Hi guys, my phone (Galaxy S3 i9300 international) was repaired at service centre with z3x box after dirty downgrade from 4.3 t 4.1.2, i lost my IMEI, than when it was fixed, my phone was on 4.1.2, now i cant update my phone to 4.3 because i will get the emergency calls only again, after i tried repairing it and flashing with stock 4.3 rom via Odin but again emergency calls, then it was repaired again and put on 4.1.2 android, but i don't know why can't i upgrade it normaly without getting emergency calls, i tried also backing up .img of my efs partition when it was working, and restoring it on 4.3 but emergency calls was showed again, my imei was not broken, i just got emergency calls, tried flashing the patched MG4 modem but then my imei was null/null and i got it serviced againn. Yyes i have backed up my efs it is working now and i am on 4.1.2
Guys is there any chance for my phone to go on 4.3 after servicing with z3x box, i heard somewhere that i am now stuck on 4.1.2 forever, is that a sad truth?
Update: I can switch on whatever 4.1.2 ROM if it's MG3 or lower (EFS v1), after flashinng i get no network, i run ariza patch and it works, but ariza patch won't work on 4.3 or MG4 newer ROMs.
I also tried zuluman patched kernel and modem, and nope, no results, still no network.
Bump. Help please?
Your issue is the repair made your efs folder incompatible with all newer firmwares, a patched modern AND kernel may enable you to update -from what I've read the two are linked.
Failing that you could wipe the efs folder, flash a blank (someone posted a link the other day) then get a reputable repair to program the imei and serial numbers back on. A lot of repairs seem to fix by downgrading and Ariza, which is no use for efs v2.
There is a thread in general on restoring your imei, but hardware is required.

Thanks for the reply, i'll try to mix something up.
Oh, and one more question, does that all mean that i can never be on full stock anymore? I mean having 4.1.2 and normally upgrade to 4.3 with a normal efs update through installation?
With the first option no, you cannot use unpatched firmwares and your efs remains v1.
The second option might work, but depends if a repair can write to v2 efs.

Hi, basically i tried to update my s3 to a custom jelly bean software and during the process, i got no signal. I then got my friend to look at it and then he rolled it back to 4.0.4 but now there is no sim in the phone and it says no service? Also, there is no imei number or bluetooth number and the phone doesnt connect to wifi? What should I do?
Reboot into recovery, do a factory reset and see if it works then. If not, try reflashing a stock ICS ROM.
nope didnt work
try to flash stock ROM and kernel with ODIN....
BAD NEWS

You wiped the EFS folder... that's not good, not even close
If your phone is not the intl version, and you got no signal after flashing the ROM, you most likely reverted the soft unlock (which involves altering files in this folder, which is in the root of Android on most sammy devices) - that's why you didn't get a signal (or maybe you just didnt have the right modem flashed with the rom you downloaded, but this is unlikely)
And when your friend rolled back he wiped the EFS folder by accident, or tried to unlock your phone and screwed up without having backed it up first
My friend, i do not know if these folders have files specific to each device, if not, just look for a backup on the forums and paste it in the root folder of the device, otherwise, you are beyond ****ed up, you may have bricked your s3 (or maybe your friend did)
Please write back if developments occur
EDIT: The only solution is to take it to a service center and *hope* they repair it, as modifying the IMEI is likely ilegal (and talking about it is against the rules of XDA) - The EFS folder is DEVICE SPECIFIC, if you didnt make a backup you basically bricked your phone... i'm sorry my friend, i hope the SC can get it done for you
Hi all. I rooted my phone couple of weeks ago and I didn't like the rom that I flashed and I decided the unroot my phone. So today I tried to unroot my phone and applied triangle away solution. Everything went perfect. I flashed a stock rom, I unrooted my phone successfully. Since this I have no connection at all. No 2g, no 3g. I've done some research on the Internet but couldn't find a proper answer. The phone shows the imei number but it doesn't match with the number under the battery. What should I do?

As per the faqs and guides restore your backed up EFS folder .
Not read the basics and no EFS backup then its a paid for service repair.
jje
I have no efs back up. I rooted my other phone million times but I've never backed it up. So jje you basically mean there is no exact solution for the issue. I need to send my phone to the service?
If you flashed a custom rom it may have a EFS backup look for EFSbackup.tar on your phone .
Looked for it but there is nothing. I've sent a PM one of the XDA users who is an expert with IMEI. I'm waiting for his answer. If he can't fix it I'll visit a Samsung repair centre. The phone is now out of warranty, isn't it? How much they are gonna charge me roughly?
did you try to flash an emg2 or emg4 baseband? some have reported that this can restore network connection

You are amazing mate. Your suggestion fixed the problem. I now have 2G, 3G connection on my phone. Thank you so much.
make sure that going forward if you flash any other baseband or rom that includes a baseband as all stock roms do and also some custom roms as well, that you flash one that is newer than what you have now. the older basebands can no longer read the efs folder because beginning with emg4 the efs folder is modified so older radios will not work properly. back up your efs folder because it may get corrupted. if that happens than only a backup can restore your network connection, this time you got lucky it was not corrupted yet. the format changed but the info was intact. please read the stickies all the answers are there.

