I have Pac Rom Android 5.1.1 installed on my rooted sg3 and I need to do a carrier unlock. I contacted ATT to get the unlock code and the code they provided didn't work. Now I want to downgrade to Android 4.1 and try the UMTS menu trick as described here http://forum.xda-developers.com/showthread.php?t=2176719
I have tried Odin many times (with many versions, different computers, USB cables, etc) and every time Odin fails to flash Android 4.1. with a Fail AUTH error. I have used Odin successfully in the past many times with this phone but am unable to get it to work this time around.
Does anyone know how to downgrade the sg3 from 5.1.1 to 4.1? Or even better does anyone how to carrier unlock the sg3 when it has 5.1.1 installed on it?
Thanks!
Odin is probably failing because you have a 4.3 or 4.4.2 bootloader on your phone. I recommend you not flash anymore ROMs using Odin as repeat attempts to flash the 4.1.1 ROM via Odin may hard brick the phone.
Once a phone is running and 4.3 or 4.4.2 bootloader, you cannot use the free/hidden menu method to unlock the phone.
You cannot use a custom ROM to enter an unlock code. You'll have to go back to a stock ROM, enter the code, and return to a custom ROM.
Thanks for the reply. Do you know how I can go back to stock 4.1.1 without using Odin?
You need the 4.1.1 bootloader in order to use the free method. Once a phone is on 4.3 bootloader or higher, you can't go back to 4.1.1. Don't try because attempts to do so could brick the phone.
A stock 4.1.1 rom on a 4.3 bootloader will not work.
So you're saying once the sg3 is on a version above 4.3 there is no way to go back to 4.1.1?

Once it is on the 4.3 or higher bootloader, there is no going back to an older bootloader and it is the older 4.1.1 bootloader and stock 4.1.1 ROM that is required to unlock using the free method.
Since you have the code, you can flash a stock ROM from recovery.

Thanks. What do you mean by free method?
Also you suggesting if I put the 4.1.1 stock rom .zip on my sg3 I can flash it via CWM just like I would the latest 5.1.1 Pac Rom release?
The free method is the method you linked in your original post. This is the only free method available and it requires a 4.1.1 bootloader that your phone doesn't have. Installing 4.1.1 via cwm is not going to help you unlock it.
Since you have the code, you can flash a stock ROM from recovery.

How would I do this? Do I just flash 4.1.1 from cwm?
Flashing 4.1.1 onto your phone will not allow you to enter the code.
Before flashing anything, you need to verify the bootloader that is running on your phone. Until you do that, I would not flash any bootloaders or modems. An incompatible modem/bootloader combination can also brick your phone.
Sorry, one last question.
You'll have to go back to a stock ROM, enter the code, and return to a custom ROM.

How can I go back to the stock rom?
You can flash a stock rom from the general thread using twrp or cwm.
Awesome, thanks again. I was worried about going that route since I'm on 5.1.1 but I'll give it a shot

When you pick a stock ROM, make sure you pick one with the same bootloader and modem that are currently on your device. You probably have either the NE4 or NJ1 bootloader and modem pair. You DO NOT have a 5.1.1 bootloader and modem, they do not exist for the SGS3. Check your versions from a Terminal Emulator app or check them with the Phone Info - Samsung - app from the PlayStore.
Both NE4 and NJ1 stock ROMs are available in the forum. enewman17 posted them form image dumps, they have been used successfully by many.
The Terminal Emulator commands are:
Code:
getprop ro.bootloader
getprop | grep version.baseband
Thanks, I did this and both the bootloader and modem ended with NJ1 so I downloaded UCUFNJ1_Rooted.zip from enewman17's thread using CWM 6.0.4. The flash was successful but now the phone is frozen at the AT&T logo when I turn it on.
Any thoughts as to why its stuck booting up?

More than once I have seen reports of this happening when going from a 5.x.x ROM back to 4.4.x. The most common solution has been to include formating the internal sdcard before flashing the stock ROM.
If I flash the sd card as well I will lose the UCUFNJ1_Rooted.zip file. So in that case should I use adb via CWM to flash it?

