i317 unlock: code vs. cable

I am trying to get my ATT Note 2 i317 unlocked. It looks like there are 2 ways to do it. Cable unlock vs. code unlock.
I have code unlocked phones before, and it works fine. Looks like the cable unlock is a hack to the same end. It is a cheaper way.
Does anyone know if the cable unlock is a good way to unlock, or if there may be consequence? Is it worth saving the $15?
Thanks.

Sim unlock ? Check the recent threads for a phone code to bring up internal unlock. Seems to be working well for many people. And its free!

Just dial the following keys *#197328640#
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, Hit menu then go back to [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone. UNLOCKED

I confirm this works on T-889 and T-999 (GN2 & S3)

ROM, modem version? It's difficult to help with no knowledge of your device. Here is a thread for this method though that most likely answers these for you.

ROM is stock. though I rooted it. baseband version is i317ucalj2. thanks

The cable method is slightly sketchy, because you will be giving a stranger complete access to all personal information on your pc and phone. If you trust the person, or can verify their reputation, why not?
If you are with AT&T and are in good standing, you can ask for your unlock code for free. It takes two days or less to get it.
But you have the correct modem installed (J2) to perform the above listed steps. If you followed them you should be unlocked. You would have to verify it by using another carrier's Sim card.

Will this method also work on a stock Note 2 i317? I have searched for two days now for a way to unlock my Note 2 with no luck.

It fails for me too. That code just gives me an error "Connection problem or invalid MMI code"
It's an ATT note 2, GT-N7105. I'm running Liquid smooth 3.2 with the kernal that comes with the rom. The baseband is I317UCUBMJ. I don't get it.

The modem (baseband) has to be J2. It's the only firmware with the unlock menu.

Thanks, I know the modem is really old. It's the only thing I've never been comfortable flashing. I guess I'll update that tonight too.

Unlock Code From AT&T Not Working - What Can I Do? [HELP]

I was given the unlock code and it still says request to unlock network unsuccessful, it's eligible to be unlocked...
All help would be greatly appreciated.

Should I try flashing over back to this stock rom and then see: http://server10.stockroms.net/download/GalaxyNote2/SGH-I317/I317UCALJ2_I317ATTALJ2_ATT.zip
I hate being stuck in a rut like this, already had my account transfered to a T-Mobile microsim. This is driving me nuts...
The person I bought this phone from said they updated but then when I checked it was still at 4.1.2 and said something about update interrupted...

Or which of these should I use: http://www.scottsroms.com/downloads.php?do=cat&id=71

Flashing a Rom won't unlocknyour phone..... Also what do you mean your still on 4.1.2?? That is the latest Rom for the phone. ... Where are you obtaining your unlock code from? The only time att provides it themselves is over the phone. You sure your not getting the wrong code?
Sent from my Xperia X10 using xda app-developers app

Yes I got the code from AT&T over the phone, called them twice and got the same code 1-800-331-0500 they gave me 41907314... According to this: http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unlock-sim-for-free-on-gsm-galaxy-note-2/ if ya take the newest update, ya can't sim unlock the phone cause it takes out the “NW Lock NV Data Initiallize” (Step #9) according to YouTube user comments...
THIS IS WHY I'm wondering what Stock firmware I need to downgrade back to in order to get that option again and be able to sim unlock my phone.
So I'm wondering if it's I317UCALJ2 or I317UCALK7 that re-enables that option for me. Right now I'm on I317UCAMA4...

Sorry bout the 2 posts, I thought it'd auto-append them to my main post...

Okay now I keep getting errors on installing about a signature and then two file locations sdCard0 and I think extsdCard...
How can I fix this do I copy the image to sdCard (InnerSD)? Or do I need CWM to install for Scott's Stock ROMs?

Yup that worked, I had to use Odin and this image http://server10.stockroms.net/download/GalaxyNote2/SGH-I317/I317UCALJ2_I317ATTALJ2_ATT.zip and followed these instructions on installing it: http://androidromupdate.com/2012/11...y-note-2-sgh-i317-original-factory-stock-rom/ then unlocked it with the directions galaxynote2root.com had listed...

