Ok.. sooo.. Some people have gotten the JIC ota update from tmobile USA.. Well i decided to go ahead and update it. Well I lost the carrier unlock on it now.
I was just the stock rom on it rooted and unlocked using the one click unlock to get teh codes to unlock the phone. It worked then. Now with the JIC6 update i have lost that unlock. Also the one click unlock app to get the codes no longer works. I have also seen other post about using a hex editor to look at the nv_data.bin file to look for the unlock codes (no success). I have the original code from before the update, but it does not work. Is there a Way to unlock the vibrant with the JI6 update?
Just enter the same code you got last time. and it will unlock you.
If anyone else reads this. Please keep your code. and put it someplace safe. everytime you flash you will need to re-unlock most like a iphone.
Interseting that i didnt even have to reenter it. First when i updated and than checked teh network lock code showing that it was on so i than proceded to use the one click unlock app and it didnt not work. SO lucky for me i have a screenshot of the code when i first used the unlock app. so i did the same process and put in another carrier sim and entered the unlock code. It told me it was unsuccessful. Now that i went to try it again after my first post. I procceded to put in the other carrier sim card and it was unlocked.
Oh well. Thanks!

He says in the OP that he has the original code, but it doesn't work.
I know this is actually a known Samsung problem that has happened on many of their phones (even ones that came unlocked from what I've read) & generally re-entering the key works.
If it doesn't work for me, I'll call up TMO & complain. I bought the phone at retail price off contract, so they should give the code w/o a problem.
Generally as long as you've been a customer with them for at least 30-90 days (and your phone is beyond the returnable period), they'll give the unlock code if you call & ask for it. Sometimes you have to say that you'll be travelling out of country in order to get them to give it to you.
Is there a way to unlock without putting in a foreign SIM?
WTF !
Do you mean that updating the device to JI6 will lock the phone ?!
I unlocked mine with a code is that means I'll lose the unlock ?!
I discovered this a few weeks ago. I was working on a fix when I bricked my phone.
I just got my replacement on Tuesday and will be continuing the fix.
What happens is either something within the ODIN process, or on the rom itself puts a generic bml3 block on that contains all F's where the unlock code is stored.
I also know that it's stored on the nv_data.bin in the ./efs block.
I have been able to get my unlock code to be seen by the sgux program when modifying the bml3 file and pushing it back to my phone.
I will be working on nv_data next, though, seeing as my new phone has the unlock codes already, I'll have to do some editing and backing up.
I have my old codes with me so can someone confirm if old codes still works after the update ?
Thanks for sharing the information with us regarding phone. It may help us n the future.

Yeah after my original posts i think your old code will work. It will probably give an error of that it was unsuccessful. Just ignore it. and and just reboot the phone.
so basically to recap what i did.
updated JIC6 ota with tmobile.
checked network lock *#7465625# ( showing that the network lock was on.)
tried that software one click app to get code. (unsuccessful)
powered off phone
put in another carrier sim card.
bootup phone.
put in old code i had from before update to jic6 ( says that it was unsuccessful )
power off phone
put back Tmobile sim
power off phone
put other carrier sim in
unlocked!
i dont have tmobile sim ...do you think it needs that ?
I ran into this on my old vibrant running jfd. Unlocked and rooted and I needed to reflash jfd with odin. Phone relocked itself even reflashing same firmware. Efs data didn't change because the unlock code could still be retrieved. But when I inserted my att sim the code unlock said unsuccessful no matter what I tried. It never unlocked again.

So old codes didnt work for you and you are stuck.
can anyone confirm if we should update or not to remain unlocked ?
anyone confirming this ?
I got two different statements here
Ok, I updated my vibrant to JI6 today and it didn't lock my device !!
Since I don't use T-mobile data plan so I downloaded the leaked rom from (Vibrant Android development) section then I flashed the stock rom followed by JI6 ROM and it's working perfect !!
Maybe because mine is unlocked officially by T-Mobile code !
Or may be only ota is locking
We need more info

