After flasing 4.1.1 you have to flash lk3 kernel via twrp/cwm then you have the option INITIALLIZ. Find a lk3 flushable zip kernel I did this that way. BTW what is your baseband version???

If I helped you plz press the <<Thanks button
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] alanwu1989:
What's "lk3 kernel"? I google it, only a few results are relevant and they are all not for galaxy note 2.... :(((. Would you happen to know where I can find it?

Your phone is an AT&T Note II? What 4.1.1 ROM did you flash? Is it the stock ROM for your carrier?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tonni007:
4.1.1 is pretty old now. Look on my post for 4.3 on galaxy s3 general.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
Yes, 4.1.1 is old but I don't think there is any other way to unlock the phone for free. Is there?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] cmorningwood:
yes if you happen to read the xda homepage, about a month back there was an article up for about two weeks mentioning that carriers now have to provide unlock codes to you (not to say they wont resist) subject to a congressional finding on a previously allowed then overturned interpretation of the DMCA that prior, had actually mad unlocking your phone illegal as it circumvented access control features which was poorly defined in the DMCA and therefore causing the resulting "your allowed to do unlock" to "now your not" confusion and back again to you can today.

Whew.

In short:

If the Phone/Tablet/Rice Cooker has been

A. Paid for outright or

B. Completed its contract IN FULL if subsidized by the carrier

Then carriers are supposed to give you the code regardless of whether you currently have an account/service with them. One person mentioned getting the best results using an online chat rep at AT&T's online help center for example
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
What you said may be true in the USA but some xda members are not in the USA with American carriers.

By free method, I was referring to something anyone could use to unlock their i747 and i747m without carrier intervention.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] cmorningwood:
And this specific thread and forum also refers to the american, att branded, sold/subsidized, i747 (or note 2 respectively) which even if used elsewhere is still and american Att phone that anyone should be able to unlock.

No offense meant my friend. I know us Americans are such egocentrics (kidding, kidding) but no really I had considered this when posting originally. I am very much an opponent of carrier locks, tethering provisioning, throttles/speed capping, etc regardless of where it is occurring. In fact in all seriousness I find it a rather narrow idea that company's in today's world do this given our global nature, on the premise of revenues lost that they never had in the first place.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
I understand that many of the XDA members that frequent this forum are located in the USA but the forum title reads as follows: "AT&T, Rogers, Bell, Telus Samsung Galaxy S III". The i747 and i747m are supposedly identical in every way except for carrier customization of software.

---------- Post added at 10:54 AM ---------- Previous post was at 10:48 AM ----------

The s3 has to be on 4.1.1, iirc. The only firmware package for that is ucdlk3. If you upgraded to official 4.3 (the MJB) firmware, your screwed because you can't downgrade the bootloader. If your on the MJ2 bootloader or older, just Odin flash the stock lk3 Rom.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] htc_softbank:
The op needs to be updated to say you can't use this method once on 4.3 stock Rom and bootloader. This is because you can't downgrade the bootloader right now.

Verify ATT S3 is unlocked

Hi, (New user, please excuse any missteps) I am on a Contract with ATT and have a S3. I want to Unlock the phone Before I travel overseas. The phone still has the ATT SIM inside. I performed the steps below, however, I do not see the NW Lock NV Data INITIALLIZ option after completing the "Options [3]Perso SHA256 OFF" step. I DID see the SHA256 - - - [1] Change to SHA256 - - -[0], but do not get the NW Lock NV Data INITIALLIZ option. How do I confirm that the phone is Indeed unlocked? I don't have another SIM from another provider yet. Please suggest my options.

Hi,

the phone is OEM, no changes at all. here is what I see in the device:

Andriod 4.3

Kernel 3.0.31-2024954

Build- JSS15J.l747UCUEMJB

hope this helps...

So to be sure: I Only want to find out if my phone is now Unlocked with the original ATT SIM still inside, since I don't have access to another SIM to test it with. Since I am on the road, its hard finding a cell shop to go and try out another network SIM...