No I mean while doing this process? Odin thing.. does it matter which SIM I have to keep in note

This http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unlock-sim-for-free-on-gsm-galaxy-note-2/ is the tute I believe, gotta remember it's been 2 months since I did this, so I'm not quite 100% certain. LoL
I'll be having to do it all over again too, by the end of this week possibly, since some jerk decided to steal my note 2 I had to go to ebay and win a new one.
I don't think it'd matter during the Odin flash with a AT&T sim card or T-Mobile one in it, I can't remember if I did it with or without a sim card, but to be on the safe side I'd do it without a T-Mobile sim card in it, just for that first successful boot... Then do the 4.1.1 unlock code method, take the back and battery off then pop in the T-Mobile sim card(Or whatever other non-AT&T carrier sim card) and see if it done it correctly...

I bought an AT&T live demo note 2 that was used in an AT&T store. I used this method from youtube, popped in my niece's T-Mobile microsd and dialed 611. T-Mobile's customer service rang and answered showing it worked. You need 4.1.1 to use this method though. I'm going get me a microsim today since my vibrant doesn't use the micro.

The above is not true - if your phone has upgraded firmware, you will NOT see the item "NW LOCK NV RAM...." in your "NETWORK LOCK" "PHONE CONTROL" menu.
So, the ONLY two solutions are:
1) keep bugging ATT to create a case for you and investigate
2) downgrade to 4.1.1 modem (NEED TO READ/UNDERSTAND HOW TO FLASH etc.)
then apply the Samsung service menu "fix" as shown in the above video...*
*Then, you could upgrade to newer ROM... if you wish....:cyclops:

[Q] My galaxy s3 won't recognize any sim?

i have the AT&T Samsung Galaxy S3 SGH-I747. the phone is already unlocked so i know it should accept foreign sims but it doesn't recognize any sim i put in it. so far ive used 3 different simple mobile sims and none of them have worked. i called AT&T to find out if my IEMI was blocked or blacklisted but they said no, the phone should be working perfectly. plus weird thing is, i get the signal bars next to the battery as if the sim is working but it still says "No Sim. Insert Sim Card"
the phone is rooted so i was wondering maybe that has something to do with it? the phone was working perfectly fine until i rooted it. the specs are:
Android Version: 4.1.1
Baseband Version: I747UCLEM
Kernel Version: 3.0.31 - 274808
Build number: JRO03L.I747UCDLK3
please i am very desperate to get it working by tonight. does anybody know why my galaxy s3 won't recognize any simple mobile sim put in it? is there software im missing or updates i need? i already tried unrooting my phone, no luck.

yes the phone is unlocked. maybe i forgot to mention this earlier but it was using a simple mobile sim card perfect before i rooted it. i called AT&T international and they gave me the unlock code after i asked. i didn't need it tho because they told me if it wasn't unlocked, after i put the foreign sim in, it would prompt for the unlock code but the phone never prompts for one, just says "No Sim insert Sim card", something along those lines. further more i was informed that if it wasn't unlocked, it would say "unrecognizable sim" instead of "no sim". the fact that it says "no sim" means it won't read the sim card. the thing is no matter what sim card i put it (i tried 3 or 4 different ones) the phone still says "no sim"
i tried changing the modem to every single one compatible with the SGH i747 model and nothing helped. i tried changing the modem to a Tmobile modem because i know simple mobile uses Tmobile radio towers but that didn't help at all. i deleted all the cache and unrooted the phone but that didn't help so i rerooted it again. i don't know im just extremely frustrated right now. i've spent hours on the interenet and called AT&T international countless times to try and fix it but they always tell me its the sim cards fault but i know its not because i've tried it in other phones and they work. i'm just looking for a miracle here.
oh i did try to flash a custom rom and kernel but it didn't work and i received an error message and rebooted it without tampering with the rom and kernel again. maybe that has something to do with it?

Try doing a kies factory restore mate.

You have to be on completely stock 4.1.1 for this to work...