Now time to check whats new :d
They will not release a code nor will att for 9 months after the phone is out. You may call and ask.
Thats why i offer unlock services for these phones.
Successful OTA update yesterday, NO NETWORK LOCK, phone was rooted with no lag fix
Hello all
This is my first post here, but I have been reading a lot for some days now
So this is the issue
Some days ago I bought on ebay from a reputable seller the sgs2 stated as unlocked for all networks. This is a UK phone but I am located in portugal, and I use a vodafone sim card
Much to my surprise I was greeted with the O2 logo when turning it on.. oh well.. no big issue on that but...! right after entering my sim card pin code it asked for a network lock control key.!
Trying to avoid too much assle for being a newbie in android I bought an unlock code from mobileunlocked, and well, it didn´t work! says "requesting network unlock" over a fraction of a second and then right afterwards "network unlock request unsucessfull"
Ok, so I went the hard way and read all about firmware and rooting at the android development part of the forum
Was able to flash the XWKE7 / baseband XXKE4 with odin, was able to root it with intratech´s thourough instructions, no more O2 startups or logos, even installed the galaxy S2 sim unlock (it finds the same unlock code I got before, and it is probably right)
but.... the dam unlock code question does not go away, so I have no mobile network at all!
Seems it tries to communicate with O2 for the unlocking but of course I am nowhere near the UK..
So I have a fantastic up to date piece of brick in my hands!
Could someone please help, how can I get over this network unlock code ?
I am running out of options, please help!
best rgds
Buy a code from somewhere online instead. They're more reliable then the app unlock.
Samsung phones can be locked by 4 methods methods but generally the first three are what you are interested in .
1. [NCK] Network lock
2. [SCK] Subset lock
3. [SPCK] SP lock
4. [MCK]
o2 generally only lock down NCK
1 ensure you have down the correct IMEI number , when you got your network unlock code was it just the unlock code they gave you or did they supply the above too.
2. you do not need to have an O2 sim to unlock as the procedure means you need to put a different sim in to enable the codes .
3 mobileunlocked.co.uk are very good and if you contact them they will be able to help you . Send them an email .
Hope this helps but just make sure you entered the correct IMEI number *#06# from the start .
good morning
indeed they do, I bought from them. I had to enter the MCK and then the NCK
how could I know ? lolol
also thank you guys for your prompt help
turning on the little devil as I write... ta nan!
Hi guys!
I am sorry to open a new thread but i searched a long time and didnt find an answer to my problem.
I try to unlock my phone and first i found the free way someone explained here in the xda forum with the service mode. But when i enter *#0011# nothing happens. Even other combination dont work. The only one i know works is *#06# to see my IMEI number.
So now i bought an unlock code but even this dont work. I asked them to help me and they only say i have to do something ib the service mode but... U know service mode dont work.
Somewhere i read to flash another modem but this also didnt work (maybe i flashed the wrong one? I think it was something with ME2).
Now i have the liquid smooth rom 3.0 with android 4.4.2, baseband I9505XXUEMKE and PoKernel v2.0
I hope someone can help me.
Best Regards

- Unlock by Service Mode only worked for android 4.2.2.
- To enter unlock code in Samsung S4 do as following:
1. Once you have the code, insert a SIM card from a network different to the one your phone is locked to.
2. Upon starting up, you'll be requested to enter the "SIM network unlock code" - at this point, enter your unlock code.
3. The phone will read "successful" and your S4 is then completely unlocked.
OR
- Factory reset ur phone, flash one STOCK rom through ODIN and you will have service mode working again. Anyway you cant unlock it through SERVICE MODE under android 4.4.2.
Thank you gonna try it soon!
EDIT: Thanks Joku. I flashed 4.2.2 and then my unlock code worked. Also service mode worked. Thank you!!
I have a Samsung SGH-i437 that was a contract phone from AT&T. I wanted to unlock it for use over seas, so I rooted the phone and installed CyanogenMod cm-10.2-20130925-UNOFFICIAL-expressatt but the phone still has a carrier lock on it. I now have a unlock code but can not get the prompt by using #7465625*638*CODE# because it give me a no network message. When I insert a different sim it does not recognize it. It only has the icon for the sim with a ? make on it.
Any help would be appreciated!
4 days and no help!

Starting to think signing up was point less. It has been 4 days with no reply's!
Hi All - I recently bought a Samsung Galaxy S8 from someone else. It worked fine when I was with T-mobile but when I moved to another network and popped in a new SIM, it asked me to "Enter network unlock code". I figured it must be locked to T-mobile so I reached out to them. They said my account met all the unlock criteria and said they'll send me instructions via email. I got the email two days later saying I need to use the "Device Unlock App". However, there's no such app on phone and there's no way to install it either (its not in the Play Store). I went back to T-mobile and they said since the device wasn't purchased through T-mobile, its not be a T-mobile "branded" phone. My questions are:
1. If its not a T-mobile branded phone, why does it only work on the T-mobile network? I checked its not rooted. It doesn't have any T-mobile apps and doesn't show any splash screen with the T-mobile logo.
2. Someone said that Samsung GS8 locks to the network of the first SIM you put into an unlocked phone. Is that true?
3. T-mobile says they've "whitelisted" my IMEI, so if I can somehow get the Device Unlock app I may be able to unlock it. Any idea how I can do that? Do I need to flash the firmware and install the T-mobile version or is there another way.
Thanks!
If you need to app, you can try here: https://support.t-mobile.com/docs/DOC-14011
However, as your phone is asking for the unlock code, the app might work but not unlock your phone.
You really need to do a network check and see which network is your phone actually locked. If your phone needs unlocking code, you might need factory level codes.
