I have a Samsung Galaxy S3 AT&T (I747) phone, when I tried to install android 4.3 Stock ROM which I downloaded from a 3rd party website I Baseband, IMEI and lot others became UNKNOWN . After a lot of googling i found out it could be because of the efs folder. But I didn't have any back up of it. I downgraded my phone back to 4.1.1 successfully, but still the issue persists. I could not find any backed up efs folders online and none of my friends are using a s3 AT&T model.
Please suggest what else can I do? or if someone can help me out, provide me with a efs backup for efs professional.
Thank you in advance.
How did you downgrade to 4.1.1? I didn't think that was possible once the phone was running a 4.3 or higher bootloader.

I found flashable files for both firmwares which made the downgrade possible.
Are you sure the bootloader was downgraded to 4.1.1? Running a 4.1.1 rom on a 4.3 bootloader can cause the issue you are experiencing.

Yes, My mistake the bootloader and modem were struck at 4.3 even after the firmware downgraded to 4.1.1. So I again updated it to 4.3 and restored a qcn file i found online and it resolved my issue.
Glad you got it resolved. If you run into the same problem when flashing recent custom ROMs, you may have to upgrade the bootloader and modem to KK.

Hello there,
I live in India and my Note 2 is a Poland made and running with 4.1.2 stock ROM non rooted. But the device status was shown 'modified'. Due to that (i think) i was not able to get any updates. So i decided to download and flash 4.3 ROM via odin. I did exactly and flashing was success. But after that i was not able to connect to my mobile network. It shows the coverage, base-band version, operators around me, IMEI...etc. But failed to register on network. Sadly i found that my IMEI was changed. Then i searched in xda and found out few modem patches. To flash them i rooted device and installed recovery. Then flashed DMG1_MODEM and modem_XXDME4 but nothing happened. Phone is still not registering to network.
What to do ?
I assumed that your device history was imei null or efs corruptted which has been fixed under 4.1.2 version.by upgrading the modem it will surelly broke your efs again.use special box to repair the network, nothing else you can do.
you have to flash the factory-image via odin (i think this would be the poland one in your case). you will get this on sammobile.com. with this it recreates your efs including your imei. (had this problem also)
after this you can try flashing a different rom, but don't forget to backup the efs

Is it safe to downgrade from 4.3 to 4.1 just by flashing factory images via odin ?
If you have flashed the latest bootloader MK4,its not possible to downgrade to 4.1 as of now...

So using the phone like a tablet without GSM is the future for me ?
Just purchased an unlock code from Telus but it does not work. I know some posts mentioned it only works with a stock dialer app.
Is there anything else I can try before attempting that?
If not, what stock rom can I even use? And is there a guide available?
Sorry if this has been asked before. I had trouble finding any answers.
Thank you.
Just flash your stock firmware with Odin.
The boot loader on your phone will determine which firmware to load on your phone.
If you have the 4.3 bootloader, don't flash 4.1.1 or 4.1.2.
Flashed stock rom, booted with sim inserted, and entered the unlock code when asked. It worked! Thanks for the reassurance, I was hesitant.
Here are some links I came across that might help others.

You can also get firmware from http://sammobile.com/firmwares. Their downloads are much faster than samsung-updates IME.
Easiest root method ever! - Towelroot (shouldn't trip the warranty bit either)
If I'm not mistaken, the recoveries having problems reading the sd card is due to your hardware version. I believe they found a solution in the Sprint forums, but I haven't had a chance to read up on it yet. If its something I can do I'll probably try to fix the T-Mobile and AT&T recoveries. I may be mistaken on some of that, but its how I understood it after a quick search the other day.
Need help for flashing stock rom
Hi,
Can you please clarify few things for me?
I have an ATT Galaxy S3 (SGH-i747).
I am running CM11 Android 4.4.4 Baseband I747UCDMG2.
I need to go back to stock to SIM unlock the phone.
Latest ATT stock rom is 4.1.1 with I747UCDLK3.
Will flashing to stock ATT ROM brick the phone?
What is the best way to go back to stock ROM?
Thanks,

Thanks for quick reply.
Bootloader on mine is I747UCDMG2 which is from 4.1.2. Hence I should be ok to go to stock 4.1.1 ROM.
I am reading few other posts before making the move.
Flashing the USA version of the s3 (i747) with any i747 firmware from sammobile in Odin can brick your phone us you have a 4.3 bootloader or higher.
Since you are on 4.1.2 bootloader, flash the stock ATT 4.1.1 ROM from sammobile.com using Odin. After flashing, do a full wipe in recovery. Boot the phone and use the free method to permanently sim unlock your phone.
After unlocking your phone, you can run OTA updates to get to the latest stock ROM, bootloader, and modem.
Just confirmed bootloader and baseband are I747UCDMG2.
I will update here how everthing goes.
PS: I DON'T want to go to I747UCUEMJB bootloader after unlock. That will mean, I will not be able to downgrade in future. AFAIK, I747UCUEMJB bootloader is also locked.

correct in that you will not be able to downgrade (serious risk of bricking your device).
bootloader is not locked on the S3 AFAIK. (bricked my s3 on mj2 trying to 'unlock' an already unlocked bootloader.).

