[Q] 3G won't turn on ...? - Galaxy S I9000 Q&A, Help & Troubleshooting

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

[Q] No network connection?

Hey everyone,
I recently purchased a Samsung Galaxy S from Sasktel sometime in mid-october. This is the first android phone I've ever had, and after a few days i decided to try to root it. The rooting process went fine and I had absolutely no problems with my phone. However, i eventually decided to try a custom ROM. I went with Darky's Raw Steel Edition from this forum but after i successfully installed it (v2.2) I could no longer connect to the data network. I could still make calls and receive texts, but any sort of internet connection wouldn't work. When version 3.0 of the rom came out I installed it but had the same problem. I thought my best option at this point would be to just restore to the stock 2.1 firmware. I wasnt exactly sure what my phone had been on when i bought it, but i decided that I9000XWJM9 from samfirmware would be my best bet. I flashed with odin, and now I have no network connection at all! Does anyone know what my problem could be? Thanks so much to anyone who can point me in the right direction!
Find your apn settings from your provider or google it and it is is this forum aswell where theres list of them just enter your apn settings for your provider manually.
Go to www.tweaker.com and get the settings for ur network

Thanks for the help! However, I'm having some trouble finding the APN settings for sasktel, if anyone could post a link or something that would be great. And gadgetcheck, I think you gave me the wrong link, it takes me to like a media site with nothing about APN settings as far as I can see.

the SaskTel i9000m stock firmware is JH2. If you're going to use a custom rom, use Doc's. That's what I'm currently using, no issues whatsoever (also on SaskTel in Saskatoon ) If you need the apn settings, let me know, and I'll just copy them out for you, but I'm pretty sure Doc's rom already has them, as I never had to add them. Though maybe they just carried over from my JH2 install?

[Q] Mobile network not available..?

Hello, I bought of a friend a Samsung galaxy s and he said it needs only unlocking,so i "think" i unlocked it successfully.Was putting a O2 Simcard in and in applications i was having then the o2 SIM Toolkit.
But when i tried to make an phonecall, he tells me "Mobile Network not available",so i went to settings and wireless and network and tried to choose an network operator but he tells me then " Unable to connect to this network at this time.Please try again later."
What can I do?
Did you check the APNs?
Please first check if your IMEI is intact. If it is, flash a different MODEM and see if it works. If it's not, flash a fresh ROM using ODIN and that should hopefully restore your efs.
At first thanks for the reply, but now what is a APN? And how do i know if my IMEI is intact?
Sry,am a newbie
For you IMEI you should check your original SGS Box's sticker. There should be you IMEI number printed on. If you dial *#06# you should be able to read your IMEI. --> Look if it is the same as on your box
for apn settings. Apn is your connection settings, how your phone connects with the providers network. you have to check your mobile network settings if these are correct.
So, the IMEI nr is different then on the sticker,and the apn wasnt ticked,so I ticked the O2 and tried but still no mobile network.
Then i need to flash if I'm right?
I was already looking a bit around here about roms etc. But there are quite a few out there,so when you say to flash a fresh rom,which actually do I need to use?
Thank you
Hi again,
because the imei wasn't the same, I flashed it with a new rom (actually two different ones)
But still after both flashes I still don't got my old imei and still no mobile network available. After the one flash with I9000XXJPU he didn't said anymore no mobile network available,instead he said no data network available.
It would be nice if somebody would have some advice or help.
Thanks
hey! don't panic, i have had the the same problem
just download darky's resurrection edition in the development section and flash it. it should bring you back to froyo 2.2.1 and should also restore your imei properly. after this procedure you are free to flash any rom you want

Flash back to 2.2.1
Check imei
Continue on..
Also the problem you had when flashed JPU sounds like you didnt have your APNs correct..thats why the "no data network available"

No Network
Hi!
I have the same problem.
Network is fine (i switched the SIM-Card into different phones), but my SGS GT I-9000 does not connect / find to any network.
I am running Darky`s ROM 4.0.4 v11.0 Black Edition with 3.0.17-Semaphore_ICS_1.2.5s.
Also, the phone says on screen the name of my network provider (COSMOTE), but no signal.
What now?

Recovered from camera problem...now dealing with network issue!! PLEASE HELP!!

A few months ago, i had the non-function problem with my camera after using the firmware update code, on my SG I9000. I resolved that with some help from a friend, by downgrading to Eclair (JM1_JM1_U_JM1.tar) and switching the camera files - the usual method. After reboot, the camera was working fine but appeared the problem with the network - "NO SERVICE".
Till now, I used different versions of android (Eclair, Froyo, Gingerbread) to fix it without any luck.
If you know any other method, i'll owe you one big time.
Thanx!
Note: I have to say that, before having the camera issue, I unlocked my rooted phone using "GALAXY_S UNLOCK" from Android Market.
maybe you can try to flash your phone to the latest firmware such as XXJVU by using odin.
have you rooted your phone again after using different android version? if not, try rooting it, then unlock it with apps from the market, this would fix the "no service" problem.
you could also try flashing it with a different modem.

