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

Updated mine through odin.. still unlocked.
thanks...i just updated with odin and mine is unlocked
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!
ive been trying to get my samsung s4 SGH-i337m Bell unlocked.
ive tried a few internet companies and they said they cant unlock the phone for many possibly reasons.
ive swapped the motherboard with a smashed screen phone because my first s4 had the sim card issues and many other issues so i swapped with a newer mobo.
now i want to unlock my phone to work with my carrier (wind mobile) but im not finding any ways to unlock it myself. ive tried using menus trying to unlock "PERSO SHA256 OFF" through the menu but i have 4.4.2 and 4.3 is the android version that can be unlocked easily through menu screens. once the phone is at 4.4.2 it seems like its unable to flash back to 4.3.
ive got the idea to change the IMEI so my phone will be basically original but with the newer mobo...but im having problems changing my IMEI.
ive used QPST and changed the hex code and reset the phone and it wont take and ive used NV reader and still doesnt seem to change the IMEI. each time i check my IMEI its still the original.
is there a way i can unlock it or change the IMEI to my first phone and use my first unlock code to unlock my phone with the new motherboard?
thanks
Changing your imei is illegal in many countries. You went get any support on doing that on XDA.

ok here is my problem
i have Samsung s5 from rogers
i when to Ghana so i wanted to use my phone there but it was lock so
took it to some guy to unlock it and it worked ok
when i came back and inserted my old sim
i get not registered to network and my imei is different from the box
i have tried flashing it with stock rom but still getting the same message
any body had this problem and how it they get it working
thanks
Unless you have made a backup of your original cert files nothing can be done, the shop in Ghana most likely used an IMEI from another handset and wrote it yours during the process this also unlocks your handset afaik .

Hi guys
I recently purchased an S4 from an on-line professional seller, the guy apparently owns a physical store but sells some phones on-line
when the phone arrived, I turned it on without the SIM, insert my home's wi-fi connection password, and the phone started to update both apps, and the OS to lollipop
I installed the backup I previously got from my old s3 mini, installed all my apps from playstore, and once I installed whatsapp, I turned the phone off, and than on again, this with my SIM since whatsapp has to confirm my number
The phone accepted my PIN code, whatsapp accepted my number and restored it's backup, but the phone also asked for this SIM network unlock pin
I told the guy what's happening, he told me he would send me a new phone, but I suspect this can go wrong
If that's the case, can anyone here tell me how can I overcome this SIM network unlock pin issue ?
thanks in advance
Regards
Antonio
If the phone were unlocked for use on any carrier, you would never see the SIM unlock pin request screen. Since you are seeing that screen, the phone is not unlocked.
To resolve this, root your phone and downgrade the phone's modem to an Android 4.2.2 version. Find a copy of RegionLock Away on XDA or through Google, copy it to your S4 and install it. Run it. Afterward, upgrade the modem to a more current version, and enjoy.
That's roughly what I had to do when the SIM unlock screen popped up on me.
Which s4 do you have? If it is the i337, region lock away may not work as you may not be able to downgrade the modem.
