Hello guys, I have read many topics about this and I have a problem. I flashed 4.1.2 stock firmware over that same firmware that was installed ( i deleted some files like all share that i need again) and now I can't connect to network, it says it has registered but in the notifications i have Unable to connect to my carrier.
The phone is factory unlocked and i have backed up my EFS and tryed to restore but nothing. The SIM card is working, i tried in other phone, i also tried downloading and installing the original phone firmware also 4.1.2 from Kies, but nothing.
My IMEI is correct, also my S/N is correct, it is not generic or 000000..
I have also tried the ARIZA patch but nothing. I am having the signal and everything is working but i cannot register to network.
How can i fix this guys, and please, don't say search, believe me I've searched alot.
Some more information:
current rom (originally shipped with phone): I9300XXEMG4
One set your mobile network up manually .
Two flash stock rom with correct modem and csc for your network .
Contact your network .
Return phone to vendor or take it to a service centre .

I tried manually set up network, tried manual APN's, also tried flashing stock rom for my network and generic international firmware, nothing worked.
I'll try flashing EMG4 modem to see if it will work.
Edit: EMG4 modem already installed, so not working.
Edit2: I tried ARIZA patch v06, is it only for 4.3 or does it work on 4.1.2 android, i know that v05 is for 4.1.2 but i can't find link anywhere, does anyone have link to version 05 of ARIZA patch?
Edit3: Tried ARIZA patch v05 and IMEI got 00499... going to get it serviced.

Before sending the phone to service center dont forget to reset the flash counter. else your warranty will be dismissed..

I'll take it to local servicer, not to official service, yes i have waranty but it is in another country, and by local servicer it'll cost me around 15$ to fix this and it's better than me going to another country and wait like 2 weeks to get it solved
I had this problem too. Is your SD card slot working?
Both slots (sim and SD card) where broken on my S3.
In the Service Centre they replaced the mainboard. After that all was working again.
Don't forget to reset the counters and flash a original ROM from samsung through Odin.
Good luck.

Yes, everything is working, phone is barely new, guy at the service center got it repaired with some kind of a box called z3x box and it's aproprietary tool that can generate the IMEI with no mather what error it has in efs.

Hi. I recently had some trouble with ROMs, and had to reflash CF-Root with Odin. Now I don't have any signal anymore. Flashed a new kernel, ROM and new modem, and I still can't connect to a network. I can find available networks, however, just not connect to them. Does anyone know the problem? Possibly a broken EFS? I did create backups of my EFS, both by copying the folder to my SD card and with an app. I think I used kTool as that app, but I am not completely sure. I'm a bit afraid to restore it with kTool, though. It says it is dangerous in red letters.
Just restore it with ktool. You can't get in a worse position I mean you're already up for warranty claim if you don't try

It still isn't working. Maybe I should manually move the EFS folder that I backed up? I also used root explorer to copy it, but root explorer says that / is read only.
Did you reboot? Hit the little R/W button up the top for root explorer to be able to paste it.
On another note can you go to setting>about device>status
Can you see an imei number

Is your IMEI correct .
As you have flashed multiple stuff why not flash the correct stock rom for your location and network .Making sure the modem is the right one .
Have you entered your network connections .
Is your Sim Card faulty .

I never removed my SIM card, it shouldn't be faulty. I do see an IMEI number, but how do I know if it is correct?

IMEI: ***************, which is the same as on the box
IMEI SV: 01, no idea if this is correct
Your IMEI is correct, but you need remove it from here.
It's personnal information. Lot of people search valid IMEI to repair their wrong one.
Then what could the problem be?
EDIT: Now that I think of it, aroudn this time they would give me my new subscription, maybe my SIM card got invalidated.
You have correct IMEI so you should not try to restore your EFS backup. I think it's not the problem.
You should try to flash your phone with the latest official signed stock ROM available in our country (sammobile.com for firmware download).
Then, check if CSC is correct for your area (dial *#272*yourimei# to do that).
You're ok in regards to your ers check your slim is working in another phone