Put the zip file on the external sdcard and then flash it with your recovery.
I actually didn't have an external SD card. I wound up taking it to the ATT store that had an ATT repair shop inside it and they reset it back to stock 4.4 for me and now everything works great! After unlocking the carrier on the phone I did have to manually enter the t-mobile APN to get the data connection working but that was simple (the info is listed on t-mobile's site)

I got Rogers Samsung Galaxy S3 SGH-I747M.
On it is installed Cyanogenmod 11 20140531 nighty d2lte with Android 4.4.2.
I found this firmware : Canada (Rogers) (Black Edition) , 2012 May , I747MVLALE8
PDA: I747MVLALH1 CSC: I747MOYBALH1 MODEM: I747MVLLH1
and program Odin3-v3.09.
The phone is locked to Rogers.
The color is white.
My goal is to unlock SIM lock.
1. Can I put firmware in zip format on SD card and just restore from SD card in recovery mode?
2. If no, what steps to do to reach the goal to get 4.1.1 stock ROM (rogers? telus? att?) to unlock SIM lock?
3. Maybe I have to do it from laptop with Odin or from the phone with Odin?

Thank you for reply!
Than more I know than more questions:
a) The ROM I found here is stock ROM 4.3 I can revert to -? -> by meanhacker -> Rogers (RWC) MK5 , because I checked about baseband version is i747mvluemk5.
b) I bought the code and when inserted non-accepted active SIM card from my another carrier, got the window asking PIN to unlock network , entered and got unsuccessful. The company said is right unlock code by IMEI sure.
So my question is does the particular Cyanogenmod 11-20140531-nighty-d2lte custom firmware prevent somehow to unlock SIM lock?
c) Do I have this KNOX issue or not, or is it prevent to downgrade ?
d) I found some KNOX remover can I apply it and downgrade after?
You should revert to a stock 4.3 ROM in order to use the unlock code.
There is a 4.3 ROM for Rogers you can use . search for a pre_rooted ROM on xda.

You cannot downgrade your bootloader.
Do not load any ROM via Odin that is older than 4.3. Don't load any att ROM as that could brick your phone too.
Was your phone ever running stock kit kat?

got error installation aborted (status 7)
I don't have KK on my i747m. I loaded the stock 4.1.2 ROM and went straight to a custom 4.4 ROM.
Did you ever have the stock 4.4 ROM on your phone? If you did, I'm not sure if you can load a stock Rogers 4.3 ROM via Odin because the stock 4.4 ROM may have altered the 4.3 bootloader. The stock Rogers 4.3 ROM from sammobile.com and the pre-rooted ROM on XDA will load a stock 4.3 bootloader if flashed via Odin. You could flash a stock ROM via mobile Odin which does not alter the bootloader.
Once you are on the 4.3 bootloader, you cannot downgrade the bootloader regardless of whether you do or do not have Knox.
If you are sure you never had the stock 4.4 ROM on your phone, you could use Odin to load a stock Rogers 4.3 ROM, unlock your phone, go back to a custom ROM.
When flashing a ROM or altering your phone's software, there is always the risk of bricking your phone. Just be prepared to deal with a possible brick.

I747MVLUEKM5
But I solved problem to revert back to stock ROM using file I747MVLUEMK5_I747MOYBEMK5_TLS
been installing not from SD card but using laptop and Odin.
After I boot the phone I put SIM card and on pop-upped window entered official unlock code.
For using Odin program, I downloaded from internet vmware fusion, after found my cd disk with windows 7 ultimate and installed it.
After installed Odin and transferred above file to internal system and put the phone in downloaded mode connected and after a few minutes I get my phone booted with stock ROM.
What I surprised I did not find official page in Wiki of Cyanogenmod for official way to uninstall their product.
So I decided not to install the software that does not have official uninstallation tool. They have installation program only.
It's not good for us regular users. Before to come into the dark room usually it has to have to see exit way clearly.

I know of no custom ROM that can completely uninstall itself. One of best ways to revert back to stock is to flash via Odin which you were able to do.
Once I got the upgrade bug, I don't stick with stock for too long.

Hi everyone,
I am looking for a way to sim unlock my S3 so my girlfriend can use it on Telus (I just got an OPO )
Before I purchase a code, I have a few questions, if anyone knows the answer
1- Will an unlock code work with my setup? (I am seeing reports of it only working on Stock 4.1 and whatnot)
2- Where is a good place to purchase a code? (Rogers a crooks with a 50$ fee and I don't wanna get ripped off online either)
Thanks!

