Hello
My friend bought GS3 months ago in Arabic country with ICS 4.0.4 installed. When I saw the box, I found that the GS3 is a grey market product. It has Region Lock label written in Russian language on the box and the ROM is pre-rooted CWM Custom ROM
Now, Kies dose not upgrade this version and he wishes to have Arabic stock ROM 4.3 if possible. What are the safest steps to do?
- If I download and flash Arabic stock ROM, will I loose modem connectivity?
- Do I need to backup and restore EFS data if I flash stock ROM?
- Do I need root to restore EFS data/modem driver after flashing STOCK ROM?
- Should I flash custom ROM instead of Stock ROM?
I want a safe way, I don't wish to cause network/EFS loss to the device?
I read a lot but came to no conclusion.. please help

Kies shld have an emergency firmware feature. Try using it.
1. U will not. Just dun downgrade
2. If u aren't gg back to 4.1.2, dun bother. But recommended.
3. Yes.
4. Ur choice. If u wan bugless rom, go for stock rom. Many also say stock is one of the best.

If u are rly just tat scared to lose ur imei. Go kies and do the firmware recovery. U will get stock rom automatically.

Depends on the phone history on what will happen on upgrade to 4.3, sim lock may return or imei lost due to patched efs folder. No way to know until you get flash, so backup efs now.
4.1.2 EMG4 is when efs format changed, anything before this shouldn't cause too many issues.

That's what I am worried about. To loose IMEI or get the region lock back. The phone model is GT-I9300RWDEUR. Can I find stock rom for it with no region lock?

The model is GT-I9300RWDEUR European SIM model
The ICS 4.0.0 is causing to many problems and device hangs all the time
Actually it is from Greece. I was confused with the language (Ελβετία= Swiss)

So if I upgrade to 4.1.2 before EMG4 , I won't have EFS/IMEI problem?
All I have to do to flash midle east ROM and then to find the Modem driver and install it through odin?

Hi. I have 2 australian galaxy s3. First one is on 4.1.2 TDUELL2 and the second one is on 4.0.4 TDUBLH1. I want to root both of them. The first one after getting updated to 4.1.2 wifi stopped working but i found a fix installing the wifi folder from 4.1.1 version. To that I need root though. So any help on how am I gonna root them both? Cause I couldn't sort it out my self.

What model number are the phones I9300 / I9305?
they are i9300t
I managed to root both of them. I know have a major problem. 1 of them had a problem with wifi. It couldnt connect. I read about a solution by copying the wifi folder from version 4.1.1. Tried that. It worked for once but after reboot it stopped. And now I can't even turn on the wifi. It gets stuck on Turning on... Do i have to reflash the rom again and if so how will i do that? It was stock rom on stock kernel. Only rooted. gt i9300t moder and build DUELL2.
Also can i flash a rom with different build over that? For example XXEMC2 that i have on my Greek galaxy s3?
I9300T rooting is the same as I9300 rooting, follow the guides of CF-Root 6.4 or CF-Autoroot. (I got a T model myself)
You can flash any I9300 rom also on the T model, therefore root is not 100% necessary. Full wipes are recommended for flashing different versions though.

just saw it .
For wifi, try a stock ROM (flash it new incl. wipes etc.), or try a different kernel, whereas the stock kernel should always work.

you can find (unrooted) stock roms for instance on sammobile.com or (rooted) stock roms here on XDA in the General section.
Easiest way to flash them is via Mobile Odin (gives you the option to keep root) or Odin (you will loose root but you can flash CF afterwards manually).
And yes you can flash any build that is made for the I9300/I9300T.
The only difference between both models is the frequency of the baseband (the T model is more optimized for 850mhz) whereas you even can use modems of the I9300 on the I9300T.

What do you mean by modems? Soz if I sound noob but I am new to Galasy s3. My previous android was ideos x5 and i had a miui rom on it.
The phone will be used in greece. Do you suggest me flashing the XXEMC2 rom that i have on my Greek S3 atm? Is there any chance of bricking it if i flash that rom on it?

