Can't unlock my phone.

Hi all,
I tried to unlock my phone with the code provided by cellunlocker.net and no luck.
Method 1: when I insert my t mobile card, it doesn't ask for an unlock code( it should cuz this is a non art sim card right?)
Method 2: after punch in #7465625*638*(my unlock code)#. Nothing happens. (It should say something like unlock successful or not right?)
Heck even I can't check the lock status of my phone. I type in *#7465625# and didn't bring up anything.
Method 3: i type in #7465625*638*# and wait for it to ask the unlock code. It did nothing. Didnt ask for anything.
How can I enter my code if my phone doesn't ask for it. And it locked cuz i can't use t mobile sim.when I inserted t mobile sum it says no sim card.
Plz help. Any ideas or advice would be greatly appreciated.
My phone is att i747. 4.0.4. Baseband i747uclh9.

I used the following on my S2, when I did, I am pretty sure I saw an option for the S3 as well. Might be worth a shot.

Also, are you on a stock or custom ROM? I've read that that can be a variable as well.

Thanks for the response. My phone is running stock ICS.
THe thing that bugs me most is that it doesn't prompt the network unlock screen, hence I can't enter my code.
The link you sent me apparently works for the att s2 sadly.

I wouldn't even waste my time with cellunlocker.net I bought an unlock code from them tried ALL the methods they gave you in the email and they didn't work I eventually took it to a cell repair guy locally and he unlocked it for me for 15 bucks and it was a factory unlock like it would be sim free
Galaxy SIII via XDA premium

I think I will root and put a rom only phone and try the unlock code again. Otherwise I am now having a paperweight.

What I meant was....in the app itself, AFTER I downloaded it from the Play Store, there is a tab to select the S3....inside the app. Did you actually download it and look at it? Just checking.

Doing a NAndroid and I am going to try this. What sucks is I don't know anyone with a micro sim from Tmobile here at work
EDIT
Didn't work, would not/could not save EFS folder from step 1.

I've run into the same issue here only I got my unlock code straight from ATT. SGSunlocker won't save the efs (even though it's in the save location it doesn't register as being saved) so it won't go to step 2. The unlock code entry sequence you mentioned doesn't work either (that's what ATT gave as well).
Haven't tried a tmobile sim yet though, just got the code yesterday.

[Q] [Solved] Unable to unlock Note II (SGH-i317m)

Hello XDA and Happy New Year!
I have a rooted Note II sgh-i317m locked to Bell Mobility. I would like to use it with another carrier. I have asked one source for an unlock code, and verified that he received the correct IMEI for the phone, but he said he was unable to get one. I have tried "00000000" but that doesn't work.
I rooted it to try GalaxSim Unlock from the Play store. GalaxSim says it is incompatible with this device. When I click "show details" I get "undefined" for IMEI, Sim Lock status, Product code, Serial Number, and all the rest of the fields. (I believe the app is using the android SDK to query the device for these settings and getting nulls.)
Rooting was a piece of cake with Odin, but how do I unlock my phone?
HB
edited to add details:
Android 4.1.1
Build number JRO03C.I317MVLALJ2
My root method was from galaxynote2root.com; it apparently doesn't touch the firmware.

try this method?

Yes, this worked just fine! I am now happily using my Note 2 unlocked from Bell (AKA Hell) Mobility on Fido LTE.

rogers sgh-i317m
HELP! I have a note 2 from rogers, i recently tried to do the service mode unlock. (#*197328640#) followed the instructions but i was missing the option 4 nv data. found out later that it was 4.1.1 i had 4.1.2. So got impatient took it to the local cell unlocker fella. He ran into trouble with entering the unlock code then attempted a process that reversed what i did and entered the code, this seemed to work the unlock with the code was successful. Or so it seemed until i inserted my telus sim card then my $780 dollar phone that i just paid cash 2 days ago wont accept the sim or any other including rogers. I tried rooting and i put 4.1.1 back on this got me to the point where it will accept a rogers sim but data will only run edge and call out if i set it to gsm only in network settings this is the only way it will accept a rogers sim only

unlocked
me too , i can not unlock my note 2 canada sgh-í7m

Does this method work if im on the latest 4.3 from Bell?

No.

i know it a little late but if there are still people reading this today, well... this worked for me, and you need to be on 4.1.x variant of the note 2 i317/m rom.
I was initially on a 4.4.2 Koodo variant and downgraded it to a 4.1.1 Bell variant before i was able to successfully unlock the phone, since anything after 4.1.x that method is blocked/unavailable/patched. After i was done, my Videotron sim card was accepted and LTE is working flawlessly. Flashing Bells 4.4.2 rom posed no issues and phone was back to normal. Software updates were being checked normally (even tho no official lollipop will ever come from Samsung... but just saying) and nothing was acting out of the ordinary.
only problem is (but shouldn't really be anymore) that your KNOX counter will trip and will stay stuck at 1 due to some hardware thingy being physically changed. This is because of the Security enhancements being violated when downgrading from 4.4.x to 4.1.x. (kitkat to jellybean is a big nono to the SE, but the other way around or kitkat to kitkat is fine)
if any issues or questing feel free to ask GL

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?

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...

Yea after all that it's safe to upgrade back to 4.1.2 or 4.2.2 or nearly any compatible rom you like.

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.

You do not really need the unlock code. Do a search in the forum as you cam just unlock it with Samsung' service menu.

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:

Galaxy S3 Unlock Code not working

I have a galaxy s3 and a valid unlock code from tmobile. The problem is when I enter the unlock code in, it says "sim unlock network unsucessful"
I called T-Mobile and they told me to try again after 24 hours, but it still does not work. Could it be because I am on a custom rom (AOKP MR1) ?
I am in India and am trying to use the phone on a local carrier here, such as aircel. What should I do? Thanks

Yup. You need to do it from the stock TW dialer.

Sim card permanently LOCK?

I got an unlock code for Galaxy S3 from TMO. I enter it and it didn't work. It said "network unlock request unsuccessful". I tried it for a couple times, wifi on, different carriers, the code still no good. Called TMO again and they said the code is correct verifying the IMEI. Anyone experience this? (It's on CM 10.2).
They also said my phone most likely permanently LOCKED the sim carrier!!! I was like WTF. I don't even know there's such thing. How is it possible the sim carrier being permanently locked.Now I'm stuck cuz they can only generate one code per IMEI (according to the rep). If I buy an unlock code online, will it work?

If you do too many unsuccessful attempts to unlock the sim then it can permanently lock it.. And did you try it with CM? With the s3 it would only work with touchwiz, try it with that

In the GENERAL section for our T999 there is a thread by "mrgodai" named "Sim Unlock".. I just did it last night and it worked. You WILL have to downgrade to 4.1.1 (I used the root66 4.1.1) via ODIN.. Then you follow the OPs instructions, then once it shows SUCCESSFUL you can go back to your backed up nandroid to whatever ROM.. I'm using CM11 4.4.2
