Unlocking a sgn2 on O2 network (uk) - Galaxy Note II Q&A, Help & Troubleshooting

Hi folks.
I'm switching networks from O2 to talktalk (vodafone) and I'm wondering if anyone can direct me to a free method of doing this. I've watched the videos on youtube that allow it to be done by dialing “*#197328640#” on the phone but when I enter the network lock section it says "MENU NOT EXIST"
I'm guessing this is an O2 thing so can anyone help me find a way to get my device unlocked?
ps. Hope I have this in the correct section. I've also tried searching on here but no joy.
Thanks

GalaxSim worth the couple of bucks.

I think you have to downgrade to a 4.1.1 rom first, unlock your phone then flash a 4.1.2 rom.

I've tried using galaxsim but I'm getting
"unable to read NV data"
You guys are saying it's worth the money but the app appears to be free. I can't see a paid version only a free version.

It will ask you to buy if you want to use it to unlock.

Thanks for the reply's folks.
I downgraded to 4.1.1 to try using the *#197328640# method but that hasn't worked.
I've tried using the old version kdogguk posted but i'm getting invalid IEMI number now but it's saying my phone is unlocked
my phone is locked tho as it won't take my new talktalk sim.
My phone was stuck on boot screen when I downgraded and I had to root though odin then reset it before it would work so I think I've downgraded to the wrong firmware as it is now branded O2 firmware where as before even tho it was locked to O2 the firmware was neutral (not O2 branded).
I've rooted as I said but it won't install custom roms so I have a problem now. Going to upgrade to 4.1.2 but need to make sure I have the right firmware this time.
I'm having some time of it right now lol

This galaxysim app is now saying my phone is unlocked but it won't take my talktalk (vodafone) sim

Still no luck? My note 2 was on o2 first thing I done was root it, tried that code but didnt work then used galaxsim its free but said it could be done paying £2 something. Then I installed a standard btu rom. Funny thing is not tried diffe sim yet. Just hate locked phones
Where abouts in UK are you?
Sent from my GT-N7100 using xda app-developers app

on my phone it says my device is unlocked but when i try to call any number it says not registered on network, what's the problem?

turn off data. turn off mobile. turn them back on. reboot.

Galaxsim was saying my phone is unlocked but it wouldn't take my talktalk sim. I ended up paying £9 to get it unlocked on ebay. Working fine now.

Strange because my phone is O2 but I've been running it with a 3 sim from day one.
They should be unlocked by default.

Is your phone unlocked? Check to see

I got my UNlock code put in a at&t SIM..... put in code... then it said unlock successful...
But upon checking this unlock with this code.
*#7465625# it still says locked!!!
Will someone punch in this code that has there phone unlocked and see if it says network lock off.
Or if it still says locked!!!???
It's driving me crazy......

I purchased mine as unlocked but haven't had the chance to try another company's sim card on it to verify that.
I checked with the *#7465625# code and it looks exactly like yours.
I unlocked my sgs2 and tried that code and everything is OFF.

It looks like you are in different ROM. To unlock ur phone you need to be on stock ROM!
I did it on my s2. I was unable to use code on AOKP so i flash stock rom, unlock , rooted again and back to stock again.

I requested and received the unlock code from T-Mobile. I tested this by making a call using an AT&T sim card.
My screen is identical to the one above, including the typo. My phone is definitely unlocked!!!
Same thing, as all of you. I get the same pop up. I tried it yesterday with an att SIM card and it worked on their network.

Nope, your good to flash to your heart's desire lol
Quick question, sorry its a bit off topic, how did you guys get your phone unlocked?
I've read threads about Tmobile being friendly enough to send you a unlock code, but I currently have AT&T. Does that affect the process any?
Yes att does give out lock codes ... just have to wait a certain amount of days..and once unlocked always unlocked... flash away..

If your carrier is AT&T, i'd have to say that just going onto their web chat and asking the rep that you talk to if you could get the unlock code for your phone is probably the easier method. I did that about a month after i got my phone, on contract, telling them that i'd like to have my phone unlocked should something happen where i need to use the phone on another carrier. Didn't work with the first person i talked to, but the second person got me my unlock code.
You didn't search hard enough or at all.....