There is a difference between the ROM's firmware (basically your OS, e.g. XXEMC2) and the modem (basically the part which gives you the connection to the next mobile tower and is managing the frequencies, e.g. DUELL2).
It does not matter that much what ROM firmware you use as they are nearly identical in each country (here and there dif. apps due to providers) but more that you use a modem that delivers in the country you are in. Hence, I would first try the modems of your region (you can find a list of all modems in the General section's modem collection).
Regarding the risk of bricking: there is always a risk, no one can guarantee you anything , whereas if you follow the guides you should be fine.

Ok. So the CSC numbers that are different on lets say the DUELL2 and the XXEMC2 are not something to bother me right? I just download the XXEMC2 rom and flash it on the DUELL2 S3 and then I just will root it. right? Will the phone become i9300 after that procedure? or stay i9300t? So I know which file i should use to root it.
Soz for too many questions but the phone is not mine and I need to be sure for the procedure.

The firmware code (XXEMC2) should not be of concern.
The modem code (DUELL2) should be of concern IF you experience bad performance in the region you are. If so, flash a different modem and try it.
The phone will be an I9300T whereas in the menus it might tell you I9300, anyway there is no difference in the files to use.
For rooting, follow the guide, you can use CF-Root 6.4 (if you want a custom recovery) or CF-Autoroot (if you want to use stock recovery).

Thanks a lot mate. This helped a lot. I decided to go with the 4.1.1 version of its current region. Later if we see that it doesnt perform well here in greece we will flash the xxemc2 rom.
Ok i downloaded the rom from sammobile and the file name is this I9300TDUDLK1_I9300ZZZLK1_VAU.zip but i get an error message that says cannot open. file unknown or damaged :/ Why is that? Is this file meant to be named as md5?

To flash a rom via odin you need the md5 file, correct. Hence unzip or if you cannot maybe the download is corrupt?

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.

MG4 is perfectly safe, it is a BTU firmware intended for the UK, it works extremely well and it is the users of this forum that don't know what they are doing that make it unsafe... It's as simple as that

It have to be BTU? remember the BTU MG4 changes your imei for ever...... so its a risk to flash it. thats why i did not flash the MG4 and flash a earlier version not BTU XXEME2, its sooo nice..
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.
No.

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

Hi, SignetSphere

by highlighting i want to emphasise these points (do let me know have i understood correctly)
1) i'm on stock XXEMG5 and yours is MH1 which means yours is ahead of mine and how's it better or it's just region specific???
2)you are on MG2 baseband/modem does that means you also have to be restricted to MG2 baseband/modem only when flashing roms????
thanks in advance.....

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
I haved rooted stock rom. But i just unrooted and put same unrooted stock rom with mobile odin. Tried factory restart and cache clear.

First of all try unbackup EFS(in G-play there are some tools,i prefer K-Tool).If there is more issues try custom ROM with patched modem and patched kernel. If you prefer read this: post 1441 : http://forum.xda-developers.com/showthread.php?p=48578725#post48578725

Thanks, but this patch I must use every time I update phone. I haved rooted phone, but I want normal, unrooted phone to use updates.
Does anybody alse now how to fix? Maybe modem or update?
Does flashing new version of stock rom will help? Is efs backup just for IMEI problems or can help with s/n 0000?
Any help?
why don't you try to just update your firmware to 4.3 (choose 4.3 stock roms) to quickly fix those issues.

oh sorry. i edited my first post which is this:
"""
First you need to find the right rom for you
go to sammobile.com (register first in able for you to download stock roms) click firmwares, choose your phone gt19300 and your country. It will display the list of stock roms. choose the rom that you like and then check the modem version the last three figures should be MG4 (for 4.1.2)
if you already have the rom then follow this guide on how to flash with odin:

and i changed it to "nevermind" because i don't know how to delete messages and you already know how to do it because you already flashing custom roms before.

You should've done some reading first:banghead:
I am afraid to ask if you have Efs backup?
Flash 4.3 again and pray . If it recovers(imei) then downgrade to 4.1.2 and when you choose firmware be sure that it's not below mg4 modem.
Backup Efs after flashing 4.3 if you get back your Imei.
