Before someone tells me, YES I know this is a common problem and YES I know there are lots of thread that talk about this particular subject.
But I think I'm having a different problem.
I had a I9300 unbranded that, for some reason, didn't wanted to update through Kies or OTA. But It could make calls and send txt msgs.
I decided to update it manually using ODIN to the latest official firmware for my phone (XEF - France). I downloaded it from Sammobile. Everything went perfect. Then I wiped everything to just to be safe.
Everything works great. Wifi, Apps, everything. Except making calls or sending txt msgs. It says "not registered on network".
My IMEI is still the same as before (the efs didn't get corrupted I guess).
Anyway, I have a backup from every partition. So I can get back to the previous state. But I want to fix this problem! Does anyone knows what's wrong?
I use to have this:
PDA: I9300XXBLH3
MODEM: I9300XXLH1
CSC: I9300XEFBLH2
Product Code: XEF
Country: France
And I flashed this:
PDA: I9300XXEMG4
MODEM: I9300XXEMG4
CSC: I9300XEFEMG2
Product Code: XEF
Country: France
Did I do something wrong?
You're not having a different problem at all.
You've installed an MG4 modem

Would you mind telling me what's exactly the problem I'm having?
I have another i9300 with the same modem and that one works fine!
Your original modem was version one but when you installed the mg4 modem and it changes your EFS to version two.
All sorts of problems can happen now.
Try installing patched Mg4 modem which is found somewhere on here

Oh...f*ck!
I used the firmware that was supposed for my phone. Nothing else. Everything stock. I've downloaded it from Sammobile. I can't believe it!
My IME is OK. It's the same I used to have before (when it worked). Are you sure that my EFS is wrong now?
Can't I flash another firmware? I still have my EFS backup.
Which one should I've had flashed of these?
sammobile -> /firmwares/1/?model=GT-I9300&pcode=XEF#firmware
(Sorry I'm not allowed to post links yet)
If you backed up your EFS before the upgrade , you have two choices.
Go back to the original firmware and restore your EFS from backup or
Install patched mg4 modem found here on forums.
Sometimes the modem is not compatible with your region.
You can flash any of the newer modems available here as well.
You just can't install the older modems as your EFS has been changed to EFS version 2

I've been reading this: http://forum.xda-developers.com/showthread.php?t=2377731
But I still don't undestand something. My IMEI is showing correctly. Shouldn't the phone work anyway regardless of the Modem version?
The problem on the modem version is that once is changed, you can't revert back unless you have an EFS backup. But that doesn't explain why my phone is not working. Am I right? I mean, it should work! I have another i9300 with the same modem and it works...
Are you sure this is my problem? I don't see the logic behind your sugestion.
Flashing a full stock rom, EMG4, including the modem shouldn't break anything. You say your phone had issues before you flashed, did it have any unlock or serial (ariza) patches applied?
If so then they won't work on efs v2 and you'll need to apply the patched modem, or flash an earlier rom (from before EMG4) then restore your efs backup.

My phone was rooted and it didn't update though official methods (I don't know why!). I wanted to leave it to stock. That's why I flashed the stock rom. Thanks god I did my backup. But I want to keep this version, It is official and it's the latest one. It should work!
I've bought the phone on Amazon and it came already rooted to my surprise. I just wanted to return it to stock, Should I start worring?
I actually backed up everything except USER DATA partition. So I can still take a look at the system partition I used to have (I guess...).
My previous issues where related to my phone not wanting to update. But the network connectivity was ok.
If I flashed a new stock rom... can I still have remanents from the previous rom? I also wiped everything. Does that make any sense? (sorry I'm kind of new in all this).
PD: I'm getting scared!!! :crying:
Best go read the efs 'know this stuff' thread in general forum, stickies for more information and links to help.

The stick says "Also it would seem, Phones that had this patch ON EFS v1 ROMS will break their IMEI if they upgrade to EFS v2 ROMS."
My IMEI is ok. So I guess I didn't have ariza patch installed. That's a relief.
Anyway... I think I'll wait a bit. Maybe it'll fix itself ( I'm just lying to myself here haha).
Ok more question RickEphraims. Why exactly I need a "patched" modem? I don't want to revert to EFS v1. I just want my phone to work properly. Wouldn't it the same to flash stock MG4 modem again?
I'm no expert but the patched MG4 modem has worked for lots of people. It's still an MG4 modem.