So tried this with my i747M and got the "connection problem or invalid MMI code" error. Phone is stock 4.1.1 on Rogers.
Edit: Figured out my issue, wasn't entering the * before the #197328640# code.
Looked like it worked fine for me, but don't have a sim card to test it with right now.

Seemed to work
The instructions completed without issue on Rogers galaxy s3 i747m 4.1.1 jellybean. I do not have a sim card to test the unlock with however, but lte and all other systems seem to be working.
has anyone tried this the other way around? I just followed the steps on my tmobile s3 but I can't verify since I don't have an att sim.
worked perfectly for me on bell , and I tested a telus sim and it worked perfectly!
Confirming that it works. Also, it's not that difficult. I did it in about 5 minutes.

[Q] Turning your T-mobile firmware into a factory firmware

Hello guys,
I am actually just starting to post here. So sorry in advance for anything wrong I do. I recently bought a Samsung Note 3. It is a phone locked to T-mobile. What I want to do is turn the phone's software into factory software (what I mean with that is the software that comes with factory unlocked phones). I really want it to be no different from an originally unlocked phone because I will use it abroad as well and I don't want all the software that comes with T-mobile. Is this possible? If yes, will it be any different from a factor unlocked phone?
This phone is the same as an unlocked note 3 except it has some extra tmobile apps.

Sim and region lock is apparently easy to remove with chainfire's app. Then just remove or freeze the bloat.
Who cares about region lock unless you go to Guatemala every Thursday.

Start at this link. I know a user with a T-Mobile phone that unlocked his sim to use it on ATT had the side effect of clearing the region lock, the op in this linked thread alludes to it in his post.

unlock tmobil s3 problems

I have an s3 that i was selling to mother in law to use on consumer cellular. T mobile provided an unlock code that does not work. They are supposedly investigating this. I tried to pay an online unlocker for a code, I told them the code t mobile provided that did not work, They were unable to generate an unlock code ,
What is is going on. T mobile sim locks phones and then cant provoide correct unlock codes??
What other option do i have?
This seems like a bunch of BS on tmobile part.
Selling to MiL ? I'd give for free if I were you.
Seriously speaking, you can take the phone to a T-Mobile store for further investigation. If the code does not work, don't try it repeatedly. The phone will lockup for good.
If the code did not work, make sure the T-Mobile Rep has taken down your IMEI correctly. Make them repeat it to make sure its correct.
There are other ways to unlock. But in order to try them, I need to know what android version you have right now. Its listed in Settings > About.
Its running stock rooted 4.3 with stocm recovery and some bloat removed. Have verified t mo has correct imei. Have tried 2 old centennial wireless sims and an old at&t sim. No luck.
Sent from my SM-N900T using xda app-developers app
Since you are on 4.3, the other way to unlock is out of question. Please take the phone to a T-Mo Store after you get the new unlock code.

I am having the same problem.
I just got done with TMO online chat and they said to make sure the WiFi is off before you do it.
I am going to try this when I get home.
Check out chainfires Region Lock Away app on the play store or here on xda. Its built for the note3 on 4.3 firmware, but ive seen claims it works on the S3 and others. I suggest reading the thread to be certain, but it may be a viable option for those running 4.3 rooted.

[Q] I just bought a N7100 however..

I just bought a N7100 however it seems to be network locked.
I could not find any unlocker who would provide network unlock code for Puerto Rico - Claro branded Samsung Note 2 N7100.
My only other option is to unlock it by code however I do not know which ROM/Kernel/modem combo would allow me to use the code
*#197328640#
The one that comes with the phone is Claro stock 4.3. I rooted it and flashed several stock 4.1.2 but the option "[6] Network Lock" and " [3] Perso SHA 256 " are not availble to change.
Can anyone tell me which ROM/kernel/modem would allow me to remove the network lock? Thanks in advance.
Take a look here, is for note 3, communicate with the developer maybe is possible to try at note 2 also.

None of the 4.1.1 stock would give me network unlock prompt via the hiden menu.
It was also difficult finding unlocking via imei because the imei unlock coxe database was off of latin america despite the fact that Puerto Rico belong to USA.
I just found a Canadian unlocker who used USB method. He unlocked my n7100 in 30 minutes through remote access. Cost was 20 US dollars. It has been working great so far.
I thought I was gonna be stuck with a unlockable phone thats as good as a dead brick. Anyhow Thanks for your help guys.