Enviado desde mi Samsung Galaxy S3.
I have same problem. I upgraded via kies and i was unable to connect to network. I can see my imei, csc, baseband but still have problem.
the only problem i have is i can not see th product code and serial number. I restored NV_data.bak but still no improvement.
I am stuck and out of ideas.
can you see your baseband OP? i had this issue and my imei showed up, along with all other info, but my baseband was unknown, i fixed it by using the EFS pro app and restoring my nv_data with it.
Hey guys, few months ago I got the not registered on network issue after flashing 4.2.2 firmware
I think it changed the efs to v2 and is not compatible with italian modem firmwares.
so I tried:
- ariza patch, kernel and custom baseband modem
- odin flash with some old and new firmware
- kies initialize
- downgrade to 4.1.2 and update via kies
- flash modems
now...is out there a fu%&£*g genius that has another suggestion? lol
my imei is ok
Efs corruption is the usual cause of network connection issues, unless you have a backup then you will need an expert repair -to wipe the efs, flash a blank then code your imei and serial number back in.

i actually had this just today too. read somewhere in google the following, and it worked for me.
flash an aroma rom (i chose stock archi), tick the flash modem option in the custom install settings.
once flashed i got my data and carrier back. hope that works for you too
I have a I9300 that is not getting any network, the IMEI is 0049... and the serial number is a string of zeros. It was previously running stock 4.1.2 but I wanted to upgrade to at least the latest official ROM - 4.3 and thats how I ended up in this situation.
I've been a Linux user forever and I've owned and flashed a few Android phones in the past but this is my first Samsung Android handset and so the first time I've been bitten by efs. I did lots of reading before attempting the upgrade so I knew to backup the efs partition before doing any flashing. I did this with ktool but restoring my efs backup to various ROMs hasn't restored my network connectivity.
I'm on the 3 network in the UK so when I've been using Odin to restore stock ROMs (I've tried restoring both 4.3 and 4.1.2) I've been using the BTU versions ie
I9300XXUGMK6_I9300OXAGMK6_BTU
I9300XXEMG4_I9300OXAEMG4_BTU
I have now spent four full days reading and trying various solutions suggested in an array of threads on this forum, I've read all the stickies in http://forum.xda-developers.com/galaxy-s3/general/samsung-galaxy-s3-sticky-roll-thread-t2344125 plus many more threads and now I've just about given up. I've tried flashing various unofficial ROMs too like CM 10.2, 11 and RevolutionS5 but they all have no network.
My phone is not in factory mode and I've tried zuluman's patched kernel/modem with 4.3 without any luck. I've tried factory resets, deleting /efs, changing the permissions of and editing nv_data.bin with a hex editor amongst other tricks. No go.
So it seems my only remaining option is to take / send my phone to be repaired or fork out for one of these hardware devices that claim to be able to repair IMEI issues. Problem is then I'm back to square one, I've not learned what I wanted to about my phone (how to safely reflash/upgrade it) and I'll be stuck on whatever the repair shop leave me with.
I'd much, much rather fix this myself as then that opens the doors to experimentation, it will prolong the (so far all too brief) life of my phone and be much more satisfying. Until now I thought the SGS3 was (is?) a class phone and I think its much better than the Nexus 4 I had previously, despite inferior specs in many respects.
I'm sure its possible to recover from this without buying dedicated hardware or at least it should be..
I bought my phone 2nd hand less than three months ago but its no longer under any warranty. Another thing that could be an issue is that I was sold it without a box and there is no IMEI printed under or on the battery.
Thanks for your help!
It would seem from my experimentation that reflashing stock ROMs with Odin on the I9300 doesn't affect the efs partition, or at least the stock ROMs I've been flashing don't repair/recreate efs.
I'd be perfectly happy using the Samsung generic IMEI if it will let me connect to my phone network. If anyone knows how might enable that, please speak up!
Same problem encountered before until now...
This are when the problem starts.
