no i had it on 4.2.1 and downgraded to 4.1.1 then unlocked my phone and tried updating to 4.3
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
I see. Did it brick via OTA update, Kies, or Odin?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Cloudzee:
It was via odin
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
Odd for Odin to cause a brick like that. Only thing I can think of is it may have happened because you were running mixed firmware.

The debrick method in the Q&A section should work though.

If someone is willing to give it a try, there is potentially another method that might unlock devices running 4.3. (Maybe 4.4.2 as well).

You must be rooted, but install Region Lock Away by Chainfire and run it. Then test if you are now SIM unlocked and report back!

Ive seen one report of it working on 4.1.2, so I'm hoping it will also work on later builds as well. You can get it from the Play Store or from Chainfire's thread here:

It works on Note 3s and S4s but I'm not sure about S3s since I'm not sure if they're subject to region locking (i don't believe so). But then again, the app might do the same thing on an S3. It does NOT work on KitKat although modem downgrade is all that is required, I believe
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
It does run on the S3 and appears to work. (No the S3 isnt region locked btw). Ive seen one user claim it did SIM unlock their T999 running 4.1.2.

You can't downgrade the modem if you're running 4.4.2 firmware. Downgrading the modem only works if you're on 4.1.2 firmware and trying the free unlock method we've had for a long time now. Not sure if that's what you were thinking of.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] iBowToAndroid:
Do you know specifically what's different in the S3 that prevents it? Because the S4 and Note 3 can be downgraded
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
I think you can downgrade the modem but, if the modem is not compatible with the bootloader, the imei may not be displayed properly and this will cause network connections to fail.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
If you flash any older modem on 4.4.2 firmware, it simply won't work. It cannot read the NV Data and cannot get any signal. Once updated to 4.4.2 firmware, that is the only modem you can use from now on.

Was anybody successful getting AT&T unlock code from AT&T while not being AT&T customer? If anybody did this, can you share experiences, what is the simplest way to approach this
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] iBowToAndroid:
They won't do it unless you can provide specific account info - names, numbers, passwords, etc. If you don't know it, order a code
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Dramadeur:
Nope.

I think there is a way other than ordering a code, which is not guaranteed to work at this point.

So, either downgrading to 4.1.1. Though am not sure if there is a working solution to this, see this post.

or maybe using this method? With kingo root 1.2.2.1915 and NsPro 6.7.0

But I wonder if it's gonna work now.

Has anyone done unlock on 4.4.2 i747 recently?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] galets:
This nspro box is pretty pricey for casual user, unless you are running a shop... I wonder what unlock method are they using. Since the post references flashing some old modem, maybe this modem will actually work with 4.4.2 NVRAM?

Another speculation I have is: the post mentions writing down IMEI and doing IMEI repair. I am curious whether whatever they do for IMEI repair will actually be capable of overwriting the 4.4.2 NVRAM, which is unreadable by older modems with data which actually is readable. Those folks here who tried to downgrade modem only - what was the effect of it? Did you only lose baseband, or was the whole phone unbootable? If it's only baseband, then maybe there is some way to achieve modem downgrade if you restore NVRAM, backed up before downgrade?

UPDATE: Another thing I just thought of - if modem downgrade issue is that it cannot read NVRAM, what if one restored an NVRAM backup from donor phone, and then did an IMEI restore?

UPDATE2: I am also seeing reports about successful unlocks using "octopus box" and "z3x box". As far as I could tell, all they do is interact with service programming, same way as DFS and QPST do. So, there clearly is a way to do unlock from PC, we just need a know-how.

Or, maybe I simply don't know what i'm talking about, that's always a possibility :)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Dramadeur:
Alright, so I successfully did unlock by code. I think ordering a code is the only way to unlock i747 now.

ONLY way to unlock an S3 on 4.3/4.4.2 is a purchased unlock code
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mji2015:
I can't even get past the first step

I have tried putting the code to start the process, but what I get is this "Connection problem or invalid MMI code." I am running slimkat 7.0 on my phone. I noticed the message that says you can't downgrade your image, so is that applicable to all situations, or the fact that I am running a custom image make a difference?