I agree that the bootloader is unlocked.
I think at times people are calling the newer bootloaders locked because they are unable to downgrade them. Whereas we are calling them unlocked because we can still root them and flash custom/unsigned ROMs.
ATT has been locking the bootloader on other phones such as the Note 3, HTC One XL, and the Moto G so I'm not surprised that owners think their bootloader is locked.

Thanks all for the assurance and support.
I was able to ODIN to stock ROM and SIM unlock the phone.
Background: My ATT S3 i747 was running CM11 Android 4.4.4. Baseband and Bootloader was I747UCDMG2.
Steps:
1. Flashed rooted stock ROM (root66_ATT_I747UCDLK3.7z) using odin from http://forum.xda-developers.com/showthread.php?t=1739426
Followed the steps in OP.
After flash ODIN showed PASS and phone rebooted. It was stuck in Samsung logo. I booted into recovery. Performed a wipe cache and factory restore.
Phone rebooted successfully after that.
2. Inserted non-ATT SIM and it asked for the unlock code. I had obtained the code from ATT before. Used the code and phone was unlocked.
The same code did not work while I was running CM11.
NOTE: When running stock ROM you can follow steps in below threads if direct unlock did not work for you.

Hey guys,
I got a I747 I want to give to my mother as a gift.
I downgraded 4.1.2 to 4.1.1 and ran the secret menu unlock to unlock the sim card, that worked perfectly.
Now I want to update this out of 4.1.1 to 4.4.2 but I cannot find a stock firmware to run on odin anywhere.
Do I need to go to 4.3 first? Is there a stock firmware for that?
SamMobile stops at 4.1.2... OTA obviously doesn't work.
How Can I get this done..

I have a Motorola Atrix from Bell. I flashed it with stock ATT firmware and received OTA updates from ATT over wi-fi.
Since you have the i747, start with stock pre-rooted ATT 4.1.1. This will flash the stock recovery, radio, and bootloader. Run triangle away, flash a stock unrooted ATT stock 4.1.1 ROM, and take the OTA updates.

You can flash i747m firmware on your phone but DO NOT flash the radios or bootloader from an i747m to an i747 and vice versa. Bricking is a really possibility if you do that.
Do you have a custom recovery? If you do, you will need to install a stock recovery.
Try resetting the phone (wiping cache, data) in recovery or through the ROM itself.

Alright, I have the stock recovery. How do I not flash the radio and boatloads when using the firmware from sammobile?
You cant. You cannot flash another devices firmware. Odin wont let it happen and if it did youd end up hard bricked due to mixed firmware. For example your sbl1, modemst and param partitions (plus others) would be i747 and youd be flashing sbl2, sbl3, rpm, etc from an I747M.
The only thing you could use are the system partition and kernel, nothing else. There are two ways to accomplish this, one is to build a rom from the firmware and flash that. The other is to flash with mobile odin, but that requires root and youd still have to be very careful.
Another priblem I see you encountering is you cannot run 4.4.2 without 4.3 or newer firmware. It will not boot otherwise.
You need to go to the General section and follow one of enewman17's tutorials to get to either 4.3 or 4.4.2. Personally, I dont see any other way you will be able to accomplish it.

Alright, based on Doc holiday, and others they say It cannot be done and from my experience I beleive them.
Thank you,
It's very difficult to do this when others are giving bad advice.
So for the record, cannot flash i747m firmware to i747.
Thanks!
The annoying part here is I can do it with my m7, I just flashed the Dev edition onto my Bell m7 with no problems.
All devices are different in many ways. What is perfectly safe to do with one brand or model can brick another.
And I wouldnt call it "bad" advice... I've seen audit13 and others helping lots of folks with very good advice. We all make mistakes and we all have more we can learn about these devices. No one knows everything about this stuff and shouldnt let that prevent them from trying to help.
Those who are trying to help are doing so with the best of intentions and tell people what they think could be the best way to solve a given problem. In cases like this one, its easy to see how anyone would think its ok to flash different firmware between similar models based on being able to do so on other devices they are familiar with. (If I had gone into those forums I wouldve been telling people the opposite and ended up being wrong there.)
All I can say is chalk it up as a new lesson on a different device, and I hope you still appreciate that someone was trying to help.
@audit13 I hope none of this discourages you from helping. Ive seen plenty of threads where your advice was sound and appreciated, and I am glad you have been around to help so many people out!
Now, back on the problem at hand... if you want to be running the latest 4.4.2 kk, you will have the option to use the OS (/system and kernel) from either the I747 or I747M firmware. But first you must fully update to a minimum of the 4.3 MJB firmware for the I747. Once you have this running for your base firmware/bootloader, you can then run the Bell or AT&T (4.3 or 4.4.2) system. (I hope this is making sense!)
So first, update the full 4.3, MJB, firmware via Odin. (Theres a thread in General with the file, ill post the link in a min).
If you want to update to 4.4.2 firmware, you can then follow enewman17's tutorial to do so via OTA.
You can then either stay with that, or use Mobile Odin to flash ONLY the system and kernel from the Bell firmware.
Let me know if any of that needs better clarification! Also let us know what your ultimate goal is. From the options you have, where do you want to end up?