Ok. Thanks.
I will try to flash this version:
And then restore the EFS partition.
Or should I do it the other way (efs first and then flash).
I want to stay official. This is not a phone I will be using so I don't want to leave a root in place or anything like that.
Any advice on this regard?
Flash original firmware and restore EFS.
That should put it back to stock

Easiest to try and check COULD BE:
1. Goto setting-> More Networks-> Mobile networks -> Network operators
2. Search for network service provider and select it !
Ok. So I flashed the previous official stock firmware (efs v1). As expected, the IMEI wasn't ok. So I restored my EFS v1 backup. IMEI was ok again. But I still get "no network".
I'm now going back to the original firmware (4.0.4) to see if it starts working again.
The phone is unbranded and apparently from France (XEF). Can I flash any other firmware? France is not my country although firmware 4.0.4 worked alright.
Also, Is there a way to know if Ariza patch was installed before I got the phone?
Check the phone serial number matches the one under the battery. Ariza patch fixes serial number problem on efs v1 only, it didn't fix imei issues.
If it's an i9300 then any firmware will work, you say 'apparently' from France, you should know this information -it is suspicious that do not.

News news. I flashed back the original firmware 4.0.4. It didn't work.
To my surprise, the serial number is 00000. THAT is my problem. And I now undestand why it was rooted from the start, probably it had some sort of patch to make it work (like ariza).
Now I'm not sure what to do. Send it to repair (I WILL be expensive in my country) or try the zuluman patched modem. But I guess flashing the patched modem is postponing the inevitable...
What a luck...
There was a post in general forum where a guy edited a file in efs folder to restore serial, you can try that or update to EMG4 rom and apply the patched modem.
You will probably find patched modems get released for newer roms, don't stay on older firmware -they cause SDS.

I had to Google "BTU". I believe it's a UK firmware variant.
The other UK firmware variants seem to be: "BTC, CPW, H3G, O2I, O2U, ORA, OXA*, TMU, TSC, VIR, VOD, XEU"
What's the difference between them all, and is BTU the one I want?
BTU is unbranded like from carphone warehouse as opposed to branded that you get direct from the carrier
please try to remember; questions go in the q&a section. General isn't for questions

I don't know what that means.
If you dont know what that means, you definitely shouldn't be flashing things!
I'm not sure how basic I need to be so i'll be as basic as I can.
The s3 has an efs partition. This is a partition on your internal memory that stores your imei number among other things
The imei number is mucho important. Without a working imei number, your phone cannot operate on a mobile network. In otherwords, your phone is nothing more than a miniature wifi tablet.
Every official rom comes with a baseband. This is also known as modem or radio. This is software and its responsible for connecting your phone's telephony Services via the radio hardware to the network.
Many rooted users change their baseband in the hope that they get better signal / battery life
Now here is the problem. The latest official 4.1.2 changes the format of the efs. The mg4 baseband "updates" efs. The baseband works fine and can read the imei and the phone can continue to operate on the network. However this new efs format is not backwards compatible. This means any older baseband (packaged with any rom other than mg4) cannot read imei, meaning you cannot connect to the network. At the moment, only the mg4 baseband can read the updates efs so once you flash this rom (and baseband) it is not possible to use any other baseband. If you flash any rom older than mg4, it will only connect if you then put the mg4 baseband back on.... unless you backed up efs before flashing mg4... in otherwords, once flashed mg4, unless you backed up efs, you can never go backwards with the baseband. Or rom....

Or make sure to read a guide about flashing roms before you flash any rom. Especially about backing up your efs folder. A lot of the custom roms have options for doing that or do that automatically so chances are you may already have an efs backup, but better not risk it.
Well he could flash that rom but he has to back up his old efs first for getting safe.
But I do not think he is able to do that due to he is unknowing.

Dude learn reading.
Flashing the BTU EMG4 Firmware will change your efs for ever, so if there is any bug or part in this firmware you do not like, the way for backflash will be complicated.
The old modems are not able to run with the new efs, so U have to flash the new modem on the older firmware.
Or you flash back your original efs back.
But this could be very dangerous because people are scared to do that.

