The problem is it's better to have the branded firmware on it, but really we need to see if the issue exists on their firmware too. If there is no MG4 or newer from them, you may have to wait for their update :(

It's CWM flashable. If you don't know what this means, read General > Sticky roll-up > Understanding the basics before rooting.
[Galaxy S III General] boomboomer:
If the problem is still present with the stock rom then you have a hardware fault and need a service centre. Do not mess with the efs folder, there is nothing you can do.
[Galaxy S III General] spykedsystem:
Something is fishy...I just flashed the Hong Kong firmware from october, and it works, so the problem is only with MG basebands/roms, everything else works, maybe this efs format change is actually a bug somehow and not intended for all the future firmware..I will have to wait and see if the future releases work

Hello archi, i come from original XXEMG4 rom and then ultimarom XXEMG4 based without problem. If i try to install your archidroid 2.1.7 (latest) i have no network (no imei, version of baseband unknown), even using your emergency.zip after installed the rom. Do you know how can i solve this?

PS: if i install back ultimarom or stock samsung i've no problem...

Thanks m8. Greets
[Galaxy S III General] spykedsystem:
Today I have found something interesting (to me) at least. Here's a recap of my problem: Whenever I tried using a rom after july MG4 or later, I would get emergency calls and fake imei, but I was able to revert to older roms without problems or changing basebands, i just couldn't use any newer firmware because it did not change my efs format. That being said, flashing a newer baseband on older 4.1.2 roms like XXEMB5 would give me emergency calls, even though somewhere in here it says that the modem should work with older efs format. It didn't in my case.

What I have done today is flash XXEMG4 (again emergency calls and fake imei), the flash the boefla kernel and XXEMB6 baseband...and voila signal was on XXEMG4 with EMB6 baseband and no efs change. So I think it has been said before but I guess it is a kernel issue. Hope it makes sense.

Tried with Siyah kernel,also works

Bro . If i don't have a v1 efs backup . Buy i install a mg4 modem wich reads my imei and stuff .. would i be able to use another not mg4 modem again ?
[Galaxy S III General] boomboomer:
Read the OP again, carefully.
[Galaxy S III General] earthman5678:
I upgraded to ZSEMI1 and the modem stays the same XXLLA. I don't know if the problem is specific to XXMG4. Perhaps something to do with the recent regional lock for Europe and America.

Hi guys i would need some advice. Im planning on selling my S3 i9300. I have unrooted & restored my regions firmware.Unfortunately my efs has been messed up since i came from a rom who's using mg4. I have both old and new efs backup. I need some advice on what should i do.Basically i want my phone to receive the usual sammy update,is it still possible? I would really appreciate your advices.

Edit:I think i dont have any other choice but to wait for the latest sammy update and see or download other regions firmware like UK :(
[Galaxy S III General] JJEgan:
You require the latest update that covers your exact phone as originally sold to be 100% sure of OTA or Kies updates .

[Galaxy S III General] lantonis:
Hello. I got the same issue here but i think a little different if i read correctly.

I had custom roms for more than a year and i decided to go back to stock to days ago. I downloaded the one from sammobile and flashed it. I dont remember if the network worked because i had it like that for like 12 hours only and dont remember if i made or received any phonecall, but i think it was ok. Anw. after the 12 hours i tried to root it aswell to get the super su etc. Then as i was debugging my app i noticed that the application was very buggy and decided to reflash again the stock just in case it caused the problem for the app. After that reflash to stock i cant connect to a network, i have full signal but, lost my imei(it says 0049...0000 something). I never backed up efs but thankfully i had one in my phone from August so that should do it i think. I tried restoring it with the efs.img and efs.tar.gz and still no luck.

So my question is its the modem's fault? If i use that emergency.zip ill be ok for my country or carrier or i dont really know very well how this goes or what depends on.

this is the one i downloaded for my country and this one messed me up and changed my imei.

