Hello! I hope i started this in the right thread?
Ive had problems with my phone lately. The problem is that i cant make phone calls and text, it says "Emergency Calls Only"
When i dial *#1234# in the dialer it says my CSC is unknown? May that be the problem?

As you dont get network, Check your imei number in about>settings. If it says unknows then you need to restore efs from a backup.

My IMEI is just fine, tho my EFS folder is empty?
Check that your mobile account isnt limited or restricted.
Check your sim in another phone.

I had the same problem once with my phone. Turned out to be the SIM card was shot. Had to get a new SIM.
Maybe a solution
For Unknown CSC:
I had the same problem but since I used a MULTI CSC in my ROM I had to select one to be used.
So in the dialer I typed in: *#272*YOUR_IMEI_SHOULD_BE_TYPED_IN_HERE# and then select the one you want like XEH or XEU, etc.
After it the phone will reboot and maybe will do a wipe but I'm not quite sure. I cannot remember anymore.
Hope I could help.
Ive tried other sims cards inside the phone, nothing new. Ive basicly tried all the basic "trys" but nothing helped. And i dont have a EFS Folder back-up im afraid . . .
Thanks for the response!
My suggestion would be to flash a stock rom and see if it rebuilds the EFS folder .
If it does follow rule one backup your EFS zillions of posts on it .
Note
you do not give us a clue regarding firmware or what you have flashed ion the OP .

Just Change CSC to your country CSC and flash Stock Rom
Hello,
If you are facing issue about CSC than change it to your country/region specific CSC and flash stock ROM. everything will be fine than. All the Instructions and Stock Rom for specific region is given in the below link.

I followed this guide ( http://www.youtube.com/watch?v=ihFRsquw_8E&feature=g-hist&context=G2816d54AHT2JnXgAAAA) to get the official ICS update.
I know the update was for Nordic countries and I live in Sweden so I flashed it through odin.
Now I can't make phone calls, send text messages or connect to my 3G network.
I asked the uploader and he said "Go in to recovery mode and wipe cache and factory reset" so I did.
The phone then started up in Polish and the problems were still there.
Can anyone help?
Try entering AP settings.
Have you checked for service, do you see your imei number in 'About Phone'?

Have you backed up your EFS folder before flashing?
What you have is a standard IMEI, meaning, that IMEI is for phones that are displayed on stores.
First, try re-flashing the package. If that doesn't work, re-flash only the modem.
If even that doesn't work, follow this guide : http://forum.xda-developers.com/showthread.php?t=1264021

I dont think I have since I don't even know what an EFS folder is
I am going to try all of these.
By the way when you guys (assuming you too have an 19100 and have upgraded to the official ICS rom) press and hold the power button, do you get the menu for silent mode, 3g network, shut down etc or does it just shut down immediately?
My friend have a similar problem too, he got a problem with CSC Unknown and he can't call, text and all phone features....
The real problem where i can find the flashable CSC files because all link are dead

Well... You should ALWAYS backup your /efs folder. Your /efs folder is literally your phone and is what distinguishes a phone from a gaming mini-console
I have that menu, and I'm sitting on LPB, waiting for something more stable LPB...
Always always always backup that damn EFS folder
That imei number is a generic one so you have lost your unique number.
Try this threadhttp://forum.xda-developers.com/showthread.php?t=1264021
There are others to search for. As a last resort search for odia. He/her has the knowledge to fix it.
Otherwise return for jtag repair.

I'm sorry to hear you lost your IMEI but I hope this will teach you to inform yourself better before doing something like flashing in the future. Anyway simply reflashing the firmware might help it, it certainly helped me twice.
If you get it back make sure you back it up, so you wont have to go through this again.. There are a bunch of apps that can do it for you so it really isnt all that hard.
Anyway, good luck!

Tried reflashing the package, and it doesn't work.
I only have one big (622 mb) .tar.md5 file, should I flash that in the modem?
I am having the exact same problem, although my IMEI number seems fine. By that I mean it is not the generic one previously posted.
I can not connect to my carrier network, or do anything else network related for that matter.
My phone also turns off when I tap the power button once, I do not get that standard menu.
Any suggestions?