Same Problem
Sadly to say I have the same problem but on a new Samsung Galaxy Note 3 N900V. I bought it online and it was supposed to be factory unlocked but it doesn't work on Fido, koodo, or bell; so I am not sure if it is factory unlocked. It says No SIM on all three sim cards. I tried rooting and it is still the same. I don't know what's wrong but I tried contacting Verizon who is the carrier of the phone but you can't get help unless you have a phone plan with them. And then I want to be using this on koodo and they won't help you because the phone is not from them. I am going crazy, anyone know how this can be fixed.

[Q] Trouble with SIM unlocking T-Mobile Samsung Galaxy S III

Hello,
I've had a long saga of failures trying to unlock my T-Mobile Samsung Galaxy S III (aka sgh-t999). Firstly I started by trying to convince T-Mobile to give me the code but they gave be the bureaucratic cold shoulder for a year. After threatening to cancel they finally produced an incorrect SIM unlock code for me from Samsung. I tried it and it failed.
I then took my phone to one of those shady SIM unlock places in London and paid them to do it. After a day of waiting they sent me an email of the same, incorrect SIM unlock code which again failed to work.
I decided to try a common method I found all over tutorials that works as follows.
Go to the dialer
*#197328640#
[1] UMTS
[1] DEBUG SCREEN
[8] PHONE CONTROL
[6] NETWORK LOCK
[3] PERSO SHA256 OFF
Wait 30 seconds then press Menu and back
[4] NW Lock NV Data INITIALLIZ
Wait 60 seconds then reboot
Sadly no matter what I do that last menu option simply does not exist on my phone.
This fails on Android 4.1.2 which was on my phone when I started so I recently got a stock 4.1.1 ROM which the tutorials said was necessary. So I rooted my phone, installed ClockworkMod recovery so now when I go into recovery mode I get that CWM. I then used that to install a pre-rooted 4.1.1 build and tried to do the above SIM unlock method and it sadly it failed again in the exact same way. Option 4, NW Lock NV Data INITIALLIZ does not exist.
Does anyone know of anything I can do to SIM unlock my phone? Anyone know of any specific links to firmware and or OS ROM images that they know installs an OS that this works on? Are there apps one can run as root that will unlock? Remember I can't use anything that goes through Samsung because it ends up being incorrect.
Thanks for the help.

Your rom version has nothing to do with it. Your modem must be 4.1.1, but it wont work if youve ever updated to 4.3.
The code you got is not wrong. Especially if you got the same one from two sources. Its based on your imei so every decice has its own unique unlock code.
There's a thread in AT&T forums where someone posted a way to get it to work if having problems. Its at the end of an unlock thread in the General section I think. See if you can find and try that.
Hope it helps.

Can anyone explain to me what the 4.3 update does that stops this unlock proceeding? Surely the update can be removed.

Hi guys, you can unlock you N7105 via the Samsung hidden menu. [Also works with N7100 and some Galaxy S3 (SIII) variants - NOT ALL]
#############################################
I can confirm the unlock survives ROM flashing
#############################################
Before doing the instructions below, please double check your phone that it is actually LOCKED by inserting a sim card from a different carrier/provider...you may or may not leave that sim card on the phone while unlocking
Note: your phone must be running at least Jelly Bean 4.1.1 (if 4.1.1 does not work, try 4.1.0) otherwise some of the menu choices are not present
Just dial the following keys *#197328640#
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....
To test, just insert a sim card from a different carrier/provider. If the new sim card works then your phone is now unlocked.
I have done this to my other Note 2 N7105 originally locked to Orange.....
========================================
Do this procedure AT YOUR OWN RISK
========================================
To those who were able to unlock their phone with the method above, can you please post in the thread and let us know which phone model (N7100 or N7105) you have, Country and Network/Carrier your phone was locked to...... and if I have saved you some cash, please click the Thanks button or the Donate button on the left just below my name to buy me a can/bottle of Heinekken, Quilmes, Budweiser, Fosters, Tiger, Stella Artois, or San Miguel :cyclops: ...
========================================
NOTICE:
To those having "Conditional Call Forwarding" pop up message or similar pop ups appear everytime you make a call (but they disappear within a few seconds), this is normal with an old sim card, or when using a ported number. There is no restriction to calls or internet or whatever. This is confirmed by my provider when I walked in and asked them about it. They even showed me one of their sample Note 2's and S3's having the same message.
========================================
I have mentioned in my old thread that there was a pop up message that says "Conditional call forwarding active" everytime I make a phone call using another SIm card that the phone was not able to use before unlocking.
I can confirm that this was due to my Sim card. It is a very old O2 sim card that I have used for years. I have tried that Sim card on another factory unlocked phone (Galaxy i8160 bought from P4u) and it had the same message.