Hey Guys,
So I had my usual SIM card working as usual on G4 stock 4.1.2 firmware. I later on flashed CM10.2 20130814 Nightly build after which my phone was stuck on Emergency Calls only. I flashed three different stock 4.1.2 official firmwares after that but nothing seemed to fix it. They recognised my SIM and carrier though they weren't able to make calls and whenever I tried to it gave me the error message "Not registered on Network".
It is a fully unlocked i9300. I would really like your guys help on this.
Questions go in the Q&A forum, report your post and ask for it to be moved.
Does your IMEI number in phone match the one under the battery?
Did you make a backup of your efs folder like all the guides recommend?
If your IMEI has changed and you don't have a backup then flashing the latest full stock via odin on your pc sometimes enables the partition to be read again.

If not then you need a repair.
I am currently back to flashing another stock firmware so didn't check. If it doesn't match then what sort of repair would it need?

Problem: /efs partition format changed
The latest 4.1.2 UK (XXEMG4) and India (XXEMG5) ROM releases (Which come with MG4 and MG2 basebands respectively), actually change the format of efs.
If you have flashed a, XXEMG4/5 ROM at any point, you are now in a situation whereby only an MG4/2 baseband can read the IMEI in /efs. The new efs format is not backwards compatible with older basebands. Probably, all new basebands will be compatible so in time this issue should diminish I expect.
If you have ever flashed XXEMG4/5 ROM, to keep your IMEI working, you must:
Stay with the basebands MG4/2. You may flash other ROMs but must return to the MG4/2 baseband.
Restore your efs backup (taken before XXEMG4/5 ROM install) to use older basebands.
Please note, it is flashing the ROM that alters efs format, not the basebands themselves. You can flash the MG4 or 2 baseband safely on their own and return to an older baseband without issue.
You can download an MG2/4 baseband package HERE
Aroma installer, choose between MG2 and MG4 basebands
Basebands alone do not alter efs format
Backs up EFS in an uncompressed format (Use Root Explorer to restore)
Does NOT include RIL, works on AOSP and Sammy

NO it didn't work as i installed the latest firmware through odin, and then get OTA as well but it didnt solve the issue, then i installed the MK6 BTU firmware but it didnt work as well.
tired of installing the ROM's and Patches but non of them worked, is there any posibility to get it in working condition or should i use it as IPOD???
Take it to a repair centre and pay them to recode it, make sure it works on 4.3 firmware before you pay them.
Patches are a work around for modified efs problems, a corrupt or wiped efs can only be solved by professional repair.
I have an i9300 with a blank efs folder. The phone corrupted and was stuck in a boot loop. This happened when battery run out while file sharing was in progress via bluetooth to another android samsung. I flashed it with 4.22 android jelly bean immediately XXUFME3 but it remained stuck on boot loop, I never backedup efs file. Later found the original ROM although it comes up as custom rom, which is i9300XXEMB5_i9300OXAEMB5 but still no luck as it stuck in boot loop. My sister has the same identical phone both were purchased together in Dubai. I did factory reset etc, no luck still in boot loop.
I later gave it to a mobile shop who flashed it with a rom for free, didn't charge me because it came up as imei null/null and baseband unknown. The phone now boots and has Build number of IMM76D.I9300BUALE6 and is german language I believe. I had read some threads by now and I immediately rooted the phone and backed it up, but my efs folder is blank.
Last night I flashed the phone 2 times with i9300xxemb5 rom and rooted it and it still boot looped even factory reset or cache delete don't solve boot loop, Then I restored the working rom of build i9300BUALE6 from CWM and powered phone on and got a baseband of i9300XXEMB5 and Build of i9300BUALE6 also got an imei of 004999xxxxx0000/01 and the phone found the network and my efs folder which had been blank all this time was full of files. In my haste I realized the sim was not plugged in and removed battery, when I restarted with sim, baseband was gone and imei was null/null. I repeated my steps in hopes I could get this fluke opportunity but nothing yet. Was this a miracles I didn't seize by not backing up the efs folder?
My sister's phone is an identical model bought together with mine is,
AP:i9300xxemb5
CP:i9300xxemb5
CSC:i9300oxaemb5
So my question is I need the original stock rom for my sisters phone that won't get stuck in a boot loop on my phone
My phone is now
AP:i9300buale6
CP:unknown
CSC:i9300vfgale6
Also can this be fixed by backing up my sister's efs folder or backing up her phone and flashing it on my phone. I can't get warranty for this phone now since it has binary counter of 12, don't have proof of purchase and also I am not in Dubai but in Africa. What Rom file should I try to flash. Also because this is a custom rom I am not getting samsung serial port in device manager can't use NV writer. Any help is appreciated.
If you don't have an efs backup then you need a service centre, you cannot repair it. Trying to use another phone's efs folder won't work and is illegal in many countries.
Read the sticky on efs:
http://forum.xda-developers.com/showthread.php?t=2393289
If its a custom rom their is a very small chance that it included backup pf EFS .
Look for EFS tar file on phone .
I say slim chance and judged by the OP probably no chance .
004999xxxxx0000/0 that's just the generic non working IMEI .