I tried flashing with different modem but without any good result until now. Today I'll try again with a different modem (something with a file "7zip" transformed in a folder ".tar"...I'm new with this, i know nothing about it so a friend is helping me).
If this doesn't work, I'm trying the rooting method you're telling me about.
Thanx for all!
The JVT modem is pretty god as well. you can flash the tar or zip files by using sgs kernel flasher from market or by odin.

Thanx guys!
It seems that I resolved it, using the I9000XXJVU_I9000OXAJVU_OXA modem (Open Europe). At first, when the phone rebooted there was no signal...it appeared that the problem persisted, but now, after the factory reset (*2767*3855# ) everything seems to work just fine.
Still, I don't remember if SGS signal icon shows the 3G indicator in the upper taskbar (like the SGS 2), because mine doesn't! Can anyone confirm if it's wright or not?
Last edit: It seems the 3G doesn't work, as i tried to access the internet an icon pops saying "No network connection / Cannot connect to internet. Please check your connection settings and try again" - "Settings" and "Ok". If I press "Settings", it takes me to the "Wireless and Network" Menu.
SO, ANY CLUE?
Thanx again!
Have you tried flashing a different modem? What carrier are you on and what modem are you currently using?
Had a bit of a browser glitch, there were zero replies a minute ago.

I'm using an Orange Romania prepay card...and now the installed version is I9000XXJVU (the latest 2.3.6 - Open Europe).
I have signal but without 3G, i think, cause the internet connection doesn't work...only wi-fi does.
with the 3g problem, i think you need to edit your apn settings.
settings > wireless and network > mobile network settings > access point names
this is network specific and you might want to check it with your provider

I got home, set on my SGS the same APN settings from the SGS-2 I'm using now with the Orange Romania card, and it seems to work...at least I don't get the "No network connection / Cannot connect to internet" message anymore and the H/3G icon now appears near the signal icon in the upper taskbar.
I stiil have to run some tests to be 100% sure it really works.
I'll be in touch!

[Q] Emergency Calls Only after CM install?