Thank you for the reply. I think this post made it clear. Inbetween i tried also an avatar rom and noticed that i still didnt have an imei. But that rom came out on june. When my phone was working i had newer roms on so they added my phone an efs v2. And i tried using efsv1 roms to try and fix this. Ill try a newer rom and hopefully am ok. Thanks for the info.

help with emergency zip

HI there

I

I'm hoping you can help me with a "not registered on network" problem after flashing on my s3 GT1300 !

The phone works perfectly except no carrier netwrk. so no callls or text or mobile data.

The IMEI number is now showing as 004999010640000 / 01

I think that your emergency zip may hold the answer to my problems. I am about to reflash to the stock rom XXEMG4 and then use your emergency zip. I would be really grateful if you could explain how I flash it to my device after installing the stock rom. Using Odin?If so , is there a 'best version of Odin? or is it something I have to do using root access?

I thank you in advance for your help and apologize if I seem inexperienced in this field. I was just trying to gain gamepad control thru USB on my s3 phone, and was hoping that upgrading to 4.2.2 would be the solution! Unfortunatley it left me without phonecalls or texts!

hope you can help!

kind regards

[Galaxy S III General] ErnestoD:
Hi Archi.

Im using a 4.1.2 rom with ariza patch (v0.2). I started using it after installing my first jellybean rom

I made U a question today in the forum on your new 4.3 leaked rom about the EFS.

I iinstalled MG4 baseband and then rom but with no luck. I always get the No conection to Network

I have a backup of my EFS folder and now Im confused.

Si is it possible that S3´s on jelly bean depending on ariza couldnt get 4.3 becouse of the EFS v2 ???

I really dont know what to think. becouse Ive flashed your rom and others CM10.2 with no problem at all

So I Im stocked on 4.1.2 Sammy´s rom??

Thanks man
[Galaxy S III General] JustArchi:
Hey.

If your efs is corrupted and can't convert to EFS V2 then you're screwed, no Android 4.3 for you.
[Galaxy S III General] ErnestoD:
Ok. But how to know if it is corrupt. Right now everything is working for me.

Or do I have to convert to v2

Thanks man
[Galaxy S III General] JustArchi:
Flash my Deodexed ROM http://xdaforums.com/showthread.php?t=2509764 and attached optional modem. All "at once", doesn't matter which first.

If you get signal after reboot conversion and efs is fine, you're running efs v2.

If you get no signal then you're screwed, efs conversion failed.
[Galaxy S III General] ErnestoD:
Oh man don't tell me this

I did it yesterday and get the Not connection to network message

So I'm screwed

I will have to stay in cm 10.2

Thanks for the help archi

[Galaxy S III General] vinhtq79:
Did you guys try to flash XXEMG4 stock ROM and then flash 4.3 stock ROM???? It is the right way, I think...:gif

If you flashed XXEMG4 stock ROM or modem (EFS V2) and then flashed older 4.1.2 stock ROM or modem (EFS V1), your imei and network would be damaged because of the EFS version change. 4.3 ROMs only compatible with flashing from EFS V2.

If you were on EFS v2 and then you flashed 4.3, and you lost your imei and network, maybe because your efs was corrupted like some guys mentioned. In this case, I think you should try to reflash XXEMG4 stock ROM and then flash 4.3 stock ROM.

It's my collected experience, hop it helps....
[Galaxy S III General] jmweb:
Please JustArchi, could you upload your emergency zip. Actual Dropbox link doesn't work.
[Galaxy S III General] maxniper:
Thank you,

Haven´t tried on that way, i have only flashed XXEMG4 and no network, i will try like you said.
[Galaxy S III General] Nickthegr8:
did it work maxniper?

so update us on the outcome pls
[Galaxy S III General] maxniper:
it din't work and the strange thing is that inside EFS folder i have one other EFS folder.
[Galaxy S III General] vinhtq79:
I am said to hear that, so may be your EFS is corrupted. The question is, does the other EFS folder has the same content as EFS mother folder? If they are the same, I think you should replace current EFS mother folder by the other EFS folder you have inside and see if it works.