Here's the fix: http://www.youtube.com/watch?v=iY9cDkj4CCw! If it works, make sure to make multiple backups of your efs folder on sd card/pc/drop box etc!! You can view your efs folder using the Root explorer app!! Here's the download link for the kTool fix: https://play.google.com/store/apps/details?id=net.hellcat.droiddev.ktool&hl=en! Good luck!
i was working with gingerbread cool then i came to upgrade to ics my mobile is unlocked version now i`m facing "no service" and some times it tell me it can`t find the carrier any help guys..

probability is that the CSC would not have a clue as to who your network is enter network settings manually .
Modem is a question of try each .

Hi guys,
I'm having some problems with my galaxy s3 GT - I9300, it all started when i tried to unlock it via GalaxSim Unlock.
I started the prosses regulary, making a EFS folder back up (the original EFS).
Then i tried with annother sim but it did not get signal.. here is where I mess up.
I make a factory reset and I lost the ORIGINAL EFS back up.
I make another EFS folder back up, but that back up is not the original, is the one that GalaxSim installs.
My IMEI is the same that the one in the box, also my S/N is not 0000..
So.. I'm wondering if you can help me, maybe i can send you my efs folder to see if it is something wrong.
Thank you very much. I hope someone can help me.
PD: my phone was locked to claro URUGUAY. I'm on 4.2.1 stock
a factory reset does not affect your EFS folders, hence it is still your original EFS folder.
not sure if the sim unlock tool touches the EFS folders though.
flash 4.1.2

Ok.. so if galaxsim dos not touch the efs folder, it's the original one.. but i don't know if galaxsim change something or not.
Other thing is that my 3G works, but I can't make any call. It says that I'm not registed in the network
That says wrong IMEI or user has not put network APN settings into phone in most cases .

I'm gonna try ariza again, but some where i have read that is needed a super wipe.
When I try it, I only installed the .apk but it didn't work..
So, it's needed a diferent rom, a wipe or something else?
Hello lads. I have really really big problem with my I9300. I upgraded jellybean from 4.1.2 to 4.3, everything works perfect, but one main problem appears, I can't call, and receive phone calls. My samsung says that i'm not registered on network. I tried to install modems I've rooted device, and nothing happens. Today I decided to downgrade 4.3 to my previous 4.1.2. And surprise surprise, same problem Not registered on network. By the way my IMEI is normal. What should I do next? Any advices? Thanks

Hi.
Check for your Serial Number.
Go to, Settings, More, About Device, Status.
If it's 0000. It's corrupted. Also check for Baseband sometimes it shows unknown.
You have corrupted your EFS.
Backup your current EFS before you do anything from this point forward. You can try using PhilZ CWM.
Best bet is try to flash latest 4.3 Rom using Odin.
I9300XWUGML4
Try to restart your phone.
Yes, my serial number is 000000...

Same problem here. In my case, the problem is slightly different. the phone was a XXEMG4 that i had to downgrade to unlock and consequently recover IMEI. After recover IMEI (I didn't make an efs backup…) i upgrade to 4.3 and can't register on network.
I've been making a lot of research on the subject and i understand i should made a backup of the efs, but i didn't…. My question now is:
Is there any possible way to restore the efs module in v2 permanently, so we can flash another rom without losing it ?
thats the 1.000.000£ question for me

Your efs is corrupt, patched modem may enable it to again be read but will have to be patched reach time you flash new firmware/modem.

Makes no sense, you can restore a backup at any time. If you've already corrupted efs without making a backup then things can only get worse if you don't start making backups before you flash.
Lads. Now my IMEI and serial looks alright, but there's still one but. Internet is working with my SIM card, but I still can't call and send messages. In status:
Network: Meteor
Mobile network type: UMTS
Service state: Out of service
Signal strength: -99 dBm 7 asu
What should I do now? By the way, I've tried to reset factory settings, restart couple of times, when I'm trying to register on network, device says me TRY LATER. Oh, and when I turning my phone on, and PIN shows, it saying that my SIM CARD IS LOCKED, EMERGENCY CALLS ONLY
Sim locked to network ask your vendor to unlock .