Thanks! Jura
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
If you unlocked your phone while on 4.1.1 and upgraded to 4.3, your phone would still be unlocked. If you got the phone from ATT with 4.3 pre-loaded, you will need to buy an unlock code or convince ATT to give your the code, hopefully for free.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] juurraa:
Hi, I actually had the phone since 2012 and it was upgraded by ATT awhile back (OTA). I did call them, have a few months left on the contract, so won't give me a unlock code (will deal with them later, when back home in US). For now, I need to purchase the unlock code from outside service. Can I get a recommendation on a Reliable and honest service provider, who can turn around in a day or so? Thanks, Jura....
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mrhaley30705:

at&t note 2 i317 sim unlock T-Mobile

prompt message: SIM network unlock PIN, (tried all the unlock codes given to my by AT&T), error: Network unlock unsuccessful

using 4.1.2 rom ( Jedi X12 ), tried using *#197328640# but 4.1.2 does not have the menu option [4] NW Lock NV Data INITIALLIZ, tried using 4.2.2, *#197328640# did not work

how i unlocked at&t note 2 i317 to use tmobile sim card

NOTE: these are the exact steps i took. some steps may be unnecessary. i wanted to list all steps i took in order to (a) help newbs and (b) get feedback if i made any mistakes.

1: start cwm recovery, backup rom to external sd (backup and restore -> backup to external sdcard)

2: back -> wipe cache partition -> yes

3: back -> wipe data/facotry reset -> yes

4: take out battery

5: replace battery, hold down VolumeDown+Home+Power (download mode)

6: plug in usb to pc

7: on pc, download 4.1.1 stock firmware here: http://stockroms.net/file/GalaxyNote2/SGH-I317/I317UCALJ2_I317ATTALJ2_ATT.zip

8: extract the tar.md5 file

9: open odin (make sure it says "added")

10: click checkbox for PDA, click PDA button, find the tar.md5 file from step 8, click open, click start

11: wait a few minutes until odin auto reboot phone. (walk away and came back)

12: with the at&t sim still in phone, dialed *#197328640# and follow these instructions exactly:

Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone... enjoy!!! There is no confirmation on the phone that the unlock was successfull.... just reboot your phone....

reference: http://xdaforums.com/showthread.php?t=2014982​

13: after reboot, remove battery, insert tmobile sim

14: replace battery, power on device. no prompt to unlock sim, called tmobile customer service to test out

15: say "yay!"

after that, i was able to restore my backup by flashing cwm and doing a restore from external sd card

when i restored my backed up rom, still no "unlock sim code" prompt. called tmobile customer service again to make test out again.

please give feedback and ask questions.

god speed and may the force be with you!

Picked up a plain gt-i9300 which is locked to EE (uk based) and i've tried this unlock (which worked on my last S3) but this one fails when i try to enter the NETWORK LOCK page.

I've flashed plain versions of 4.0.4, 4.1.1, carrier (O2 & EE) of 4.0.4, 4.1.1 and they all fail at the NETWORK LOCK page as i'm getting the MENU NOT EXIST message.

Is there a particular modem version i need to be running for the menu to be available? Or am i just **** out of luck? (can't even check it against the wifes S3 as she's gone up to 4.3!)

Thanks.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
I believe the gt-i9300 is the international version of the s3. The s3 discussed in this forum is the LTE version for North America (i.e. i747 for ATT and i747m for Canada). This leads me to conclude that the missing menu settings for the i9300 may not be accessible by an end user.

Try looking here for a possible solution: http://xdaforums.com/galaxy-s3
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] caboose118:

Hello!

I have a Galaxy s3 locked to Vodafone to be unlocked.

It's not rooted and using stock 4.3.

Since the code isn't working on 4.3, what would be the solution. Do we have to downgrade to 4.1.1 (how? without root? Edit: and will the unlock stay if updated?)

The owner of the phone moved from spain to here, Finland.

She can't unlock it from the carrier, because they are already here, and carrier can't access it from here.

So, we need a way to unlock it and use the new sim-card.

Edit 1:

We tried what atomcontra said above. I downloaded the stock 4.1.1 for S III, but I get MENU NOT EXIST PRESS BACK KEY Current command is 186

I looked at the messages before. I downloaded the stock one, but it didn't work.

FYI, this is what I downloaded: http://www.sammobile.com/firmwares/3/?download=7247
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DBThanatos:
Does that still work with phones that has EFSv2?

I remember i read something about not being possible anymore

And how true is is that once unlocked it remains unlocked forever? After I flashed a custom rom over that, it went plop
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
The free unlock method was designed for the i747 and i747m, not the international version of the s3.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tonkku107:
So, I download this: http://www.sammobile.com/firmwares/3/?download=9080 ?

Edit: tried... Odin did not want to flash it... what now?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
You should be happy Odin didn't flash that firmware because it would probably brick your phone.