Looking forward to hearing from you!

Good luck! :good:

i have tried almost everything, deleting, creating, efs pro and i have hallways the same thing, on modem before XXEMG4 i have imei but on modem XXEMG4 and newer that use EFS_V2 i have imei 004999010640000

I'm on XXEMC2 modem right now running PA 3.99, can someone please advise what the correct procedure would be to safely update to stock 4.3 for BTU when it's released? I am wary from posts here that people are having issues with IMEI/EFS after flashing.

I'm planning to revert to back to stock Sammy and then perhaps implement dual boot set up with PA.

Is it best to revert to 4.1.2, back up EFS and then upgrade?
[Galaxy S III General] keneth_c:
grrr....

just happened to come across this today...

i updated to 4.3 stock (ODIN) yesterday for i9300 and 4.3 was buggy....

downgraded to 4.1.2 stock using Odin again...

and my phone then could not register to the mobile network (my telecom)....

had i known this i wouldnt have bothered...

my phone is now at the service center (official Samsung) for rewriting IMEI...

cost me US$35 approx...

my phone is not under warranty anymore...

its more than a year old...

apart from that...

the service center did not ask me any questions about me rooting the phone or anything...

i guess they have no clue...

so i guess i didn't leave any traces...

either ways i will be getting my phone back in 2-3 working days....

The service center will flash 4.1.2 stock rom with CSC (LYS or AFR or XSG)...

Now my question(s):

Could i have saved my phone if I went back to 4.3 and then backed up my EFS...

then got back again on 4.1.2 and restored the EFS?

also...once I do get my phone back...

how do i make a backup of EFS partition for keeps?
[Galaxy S III General] Mord0rr:
Hi.

I have root acess so i copy all past to external SD.

Also, and

this is the correct option, i enter recovery using Touch Wix, and in backup´s options, there is the option to backup only EFS

....

Yesterday i also give up 4.3, and when did install Omega 4.2.2., no connection...

Install this moden and voila....but im not very happy with it....

Hope i did help...:highfive:
[Galaxy S III General] keneth_c:
Question

So there is a backup option for backing up EFS in which recovery? CWM or the recovery you get after rooting?

I'm guessing you are now stuck on 4.3 ?? If you do have a backup of EFS while you were on 4.1.2 / 4.2.2 ... why can't you go back to Omega 4.2.2 or stock 4.1.2 and restore your EFS? hmmm...
[Galaxy S III General] _Negan_:
Same problem here. If i install for example wanamlite based on official 4.3 android i've no problems at all but i can't install for example slim bean 4.3 because of i've no network access and "unknown" written under settings --> baseband. Anyone know the reason of this? I mean:

Full Wipe --> install official 4.3 android based rom --> OK

Full wipe --> install slim bean android 4.3 ---> no network access and unknown baseband

Thanks to all.

[Galaxy S III General] Mord0rr:
PROBLEM:

Reading my posts above i thought i had made a backup with recovery Touchwiz of EFS.....

Yesterday after tried Ireland Rom 4.3 and reinstall Omega 4.2.2. i had no connection. Install Moden I9300XXEMG4 and regain conection...

Today i found out that Touchwiz didn`t make any backup of early tried install 4.3...

In fact,

i tried today make backup of EFS only with TW and when i go to Clockword to check for backup there is nothing

!!!

Resuming:

Before i make mistake of install 4.3 my backup of EFS didn`t go well!

I can make backup o actually EFS....so im probably stuck with baseband V2.....so how can i return and install V1?

The only backup i have before make install of leaked 4.3, was to copy all past EFS to external SD....

Suggestions?

What`s worrong with Touchwiz backups?