I got a AT&T S3 and had AT&T send an unlock code and when I tried it it didn't work funny how big Corp. can't figure out h0w to give Correct directions. As att said put another company's sim in and type code, Which didn't work also found another method with some code to get into a secret menu, also read if you keep trying it will Hard lock the phone and then you'll have to send of to samsung to have repaired but after having this phone "I" am of the opinion that its not worth time or effect.I am sure others think different but the battery issue is really over the top I charge my phone 3X a day I'm old no one calls me or text i get very few Emails.. I am on 4.4.2 it is rooted and it has marked the phone so if you have a Warranty don't root, I wanted to get rid of all the extra App's that Samsung AT&T and Google have put in,It;s incredable how many New battery kills in couple hours.

Anyway I had a Question about entering the unlock code Mine has ATT at the top and I'm using Straight Talk, on my unlocked AT&T IPHONE 4 when I swap back it says TFW but my S3 say's ATT. I used an T-mobile to unlock, If you have a link to HOW TO UNLOCK YOUR S3, I really want to see if this help's this phone as it also freeze's Lock's up have to reboot some times 2-3 time's a day I have very few app's installed and I also try to do everything as a new phone, and maybe someone is using a better root file that seem's to be working.

Code should never fail as long as software is 100% stock. If it did, you ordered from a crappy service. Plenty of good, reputable ones out there
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] UnderPL:
Works on telus SGH-i747M. If you're on 4.1.2 and have telus, you have to flash this file I747MVLDLK4_I747MOYBDLK4_TLS (available in sammobile) if you flash an ATT firmware you will see not the entries in the hidden menu. If you can't flash with ODIN, mobile odin will do the trick.

does the unlocking technique work on 4.4.2?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
It won't work with 4.4.2, the hidden menus were changed after 4.1.2. The same codes will no longer bring up the menus and some of the menus are no longer present.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
What he said,

Or, if you are off contract you may be able to get the code from your carrier - but you need to be on a stock rom, or maybe only a stock based rom.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
If a person has an i747m and they flash the stock ATT 4.1.1 ROM, this would probably brick the phone because the bootloaders and modems are not interchangeable.

it will not brick the phone, I did it

Did you use desktop or mobile Odin?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] UnderPL:
mobile odin
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
Mobile Odin doesn't flash a bootloader while the desktop version does which probably explains why the phone was not bricked when cross flashing a rom.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] nkolvek:
What about downgrading to a previous 4.4.2 modem if already on a 4.4.2 modem? I have a i747 on the FNJ1 OTA which has a locked bootloader. I've already deknoxed and rooted. But since the bootloader is locked is it possible to flash the ATT NE4 4.4.2 bootloader without issue? Not really wanting to brick the phone but I do have a md5 for the bootloader should it get borked.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
The bootloader on the i747 and i747m have never been locked. Running a bootloader unlock program is almost guaranteed to brick the phone.

flashing an older modem onto a newer bootloader will not bring up the hidden sim unlock menu. It has been tried by others without success.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] masstechamman:
the firmware download link is not working ,, i need to unlock my phone asap
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
You cannot use the free method if the phone is running a 4.3 or newer bootloader. If the phone is running a 4.3 or newer bootloader, attempts to flash 4.1.1 may brick the phone.

Hate bumping an old thread but looks like I have to!

I just acquired two AT&T Galaxy S3. In my haste I rooted/put in CWM 6.0.4.7 and CM 10.2.1-d2att which is 4.3.1, baseband I747UCUFNJ1

I see that this post http://xdaforums.com/showpost.php?p=51284815&postcount=104 references where you can download AT&Ts 4.1.1 to put on your phone via ODIN. My question is, now that I have a custom mod and rom on my phone how can I tell which bootloader version I had? I'm also guessing if that I try to put the 4.1.1 image via ODIN, it will hard brick my phone.....or will this work?