Sorry to hijack this thread but I dropped my S3 i9300 on water and have the imei null /null and baseband unknown problem, therefore SIM cards are not recognized. Do you think my problem can be solved by doing something without taking it to samsung service? Meanwhile I ordered a SIM /SD tray replacement but my bet is it won't solve the problem.
Thank you.

hi from what you explained it seems that right now your phone has no baseband. One thing you can do to possibly recover your imei and network settings is to flash a stock rom that uses mg4 or mg2 baseband. use a rom from sammobile and flash with odin make sure you use a rom with an mg2 or mg4 baseband. good luck

Thanks a lot for the reply.
A user from another thread suggested to install the Perseus Kernel first. Do you think that would help?

A custom kernel has no connection with the lost of IMEI or it's a solution for the recovery of an IMEI. So no, no custom kernels will help you with your problem.
Either try ashraf's suggestion or ultimately bring it to a Samsung service center for repair.

Thanks for the input, M8. So you think I could try to flash a stock rom that uses mg4 or mg2 baseband?

You can try but i doubt that it'll restore your IMEI. If that doesn't work then you have no choice other than to bring it to Samsung for repair.

I don't know about perseus kernel but I don't think it will help. your imei and efs foder was intact before flashing4.2.2. I understand that the problem began before flashing 4,2,2. but if you ever had a rom that used an mg4 or mg2 modem and then used an older modem your phone would lose its network connection and would probably display a generic imei number. if it says null usually that means it is corrupted or no modem is installed . either way if you send to service center you need to flash a stock rom and reset your flash counter . since some people have recovered their efs and imei by flashing newer modems or firm wares that use them why not try it before sending phone to service center

Thanks but you didn't read my first post. I did not flash any rom (or even root) before the problem, which started from dropping the phone on water...so I have no warranty left This means I can take the phone anyway I want (custom kernel, rooted) to samsung service cause they will charge me anywat.
But I think I will try to flash a rom like the other user sayd because I flashed the Perseus Kernel and the phone is now unstable and reboots randonly...
Cheers
my mistake that post was for the op of this thread
I don't care anymore that my original answer was
deemed not acceptable enough and warranted a second opinion. I am once and for all, going to put this nonsense to bed.
If you lost your imei because you submerged your phone in water it is a hardware issue. It is INCONCEIVABLE that flashing a rom, kernel or baseband will restore the imei. A SOFTWARE solution will NOT repair DAMAGED HARDWARE. This is obvious!
If your Blu ray player cannot read disks because the disk tray fell off, upgrading the laser driver wont help. This is exactly the same.
Depending which hardware failed, replacing the tray may help although given the symptoms, it seems much more likely that your radio stack is damaged. Take it somewhere to get it repaired and stop wasting time pretending software will fix your issue. It's IMPOSSIBLE

2)you are on MG2 baseband/modem does that means you also have to be restricted to MG2 baseband/modem only when flashing roms????

I see you're still struggling to understand this.
2) If the ROM is MG (M = 2013, G = July) or Newer, the ROM changes EFS format. This means if you flash one of these ROMs without backing up your EFS, you are restricted to using an MG modem or newer as only Modems from July 2013 can read new EFS format. I'm really not sure how I can make this any simpler to understand.
However, if you flash the modem separately from the ROM, EFS is not changed. So for example, if you are on ME7 ROM, you can flash MG2 modem without affecting EFS.
I hope this is clear now.

