Please read before posting read this and that...
I read somewhere that a firmware from another country will not matter, so I installed the Croatian 4.3 android on my S3 and since then I wasn't able to make any calls except 'Emergency calls only'. The 4.3 was xxugmj9, and the modem was something similar but I can't remember. My IMEI and S/N stayed the same, and still are the same! Then I downloaded 4.1 stock rom and installed it via odin - xxemg4 and also the xxemg4 modem. IMEI still same, but no network (I DO have network signal, but it just says not registered on network when I try to dial a number).
I got suggestions that my /efs changed to another format, but I don't have my efs backed up before I installed the new firmware thinking nothing can go wrong... Also when I go to Search networks I can select my nretwork which I use and it gives me a message 'Registered on network' but as soon as I close that I have the '!' mark in my drop-down menu...
So the actual question is what rom/modem, what can I do, if anything, to fix this? ..oh an I've also tried the ARIZA patch, which did not work as well.
I have made an efs backup now, better at one point then never.
Giving screen shot just in case I'm doing something wrong..
You need to install the patched MG4 modem that is floating around here somewhere. Try that for a start

Making a new thread won't change the answers you've already been given.
Flashing random things without understanding them will only damage your phone further, like ariza patch.
Take it to a service centre for repair is your best option as you are incapable of reading searching or following XDA rules .

helo,
i am using samsung galaxy s2 GT-i9100
i flashed cm9 before and then i flashed samsung europe stock.
and now i see, my imei number has been changed.
can anyone help me to revert or change imei again!
Problem i am facing:
1.) call , message not allowed. (Gprs is working fine)
when i call, it says error "Mobile network not available"
i think its becuase my imei is changed to some europe imei now.
i want to get my real imei back , to make calls etc.
so, can u suggest me things to do?
did you make any efs backup? if you did then just restore if not... then it will be really difficult... there is few threads about it around somewhere in this forum ( seen it few times ) use search and i wish you good luck
ps. next time install ktool from hellcat and backup efs
Try this http://forum.xda-developers.com/showthread.php?t=1261948&highlight=imei+unknow
Hi all,
hope someone can help me. Since this night I am no longer able to connect to my mobile provider. I tested the sim in a different phone and the sim works fine.
When I go to settings, and search for the providers, I get all german providers but when I try to connect, it says it is not possible.
Is there anything I can try? Or could it be that something in my device is broken?
I have JellyBam CM10 4.12 running, but it seems to be not Rom-related.
Any help is appreciated.
Thanks!
Check your IMEI in settings/about phone/status. If it begins with '0044' (do not post your actual IMEI or any portion thereof here !), there's your problem. If that's the case, restore your EFS backup (there are heaps of threads about same on here).
Also, there's always the possibility the phone has been IMEI blocked (assuming your IMEI is correct/OK). If your IMEI is correct/OK, call your carrier & confirm your IMEI is/isn't blocked.
If neither of those things are the issue, I'd do a clean install of stock in the first instance & see if the problem persists. If it does, it may well be a hardware issue. If going back to stock does fix the problem, it's obviously a rom issue; maybe try a completely clean install of the rom you were using & see how that goes.

I tried everything except calling the provider.
My IMEI and Baseband is still visible and ok.
If I search for networks, it finds the networks, but says "Unable to connect".
This happens also with stock ICS firmware as well as with the custom ROM.
Does it mean, that my hardware is broken?
Not necessarily. But call your carrier & ask if the phone is IMEI blocked. It could also be a case of something not setup correctly at their end so far as your account with them is concerned.
That's what's you need to do next.

