndroid (and other) JB ROMs - Can't get mobile network to work

I can't post to the dev forum, so maybe someone over here can help:
I tried the PA ROM, because I really love the hybrid mode. The ROM has worked fine and looks great, but whatever version I flash, the mobile network, both data and phone, simply doesn't work.
It briefly connects to my provider (drei.at) and immediately disconnects, no matter whether I have data connection enabled or not.
Have tried this with all available versions of PA and did the usual routine: wipe, format system, wipe data. I even went totally back to a stock ROM, tried various modems, the current one being XXDLH9, which works just fine on [email protected] 0.6 ROM.
Had the same problem with Omega, FoxHound, and god knows what other ROMs I tried. No matter what, the only JB ROM actually working is [email protected] 0.6, that's it.
Is this a known phenomenon or have I overlooked something obvious?
The phone used to be a branded and simlocked Austrian T-Mobile, but ever since it has been debranded and SIM unlocked.
Any ideas?
All i can suggest is your apn settings?
Can try Offline SIM APN Database (get on Google Play) to insert the correct apn settings.

Thank you for the suggestion. The APN settings on a fresh install, all wiped, are correct and the same as in a working setup.
Any other ideas? Am I really the only one with that problem?
Modem tried APN correct .
Suggest next step is factory reset ..
Step after that is to install an official stock rom .
Others who may have a problem post in the roms thread .

Did a factory reset, totally clean install with everything wiped.
Also, did a clean wipe and installed official stock ROM. Lost root, started from scratch and still didn't work.
I'd love to post in the ROM forums, but haven't yet posted my mandatory 10 postings.. Maybe this thread helps me to reach that limit

Very unlikely since it works on stock ROMs and [email protected] 0.6.
Uhm you just said that it still did not work on Stock?

No, that's not what I said. Stock ROMs work just fine; I actually just flashed the latest leak (DLI5) and had no problems with the network. The problem hasn't changed, so it's what I wrote in the OP: Only JB to work ist latest leak and [email protected] 0.6. All others can be installed but have not network connection other than WiFi.

Have you tried flashing a new baseband? i had the same problem, when flashing the franco. Kernel..
or, go back stock, then reflash the desired ROM
EDIT: If it helps, I speak/write fluent german ('Cause I live in germany ^^)

Thanks for trying to help.
Yes, I have been playing around with all kinds of basebands, trying to flash modems etc. but that does not seem to be the reason for it. I have had different modems working and the very same modems simply did not work with PA at all. Best example ist yesterday's leak DLI5 which I flashed and had a virgin like system working just fine with my network. I then flashed the PA ROM, which then had the same baseband as the latest stock ROM, but, alas, same story: No network.
The weird thing is the brief connect it always shows in the status bar. It lasts roughly 4-5 seconds and then disconnects again, only showing the empty network status display.
It really sucks, because I find the idea of hybrid ROMs really appealing, in fact, this seems to me as a truly superior way of making use of the 720p display.
Need to try logcat next to see whether the connect/disconnect somehow can be monitored from there. Will report on that.

I just installed ParanoidAndroid. I'm kind of a noob to all of this.
I understand some, but not all.
My mobile networks are not working.
I don't get any notification at the top of the screen either saying I'm on a mobile network.
I've messed around with the APN settings. It seems that every now and then it'll connect for a brief moment, but I can't really do anything unless I'm connected to WiFi.
Any help would be appreciated.
I came from a stock phone rooted.
Installed this and now I'm here.
Please HELP!!

Turns out I just had crappy reception at home.
I wanted to get 3+ but something got in the way and had to go with the 2.+
Sorry for not understanding, but what is AOSP? I see that, but I don't get what is what.
ASOP = Android Open Source Project.. They are best but not that much good at battery
Spend some time on xda and Google your doubts.. You'll surely understand everything from android

SIM cantread after Nandroid backup :(

Hi guys,
I wonder if someone can help me with this... really annoying problem!
I was checking out various roms i downloaded here, started with 4.0 aokp which was great, then gave cyanogen 4.2 a try, but then i wanted to go back to Aokp 4.0 cause it seemed to run faster
Now first thing, i couldnt get rid of cyanogen (no offense intended) cause when i wiped all data, cache and dalvik it just took aokp a few seconds to install from CWM recov, that doesnt seem right, right?
Then installed GAPPS, but still it ran on Cyanogen
So, i did a NANDROID backup, which made my phone like before i started with all this..
THIS IS WHERE IT WENT WRONG?
now it just wont read my simcard
i tried my sim in my old phone and that works fine, so the problem is in my phone somehow
is it something about the radio settings specific to my phone and network?
how can i change these settings and are they specific for my provider?
you guys always helped me out so i hope you know what i mean..