Dear rootSU,
you've been very patient with me and i really appreciate your efforts at making me understand and i've understood a lot because of you only,but what puzzles me is that
1)this restriction is for those who've not backed up EFS whereas in my case i had in the very beginning only made an EFS backup.
2)and if i flash ME7 ROM then since am coming from MG5 to ME7 my imei would again be corrupt and i'll have to flash MG2 baseband...right??even if i have an EFS backup(EFS PRO won't restore my imei in this case despite a backup)?
thanks in advance
Yesterday I updated my i9300 to android 4.3
Baseband version I9300BUUGMJ3
Build number JSS15J.I9300XXUGMJ9
..and since then I haven't had any reception. My imei number, serial number, and everything else is same and still there, but I just can't get it to get reception again... When I go to my Mobile Networks, it says registered on network, but again, no reception. Then I tried installing the modem BUUGMJ3 with odin which didn't work. What can help? Stock firmware? Please help.
Thanks in advance.
currently experiencing the same issue mate. I can't seem to find a workaround/solution for this -__-
Is that base band supposed to work in your country? Find an modem later than EMGx, without a RIL, for your country and install that to test.

I've probably made a big mistake there, no it's meant for mine country, it's for the county near mine, Croatia, but I read somewhere that this doesn't matter.. :/
And by 'later than EMGx' I'm not sure what you mean, but I've flashed EMG4 modem which didn't seem to work.
Found something about flashing a previous modem and restoring your EFS folder, but I do not have my EFS folder backed up - I forgot to.
A few days ago I paid about $30 for a repair on my phone, I don't really want to send it off for repairs again, I really wonder if there is an fix to this
Follow the guides in general forum, stickies on how to flash back to 4.1.2 stock rom. Make sure it's at least EMG4 base band.

Yeah, about that...
first of all, sorry for bugging you so much..
but I downloaded the right stock firmware for my country, I9300XXEMG4_I9300BHTEMH1_I9300XXEMG4, but after I flash it via odin when the phone turns on it gets stuck in a loop showing the Samsung logo repeatedly...
Edit:
Okay, I managed to install the stock firmware 4.1.2 but it still is showing 'Emergency calls only', the modem is xxemg4...

how about your IMEI/Serial numbers? are they still the same before you downgrade and flashed the XEMG4 modem? mine are the same with SN/IMEI so I guess that's why it worked. I just took the risk cause I was really pissed experiencing the lag and the battery drain in 4.3.
Do factory reset from settings option in touch wiz, make sure the imei and serial number match the label under your battery.
If still no good then try another SIM in your phone, final steps would be restore efs backup then repair centre.

Well it's all the same as it used to be. Could it be that the modem I had before EMG4 changed the format of my efs folder?

Did a factory reset, imei, s/n same.
Android 4.1.2 EMG4 modem still no reception.
It seems that MGX modem has change ur IMEI from /efs1 to /efs2. MGX modem seems to support only 4.3 roms (due to some security issue).
It is not recommended,but u could flash an older rom with modem (get from www.sammobile.com) then restore an efs backup (if u did some) from /efs2 to /efs1

Ariza patch only works on older modems (efs v1 modems). So, that wont help.
You said you flashed the zuluman modems but.... did you flash the patched kernels too? You need the patched kernels for the patched modems to work. I don't know why, but that's what zuluman says (according to him, the kernel has a modem signature check and it wont work if the modem was modified).

Here are all the patched modems and kernels made by zuluman.
https://drive.google.com/folderview...&usp=sharing&tid=0B6MIUd7HJudAbU5YaGkzOUowMG8
In my opinion you should flash the latest official firmware and download the appropiate modem and kernel from that google drive.
You can download the latest official firmware from the general section of this forum.
Good luck.
Remember to always have an efs backup!
Great thanks!

