[Q] SIM Unlocking

I was wondering if there was a way to unlock the Galaxy SII for free. I know that you can use like adb to unlock the MyTouch 4G Slide. Can something one do something like that with this phone?
btw, I tried the "Galaxy S Unlock" app from the Play Store, and it didn't work.

Do what I did. Call tmobile and tell them that you are leaving the country for a while and want to use a different carrier to avoid roaming charges. Bam. I had my unlock code within 24 hours.

yeahhh. I know about that, but I don't like how you are supposed to wait 3 months in between unlocking. and i might actually leave the country in less than three months. and the other phone is neither unlocked nor rooted.

Nope, only way is to call T-Mobile for a code....or a third party vendor

Why not tell your carrier that you are going overseas and want to use your phone and ask them to unlock it I did and T-Mobile sent me the code for my phone at no charge. My problem is coming up with a non-tmobile sim card.

thanks but i tried that a while back. no such options for me

[Q] Note 2 Big Issue - PLEASE HELP!!!

Sorry I m a Beginner in the android world, so i will do my best to explain my issue
Please help me all help needed
1) I bought a Galaxy Note 2 from a person - he said that Note 2 was BLOCKED by T-mobile - I verified with T-mobile and the IMEI is indeed theirs and it is BLOCKED - so we know this is a REAL phone, NOT a clone
2) when I bought it he said that the phone was unlocked and is being used on AT&T - I verified and saw that he was using on AT&T network before he Reset everything and gave to me.
3) i went home and put in my AT&T sim and the screen read "Sim Network Unlock Pin" with Unlock and Dismiss button below. I thought this was the sim lock, so i removed the sim lock, but it still show that on the start screen - so here I thought that the Phone Might have been Un-Unlocked due to Reset.
4) I went ahead and follow the direction on how to unlock S3/Note 2 from XDA (http://forum.xda-developers.com/showthread.php?t=2014982), - btw i did this Successfully on 2 S3 before. Here is another problem: Under Lock Network screen (option 6) I cannot see option 4: [4] NW Lock NV Data INITIALLIZ (Does not exist) - So I have no way of unlocking it since this option is not available.
5) I thought that he did somekind of custom rom, but no - i checked and the Binary counter is 0 - phone status is Normal.
Please help me.
All I want is to use ATT now.
Please help me I will stay all Night till this is solved.
Thanks all in advance.
BTW attached is my About screen in case anyone have question.
*** second issue that we will talk later is - i have another note 2 bought directly from t-mobile with 4.1.2 - this one does not have [4] NW Lock NV Data INITIALLIZ . either. - how weird.
I check at the store and their note 2 4.1.2 HAS that option. !!! - we shall talk about this issue at another time

Can anyone please help me

No, i dont think they share blacklist. When i bought the phone it clearly showed att and use normally, then i took his sim out and reset the phone and brought it home. Test with T-mobile sim right away (i have both tmobile and ATT) - t-mobile say SEARCHING.... it is block so could not find any net work, but when i pop in at&T it said "Sim unlock pin"
Also the reason y i know t-mobile and att don't share the same black list is because i used a blocked s3 on att before

Oh, learned something new today!

hi,
i did some research and i think T-mobile and AT&T will potentially share the blacklist - but don't know it worked on my s3 before.
I just came up with an IDEA and would like to hear from Pros see if it will work.
What is if Install Samsung ROM - but the international version (usually my t-mobile i would download tar.md5 from t-mobile, same for att). What would happen to my phone if i download and install International rom - would it make my note 2 INTERNATIONAL - that mean it is NOT lock to any carrier?

I'm not sure how the store model had this option because it shouldn't. Anyways, use Odin to restore an older firmware then follow the unlock process and you'll be good.

^this. Should be on any 4.1.1 then you'll have the [4] option

You have to downgrade to the lj1 modem I think. Whatever was before ll4 then unlock then reflash mb4 modem

Stay clear from blacklisted phones. Solves this issue
I hope that blacklisted s3 was not the phone someone stole from me.. I would never buy a Black listed phone. I do know all of them are not blacklisted because reported stolen. But if you take the ability to sell them People will STOP STEALING THEM..
Just as a quick note. In The future it might be best to not Buy blacklisted or bad imei Phones.. Some are from contracts not fulfilled .. Questionable as to rather a carrier should be able to black list or not..
But equally number of them are STOLEN. What if it were your phone.
I so was not going to write this post . But it It really much different then software piracy or buying Stolen goods...
Just my opinion.. Ohh and yes i think the carriers are evil in near every way.
Good Luck and hope you get it fixed but only if it was not a Stolen phone. if it were . Well my above comment will tell you my thoughts.

Is there a way for you to talk to that person and ask him where he got the phone from? i hope this gets resolved ASAP

Hello all
Thanks for helping.
Indeed i have downgraded to 4.1.1 and now have 4 option and was able to unlock it for AT&T
However, i have a silly question that i hope to find a RIGHT answer.
I know that we can do Custom Rom for note 2 - however, I was wondering if we can install ATT OEM Rom to T-mobile note2, or T-mobile OEM Rom to AT&T note 2?
DOnt know if i made it clear enough.
Please help.
Thanks

Unlocking a sgn2 on O2 network (uk)

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?

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.

[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.

Can somebody answer the question,please.

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.
