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.

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.

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, sorry if this has been answered, but I can't find it.
I recently combined two broken i9300's (one with a bricked motherboard (gets into download mode, product name blank, think it's SDS), the other with a smashed screen) by transferring the motherboard from the smashed one to the other.
It seemed to work fine for a while, but after a week the phone lost signal, showing no service. Rebooting the phone fixed this, however this has now been happening more and more often, and now doesn't have any service even after booting.
Does anyone know what the problem could be, and how to fix it?
Thanks.
EDIT: I managed to restore service again by flashing the stock ROM through Odin (was running stock already), but it lost it again after a few hours.

Check IMEI and serial if corrupted. If it shows your correct IMEI and serial then it's fine. Otherwise you may have an EFS problem.
Report back please.

IMEI and serial are both fine (non-zero and non-null anyway). IMEI matches the label from the smashed phone. However, it's connected at the moment (just re-flashed the stock ROM again). Will update again the next time it loses service.
EDIT: Just lost service again. Only took about 10 minutes after flashing. IMEI and serial are still fine. I also forgot to mention that the motherboard I'm using is from a New Zealand phone, whereas the casing/screen is from a French phone. Don't know if that makes a difference. I tried flashing a French stock ROM, but that gave me an unknown baseband and null IMEI. Flashing the NZ ROM again fixed that.
EDIT2: And another correction. IMEI and serial showed fine after losing service, but I then rebooted the phone. Still no service, baseband is now unknown, IMEI is null and the serial number is non-zero but different than it was. However, I'm sure if I reflashed the ROM again I'd have service for a few minutes, so it doesn't seem like the EFS is entirely corrupt. I'm scratching my head a bit at this one.

Judging from your last two sentences you actally have got an EFS problem. Just to clarify: you get generic IMEI & serial with every other ROM you flashed besides the original NZ stock?
Otherwise it might just be the modem not fitting the ROM, try another (if possible original 3-part stock firmware), but make a Nandroid backup or save your EFS otherwise in case you need it later.

Not generic IMEI but null IMEI. Not sure about generic serial, not sure how to tell the difference. And I'm now seeing the same on the NZ stock firmware after a reboot.
Is a Philz Touch EFS backup sufficient? Anything else I should backup as well?
Well, since EFS is broken already it should be sufficient. To be on the safe site you can additionally save the EFS folder with Root Explorer.
If you have a working EFS you would need to save it with an EFS saving tool like 'Samsung Tool' in this forum somewhere.
Then you got to go through the EFS threads for i9300 and hope to be able to fix this.

I've already gone through all the EFS threads I could find. Haven't seen anyone with the same problem (sometimes it works, briefly, then it stops). Everyone else with the baseband unknown, IMEI null/null problem seems to have that all the time. Was hoping someone would be able to tell me what's different with mine.

Sorry, just meant that I thought somebody might have seen this exact problem before.
I think I've solved this. Used the repair NV data option (to fix broken baseband) in EFS Professional, and it seems to be working fine. Will see if it's still working after a few days though.
My best guess is that this was a file permissions error.

No, not fixed. Worked fine for a few days then the problem came back. Just tried a non-stock ROM (Omega) and same thing. Trying a CM-based ROM now (ParanoidAndroid), but not too hopeful.
Still don't understand why it works for hours/days, then suddenly stops. Rebooting it fixes it the first few times, then that stops working as well (and I get baseband unknown at this point). Flashing a new ROM always fixes it, for a few hours/days anyway.
Sounds like a hardware issue, possibly nand memory becoming corrupt hence why it works for a while on a fresh install.

Any workarounds you can suggest? Just had the problem happen again on cyanogenmod, so that didn't fix it.
Try reading the freezing thread in general forum, see if the memory test tool will compete after a full wipe and fresh install of a stock firmware.
Other than that only a new motherboard, as the emmc chip is damaged.
Hi guys, I must have read a hundred posts about this issue to no avail.
I recently rooted an old S3 GT I9300 using CF-Auto-Root and Odin. I was sure I backed up the EFS folder, but it would appear I didnt. Now I am runnning the Paranoid Android 3.0 ROM on the device with absolutley no mobile network/signal and although i have the IMEI written down the S/N seems to have changed to a generic 15 digit number as opposed to the original RCF**** or whatever it should be.
Ive tried Kies and re-installing a stock ROM which is both hard to get hold of and doesnt seem to want to unzip from CWM Recovery even after cl;earing the Caches and doing a factory reset. I've also tried re-writting the bin file using a hex code app and terminal with no luck, and EFS Pro only seems to make me think ive restored the EFS by backing up the already corrupt one and restoring that....
It is possible to rectify my EFS issue (nv_data.bin file I assume) with only a written down IMEI and no serial?? if so please advise... as Im seriously stuck and although ive considered using a friends efs folder im sure this is probably illegal...
HELP, Thankyou
oh..and...
It occurs to me that the guy to talk to is spocky12, yet i have yet to pm him pending your advice.... thankyou for any help i may receive..
Hi im also in the same position ive tried loads of stock roms for the UK as thats where i am... to no avail ive tried the original 4.0.1 rom all the way up to the latest 4.4.2 rom and each time the imei number is 0000999......... ive tried modem patches most of which are from looking through the xda site but nothing seems to work.... i could never back the efs up as when i had the phone it was in a constant loop so never knew which software/modem/firm it actually had on it as i could not get past the samsung logo. but since i have flashed latest android for the phone it will boot in fine just wont connect to a network and imei number is wrong ive been days trying to figure this out :crying::crying: Please Help!

