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

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
Hey Guys,
I have had one heluva time trying to unlock my Rogers Galaxy s4. I purchased an unlock code, which did not work. I tried through service mode. Then I tried flashing the rom to a factory rom, which has now disabled my cellphone reception. At this point I am trying to put the stock rom back just get my phone working. Is there anything else I can do?
FastGSM.com has been the "last resort / saviour" for many here when service menu didnt unlock nor purchased-code.
fastgsm
I also used fastgsm to unlock mu i337m using the usb unlock method
Never try it but it could maybe help you out ;

Hi folks
This problem I have with this Australian L3 E400f is after I dial up 2945#*400# the unlock menu pops up as normal
selecting "network lock"
results in message "This phone is permanently locked and cannot be unlocked"
at no stage do I get a chance to input any unlock codes.
I gather there have been more than 10 failed attempts to input a NCK code, thou I am sure this is not the case it was straight out the box new.
the phone works just fine and dandy with all firmwares I have flashed as long as I have the telstra sim card in place.
I have used a Brazilian (V10D_00) stock firmware (using KDZ) hoping that the failed count lives in the firmware, it does not.
I have used CWM and flashed cynogen , this did nothing only the stock firmware allows 2945#*400#
gone back to my aussie V10D_00 telstra firmware and factory reset, then hardware reset..
I dont beleive this is a ROM issue. I am only guessing this is a EFS problem, anybody have any idea's if ADB or LGNSPT can get me out of this jam..
LGNSPT seems like a nightmare to get up and running and I have never used it before. I have once before on a samsung phone deleted the EFS folder (after backing up) and the phone generated a new EFS folder, I had my way with it then retsored the original EFS folder.
is their other methods of inputing the NCK code with ADB or else ?
thanks in advance this one has got me stumped...
all the best
Ok, I'm going to try to make a long story short, i hope that i've posted in the correct forum, I've been scouring this forum and others but nothing I've found has quite fixed my issue.
Got my S4 locked to Bell in Canada. Heard it was really easy to unlock [service menu *#0011# method] but once I got to Indonesia [for travel] expecting to be able to use my phone I found that the service menu was no longer available. Ok, no problem, there must be other ways;
I ended up paying for an unlock code from a site, it didn't work. In fact, immediately after I press 'unlock' it would say 'network unlock unsuccessful'.
I thought they gave me a faulty code but when the code I bought FROM Bell was the exact same one, and had the exact same problem I figured it was likely 'region locked'
I ended up flashing a stock rom with odin, one from a weird unlocking site, and eventually I got it working. The only problem was that whenever I'd go into screen lock I'd lose reception and have to airplane mode on and off to get it again.
After Indonesia I went to Turkey, was unable to connect at all with one of their service providers, but had no problems with Vodafone. I think this may have been a side effect of regionlock away app, I needed to use that as well.
Once I got back to Canada I went custom recovery with cwm and flashed Cyanogenmod. This was fine, no reception problems, 10.2 - 11 was all good.
NOW I am in Poland, and getting the same problem I had in the first place. Whatever Cyanogenmod did, re-locked my device, in some way, I'm guessing.
I'm now rooted, with TWP recovery, running Android 4.4.4 Dave GPE rom, and would REALLY like to be able to use my Polish sim card with this fantastic setup. Chainfire's regionlock away app does not work, gives me a CSC error message. My phone now says it's an i9505 instead of i337m
Anything I have overlooked? Any way I can get this fully unlocked and working the way I want it to?
*NOTE* I can't access *#0011# service menu, even though I flashed [i think] stock dialer.
You are not in the correct section
You need to be in this section.
http://forum.xda-developers.com/galaxy-s4-att/general
I can help you a little though. If the unlocking methodes fail, then it's usually because you don't have an older modem. You need to look for the modem you should flash in order for it to work. Afterwards you can flash the modem again you are on now. If you can't find it, just flash an old modem and try.
I find it hard to believe that Cyanogenmod could have caused this though.
Cool, that will be my next phase of attack. I appreciate the redirect and thoughts (Y)
So i have the smg935p but i am new to flashing roms and have been learning trial and error. I initially flashed a custom rom to the 9bit amd essentially soft bricked the phone. I did more research and flashed the stock rom(or so i thought) now my software version is G935AUCU8ARJ1. I have since had the phone unlocked by spint but now every sim i put into besides the original is showing invalid. Any ideas as ti what i can do about unlocking this phone to any carrier? I am currently using straight talk which i never wouldve switched if id known about the hotspot issue. Also if anyone knows how to bypass that issue that would also be wonderful. Can i perform this unlock or task of doing such without a computer?

If you previously owned it, you can try contacting Sprint to get it Sim unlocked. You might have better luck finding an unlock service on eBay though