My GS3 International had CynagenMod stable build.
1. I've noticed one morning that my GS3 is stuck in a bootloop.
2. Tried reflashing the stable CM ROM, but still stuck n the bootloop.
3. Tried flashing my stock rooted firmware from my TWRP backup.
- after this, I've noticed that only emergency calls and not registered on network always appears.
- my IMEI becomes now generic with 0049...00 but with serial number.
4. Tried sending it for repair in our local cellphone repair shop. Network signal is fixed now but it always ask for permission for the radio. So battery drain is massive.
5. I didn't send it back. Tried to fix it myself. Installed the stock firmware 4.3 using jellybean. To my surprise, the IMEI and serial number comes back. But still no network signal (emergency calls only).
Lastly, still looking for a fix. If anyone had a fix for this one this will be a great help. Also tried restoring/updating through Kies. All the process I took had failed.
Not sure if the problem was the EFS/IMEI or the modem or radio install from the firmware I just installed.
For now, I'm using the stock 4.3 firmware. The only problem now is the network signal. Any suggestions or fix is a great help. TIA!
I have read of people fixing the no network by flashing a known good efs image but I suppose it would have to contain a working generic IMEI. Please PM me if you have such an image for a i9300. I'll have to find such a thread again and get PM'ing.
I've been disappointed by a few things in trying to upgrade my SGS3.
* There is no well documented fix for this EFS/IMEI/no network issue
* This issue seems to be very common for SGS3 owners who have attempted an upgrade to 4.3 or flashing alternate ROMs yet there is no mention of any of this on
http://wiki.cyanogenmod.org/w/Known_Issues_page_for_i9300
and
http://wiki.cyanogenmod.org/w/SGS3FAQ
There needs to be.
* It doesn't seem Heimdall is able to flash a tar.md5 in one hit like Odin can which is a shame for us Linux and OSX users
Great phone but not for hackers and tweakers it seems.
Sounds like the efs was already corrupt before you tried the upgrade, probably a previous botched repair which only worked on 4.1
Take it to a repair centre and pay for them to recode it for you, there is no other fix. Make sure it connects on 4.3 before you pay.
Suggestion: flash a firmware older than MG4 and let it update OTA or by KIES. Generating the efs-v2-data may solve.
the battle rages on...
rp158:
That sounded like a good suggestion to me so I used Odin to install I9300XXELL4_I9300OXAELL4_BTU, which predates MG4. Because the aim was to try an OTA update, I did not root or flash a custom recovery as I know they don't like that.
Like all the ROMs I've tried since my prob, it installed fine but I get no network. After connecting to wifi I first tried OTA via Settings -> About Device -> Software update -> Update but it just says "Failed to update firmware due to network or server problem". I can browse the internet fine so could this be a problem with Three (my telco)? I've heard of some providers blocking OTA.
So next I tried Kies (not Kies 3) under Windows 8. I went to Tools -> Firmware Upgrade and Initialisation but I just get the error 'GT-I9300 does not support initialising'. Fail, fail and fail!
I've yet to run 'Triangle away' and so I have several flash count points listed on the download screen. Could this stop OTA from working? Is there a limit to the number of flashes you can perform before something nasty happens? I presume its just something retailers check before they refund or repair phones.
Something else I noticed while fighting my phone today was that recovery says the CSC code is now KOR. Could that stop OTA working?
Likes me a good idea to run 'Triangle away': I think there is no max. count for flashes, but perhaps counter>0 and status=custom block the update-procedure. So try after unroot both methods again. (CSC-code I down't know.)
Whilst still running I9300XXELL4_I9300OXAELL4_BTU, I rooted it then successfully ran Triangle Away to clear the flash counter before running csc changer to change my CSC to BTU (from KOR). I would've changed it to XEU but that wasn't an option. I checked that worked fine, which it did, and running CSC changer also (conveniently, in my case) un-roots your phone.
After that I tried updating via both Kies and 'About Device' software update but both just gave me the same errors as before so scratch another idea off my very long list then.