Hi Dejay, its good to know im not the only one. have you tried using the Kies program to reinstall stock firmware, did that change anything? Also not sure if you tried this http://www.youtube.com/watch?v=JqLK_2I-SBM method but it didnt work for me, the HEx lines he refers to dont exist in my nv-data.bin.
Coincidentally, thats exactly how i acquired this issue, it stopped booting so i factory reset deviced, then backedup and rooted, then installed custom ROM and somehow lost backed up /efs .Im now showing an 000049 IMEI and tried modem patches, stock roms etc. and no luck. my serials all messed up too and i cant connect to any form of mobile network.
I just changed ROM again as i couldnt get the right Gapps to flash with Paranoid Android Rom 3.0 - now flashing Dirty Unicorns v3.8 from here and all working beautifully except no signal, wrong IMEI and S/N - I am by no means a PRO at all this and so im rather stuck like yourself..
Hopefully we'll be saved?!
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).

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

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,
I have a big issue with my i9300. I flashed PDA: I9300UBUGNK1 Brasil version and I decided to root it using CF-Auto-Root-m0-m0xx-gti9300 .
After root the phone was perfectly working, but I uninstalled some pre-installed games which come with that Brasil version from sammobile and after I woke up after several hours I've noticed that there is no signal. In settings > phone info it says BASEBAND VERSION : unknown and IMEI : null.
I tried to flash again, I've flashed different version, nothing can help. The phone is fully functional WIFI works, only no signal, null imei and unknown baseband version. What the heck I can do before smashing it with a hammer?
And I'm talking about home fixes, as I don't have jig & other professional tools
There is no home fix for imei problems, unless you have an efs backup to restore. Take it to a repair centre and pay them to recode it for you, make sure it works on 4.3 before you accept it back.

As long as the phone is not bricked there should be a home fix... Hopefully
Nobody??
Managed to make it working using an efs backup from a different phone. Now I have to figure out how to put my correct imei instead of that one
Imei now shows 0049
This thread should be closed, indeed a very friendly and helpful community over here ....
A mod, please close this thread
Stop whining, you got the right answer the same day you asked.
Cloning your phone by using the efs backup from another phone is illegal and won't fix the problem anyway.

I didn't wanted to clone another phone and hijack it, please let's remain serious. I just wanted to fix ny efs and that's why I used a backup made from a phone which was broken and was sold by parts.
Now everything was fixed at service
Just a question about k-tool backup
After doing a backup with it I have 2 files
efs.img - 20mb and
efs.tar.gz which has 0 bytes and appear to be damaged as I cannot open it.
Is that efs.img enough in case I lose my imei again after a flash or what?
Hello guys, I had this same problem 2 days ago after flashing the GlamourS4 ROM onto my friend's S3. The flashing failed as it was flashing the modem with an "Assert failed" error, however it still reported that the flashing was successful. On booting the phone it had a null/null IMEI and the baseband was also unknown. I even posted about it on xda.. Yesterday, I found a way to fix both the nul/null IMEI and the unknown baseband. I figured that if I flashed modems onto the phone that the baseband "unknown" message would be fixed, and in the process also fix the IMEI. I therefore searched for patched kernels and modems for it. I came across this page that had patched modems and kernels for the S3 running Android 4.3. I flashed the modems and kernels found on the page with CWM 6.0.4.7 one by one. I went through 6 zipped files before the seventh one fixed my IMEI null/null and baseband "unknown" errors. The one that fixed it was "Patched_XXEMC2_Modem.zip". The six I tried at first changed the IMEI from null to 0049XXXXXXXXXXXXX/XX. The seventh one fixed both problems well. IMEI is well now and the baseband is too. Try flashing the kernels and your phone shall be OK like mine.
Null or 0044....... imei, only repair on service with box and tools... In Serbia, cost 10 euro. Good luck
