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.
Then go to #5

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).

Probably. I suggest Philz, TWRP or by TerminalEmulator.

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.

My Galaxy S3 GT-I9305 LTE was running Liquid Smooth 2.37. Recently I lost notification and phone ring sounds and now I have lost baseband and I have no cell signal.
In the phone's 'about' section the baseband field is empty. Android version showing is 4.3.
I'm not quite sure what I did wrong, first to try and get back the sounds and then baseband, I have been playing around with various custom and stock ROMS and kernals to get full functionality back.
I've read tons of help posts but nothing works.
Here's a few of the things I've tried with results in brackets, used CWM recovery to restore working backup (failed 'unsupported file' message),
reflashed kernals (neither Boeffla nor yank555 have worked, wipe/data restore in CWM (it still takes me back to 4.3 with no baseband).
I thought I'd re-flash back to the phone's original stock ROM using Kies, but the weird thing is Kies doesn't restore, it upgrades to the latest 4.3 ROM which fails to restore baseband.
I wanted to send the phone back to the 4.1.2 it came with or was it an earlier ROM? I can't remember as I didn't note it down, I bought the phone second hand, it arrived loaded with a stock ROM for Australia's Optus network. I promptly rooted and flashed the phone to Liquid Smooth and the phone ran fine for months on the 2 Degrees Network in New Zealand.
Anyway, I must have tried reflashing a dozen stock roms I've found online using Odin. Some of them partially work, I get sound back, (it seems only the 4.3 ones work, with the german I9305XXUEMKC reliably loading - it even gives me a NZ english install option) but don't restore the baseband
. All the ones I've found for Optus are rejected, I get the 'unsupported device' or status 7 error in Odin.
So I decided to flash one that works, install cwm, root the phone and try installing different baseband kernals to fix the (probably corrupt) efs.
But I'm going round in circles trying to root the phone. Using CWM, supersu shows as successfully installed, but when I boot into the OS root checker shows my phone is not rooted. Knox seems to obstruct every attempt I make to disable it as well. I keep getting these 'knox stopped etc...from working messages'.
I'm sorry if my description is a bit confusing, I'm happy to clarify anything.
I'm at my wits end. I want to try everything before I have to ship the phone off to a repairer who may charge me hundreds of dollars to fix the phone.
This is I9300 not I9305 Q&A
Use the report button and ask a mod to move to the correct forum .
I can offer no help as i fail to understand the post .
As said before you are in wrong place and are not giving us a clear question to answer. If its a root problem there are fixes for it. Status 7 error is discussed in many threads. Flashing MG4 modem fixes efs problem. Downgrading causes problem. Learn to search before making a thread.
Hello all,
My partner bought a Galaxy S3 (GT-i1900) International (I live in the UK) off a friend .
We noticed that the network connection periodically failed. I noticed that the software was some of the earliest on this phone, and so i thought I'd better update it, as it was suggested that sometimes if the phone is running some of it's earliest software it can cause problems with the network connection, and as it works 95% of the time, surely it can't be the antenna? I went to software update and tried to update it there, it's then I realised the phone had been rooted, and even Kies would not update it. I came to the conclusion that perhaps my friend had tried to mess with the phone some how, and may have caused this network problem, or perhaps was trying to cure it? Who knows
I decided to flash the latest stock rom (i9300XXUGMK6_I9300OXAGMK6_I9300XXUGMK6_HOME.tar.md5) I found on Sammobile. Everything went well, the phone booted up perfectly, the only minor worry being that the first screen was in Polish, quickly remedied by changing the language to English UK. All seemed fine, until we tried to make a call. it was then we realised that there was no network connection whatsoever. I tried other sim cards with other networks - still no connection. It only shows the signal bars.
I read the forums for a couple of days and tried:
Going in Network Settings and searching for my network, 3, which it found amongst all others. it said 'Registered on Network' but then immediately flashed up '3 network not connected' or similar. fail.
Installing CWM recovery, then flashing the 2 modem zips (DDEMG2 & XXDME4) all went fine, but the phone still says 'disconnected' under Device settings Mobile network state
Using the Ariza patch. I tried this, but on the last step where it says 'just click patch' mine gets stuck on a downloading state, possibly as I'm using a stock rom I read some kernel has to be changed first? - Beyond me.
It was then I decided to scrutinize every difference between my working S3, exactly same phone on same network, and my partners.
The IMEI number was correct, something I see people have problems with. The signal strength reading are the same, suggesting the antenna at least is fine.
The serial number - Now this is the ONLY thing I can see that seems to have been changed, from the correct format, to one starting with 4df1 ...... Is this the problem, that has made the phone not register with network? In the UK phones are not locked into a specific phone number /contract and so I don't see how the network would decline a differing serial number?
Anyway that's where I'm at a phone that has no network connection, with a differing serial number.
Any help would be GREATLY appreciated.

Screenshots of the device status in case that helps . SCREENSHOTS REMOVED DUE TO PRIVATE INFO
I've noticed after Googling the baseband version, it says 'New modem DDEMG2 (16/07/13) India,Sri Lanka,Bangladesh'
I live in the UK and have a network free unlocked unbranded International S3!
Surely the steps I followed to flash the modems as stated above are incorrect?!
Do I need to flash the UK one?
Anyone know which one for 4.3?
How do I do it and where would I find it?
Any help greatly appreciated!

