I haven't found a custom ROM I've liked, so I want to go back to the stock Samsung ROM for my i9300 (UK).
Which should I download and flash to my phone? I9300XXEMG4?
I would, it's best BTU firmware to date

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

Holy crap, I9300XXEMG4_I9300OXAEMG4_BTU.zip is 850 MB :| Talk about bloated
They're all that big. Fyi mg4 alters efs. Flash that and you cant use any other baseband

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....

"JUST... DONT!"
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.

Just instale a safe firmware. not MG4 AND MF6.... i am on XXEME2 ITS THE BEST.
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

READ the faqs and guides before flashing .
Is your IMEI correct of not restore your backed up EFS folder .
No EFS backup as per the instructions then you require a service centre repair .
Read the faqs and guides critical to understand post one and two BEFORE flashing
before sending to service center you can try installing a stock rom from sammobile via odin. this sometimes recovers the imei and network connection. you need to install a stock rom and reset your flash counter anyway if you want to keep your warranty
Make sure to flash a recent rom that uses mg2 or mg4 baseband.

What modem did you install? if you installed XXEMG4 it would have formatted your 'efs'
Check your IMEI by dialing *#06#
for more info check this link
The modem does not format or erase the efs folder. It alters the format so older modems can't use it. That is why if there is no efs backup prior to using mg4 or mg2 modem. It is impossible to revert to older modem

Its actually the rom not the modem and yes, ultima is based on a version of the rom that alters efs.

Not sure what you're asking.
Read general > Sticky roll-up thread > "IMEI / EFS - Know this stuff"
Everything I have read, but if you want to return a Nandroid backup, if you will?
It's nowhere
if your nandroid backup does not use an mg2 or mg4 modem than it will not restore your network. if you want to fix your phone go to sammobile.com choose any rom that uses mg2 or mg4 modem. flash it with odin. if that doesn't work take it to a service center
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

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.
Sent from my GT-I9300 using xda app-developers app
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.

Hi everyone,
Before I flash a custom rom, I would like to know the answer to some questions I have.
This is the situation: I have an international galaxy s3, I9300XXELLA, with stock rom and android 4.1.2 and I'm interested in flashing the latest cyanogenmod 11 milestone.
I would make a nandroid backup first, so will I be able to just flash my nandroid of version 4.1.2 and downgrade from android version 4.4.2 to 4.1.2?
Also, if I make a nandroid of cyanogenmod 11, will I be able to just switch between the two roms like it's nothing?
Sorry if my questions are noob, but I've tried to downgrade before and I got stuck in a bootloop, I don't want to get this problem again..
And yes, I've searched google.
Any help is greatly appreciated!

Okay I've read the topic about efs and IMEI, but I'm not sure if I understand everything correctly
Please correct me if I'm wrong and feel free to give extra information, this is what I think I understand:
Once I flash a rom that was made after the efs format change, I can't go back to a previous version of my modem on that rom.
If I make an efs backup with CWM, I CAN restore it only if I go back to my stock android 4.1.2 (?)
But do I need to restore my efs backup on my new rom? I thought that wasn't necessary..
And another thing, I already succesfully installed a PA version AFTER the format change (I think android 4.3), and was able to go back to stock 4.1.2.. Got a bootloop but was able to fix that in recovery. The stock rom still works, never had problems with the modem what so ever, the only thing I did was restore my nandroid backup of 4.1.2, fixed the bootloop in recovery, and got a working, factory resetted 4.1.2...
So if I flash CM11, will I be able to go back to stock if I use a nandroid (and efs) backup?
Can someone give me a step by step tutorial please? (I just want to know what I have to do)

Thanks, so I don't have to worry about the modems or the efs? Even though my build version is from before MG2?
So for switching to CM and back to stock, I should do:
- make a titanium backup of apps
- make nandroid backup of 4.1.2
- factory reset/wipe cache/wipe dalvik cache
- flash CM
- factory reset/wipe cache/wipe dalvik cache
- (test CM rom, put on some apps ect.)
- make nandroid backup of 4.4.2
- factory reset/wipe cache/wipe dalvik cache
- flash nandroid of 4.1.2
- factory reset/wipe cache/wipe dalvik cache
- reboot
- restore apps with titanium backup
Will this work?
Thanks everyone, any help is welcome

Yes you do have to worry about efs if you do not backup your efs you may have problems maybe not today or in a week or month but if you ever corrupt your efs by flashing roms and you do not have a backup you will have big problems!....First rule when flashing roms backup efs!
Second rule save a backup not on your phone .

Hi,
I've encountered a problem today. By mistake i have restarted my phone after the wipe, and soft bricked my phone. Then I tried to flash to stock with odin and after a few tries managed to do it But the problem is, after the flash i've got a "selected network unavailable" notification. Tried many things, different stock firmwares, reinstalled many times, but to no luck. After that i've installed aospa and tried to restore my efs backup, but that didn't help either. My imei is intact and in download mode my model is shown too.. What can I try doing to make it work? I can provide any information you ask.. My model is I9300 International. Baseband version in "about phone" tab is: I9300XXEMG4, the stock rom i've installed is as shown in *#1234#: PDA: I9300XXEMG4 CSC: I9300OXXEMG3 MODEM: I9300XXEMG4
Go read the sticky thread on efs in general forum.
If your efs backup was made when your firmware was older than EMG4 then you need to downgrade to the old firmware before you restore it, as efs format changed at EMG4.
Both the imei and serial numbers are required to obtain network.

So I think you should flash a patched modem matches with your firmware

You have just saved my life. Indeed flashing patched modem matching my firmware (UGNA8) after flashing Boeffla-Kernel on stock helped regain my network Connection. May it be a remainder of how easily you can mess up your phone
So officially, problem solved.