The problem is moot now. AT&T now gives unlock codes for free.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] RockinRita:
I bought my i747 off eBay a few months ago now and have tried unsucccessfully to unlock it. I have yet to try the method mentioned here out of fear of bricking my phone. (I previously hard bricked one phone and soft bricked another which took a long time to get back up and running.)

The first method I tried to unlock by was the one found on WonderHowTo after successfully and quite easily unlocking my T999L from Brightspot Mobile running 4.3 to work on T-Mobile. My problem with the i747 is that NW Lock NV Data INITIALLIZ doesn't show up in the Network Lock Screen menu. After trying countless times and never getting that option I gave up on it and contacted AT&T for an unlock code as years ago I used them as my carrier. They sent me a code and I imputted it but it didn't work so I tried again thinking maybe I misentered a digit. When it still didn't work I called them back and asked for another code. It got bumped up to tech support and a few days later I got an email back saying my phone can be unlocked and the code is fine. I tried again but no luck and then again with no luck. I tried the WonderHowTo method again but the menu stays the same.

Does it have anything to do with the i747 running 4.4.2? Is there any other possible way for me to unlock it without downgrading or having to pay for an unlock code which may not work and thus hard lock the phone to AT&T. I really need something simple as I am not technologically inclined and don't want to brick another phone or hard lock it.

Thanks for all the help!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
You cannot use this method if you are on 4.4.2. It just can't be done. Others have had similar issues using carrier codes though. I suggest searching these forums for threads on that. Online services to unlock it aren't that expensive if you shop around.

BTW, the T999L is actually a t-mobile phone already, so it didn't need to be unlocked to use it with them. Just so you know in case it turns out later to still be locked.

As for the code, make sure you are running stock, with the stock unmodified dialer. Other than that I'm not sure what the problem could be.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
Bad news: You will not be able to use the method in this thread to unlock your phone. Once the phone is on the official 4.3 bootloader and modem, or newer (4.4.2), you can not downgrade to use this method or you will brick the device. The WonderHowTo article is the same method as described in this thread. At the top of the article it indicates it is from a year ago, but the comments date back over two years. It was probably written before the release of the 4.3 stock rom for the i747.

Regarding the codes from AT&T, I believe you must be on a stock ROM with stock dialer for one to work, when you are on the 4.3 or newer bootloader and modems. A number of the stock based ROMs have dialers from other devices and therefore will not work. I think I have seen conflicting reports about the code working with root and custom recoveries.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] RockinRita:
I reread this thread and got totally confused as some replies made it sound like it is possible and others saying you will brick it. After rereading the first reply, I realized that was the same method as WonderHowTo.

So then can I root first and would that make it easier to unlock? How do I know for sure if this is rooted or not? My T-999L is rooted but not running a custom rom as I didn't care about that and just wanted to get rid of bloatware.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
I don't know that root would make it any easier to unlock. In fact, if you are not rooted I would unlock while on stock and before making any changes. To check for root the first thing I would do is look in the app drawer and see if the SuperSu app is there. If present you are rooted, if absent you may be rooted via superuser. There are several root checker apps that will give you a definite answer.

I seem to recall seeing comments that you only get 5 tries with the AT&T unlock codes. Those comments may have been before the change in laws requiring US carriers to provide an unlock method to customers not on contract.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
When you insert a non AT&T Sim card, does it prompt you for an unlock code? When you enter it does it give you any specific error message?

I ran across a thread where someone mentioned the code they got from AT&T didn't work until they entered it using a non AT&T Sim.

Hi,

Been using this phone for over a week now and extremely satisfied.

Since a couple of days I have noticed that on a random basis whenever I press the power button to wake the phone, it takes a while to come back on. Sometimes it takes even up to 4 seconds to wake up. It's very annoying.

What I have observed is off the phone is unused for a while then it happens more. If I wake the phone immediately, then it wakes up very fast. Sometimes even on an incoming call its delayed for a couple of seconds though not everytime.

I have flashed the official 534 official Generic Indian FTF twice now and updated to 257 but still this issue is present.

I am downloading RomAur as I type, will flashing it help?

The phone otherwise is super snappy with no problems.

Any input will be highly appreciated

Thanks in advance :)
