Unlocked Phone locked again - Vibrant General

Hi there
I Unlocked my vibrant about a month ago amd this morning I powered it on and I was askef for thesim code numbers again. I was just wondering if anyone would know what would prompt this or have had this problem? Or if this is normal

I am going to unlock it again, but I just dont want to have this problem again.
Or is there anything on my phone in the settings I should have set off , so that phone will not automatically go locked again. Some how I am thinking maybe Bell might have put something on the network that was downloaded that changed the NV_data and re locked my phone... Not sure though... Any thoughts? Never heard of a phone that was unlocked being locked again randomly.
I used ADB Shell and changed the NV_Data file and it unlocked it for me.
I did not type in any 8 digit sim code. I have a backup of my original NV_Data file. For unlocking it should I copy and paste it back on to my phone or try to unlock it with the NV_data file that is currently on there now?
It is rooted but still in JFD, I am thinking of flashing the phone again to erase everything and start back fresh. The phone seems a lil buggy and slow.
Any help would be appreciated.
Thanks!

[Q] Official Tmobile JIC6 Update loses unlock

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

Unlocked Vibrant to Locked Vibrant

I unlocked my Vibrant originally, I had to go through a more complex way because when I did the original way of Unlocking it just gave me 00000000.
Randomly a month later, I turned on my phone after it was dead and it became locked again.
Does anyone know the reason for this or what might of caused this? This would be helpful as I do not want this problem to re occur again!
It is ****y too because I do not have a Sim Unlock code because the method I used dident give me one, it just asked me to put 00000000 in and when I tried to use that for the unlock code again it did not work.

Unlock Code Not work after odin back to stock

Need help I unlock my phone by code sent by t-mobile it worked fine.
Then I odin back to stock since CM7 was not working right.
When I odin back to stock I also clear the internal phone storage from under settings/ sd card.
Now when I boot up with at&t card and have to enter unlock code so I enter it but it says unlock network unsucessfull.
why doesn't the code work it used to work?
also does it have anything to do with clear phone storage and missing efs folder?
How do I get back the efs folder?
I solved it. I ran a market app galaxy S unlock
gave me a code of #FFFFFF say go to next step and backup my efs than patch it to unlock sim.. so I drag the efs folder to root and looks like all the efs files are back

[Q] L3 E400f ”This phone is permanently locked and cannot be unlocked”

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

[Q] How can I repair my IMEI on i9301i?

Hello folks,
I've read A LOT of threads here at the forum about repairing/recovering IMEI, but none specifically for the S3 Neo (GT-i9301i). Here is what happened with my cell: I bought it in the UK, brought it back to Brazil, and noticed that it was network locked (I did the region unlock while in Europe). Tried to unlock it by myself, rooted the device with ChainFire, but later, in order to send it to be unlocked in a local store, flashed the original stock ROM. The phone is unlocked now, but without the IMEI! When I hit the *#06#, it shows only the / ** numbers, the whole 15 digit number is now gone.
I have a backup from my efs folder that I did before sending the phone to the store, I installed GalaxS Unlock and did the backup. But when I access the backup, it doesn't have the .nv_data.bin and .nv_data.bin.md5 that every tutorial asks me to use it in the process. I tried the method of deleting my efs folder and restarting the phone, but that didn't worked either.
Is there something I can do to repair my phone?
Thanks