Dear Ashraf sharif,
My sgs3 gt i9300 currently has baseband version I9300 DDEMG2 and bulid number JZ054K.I9300XXEMG5.
I had flashed resurrection remix rom and i got my IMEI changed and baseband version unknown then i restored everything back with a lot of help form rootsu,now my issues are:-
which all baseband i can flash or which roms are suited for this ie what should i look for in a rom while flashing as far as baseband and not ****ing up my imei is concerned?
and does that means in addition to flashing a custom rom i need to flash a baseband also as you mentioned that few custom roms have baseband ie all doesn't have basebands???
thanks in advance.......
I am no expert on this issue as I have not experienced it myself. With that being said , it is my understanding that once a g series modem or baseband is used reverting to an older baseband will result in no network. Read the thread in general called " attention 19300xxemg4 changes efs folder". some firmwares do not touch the baseband only affecting system+ kernel+ recovery.
Since you are on mg2 baseband it is probably safest for you to stick with it because it works . If you do decide to change it make sure you flash a baseband that is either the same or newer. Also make sure csc code is correct for your region.
Make several backups of your efs and save to external sd and computer and flashdrive. Read the stickies .
wait and see before flashing . Read reviews for newly released firmwares. This is how I avoided this relatively new issue with efs imei . I simply read the thread "attention 1900xxemg4 changes efs folder.
Well, after installing the unstable JB 4.3 Vodafone Germany leak from http://forum.xda-developers.com/showthread.php?t=1835931, I've loaded my stock ROM I9300XXEMF6_I9300OJVEMF1_I9300XXEMA5 (4.1.2, Egypt) to PDA on Odin and flashed it. However the variants of Modem and CSC did not change from existing ROM with a change in IMEI.
How can I restore stock values for IMEI, Modem and CSC while I don't have Odin files for Phone (Modem) and CSC.
I9300XXEMF6
I9300OJVEMF1
I9300XXEMA5
Thanks!
Go read the stickies in general, in particular efs 'know this stuff'.
Basically you can't go back to anything earlier than EMGX baseband, flash anything later and your imei should be found again. Or you can restore the efs backup you made before flashing the 4.3

So you suggest what to flash to restore the IMEI since I didn't backup EFS? Please refer any guide
Installed back leaked 4.3 ROM and could successfully restore the stock IMEI. I used kTool to backup efs as efs.bin. So I have to wait an official release for my country to be able to flash it without losing IMEI anymore.
the same here

iam facing the same problem
i could not find any way to solve this
i really can keep the rom 4.3 installed
but the phone is very slow
when i press any key to turn on display (not the phone) it can take from 3 to 6 seconeds to open
hope someone help
The stock kernel is very poor, try the liteGX kernel instead.
Same here.....but I've installed the IRISH 4.3 ......there's a silly wake up lag, too .....could I change the CSC to Egypt without root..... wishing that the Egyptian update roll out soooooooooooooooon.
Hello All.
I have a Samsung Galaxy S3 international (GT-I9300 - OS 4.0.4 - I9300DXLE8 baseband) I applied a ROM update (4.2.1) and lost signal. I then flashed again using various ROMS but nothing. I did some research about the EFS folder and using the XXEMG4 modem binary to get the IMEI number back from the generic one but now I cannot connect to any of the mobile carriers that are found. I have to admit, before I discovered the XXEMG4 issue (from a thread here) I did (mistakenly) look in to the EFS folder and I confess I most likely have messed that up and that may be the reason I cannot get a signal any further even though I can get the correct IMEI?
Is there anything I can do which would not involve sending the phone to Samsung? Flashing the stock ROM did not fix it and now, I have found, regardless of what ROM I flash, I must also flash the XXEMG4 modem as well otherwise I just get a generic IMEI number. I blame myself and my own stupidity for not reading more about the EFS system first (and not making a backup either) so I just wanted clarification that there is nothing more I can do.
To summarise:
Updated ROM and lost IMEI (generic)
Did not back up EFS folder
Flashed various ROMS - no service & generic IMEI
Flashed ROM with XXEMG4 modem
Phone IMEI is correct but still no service - emergency calls only
Ariza patch did nothing, factory reset does nothing, stock ROM does nothing.
Many thanks for your time.
Install the patched mg4 modem and all should be fixed

Start from beginning flash leaked firmware via odin from sammobile
Then root by cfroot
Install recovery and then flash custom recovery..
Also if u do have a backup of stock with working imei then u cn restore that if u dnt want to do the odin procedure..
Thanks for the replies but I seem to have fixed it.
I restored back to stock ROM, restored EFS Backup using KTools and restarted the phone and all is well.
I am now backing the phone up completely using EFS Pro.
Many thanks.
If you've corrupted files in the efs folder then no, there is nothing you can do yourself. The repair should not be too expensive as no hardware needed replacing.
Edit. You wrote 'didn't backup efs', but now say you've solved it by restoring your backup -which is the whole point of taking a backup before you flash anything.

greetings, ive read several threads about the IMEI and efs thing but unfortunately i havent found a solution for my problem yet.
I´ve lost my IMEI because i deleted my efs folder from the root folder of my phone (galaxy s3) and i had no backup. Someone restored the IMEI with Zbox or Octopusbox (not sure which one it was) and everything worked fine. So i made an efs backup and flashed Cyanogenmod, but after flashing the Rom my IMEI was lost again (0049...) and the phone couldnt find a network. Restoring the efs backup did not work and so i had to go back to stock and let the guy restore the IMEI again.
And here comes my question: I am currently on stock rom with rooted kernel (havent flashed any rom since the second restore because i dont want to risk losing the IMEI again) and i really like to change the Rom because you know stock rom is kinda bad. Does anyone have a clue what i need to look out for or why my IMEI gets corrupted on flashing another Rom?
What version of firmware did it come back from the repair with?
Usually a poor repair will install an older firmware, with efs v1, as boxes won't work on v2. Trying to update to a newer firmware, v2, will corrupt the imei.

the firmware wasnt changed at all, it was UGMK6 stock with CF-rooted Kernel. the IMEI got restored via samsung tool on my pc and it got connected to the box via UsbOverEthernet client. The console only showed like:
-checking root access
-writing IMEI to phone
-patching modem
-ok
is there a way to check if i have efs v1 or v2?