There may be a way to unlock it for free. Check the i9300 forum.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tonkku107:
I thought so... but I had to try...

I hope I will find a way

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Flandry:
I was trying to do this for a friend with an SGH-i747. It says android version 4.1.1 in the system settings. It's an AT&T branded phone and he wants to use it on t-mobile (for which we have a SIM).

Version says I747UCDLK3 (seems to me that means the LK3 modem which someone said should work)

Kernel version 3.0.31-274808 se.infra@SEP-103#1

Compilation number JRO03L.1747UCDLK3

The phone was asking for an unlock code originally with the new SIM in. After following these instructions, it no longer asks for an unlock code, but it only allows emergency calls. I've tried repeating the steps several times. I tried turning back on the SHA256 and confirmed that it is toggled on, hoping i could at least get the phone back to its original state. Nothing. Still can't detect the SIM.

Does anyone know why this isn't working and how I can fix it or undo it and restore the phone to a functional state? I told my friend from the start i didn't have time to fix his ebay phone to work with his network and i meant it but he insisted, and now i've got this mess. Million thanks to whomever can point me in the right direction.

ETA: Repeated yet again, this time using the instruction in the link in OP. It includes a couple final steps not in the OP and describes what the outcome should be. I got exactly these outcomes this time, yet i still get a phone acting like it has no SIM. It gives the message "phone not allowed mm#6" when i first boot it up. From some searching around it seems that may mean it's a blocked phone. Are there any other possible reasons for that message?

ETA2: Checked the IMEI and it's blacklisted. Guess that solves that.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] gspears:
Bummer dude. Was it black listed on AT&T and therefore T-Mobile also? I guess what I'm trying to ask is, if the blacklist on one carrier carried over to another carrier.

I know the carriers are trying to develop a system were they all work together to combine blacklists but I didn't think they had done this yet. I rebuild phones and what will happen is I'll get a phone that's not blacklisted and then after they sell it to me they will report it lost or stolen and then it's blacklisted. The only saving grace when this happens is that it can possibly be used on another network. If they stop that, then the phone will be a paperwork, or parts.

Let this be a word of warning for everybody, be very careful who you buy used phones from.

Anyway, sorry for the OT
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
The last I heard (sometime last year) was that T-Mobile and AT&T were already sharing blacklist information, and sometime this year there would be a nationwide blacklist that all companies would use. I dont know if this has been done or is still planned though.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] gspears:
That's what I heard as well but I'm not sure any of it has happened. I had a T-Mobile blacklisted phone and was able to use it on AT&T so I don't know.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] diablo009:
I think you are quoting my message from eons past :) And I don't even use my S3 anymore.

This is VERY true!!!! I experienced it first hand... by being unable to use a TMo blacklisted device on AT&T. Had to sell it for a person for parts. Lesson learnt.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] gspears:
That's really strange because I just had a T-Mobile blacklisted device work fine on AT&T. I wonder if there are different level's of blacklist?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
I think it may just take a little time. Could be they share the info ever month or quarter or something like that. Just a guess though.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] diablo009:
This seems like a more reasonable one. Like bank accounts are settled at the end of day, probably black lists are being merged monthly or quarterly.

hi guys !!!

I am facing a strange problem !

I got i747M from Canada Kodoo with 4.3 locked. I get it unlocked via shop keeper via Root method [ coz there is a icon vRoot].

I got some network issues. My phone is not registered on network . I am using it in india.

I did some tweaks :

1. I set it to '"GSM only" mode. Then it detects my network [Airtel] towers are full but , i can make calls only at the one place, when i move to some other place it goes back to "LTE/WCDMA" Mode.

2. Other problem is that i can hear the caller but he cann't hear my voice.

Then i updated it to official 4.4.2 via Odin. Factory reset/clear cache .. but all in vain.

Can u people help me please​

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
This is a very big shot in the dark, and i doubt it would work, but you could try flashing the 4.1.1 modem from the T999L. The L and N variants are identical devices. Only the firmware is different. You probably wont get any signal with that modem, but if its at least recognized by the system, it might give you access to the unlock menu.

It should not brick or cause any harm to try. People have flashed I747 and T999L modems to the original T999 trying to get LTE, and while it did not work, they only had to flash back to their correct modem to fix it. All of these models have the same partition layout, which is why they did not cause any permanent harm.

Im not saying i guarantee anything, and if it were me, i probably would not try it and just buy an unlock code. Im just giving you another option you can try if you so choose.