Sorry, too short. Post 5 = repair by Samsung.
So, if I choose to get my phone fixed, has this proven that I will be unable to flash any alternate ROMs on it without losing my network/IMEI/serial again?
Maybe I should've backed up my EFS with philz recovery or dd insteal of ktool, then I might not have ended up in this situation?
Maybe the US/Qualcomm models of the S3 are safe to flash with alternate ROMS whilst the Exynos-based models aren't?
Can anyone recommend a good repair service in the UK if my local repair shops can't help?
Thanks for your suggestions rp158!

No, that's unnormal. But read before flashing, what users say (some beta's or nightlies are buggy).

Official Samsung repair-service.
I thought Philz was the only recovery that gave you the option of backing up EFS? I didn't think TWR supported EFS backup/restore? CWM doesn't.
TWRP can, of course.
A corrupted efs can also effect the stability and use of wifi as mac address etc is also stored there.
Check if there is a backup of your efs. Some roms make a backup of it also - neatrom for example. Try flashing xxemg4 or later baseband to see if it fixes it because after having the later bb you also have efs v2
FIXED
Thanks to everyone who made suggestions in trying to get my phones connection back. Its working again now. My 0049 IMEI has gone, my real IMEI come back and my serial number has returned so I can make and receive calls again!
The thing that was preventing my connection and leaving me to suffer the dreaded 'Emergency Calls Only' and 'Not registered on network' errors was nothing to do with EFS but because I had an incorrect CSC. I had flashed stock BTU roms instead of H3G, which is what I should've used being on Three. As soon as I flashed a rom with the correct CSC, my IMEI and serial numbers both returned and this allowed the zuluman patched modem / kernel combo to work. I'm now happily running 4.3 whereas I was previously on a rooted stock 4.1.2.
There are literally 100's of threads on the S3 forums here with S3 owners ending up with a generic IMEI and no serial after attempting a 4.3 upgrade and the standard response is nearly always 'your EFS is probably corrupt' or 'your EFS in the wrong format'. That will be the case sometimes but I'd bet that more often than not the EFS is fine (if updated) and users have flashed a CSC for the wrong region for their telephone network.
Key tools in getting this prob fixed that hardly get any mention are the csc changer app (downloadable via Play but requires root and also factory resets/unroots when run) and A.S_id's rescue firmware
http://forum.xda-developers.com/galaxy-s3/general/odinfirmware-sgsiii-i9300-prerooted-t1825272/
I'd recommend I9300 users flash A.S._id's ROM if they can't find a firmware with the correct CSC for their network and/or csc changer doesn't restore their IMEI and serial.
Lets fix these forums by getting this info into the FAQs in both the general and QA stickies because I know it to be missing hence the endless invalid IMEI / no network postings.
I'll be back shortly wth more details and suggested additions to the S3 FAQs / stickies.
Thanks all!
I've ended up running A.S._id's 4.3 deodexed 'stock' ROM w/ Boeffla 5.3 kernel and zuluman's patched XXUGMK6 modem.
When I used zuluman's patched XXUGMK6 kernel, I would experience small but frequent glitches in 3G streamed audio. I don't have this problem with Boeffla 5.3.
I'd also highly recommend stock TW users turn off smart screen to massively increase your battery life very easily.
Hello everyone,
First of all i want to thank you for all this guides that i was trying to use here
So here's my story.
I got Samsung Galaxy S3 I9300 with bootloop issue so i decide to fix this by myself.
I was trying to install fimware using KIES but i doesn't fix my issue.
Then i was trying to search for right rom on several websites.
The right one and only working one was 4.0.4 with orange brand logo.
So i was excited that its finally working
Then i realize that my imei is null and my sim card is not working.
So i was trying to restore EFS using several tools and methods.
Finally i got it default IMEI 0049 but it was still not working.
My phone is not qualcomm based model so i cannot use nv item reader writer as it's required to edit IMEI
Even after applying phonutil patch my device is not being recognize as Qualcomm one.(because it's not)
So i was still looking for another way to change my imei manually as i have my original one on the box and under battery.
Finally I realized that i cannot make even Emergency calls it comes with message Out of service area.
So i was trying to apply few modem and radio updates to my phone but none of them are helping.
Anyone have similiar issue?
I have another Galaxy S3 that is working can i copy imei or whole system to my not working phone?
I know that after that i cannot use other device, but thats ok if its possible.