I've exactly the same problem.
Are your wifi and BT still OK ?
Is your IMEI (*#06#) still the same as under the battery ?
Was your phone locked ? Did you buy it with a SIM ?
My problem appeared after flashing several different modems/RILS : I got no error warning anywhere, but after reboot, I completely lost my netwerk connection. (no voice calls , no mobile data)
At first I thought a bad RIL driver, so I restored my Nandroid backup from the day before (after wipe cache/wipe dalvik/format system), but still no connection with the netwerk. and can't even make voice calls.
Then I was in panic !
After this I did a complete factory reset, and wiped/formatted cache/dalvik/system/data/SD-card and went in to download mode. After loading a stock ELLA for my region using Odin, still no connection. I was also never asked to enter the PIN-code for my SIM to unlock it.
Damned, this is an embarrassing situation : I can't think of loosing my SG3 for several weeks if I have to send it to Samsung !!
Mu phone is bought without SIM, so it's not SIM-locked.
My Wifi and BT are still OK, my IMEI is also still OK.
Any other ideas, please ?
How do I come in the service mode for the Radio ?
This is the way my netwerk is indicated : a circle with a stripe, much like the famous traffic sign.
Its fixed
So i have no idea how it eventually got fixed but if someone else has this problem, heres what i did:
Full wipe/factory reset blablabla all that
Did Nandroid restore again, put the AOKP ROM and GAPPS back on my phone
Installed ROM which was I9300CEDLI1
Used Odin to install latest CWM, which was already on there, but still
Then booted into CWM and installed .zip of course
This still went suspiciously fast since the very first time it took way longer, that worried me but,
Installed GAPPS again,
Rebooted... IT ASKED FOR MY PIN NUMBER!! hell yes that was what i wanted!
So now it again sees my simcard in there, so now i can make calls end use intnet again!
Still i think it started after the nandroid backup for some reason, or it may have been because of wiping Dalvik Cache?
I have no idea if that even makes sense

Good to hear your problem is fixed !
I'm still not able to make voice calls or enable mobile data : "insert SIM card" is the message I get.
I did already twice a full reset/factory restore and flash a stock ROM using PC Odin, but no avail.
Today I did a restore from my EFS folder using a backup that a had made before the problem appeared, but no avail.
BTW, did you also have the same indication from network status as on my screen-shot ?
Any idea what else I can try ?
I'm getting desperate .....
I'm having the same trouble after doing backup in TWRP when boot up it doesn't recognize the sim card.
I've flash CM10.1 and it only work after i remove the card e put it back on.
Try to see if it something about the simcard.

[Q] Lost automatic connection with my data plan

Hi everybody!
Yesterday, I applied a custom rom to my Galaxy Note and after a successful installation, my data plan wasn't working like it used to be.
I have to say this isn't the first time I have done this, and in the previous opportunities after flashing the rom and rebooting, the EDGE/3G icon appeared by itself detecting my data plan. I never had to configure the APN settings (like it is said in many posts I have seen here).
So, when I realize that it wasn't working properly, I re-flashed the rom but didn't worked. So then, I downloaded the ICS stock rom and flashed it through Odin, hoping it would reset all things here and would give me the initial configuration, but that didn't work either.
I have entered through settings and deactivated/activated the options related to mobile data, but that icon never appears or my data connection showed up.
Forgot to mention that this phone was unlocked through cellunlocker by code, and that I can make phone calls with no problem and also the Wifi works fine... And thank you in advance for any advice/help that you could make
If it's happening with different ROMs then take a look at your modem (baseband). Are you using I717UCLF6? Go to System Settings-About Phone-Baseband Version.
Like ^^^^ said, and you didn't say it, but I'm guessing T-Mobile. So flash any ROM you like, reboot and let but settle in, then flash the Blaze 4G or whatever T-Mobile modem works best for you.
You did enter your APN info?

Galaxy S3 I9300(stock ROM 4.3) not registered on network

I've flashed stock ROM on my S3 cuz i was bored of these custom roms, and wanted stock.
I've installed the stock ROM sucsefully, but I saw Emergency calls only, and when i tried to phone my homephone it won't work, says im not registered on network
I'm trying to register, it says that i'm registered, but still problem
Make sure the firmware matches the device you're flashing. Flash the rom twice with a factory reset in-between and try again. There is also the possibility that you'll need flash something else too, like a patched or original modem..