Flashing the Modem + Kernal after rooting the Phone works for me. I have flashed it using CWM.
Thanks once again.
the same problem with signal
hello,
i've the same problems with my s3. i flashed it OTA to Android 4.3
After this i had no signal. ...
When i found this thread i was so happy. BUT!!!
i downloaded all the modem and kernel files from the google drive and wanted to flash them (Patched_XXUGMK6_xxx.zip) with cwm recovery (latest version).
whenever i want to do this, i get the following message and the update aborts: "E:Can't copy META-INF/com/google/android/update-binary"
what can i do? Can i flash them with odin, too? Or does anybody have another idea?
here are some Infos about my Phone:
Android-Version: 4.3
Baseband: I9300XXUGMK6
Kernel: 3.0.31-2191747

hmm...
can nobody help me? ...
sorry for spamming, but i've got a problem without a phone
greetz,
Carpe.
You said your imei & serial is ok but you cannot register to network. Have you paid your bills?
But if it's corrupted serial number.
Try this guide.
thx for your answer.
Payed my bills? ... uuuuuups!
back to topic: i've flashed my phone back to 4.1.2 for the moment. Network seems to work. ... i'll try some things and give a feedback here. ...
You have to flash an Android 4.3 modem for it to work I think but as your on 4.1.2 now I guess it doesn't matter anymore

Hi everyone, my question is, can I update i9300 from 4.1.2 (XXELLA) to any 4.3 version or does it have to be for specific country?
I am curently running XXELLA that is for Poland, I was on XXEMC2 that is for Slovenia, and I am from Croatia, also to mention that original is XXEMC2 from my phone.
Also, is it safe for me to download 4.1.2 BTU XXEMG4 (UK) and flash over my current XXELLA, can i brick my efs? (I think it is an additional option to upgrade from btu version to 4.3).
Will i brick my EFS by updating to official stock 4.3 via Odin? I wan't to get to 4.3 version that supports OTA to 4.3 version MK6 (I heard it has many fixes), but I am scared to lose my network signal.
To sum up, what firmware do i need to get the MK6 update, is there any except BTU, and is it safe to update via Odin so my EFS won't brick.
Thanks.
You need to understand the basics before you do anything, sticky guides in general forum will guide you.
If you aren't confident then wait a week or two until MK6 is released in your country.

It's a good option to wait, it isn't even official for download to flash via Odin, I am just curious over what will or will not happen, so I'm just searching for some direct answers, when I read all those stickies and threads I got very confused.
Can i just ask, will anything happen with network signal or efs if i flash XXEMG4 4.1.2 BTU or MJ9 BTU over my XXELLA with Odin? Just to know..

I'm from Croatia too, and i have MJ9 BTU since day one and my phone is functioning perfectly, so no need to worry about network signal etc.
My recommendation is that you flash a MJ9 ROM with some custom kernel wich will remove the well known wake-up lag and battery drain that MJ9 has. Or you can just wait official OTA update for Croatia if you want. Personally, I moved away from official ROM 10 days after I got my S3. But as the boomboomer said before: read all the stickies to be 100% sure what are you doing
Hi, Before flashing anything or attempting to do anything make sure you read this and back up your EFS, If your already know about the risks then carry on but this is very helpfull. Thanks

Ok, I'll try to flash BTU MJ9 over current XXELLA and will see what happens, I already have backed up my efs and also nand backup, but i think i can lose my efs/no network because my IMEI was repaired with z3x box, I heard that if it is repaired with z3x i cannot upgrade nor downgrade anymore, will see what happens, if anything goes wrong i have z3x so no need to worry i think, i'll also try to flash mg4 modem or patch it with Ariza if i will lose my signal..
There is a thread with patched modems for those that previously used ariza patch, which should enable you to connect to your network.

I found only for 4.0 and 4.1.2 but not for 4.3 modems, and they are not patched, for patched i read that ariza patches modem but that it doesn't work with 4.3 android.
Can You please provide me the link to thread of patched modems?
Thanks!
Edit: I saw some patched modems for 4.3 but there is not MJ9 for i9300, also i tried extracting the modem.bin and patch it with zuluman patch and install through odin (put it under Phone section) but it fails, it says in the log something with bootloader, please provide me the patched M9 modem.
Edit2: Succesfully flashed patched MJ9, now IMEI is null/null, i'm getting really tired of this, going to take it to local servicer to update it for me, i think repairing imei with z3x box got it all messed up. And also finnaly i tried flashing the original modem back that gave me my IMEI back and than patch with ARIZA, nope, imei was 0049 etc.