I REALLY apologize in advance if this has been covered, but I can't find anything else on point, even in the suggested links above.

I recently bought a used Galaxy S3 to use as an MP3 player that worked great until I upgraded from 4.1 to 4.3. This borked my device sound (no speakers, no headphones, video playback would skip and freeze with no audio) except for Bluetooth, which worked fine and allowed for videos to work as well.
I upgraded to Cyanogenmod 12.1 which didn't fix the sound, and actually broke the Bluetooth.
I figured I would follow the tutorials for low sound issues and through ES File Explorer I discovered that I had no sound folder at “/device/etc/sound”. There is a file there called audio_policy.conf and audio_effects.conf in the etc folder itself. Not sure if that is even relevant.
I read a post on another forum with an S4 user having the same issue, and he found a solution here to install the files "NON-HLOS.bin modem.bin sbl2.mbn tz.mbn aboot.mbn rpm.mbn sbl3.mbn" which fixed all of his sound issues. Perhaps there is an equivalent for the S3.
Unless I can find a solution my next course of action is going to be to try downgrading back to a stock 4.1, but I would ultimately like to get 12.1 running.
Any help is appreciated!
The phone was running stock 4.3 (including bootloader, recovery, and modem) when the sound issue arose?
Once on stock a 4.3 bootloader, you cannot downgrade to a fully stock 4.1 ROM.
Crap - I thought I had read that. I figured there was always a way.
Is there a resource anywhere for specific drivers, such as audio drivers? This has to be driver related, unless upgrading systems somehow broke my hardware. I find that hard to believe.
Would a driver issue in 4.3 persist with successive system roms?
Thanks!

Which bootloader and modem are currently on the phone? This is important to know before flashing anything else as the bootloader and will determine what can and cannot be flashed.

Hi Audit -
Not sure about the bootloader.
Bootloader version is: I747UCUFNE4
Modem version: modem_CWM_I747UCUEMJB
Modem version is reporting unknown, but I flashed modem_CWM_I747UCUEMJB yesterday. I am not using any sim card in this, so I read that perhaps that is why it reports unknown.

Hi alphaja,
Do you mean this thread?
It says I need to have a certain firmware to use this...my phone says "firmware forbidden" under samsung phone app. Not sure why it won't report my firmware version...
I always recommend matching the bootloader and modem as an incomaptible modem/bootloader combination can hard brick the phone.
Since the phone has an ne4 bootloader, I recommend flashing an ne4 modem to see if the audio problem is resolved. Do NOT flash anything that attempts to downgrade the phone's ne4 bootloader.

Great idea - I am downloading it now.
It is really impossible to downgrade bootloaders and then to android 4.1? Or just difficult?
Where can I find "full" rom that would work with this bootloader and potentially have all the uncorrupted files that I need?
It is Impossible to downgrade from 4.3 to an older ROM. You may be able to flash an older 4.4.2 bootloader over a newer 4.4.2 bootloader but I'm not sure why anyone would want to do that and take a chance on bricking the phone.
Once you are on NE4 bootloader and modem with TWRP, you could flash ne4 via TWRP.

Hello felipe here and I am in dire need of help. I currently got my hands on a Samsung note 2 (I317M) which I wanted to unlock as it was with Rogers and I wanted it to work with Mobilicity (Both carriers from Canada) but in doing so I downgraded to Android 4.1.1 and wish to to get 4.4 KitKat as it has a variety of apps that I used before.
I want to software update my phone but I have modified it and I have thought about getting another firmware and was wondering if the phone would still be unlocked. I am not sure. (Came here because I know XDA is filled with people that know more than I do about Android rooting and such)
Any advice would be immensely appreciated. Sorry I f I sounded too naive also
Just flash the latest 4.4.2 stock rom from sammobile.com. Once the phone is network unlocked, it will remain unlocked after flashing custom and stock ROMs.
I recommend creating a back up of the EFS folder in case the folder become corrupt during a flash process.