You will need to be running a stock or close to stock ROM in order to use the unlock code. You do not need to be on stock 4.1.1 to use an unlock code. You need to be running stock 4.1.1 if you want to unlock using the free method. You may be able to unlock it using a code if you are running a stock dialler.

it's my understanding that downgrading from this will brick your phone...
Thanks for all the info!
Yes, trying to downgrade from mk5 will brick your phone.
Find the stock Rogers ROM from sammobile.com and flash it via Odin. Flashing back to stock will wipe all user data and files so make sure you backup everything you need before flashing back to stock.

The free method will only work if you are running an i747 or i747m on stock 4.1.1 including the bootloader.
If you flash back to stock mk5, you should be able to re-install cwm and CM11. There are many threads on disabling knox and install CWM.

Thanks a lot for your help sir =)

I was on CM 10.2.1
I upgraded to CM11 - I get no wireless data. My phone works but I have no APNs and I could not add them.
I tried SlimKat 9.0 same issue with the APN
I upgraded my CWM to 6.4.0.7 as I heard that caused issues when upgrading to CM11.
I bought Mobile Odin and flashed that way as I thought it might help.
Ive done the following to fix my APN
1) Loaded an old one from working CM 10.2.1
2) Run Root Tweak with the fix APN for CM11 checked
3) Done the airplane mode trick
4) Attempt to add one manually
Does anyone know why this is happening and more importantly how to correct this issue?
Yes I did pore through other threads on how to fix this but no avail.

Data does not work on ROMs beyond cm10.2 because your bootloader and modem to too old.
I recommend flashing back to stock 4.1.1, sim unlock your phone if it is not already sim unlocked, and run OTA updates to at least 4.3, then install recovery and CM11.

Thanks for the quick reply. That sounds hard. From what I'm reading going back is treacherous.
So these are the steps.
1. Load this firmware via ODIN -> I747UCDLK3_I747ATTDLK3_I747UCDLK3_HOME.zip -- What about gapps? Is that in this zip?
2. Run triangle away. (Do I need to do this?)
3. Contact my carrier to unlock my sim. (If this is carrier unlocking ie taking my att phone to Sprint etc, why is this needed?)
4. Get OTA updates. Will this come automagically because I'm on 4.1.1 and does it matter if my flash counter is gt 1?
5. Root phone via Odin with this file CF-Auto-Root-d2att-d2uc-samsungsghi747.tar.md5.
6. Install CWM if it went away when I went back to firmware - Of course it would because I'll factory reset my phone in step 1.
7. Flash away to a 4.4.4 Rom
Did I miss anything?
Step 4 is the one that scares me -- That one is out of my control. Either I get the OTA or I dont. Anyway I can "request" the OTA?
Thanks again
Be Well
From your custom ROM, run triangle away to reset counter and change things back to official.
Now flash back to stock 4.1.1 using Odin. If your phone does not boot, you need to get into recovery, do a factory reset, and reboot the phone and go through the set up routine.
After loading stock 4.1.1, do this to sim unlock your phone for free: http://forum.xda-developers.com/showthread.php?t=2529200. If you have a code from ATT, you must be running a stock ROM or a custom ROM that is based on a stock Samsung ROM in order to enter the unlock code.
You must be on a stock ROM in order to take OTA updates. OTA updates are the safest way to obtain an updated bootloader and modem.
After updating to 4.3, you cannot downgrade the bootloader as doing so may brick the phone.
The choice is yours in terms of what you want to do. As you found out, some ROMs will not function properly without an updated bootloader and modem. Mixing modem and bootloader versions may also result in a bricked phone.

To stick with 10.2 or not to that is the question. Everytime I flash or do anything like this on my phone - I get a small lump in my throat knowing I'm dancing in the razors edge of bricking it.
I know how you feel, but I've done it enough times and just accept the fact that I may brick the phone. Jtag service would cost me around $75 so I'm willing to take the chance. I'd be less willing if the phone still has warranty.
Flashing back to stock and running OTA updates is the safest route.
If you don't sim unlock while on stock 4.1.1 and you want to sim unlock your phone in the future, you will need to be on a stock or virtually stock ROM in order to enter the unlock code.
Used ODIN to go back to stock 4.1.1.