Ok i called and they tell me that they dont block IMEIs...
Tried another sim and this SIM doesnt even ask me for PIN entry??
Whats wrong`????
Well i'm quite disappointed now, I tried flashing various roms (custom and stock, ICS, 2.36) but still no luck.
I also noted now, that I have unknown baseband and no IMEI since yesterday.
I had a backup of EFS folder, but restoring it didnt change anything. Using EFSBackupPro...
Dont know what to do else...pleaasseee help
tgat diesnt sound good
Try restoring stock via odin

Try restoring your efs folder manually , with a root file explorer, if you have your efs folder backed up on your external SD card copy it to the root directory of your phone
i have restored the EFS folder from my girlfriends phone (just to test, because i have only an img of my backup)
No chance, still no Baseband/IMEI...
Seems to be a hardware issue? Or should I try to get professional help (JTAG?)
Should not be using another phone EFS on your phone. Data are different in them.
hi there!
Ive read all I could and despite coming across several similar problems, haven't found an answer (so if anyone has an idea, plz help!)
I'll try to be as concise as possible:
I have a message that says: not registered on network
I have a China Unicom galaxy S3 (international model, gt-i9300) not copy, original version, bought from service provider store, running forever on android 4.0.4 (no updates available, via kies, or software update whatsoever)
As you know, because it was bought in China, it's blocked from factory settings (no svoice, google play, among others and of course a reduced overall functionality and an alarmingly high used of RAM despite of every app being closed) and even you can download most apps, they're in Chinese and they're different and not completely working versions of them (i.e. fb, skype,...)
Read and read, until managed to do rooting via heimdall (only have mac available), once installed SU, managed to download and install google play, but it kept on crashing, along a previously (VPN only) functioning fb app, and twitter.
After a while of more research I came across odin mobile, and by downloading an international ROM from Hong Kong via Sammobile, managed to install 4.1.2 from HK (I9300OZSEMC1). Despite the now no restriction phone i had, i came across a problem: cannot call or message or use mobile data, only with a message that says " not registered on network"
I did check the sim card, and selected the network manually, without success.
I checked the AP, CP and CSC and they were unknown.
After much frustration i remember i had a backup if the original carrier, and after re-rooting, managed to get back to the super blocked version of it, bu t the problem remained: not registered on network.
I checked again the ap, cs and csc and now are back to factory default (just like they were before all this odyssey began).
I changed the sim card to my gf's iphone and it works there, just not on the galaxy....
I repeated the above two times more, using roms from HK, Taiwan and UK..... same problem, even when going back.
Any ideas? I'm quite desperate now
thanks!!!
Is your IMEI the same as under the battery .
If not restore your backed up EFS folder.
No backup = service centre .
Do you have the correct modem and CSC for your network .

yes, imei is the same
before doing all the process, i verified and saved screen captures of how it was before and after, both pictures coincide, but still nothing...
(what is EFS folder? , i've done this with little knowledge on the topic, so i've no idea what's that ^^"
I guess service centre might help, but well, since this is China... i expect the worst.

I'm assuming you may have changed the modem during the flashing of the HK fw, try finding a Chinese Modem and flashing that. TBH this is why people tell you to read and read again before rooting and flashing custom roms.
Hello guys,
I`ve been watching all this topics for a while cuz I have some problems with my Galaxy S3. I`ll tell you what i did.
All worked fine, had the 4.1.1 official rom + root, then i wanted to go to 4.1.2 so i flashed an UK stock ROM. After that i kept getting the "Sim has been removed" error need restart bla bla.. so i search all around for a fix.. i changed 2 SIM cards and nothing. Then I flashed a Poland version 4.1.2 Stock. That version was better but I encountered the "Call ended" error.. calls would end after 3-4mins or i could not call at all. Then i flashed (and this is when the problem started) Stock Vodafone Spain and got "No network". I must say my IMEI/ SN all are intact.
Then I patched only radio modem from the UK ROM with Odin, but with "PHONE" option (i know i did wrong).. i wanted to change only the modem and it worked cuz i checked with *#1234#.. but from that moment not even one ROM has worked in showing me the network. On About phone says "Network: Unknown". Sometimes it connects to Vodafone but when I try to call says "No network service".
Now my phone is in second service and they can`t make it get a network on. They tryed the neverlock thing but i think was already unblocked.
I tryed rooting and using this Ariza. and were 2 versions there.. I tryed v5 only and didnt worked.
I tried the ##72786# and I get the following message: Connection Problem or invalid MMI code (found somewhere that for this code i need to have Wifi on to work?)
Now i`m thinking to get my phone back and dunno reflash with a good .pit file ? or just reRoot and try v4 Ariza.. I`m really sad, it`s been 5 days and I can`t think on nothing else to do.. I even called Samsung official service and they said to send it to them.
If you have any idea, pls need help. tnx
Check your IMEI is the same as under the battery .
Samsung will reject warranty .