Can i install new rom with different Moden, without be afraid of make erros? (XXEMG4)
[Galaxy S III General] Mord0rr:
Weird....:confused:

Because in TW THERE is the option to make up backup only of EFS...

maybe you mean it doesn`t work

I did read this tread....but gonna give another try later at home....:eek:

[Galaxy S III General] jforme:
It is always good to have a backup of efs, I took a backup using PhilzRecovery on to my externalSD card, it will save some trouble for you, if any thing goes awry during ROM flashing. Also, note that people are not having IMEI/EFS problem when they flash stock 4.3, but trouble starts when you downgrade to 4.1.X, later as stock ROMs MG4 and after use EFS v2 so, older modems from the older stock ROMs are not able read it.

I have not flashed 4.3 yet, but wanted to make sure I don't end up in trouble like other people. So have been reading up on this for more than a week. It took me almost like 2 days and hundreds post reads before I got the hang of this problem.

I suggest you do the same before you actually flash 4.3.

Help with EFS backup

Hey guys

I got my phone back from the service center & they have rewritten the IMEI back onto the phone. They have also flash the official sammy 4.1.2 for my region (CSC = XSG).

This time around... i made sure I took the backup of EFS partition (yayyy!) using kTool by Hellcat.

I now have 2 files... img & tar.

I opened the tar file & these are my findings

"imei" folder > filename "mps_code" file doesn't have my IMEI number. Instead it shows "XSG" which is my CSC.

also

"FactoryApp" file > filename "serial_no" shows "00000000000" (which def is not my serial #)

Is this normal?

Otherwise when I go to Settings > About phone ... my serial # and IMEI number is showing properly.

Please advise.

P.S: Both my laptops (Windows XP & Windows 8) now do not detect my phone when connected via USB wire. USB debugging is on & drivers are also installed. Not sure if this has happened after re-writing the IMEI. Hence I am forced to use Airdroid right now. But i'm thinking of going back to the service center & telling them about the USB issue i'm not facing.
[Galaxy S III General] JJEgan:
USB debugging... WHY??????

Suggest you remove and reinstall USB drivers and factory reset phone .

imei" folder > filename "mps_code" file doesn't have my IMEI number. Instead it shows "XSG" which is my CSC.

Correct /

"FactoryApp" file > filename "serial_no" shows "00000000000" (which def is not my serial #)

Is this normal?

YES
[Galaxy S III General] keneth_c:
Thanks for the confirmation :)

With regards to the above...

I factory reset from phone (not using recovery) and then flashed again with stock 4.1.2 for my region XSG using ODIN ...

(Baseband version: XXEMA5 & Build # XXEMF6)

also rooted using CF_auto_root...

used triangle away...

did factory reset using recovery...

and then let the phone boot up...

(i didn't take the EFS backup again.... i don't think I need to do it everytime right? My previous backup (for same stock version 4.1.2) is saved on my phone, laptop, Dropbox & Box accounts.... lol !!!)

On my laptops...

I uninstalled Samsung drivers... rebooted... installed Samsung USB driver for Mobile phone v1.4.6.... rebooted again...

connected the phone to the laptop (with USB debugging OFF)....

nothing happened...

then while the phone was connected....I turned USB DEBUGGING ON...

again nothing.

Have tried the same with Samsung drivers v1.5.25 as well. No luck.

Even Kies is not recognizing my phone...

have tried the latest version of Kies as well as older version (v2.3.2).

I tried again today and its recognizing it as a device but is not recongnizing it as i9300... but says 7 CDC's with a yellow triangle (inspite of having Samsung USB drivers installed).

So now this is the only issue i'm facing after losing my IMEI... and getting it re-written by the authorized service center....

HELP!!
[Galaxy S III General] keneth_c:
The issue is only when Downgrading from 4.3 to 4.1.2.

That's when u would need the XXMG4=+ modem. And that's when the emergency.zip file comes into play to fix the issue.

U flash the zip file using Odin after u have flash with 4.1.2 ROM + rooted + triangle away.

Then flash emergency.zip using recovery.