I've spent the last few days trying to figure this out without any luck. I have GT-S5830D (Canadian Koodo version) on stock firmware TLKI4, unlocked with SpeakOut sim (which operates on Rogers network).
Android Version: 2.3.4
Baseband Version: S5830DTLKI4
Kernel Version: 2.6.35.7-perf-CL568978 [email protected] #1
Build Number: GINGERBREAD.DTLKI4
PDA: S5830DTLKI4
PHONE: S5830DTLKI4
CSC: S5830DTLSKI4
In this stock firmware, I have no issues at all. Everything works fine, can place calls, WIFI, GPS, data all works. If I flash a new rom to the phone, I can see the networks still show up with signal strength showing okay, but the phone will not place calls. Just says Emergency Calls Only.
I've been reading about everything I can about this phone, and I just can't figure out what the problem is. I have flashed the modem with DDKQ7 and I was able to again place calls, however with this modem firmware, the connection was very unstable and would drop frequently.
Is there an issue with directly updating the stock rom to CM7 or CM9 that would cause problems with this baseband? I was under the impression that baseband wasn't really important. Interestingly enough, I have another phone that is the same make and model and is not experiencing this problem. I feel there must be something I am missing, if anyone can shed some light on this, I would appreciate it.
Thank you.
I have a feeling that I may be the only person that has experienced this issue. Continuing to search the internet for other answers, I've discovered that the baseband is the cause of this issue, but I still don't quite understands how it relates. My other phone is on the stock firmware (TLKI4) and is running CM7 without issue, on the same network even.
Do the APN settings have effect on voice calls too? Or is it strictly for data?
Also, I read a post on here that sounded like there was a limit to how many times you can perform a complete flash with Odin? Is that true? I'd love to keep experimenting, but each time to roll back the stock firmware, I need to use Odin and I'm hesitant due to the thought that will eventually brick the phone.
Thanks again.
tried to flash cm7 again??
Yes. I have installed cm-7.2.0-cooper.zip as well as some of the nightly's and still only get emergency calls only. I have another phone, exactly the same setup, and it works without issue. I even tryed GalaxyICS-latest and the same problem.
Now I did install a different modem firmware, and performed the upgrade and I don't have the issue anymore, however I have other issues, dropped service, 3g doesn't work properly, wifi and mobile data won't switch, gps is has extremely long lock time if it locks at all.
Does anyone here have the D version of this phone from Koodo? Which modem firmwares are you using? Anyone specifically using the phone on SpeakOut? Any hints would be helpful because I'm completely at a loss, will just have to keep it stock until I can figure it out.
I had the same problem as you, don't worry though because there is a solution. The Koodo Samsung Galaxy Ace only receives a signal when using the original Koodo baseband. (Basebands have to do with wireless signal, sometimes referred to as modems.) The good thing for you is that you can use any ROM or firmware you like, as long as after installing it you flash the original Koodo baseband (S5830DTLKI4) using Odin. I found a download link for the baseband in this thread: http://forum.xda-developers.com/showthread.php?t=1381595
After downloading, (I'm assuming you know how to use Odin, if not you can find a guide easily) open Odin, and in the "Phone" section browse to the file and select it. (You will have to extract the ZIP) Then press start and wait until it is finished downloading and that should do the trick. If you need any more help post back because I know what a pain it is to try and get this particular phone rooted and install a custom ROM.
ALSO MAKE SURE TO BACKUP IN CLOCKWORK MANAGER BEFORE FLASHING THIS
cause you never know what can happen.
If I flash CM7, it still shows my baseband being the same. It doesn't appear to have been changed. So what I need to do is flash CM7 and then just reflash the baseband with Odin and it should work? Even though the baseband shows the same? I'll give it a shot and let you know how it works out, but does anyone know why this would be required, to have to reflash the baseband even though it was never changed?
Is your current baseband S5830DTLKI4? Because in my experience that's the only way I could get service unless I was on the Koodo stock ROM.
Sent from my GT-S5830 using XDA
Yes, that is the firmware that I'm on. That firmware was installed with the stock rom that the phone came with and I have not changed it. Although I have changed it before, it fixed the issue with getting 'emergency calls only' in CM7 but the service was so flaky it wasn't worth keeping as a solution. If I leave the firmware from stock DTLKI4 and flash CM7 over it, I end up getting stuck with emergency calls only problem.
Is the current official CM7 not compatible with DTLKI4 firmware? Could that be the problem I'm having? I'm still really confused why this isn't working, but I will try to install CM7 again, and then use Odin to flash the DTLKI4 on top to see if the install is causing any issue with it. It doesn't really make sense.
Alright, interestingly enough, I just flashed it again and all is working as expected. I've flashed this phone about 10 times, using the same files and it would not work.
This time however, what I did differently is not root the phone. I've been using the universal_gb_root_v20.zip to root the phone previously, but I found that rooting before installing CM is waste of time as root is enabled in the CM7 rom already.
Also, when I flashed the stock rom with Odin, it usually used selected the KDO CSC automatically, last time I flashed it came up with TLS CSC and had the Telus branding. I don't know if that made any difference. All I know is that it worked and I am able to make calls and use data without any problems.
Thank you Dynamic_Apple, although your recommendation was not required, it did give me the motivation to try again and that was enough to get it working. I've never had so much difficulty modding a phone in my life, especially a model that I have messed with before.
Glad I was able to help, I had just as much trouble getting mine modded too, it makes me jealous of all the generic Galaxy Ace owners, but it's good to know that you can actually get past Koodo's sneaky limitations.

i9305 no mobile signal..what else can i try ?

I Have had this i9305 now without mobile signal, with a vodaphone it did used to show signal but in all cases it always says 'no mobile networks' or 'not registered on network' i have tried with every sim i can think of... it was suggested to flash a stock rom which i did..this made no difference, i then tried installing CM11 and followed the guide to the letter.
I know this phone is not blacklisted as i checked with the imei, i have tried flashing different modems but to be honest im not sure what i am flashing to it..i have tried three different ones now starting with XX as i am in uk...i really dont know if i have missed something or doing something drastically wrong..i have read and read and usualy i would have had this resolved by now...can anyone please help me as i want to give this handset to my girlfriend for a present very soon so we can keep in touch..i am at my wits end with it:crying:
Thanks
Try an emergency restore through Samsung Kies - this should eliminate any software related problem. Sounds to be a hardware problem though so get Triangleaway going and send it for repair if that doesn't work.
Flash 4.1.2, then enable and disable the LTE-only mode hack in the hidden service menu (the *#2263# one, not *#*#4636#*#*). (If you have root, you can also access that menu in 4.3 or even the 4.4.2 port, but it's a bit more involved.)

it won't let me do that as it doesn't list the phone as needing an emergency recovery. I flashed a stock rom and the signal is showing but it keeps saying not registered on network.. if I do a search it finds providers but when I opt for the provider of the sim it just perpetually spins at registering on network.
