SGH-T999 unsuccessful unlock request

I have a valid unlock code for Tmobile Galaxy S3. In order to unlock the phone using Tmobile Sim card, i had to revert my rom back to tmobile stock rom. However, it has been telling me that the request for unlock is unsuccessful. WHen i check the lock status, everything is showing as locked.
If I use At&T sim card, i was able to make a call? Hmm....does this make any sense?

Same here when I paid to unlock mine.

Since you are using Tmobile S3 with AT&T sim card, have you tried using AT&T rom instead?

i did the same thing.i typed in my code and it said unlock unsuccessful.but i use a straight talk att sim and it works perfect.so i dn

Yup, i just gotta figure out the best APN settings for my AT&T line, sometimes it switched from H+ to 3g...i think it switch to 3g when i'm not actively using the data. I'm not sure when it's switching back and forth so quickly will drain the battery tho.

Solution
1 - Just dial the following keys *#197328640# with out sim
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 ON > (after choosing this option, wait about 30 seconds
turn off
2 - Insert a sim that your phone will not yet accept
3 - It will ask for the code, enter it and unlock your phone

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!

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.

Hi guys, you can unlock you N7105 via the Samsung hidden menu. [Also works with N7100 and some Galaxy S3 (SIII) variants - NOT ALL]
=======================================
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...
Quote:
Unlock your N7105:
Note: your phone must be running at least Jelly Bean 4.1 otherwise some of the menu choices are not present

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 ...
========================================
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.

Do you know if it's purely software based? I'm wondering if one was to flash a custom rom if that would affect the unlock.

I did this on my 1713 but don't know if unlocked. Should it tell you? I don't have another sim.

Just tried it on my AT&T Note II with a T-Mobile SIM and didn't ask me to provide a unlock code after doing the above OP instructions. Before trying the unlock method I turned phone with T-Mobile SIM and it asked for a unlock code.
Now will try it on my Galaxy S III running Jelly Bean.

Thanks for digging this long buried thread up just to tell us that...?

I could be wrong but I believe it would still be legal if the phone was bought before the law went into effect. At least that was my interpretation.

Correct

And if you're no longer in a carrier contract, is it also illegal to unlock?

Nope then the phone is yours ...I think....its just when u owe them for the phone

Some people believe that you still need to get permission from the carrier to unlock the phone to switch to another service even if your contract is over.
Here's a link to the docket for you legal buffs/lawyers who want to translate it for us:
https://s3.amazonaws.com/public-inspection.federalregister.gov/2012-26308.pdf
Frankly, it's not going to stop people, and it's going to take a lot for cell phone companies to enforce such a thing. There are people out there, such as Craigslist, who buy new phones and renew their contract, but continue using their old phone and simply turn around and sell their new phone at full price.

A friend has given me a Galaxy Note 2 GT-N7105 to root and change roms, I have put a few custom roms on it and rooted it, but I cannot get it to connect to any network. It didnt connected before I did any of this. I put a new o2 sim in it.
Does anyone have any suggestions on what to do now to get it to connect to o2.

Yes the IMEI number is the same as the one under the battery, my baseband version is N7105XXDMD1, I tried a couple of stock roms using odin, I am now connected to the o2 network, and I have full signal. However I still have the same error when I try and make a call it says mobile network not available. Im at a loss now as to what to try next. I also tried flashing a few UK modems, none of them made any different apart from turning my baseband version to unknown. Any help would be much appreciated. Im thinking maybe instead of flashing to the latest stock rom, maybe I should look for the oldest one and let it do OTA updates. Does anyone have a link to a default or old stock rom for this phone ? Or know how to fix this problem?
I found a post here which looked promising but it does not support this phone

AFAIK, all the N7105's currently in the UK are from either EE or 3, and are almost certainly network locked to them. If the device has been flashed with a generic ROM without being SIM unlocked, that could be the root of the problem.

unfortunately the phone is showing as unsupported i tried looking for other similar apps but couldn't see one for this phone ], I dont suppose you know of any others, or maybe one that will tell me if its locked, or if it is locked what network its locked to, so i can get a sim for that network

I wonder if there is any mileage in doing a manual search for mobile networks to see if any of them show up?

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:

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..

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.

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.