In a terminal or adb shell you can enter this to check your bootloader:
Code:
getprop ro.bootloader
In a terminal or adb shell you can enter this to check your modem (should match the baseband your phone reports in About):
Code:
getprop gsm.version.baseband
I don't believe either of these commands require root unless stock has getprop locked down tighter that AOSP ROMs; I just entered them in a user shell.
There are a couple of firmware updates for your device beyond MJB, NE4 and NJ1. Some users, myself included, had GPS problems that were a bit of a pain to fix on newer 4.4 AOSP based ROMs with the MJB firmware, but data was ok with MJB. Also, you'll need newer firmware if you decide to test drive the lollipop alphas that are floating around. There are custom recovery flashable firmware updates on XDA from a trusted developer if you decide you need that, or you might want to take a couple more OTAs if you're more comfortable going that route. You're already on MJB so there's no going back
The terminal worked
Bootloader and baseband = I747UCUEMJB
What???? I might need more updates for all the roms out there.....ugggh.
"There are custom recovery flashable firmware updates on XDA from a trusted developer if you decide you need that, or you might want to take a couple more OTAs if you're more comfortable going that route."
If I decide to use these flashable firmware updates on XDA from a trusted developer or OTA its same as this: going forward and NEVER going backward when getting firmware updates?, yes?
yes. downgrading bootloader will almost certainly cause a brick.

You guys are on point.
Last night I received another OTA to 4.4.2.
Baseband now at NE4.
Thanks again for taking the time to answer all this -- Really really appreciate it.
EDIT: Can I still use this to root my phone via ODIN or is there a different process for this baseband?
CF-Auto-Root-d2att-d2uc-samsungsghi747.tar.md5
I load this into ODIN, plug my phone in download mode and root away. Does either the file I use change or do I have to use something other than ODIN?
Thanks again
To get root, I would flash a custom recovery and flash supersu from recovery, then let supersu disable know.
The file you named looks to be outdated as it refers to the s3 as d2att. Since unified builds were released, the s3 is now referred to as the d2lte.
I have ROM Manager installed. It has an option to "Flash Clockworkmod Recovery". I just tried it and it failed and I think thats because I dont have root. In the past I've had to root my phone via ODIN, then flash custom recovery then MOD away.
In the past I rooted the S3 via ODIN. With this new 4.4.2 version do I still root via ODIN provide I find the correct file because -> CF-Auto-Root-d2att-d2uc-samsungsghi747.tar.md5 this one is probably for a 4.1.1 version phone?
I would not flash anything for the d2att at this point.
Try this:

Download supersu zip from here and place it onto an external SD card or copy it to the phone's internal storage: http://download.chainfire.eu/695/SuperSU/
In Odin, uncheck everything except f.reset time. Flash Philz. When you see reset in the status window, remove USB cable, pull battery, replace battery, boot into recovery, flash supersu, reboot.
I am fairly certain that AOSP, or at least CM, de-unified in the past few months. Not that it matters much, other than for the confusion it causes.
good afternoon, I have a Galaxy S3 SGH-I747 Model using ClockworkMod install the [ROM] [4.4.4] SlimKat d2att (at & t) Stable 9.0 and [Gapps] [4.4.x] Official Slim GApps TRDS (Slimkat) and now not recognize me the sim card. i bought this phone in amazon for use it here in Madrid. i dont know if is a Modem issue. I appreciate all the help you can give me. Thank you. (sorry for my english)
Does your sim card have a pin code that you enter each time you boot the phone? If yes, does the phone ask for the pin before unlocking the sim? What bootloader and modem are currently on the phone? Did the phone work before installing a custom ROM?
@audit13 , mine said "no service available" after moving from KK to lolli and i flashed a "write to extsdcard fix zip" and it fixed the issue , i.e. can now make and recieve calls. dont know if is same issue (or why exactly that fixed mine) but i have a KK "write to extsdcard fix.zip" if you think it would help.

Hey I have sgh-i747m canadian on stock jb . I flashed to CM 12.1 and my phone doesn't recognize sim. That means I can make calls and receive but no mobile data. Please help me
Sent from my SAMSUNG-SGH-I747 using XDA-Developers mobile app
For the i747, sounds to me like the bootloader and modem are too old for the rom.
For theni747m, is the phone running the latest bootloader and modem?
@mrrocketdog, I've never heard about that zip until your helpful post. I must keep that in mind for the future even though I haven't had an s3 for quite a while.