Hi couple of things first you have posted screen shots with your mobile no and Imei no on I would delete them
I am pretty sure flashing another rom won't fix your issue you can easily use roms from a different region and still have full network connection but you can give it a try as suggested above.
First thing first because you have upgraded your phone your efs as changed from efs v1 to efs v2 (which you probably already know) flashing the (DDEMG2 & XXDME4) modems would not work because you need a modem later than mg4 for 4.3 roms.
What you need to try is flash a patched mk6 modem and kernel from here >> https://drive.google.com/folderview...sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8#list << flash then reboot if you get stuck in a bootloop factory reset and wipe cache in recovery.You could also try this >> http://forum.xda-developers.com/gal...ii-network-problem-update-sn-t1918601/page199 << look at post 1984 this is basically the same thing with a rom included and as had some success.
If the patched modems do not work and you don't have a efs backup then I would suggest you need to send for repair.

Thanks. I have absolutely no idea what EFS is or how to back up. I would never have usually played with a phone like this it's just my partner was getting fed up of the connection disapearing every now and again, forcing her to reset. I have about 12 hours worth of knowledge on root access, flashing and modifying phones. I am worried I'm going to completely brick the phone. Is there anyway I can make a back of the phone as it is so that if I mess things up I can some how reset it, as at the moment I have Nothing as such. I am going to read up on EFS, I suspect due to the fact the phone was already rooted when I bought it, yet still stuck on the original software and and not updated in anyway, with a pre-exsisting network connection issue, that the phone was already un fixable. I hope not.
I will try all the steps suggested and post results.
Thanks a lot people
ps i hardly have any experience of using forums so sorry if i'm making a mess of this

Don't worry just take your time and read all the guides if you install a custom recovery you can do a nandroid backup which is basically a full backup of everything on your phone and will restore your phone to how it was before (if you do it right) I recommend using PhilZ recovery and flash it with Odin.

Yep that will do fine although you are backing up a partially corrupt efs that's the reason you are not getting a signal because the efs v2 can't read the modern correctly that's why you may need a patched modem & kernel to help read it.But back it up anyway in case the efs gets any worse and gets totally corrupt.

That was my thinking, the IMEI isn't corrupt yet so I thought best to back up what I have. Ive also backed up using CWM.
Im now trying to flash the proper version of 4.3 for my unlocked uK S3, so im at least using the correct os.
Im flashin zip from cwm, but when i select it on my sd card, it says the following:
Finding update package...
Opening update package...
Installing update...
Installation aborted.
Any ideas why it won't install? Iv'e been Googling it
for 2 hours.
cheers
update - I spent ten hours downloading the proper rom 4.3 btu uk unlocked one, finally flashed it using mobile odin.....
started in Polish again - with no network. I think that this is standard.
Next, I am going to try to flash the patched modem.
tallman43 - do you think my strange serial number needs to be corrected? Is this possible or necessary?
Many thanks - one very tired migraine creating finger-nail biter.
Update:
I finally got the phone to work by following the instructions on the page below;
http://forum.xda-developers.com/galaxy-s3/help/guide-fixing-gt-i9300-network-4-3-stock-t2609635
The patched kernel didn't work on it's own, but the kernel I installed from this thread, along with the other two files, seemed to work, and though the phone is now registered using a much better Android 4.3, it still disconnects every now and again forcing a restart. I really wish I could work out why it does this, I'm starting to believe it may be a hardware issue now.
Is there a program that I could use to test the part of the phone that malfunctions and loses signal completely, to try and work out what is happening when the phone suddenly loses all signal and shows only a circle with a line on it (no sign)
Many thanks to all the people who helped me with this I really appreciate it.
I want to close this thread now as what I require now is off topic from the original post so many thanks for your help people.
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.

I tried everything from this guide.
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 ?
Ok, so I used to have cm11 installed, but it got sort of buggy in the long run.
I decided to try Foxhound rom, just for kicks... When it was finished installing, I got the default IMEI and the phone wouldnt connect to the network. I found a way to fix this (without backing up my efs folder), by installing an old rom. After that, I installed ef extreme rom (the one with the s5 ui).. It was supposed to be the most stable and smooth rom... But the camera and hotspot wouldnt work -_- ... I never understood why.
Anyhow, the problem is, now that Im trying to get off that crappy touchwiz rom, I NEVER get service anymore. My IMEI will always go blank.. Now the baseband goes "unkown" too (which hadnt happened before)... For ****s sake, I was trying to go back to my old cm11, and still, crazy IMEI... However, if i install the old rom all over again and the region modem: boom, mobile network works again... I dont understand why it fails to work after i have gotten it fixed over and over again...
I even made a backup of my efs folder when the mobile network is working (on the old rom.. Revolution HD)... When i restore it on newer roms, the IMEI and everything comes back.. however, it wont let me access the network (radio off?)
WTF can i do? Im desperate for help, please!!
@niko: standard is to get your actual firmware from sammobile.com & flash it with Odin … to get a stable base.
Your device serial number is probably corrupted. You can use service box to fully repair this issue. Or you can flash Ariza's patched modem. It will work but your efs folder will be permanently screwed and you will be forced to flash it every time you flash a new firmware.

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.

Thanks for your reply. Decided to try one last time. Flashed CM 12.1 and it seems to have worked except for one thing, my serial number is not the same as before. IMEI is fine.