Then go back one step by pressing the Menu button and then select Back.
This will take you to [6] Network Lock options
Choose [4] NW Lock NV Data INITIALLIZ
Wait for a minute then reboot your phone.
Insert a SIM Card from a non-AT&T carrier
IF it not help to you, you need downgroad FW.
2) if you have 4.2.2 or more(4.3, 4.4.2.)
You need to wach this video and unlock your device! youtube.com/watch?v=KVrhNO__9JY
You need downgroad MODEM FW(NOT ANDROID VERSION!!!) and use *#197328640# from 1 step.

GT-N7100 carrier unlock not working
Ok, so I tried to post this in the appropriate GT-N7100 carrier unlock thread, but I'm too n00b 'round these parts so here I am making this thread.
So this phone was initially locked to Telus, but I'm trying to unlock it so it can work with Rogers. I already possess a Rogers MicroSIM card that lives in my S3 so I have a valid card to test. It has Cyanogenmod 10.2 installed on it, by me, which was done about a year ago. I also think, at the time, that I attempted to carrier unlock it, but I can't remember if it was a success or not. But right now, I have been tasked - again - to carrier unlock this device because it apparently doesn't work.
I now believe that to be the case, as I have my S3's SIM in it right now and the phone displays a message saying it can't connect to the network (Rogers). Yes, I have manually scanned for networks, and they do appear, but I can't connect to them. I also tried dialing *#197328640# to reveal the hidden carrier menu, but when I press the call button it says there's no mobile network...
That makes no sense, this is supposed to be an ingrained menu, why would you need a network?!
The phone's details are as follows:
__________________________
Model: GT-N7100
Android Version: 4.3.1

Kernel Version: 3.0.64-CM-g9d16c8a, [email protected] #1 , Sun Dec 8 11:30:23 PST 2013

Could this be solved by reverting to a stock ROM? Or can I keep Cyanogenmod? Because I'd really prefer to...
If any further details are required, I'll do what I can to answer. Please, help me get this phone back to a service ready state!

@FlashExplorer you have to be on a stock ROM to access the hidden menu to unlock

I see! I will revert to the stock ROM and then install Cyanogenmod afterward.
Thank you very much! :good:

Not working for N7100
After tried with 10 different firmwares including the very first one rolled out (I tried it with a full Stock including modem, boot, hidden, recovery etc)... I can conclude that this method does not work for N7100 (exynos based).
After reading the posts, I saw that no one with a N7100 reported success, everyone stuck up with the patched menu. So, I suggest to remove the N7100 in the first post since it does not work for it..

Sorry for asking this but with lots of people making topics about same topic its geting confusing.
I'm looking to unlock 2 x Canadian Note II I317M's
# 1.) Is running NH2 4.4.2 Firmware
# 2.) Is running MK5 4.3 Firmware
So can I just downgrade the modems to MODEM_I317MVLALJ2 rather than downgrading whole Rom If so how can I do this?
Only asking because some are saying you can and some are saying you can't. Sorry again for asking this. I just don't want to brick these phones. One is for my pregnant wife and one is for me as our 2.5yr old broke both of ours and got these ones second hand but they are locked. Just don't want this to be wasted money.
Thank you all xda'ers in advance

Unlocking Nokia Lumia 520
Hi, will the steps you posted to unlock the Samsung phones work on the Nokia Lumia 520?
I bought this unlocked phone in the UK and it works with sim from any UK providers, however when I take it to Argentina it won't recognise the SIM cards from local providers. Somebody mentioned that it may have something to do with phone bands, that it may be unlocked for use in Europe but not outside of the EU...I've never heard of phones bands so not sure about this. I'd be grateful for any tips you could give me.
Thanks!!