you are right.. IMEI and SN are not the same.. pff what to do now?
Restore your backed up EFS folder.
jje
But i think i backed up the EFS folder with the modified IMEI. What can i do now?
nothing. replace the motherboard
SOLVED!
Ok so tnx to JJEgan i checked all the IMEI numbers and only 2 of them were modified. Thing is before I pached the v5 Ariza, I did a EFS backup with that program. That backup img saved my phone.
Firstly I got my phone back from service with 4.2.1 official ROM (thats nice, cost me 0 $ ). I rooted with CF-Auto and used Ariza patch (v4). But my imei was still wrong so after that I used EFS_Backup_Restore_new_ADB.rar to restore my IMEI/SN with the old EFS backup then I used another programEFS Professional v2.0. I checked the option to repair No network and clicked Restore. After that I restarted my phone and I got the messages from provider with APN settings and so on.
Thank you for the help :good:
worked till first restart... now No network again, I`m not a samsung/android fan anymore..
I recently rooted my i527 then unlocked it for use on T-Mobile, And it was working just fine, Getting Signal and EDGE, So earlier this morning I took out my sim card and rebooted the phone a few times, Changing the APN from epc.tmobile.com to fast.tmobile.com thinking that was going to get me from going from EDGE to 4G or LTE... Yeah Right! Little did I know, It requires a lot more than just changing the APN.. But thats beside the point.
Anyway, While I was taking my sim out and rebooting, After once or twice of doing this, The phone would not come up with T-Mobile signal AT ALL. After a while of just blankness it would pick up What Im guessing is WCDMA signal or something, But not T-Mobile Active signal like it was doing just fine before. So after 20 or so reboots (thinking that was the problem), And looking around, I noticed that the phone is not issuing a IMEI number. Not in settings, and not *#06# either. The IMEI number has been lost. When I go to settings to view it in About Device it just says "Unknown". I'm assuming this is my problem, Once I get the phones IMEI number back, It will pick up T-Mobile signal again.
At the beginning of this, I was simply trying to get high speed data on the device.. Now I can't even make and receive phone calls. :crying: Any help on how to recover the IMEI would be great, and highly appreciated.
Thanks

If you still have the unlock code try reseting the phone using kies... then see if your imei comes back..
Used ODIN to install correct ROM. This might help.
Get your officla ROM from http://www.sammobile.com/

SamMobile still doesn't have AT&T sgh-i527 firmware. Use kies to recover your phone or odin with the posted firmware on this forum. Kies would be the safest.

You will need Microsoft .NET Framework v4.0 installed on your computer Use efs professional on your computer found here http://forum.xda-developers.com/showthread.php?t=1308546
make sure you have root and install busybox on phone. run the EFS Professional exe file from the downloaded file from link i posted there will be a pop up window with three options pick the efs professional tab give it time to connect you will need to give permission on phone for adb if all done right it will say ready on program. across top of the program there will be four tabs click the qualcomm tab now there will be more options click on qualcomm nv tools tab let it connect. now there will be a new window for qualcomm nv tools hit the connect button now you will see your imei at bottom if your imei is not there put it in imei box and then click the write tab. hope this helps.