The problem is the bootloader and modem. They need to be updated to work with the latest ROMs.
If the phone is sim unlocked, I recommend flashing back a stock rom using Odin and the firmware from sammobile, set up the phone, run ota updates until the phone is running the latest bootloader and modem. This is tedious and takes the most time but it is the safest method in my opinion.
If you don't want to go this route, just flash the latest modem and bootloader using twrp, flash the custom rom, flash gapps.
@Budare , here is the thread to upgrade bootloaders and modem if you decide on this route rather than flashing back to stock and running ota updates as @audit13 suggested , which IS the safest route. (always always always a certain % of risk ; no matter how small , to flash anything. not trying to scare you , just being honest)

p.s. you might want to think about changing to twrp recovery as cwm has not been updated in quite a long time.
p.s.s. here's the latest twrp DL page for sghi747 att

thank you audit13, but how i run ota updates??
To run ota updates, you need to use Odin to flash the stock att 4.1.1 rom using Odin. After setting up the phone, check for software update under the phone settings.

i dont know if is because im in Madrid, but the phone doesnt get updates, thats why i want to use another rom. what can i do?
Not sure but I have received OTA updates even when the phone is not in the phone's original country. The OTA updates came over wifi.
If you want to use another ROM, you can install TWRP, boot into TWRP, flash bootloader, flash modem, flash custom ROM, flash gapps. If flashing the modem bootloader in TWRP, DO NOT reboot the phone in between flashing this files and make sure the bootloader and modem version are made for each other.
So I'm planning to switch carriers and I'm wondering how I can unlock my i747M locked to Fido that's running OctOS L 5.1.1. If I have to downgrade, how do I transfer all my current app data and pic's. Also, is it possible to keep the unlock if you were to update you phone to a higher version or install a custom ROM or install the nandroid backup you made before unlocking? Please leave me with some important things to know about while unlocking your phone if possible!
If the phone is running a 4.3 or newer bootloader, you'll have to buy an unlock code.
In order to enter the unlock code, the phone should be running a stock samsung ROM from sammobile.
I suggest creating a nandroid backup with TWRP, copy the backup to your computer, flash the stock ROM, perform a factory reset after flashing stock, unlock, flash TWRP, restore nandroid.

so, in a nutshell, i just need to downgrade my phone to a stock rom of 4.3 or below and just search up a video of how to unlock it using the keypad method?
than if i wanted to, i could use the nandroid backup i did before and flash it and still have an unlocked phone?
You cannot use the free method once the phone is running a 4.3 or newer bootloader because you cannot properly run the 4.1.1 modem on a 4.3 or 4.4.2 bootloader and the 4.3 or 4.4.2 bootloader cannot be downgraded to a 4.1.1 bootloader.
Before flashing anything, which bootloader is on the phone?

Sorry for the noob question, but how do i found out my bootloader?
If this helps, my baseband is I747MVLUFOB3
I actually just logged on to get similar clarification. I have an unlock code, but it does not work when I enter it using OctOS-M. Do I need to be on a stock rom to unlock? Can I easily jump back to a stock rom, then back again to a marshmallow rom?

From what ive heard, you have to be on a stock rom. As of google, even then, some users have problems or cant, which from what ive heard, can be fixed by downgrading to 4.3 (make sure ur bootloader is the same or your phone WILL be bricked).
Please note that this is from what ive heard and may not be accurate.
Install the Samsung phone info app from the play store as it will tell you a lot.

My boot loader seems to be the same as my baseband.
What is the bootloader version?

That sounds problematic...I am on NJ2. I am not having any luck finding anything about getting back to stock on the newest bootloader.

Do you think this one would work?

Whats a CWM anyways?
CWM is Clockworkmod with is a custom recovery. CWM is outdated as it has not been updated for quite some time. Many recent custom ROMs now require TWRP.
You may be able to software unlock the phone but you'll probaby need a UART cable and Samsung Pro tools. I don't believe Pro Tools is free.
The linked thread is from 2014 and, in 2014, many phones were running 4.1.2 which meant the phone could be downgraded to 4.1.1 using and sim unlocked using the dialler's menu options.