Regarding patch:
4.0.4-I9300BVALE4 firmware is the only one working on my Samsung
Patched modem and kernel that i found and try it are XXUGMK6.
Maybe they are different one or dedicated to my firmware

The reason you can't make calls is because at some point your phone software was on 4.3 this means your efs as changed to efs v2. Now because your current firmware is at 4.0.4 then your efs can't read this because 4.0.4 is efs v1. So you need to get a 4.3 stock rom onto your phone (I know you said only 4.0.4 works) but what are you using install firmware are you using Odin? If so what errors are you getting installing with Odin.
The patched modems and kernels are for 4.3 so they won't work on 4.0.4 or any other apart from 4.3
I was trying so many of them but its always ends with samsung logo loop it doesn' matter if i'm
do things like wipe cache, factory settings etc everytime its not working.
Even on 4.0.4 only this one rom is working.
Im always using ODIN, with KIES its always ends with samsung logo loop.

Ok a couple of things you could try (if you haven't already) I presume you have a custom recovery? Try flashing a custom stock 4.3 with recovery I suggest this >> http://forum.xda-developers.com/galaxy-s3/general/rom-sammys-stock-deodexed-rooted-t2585670 << This is as close to stock as possible but can be flashed with a custom recovery like Cwm,PhilZ,Twrp etc. You will also need to flash a 4.3 modem for this which is included in the thread. If the modem in the thread does not give you a signal (presuming the rom boots ) then keep the same custom rom but flash a patched modem and kernel on top with your custom recovery.
Don't forget to factory reset after flashing!
If none of that works you can always try the rescue firmware here >> http://forum.xda-developers.com/showpost.php?p=30087735&postcount=6 << obviously flash the 4.3 one. Hope that helps
Thank you very much for your help i will try this and let know here if it's working

So it's me again.
I have good news and bad news.
So i was able to install both of firmware with success.
After applying patched modem everything was still working.
But when im calling 112 for example im still having "out of service area" and my imei is still 004999...
So issue is still exist.
I can discover any network when i choose network its even says"registred on network" but then if im trying to choose some number im having error message that im not registred or if emergency call "out of service area".
Any ideas what still can i try ?
Decided to update my GT-i9300 today.
These are the steps I took before I flashed new rom.
Format and factory reset
Wipe cache
Davlik cleaned
Flash new rom
Reboot
I have tried Lollipop 5.0, 5.1 and KitKat all with the same results. Phone keeps losing network connection (Three), I have tried suggestions like airplane mode, delete and reinsert APN detail,remove sim card, switch off phone. I have also reflashed all 3 ROMs twice and still exactly the same error.
Install my backup (Original) Rom and all works fine.
I have the latest CWM too.
Can any help and advise please?
No one willing to help?
I have googled and searched this forum and that is where I found the suggestions that I have tried.
Is your imei and your phone's serial number original?
You can find it in Settings-about device-status
It seems correct to me.
I purchased phone in used condition with broken screen from a work colleague two years ago (no longer works here). I repaired screen but replacement did not have sticker under battery, I stupidly did not remove original sticker or keep a record (stupid I know). Well about two weeks ago I tried to flash a new rom but bricked phone, would not turn on whatsoever. Sent phone off to get repaired (Ebay) but because there was no IMEI number and I did not have box or the original sticker the guy would not repair (which I understand), I located my IMEI number from Google Dashboard and then got a Checkmend Certificate to prove that the phone was legit.
Since it's return I have had this problem. He has flashed an image on which seems to work but no other image that I try will work.
IMEI number is correct as far as I am aware but I am not sure how to confirm the Serial number is correct, any advice?
Just been to an IMEI checking website, inserted my IMEI number and listed serial number on phone and all details came back correct.
Your efs is corrupted and will no longer work with firmware that requires v2 efs.
Only solution, which is what your repair guy did, is to flash the patched modem and kernel -which enables the efs to be read again.
Each time you flash a firmware you will need to then flash patched modem and kernel before you can get connection.
